Mode of Action

Prowl H20 is a meristematic inhibitor that interferes with

the plant’s cellular division or mitosis. This and/or other

products with the meristematic inhibiting mode of action

may not effectively control naturally occurring biotypes of

some of the weeds listed on this label. A weed biotype is a

5
naturally occurring plant within a given species that has a

slightly different, but distinct, genetic makeup from other

plants. Other herbicides with the medstematic inhibiting

mode of action include other dinitroaniline herbicides, such

as trifluralin. If naturally occurring meristematic inhibiting

resistant biotypes are present in a fietd, Prowl® H20

herbicide and/or any other meristematic inhibiting mode

of action herbicide should be tank mixed or applied

sequentially with an appropriate registered herbicide having a different mode of action to ensure control.

Application Rate

Use rates for Prowl H20 when used alone, in tank mix, or

for sequential applications are given in Crop-specific

Information, Use rates of this product v~ry by soil texture

and organic matter. See Table 3 for soil texture groupings

used in this label.

*Sometimes considered transitional soils and may be clasdr~ed as e~ther

medium- or line-textured soils,

For peat and muck soils. Prowl H~O may be used on peat

and muck soils, but weed control may be inconsistent and!or

reduced, Use maximum labeled use rate allowed in the spec~c

crop.

Application Timings

Prowl H20 will provide most effective weed control when

applied by ground or aerial equipment and subsequently

incorporated into soil by rainfall, sprinkler irrigation, or

mechanical tillage prior to weed seedling germination.

Prowl H20 can also be applied through chemigation,

including flooded basin irrigation systems. Prowl H20 is

recommended for preplant surface, preplant incorporated,

surface incorporated, preemergence, early postemergence, postemergence incorporated (CULTI-SPRAY) or

layby treatment. See Crop-specific Information for specific application directions and restrictions by crop.

Preplant Surface Application. For use in minimum

tillage or no-tillage production systems, apply Prowl H20

alone or in tank mixes up to 45 days before planting.

When making early preplant surface applications (15 to

45 days prior to planting), Prowl 1-120 should be tank

mixed or followed by a postemergence 6erbicide application. Rainfall or sprinkler irrigation after application is

required to move this product into the upper soil surface

where weed seeds germinate.

Preplant Incorporated Application. Apply Prowl H20

and incorporate into the upper (1 inch to 2 inches) soil surface up to 60 days before planting. Use an implement

capable of giving uniform incorporation; two-pass incorporation usually results in a more consistent result.

Surface Incorporated Application. Uniformly apply

Prowl H20 as broadcast or banded treatment to soil surface underneath established trees and/or in ground areas

between trees rows. Incorporate into upper (1 inch to

2 inches) soil surface using either rainfall, sprinkler irrigation, or shallow mechanical incorporation using an

implement capable of giving uniform incorporation; twopass mechanical incorporation usually results in a more

consistent result.

Preemergence Surface Application. Broadcast treatment uniformly to the soil surface at plantirig and up to

2 days after planting. Rainfall, sprinkler irrigation, or shallow mechanical incorporation after application is required

to move this product into the upper soil surface where

weed seeds germinate. If adequate rainfall or irrigation

does not occur and weed seedling emergence begins, a

shallow cultivation or rotary hoeing will improve

performance.

Early Postemergence Application. Prowl H20 must be

applied prior to weed seedling emergence or in a tank mix

with products that control the emerged weeds. Refer to

Crop-specific Information for specific postemergence

application recommendations by crop.

Postemergence Incorporated Application (CULTISPRAY). Prior to application, crop must be cultivated in

such a manner as to throw at least 1 inch of soil over the

base of the crop plants. This will prevent direct contact of

Prowl H~O and the zone of brace root formation.

Prowl H~O must be applied broadcast with a ground

sprayer when crop is at least 4 inches tall up to laybF Use

drop nozzles if crop foliage will prevent uniform coverage

of the soil surface within the rows. Thoroughly and uniformly incorporate Prowl H~O treatments into the soil:

1. With a sweep-type or rolling cultivator set to provide

thoroQgh incorporation in the top 1 inch of soil, or

2. With adequate overhead irrigation water or rainfall. See

Crop-specific Information (Corn and Grain

Sorghum) for more details on (CULTI-SPRAY)

application.

Layby Application. Apply Prowl H20 directly to the soil

between rows as a directed spray following the last normal

cultivation (layby). See Crop-specific Information for

more details on layby application.

Split Application. Prowl H~O may be applied preplant

incorporated up to 60 days prior to planting and followed

by a preemergence application at planting or up to 2 days

after planting. The total amount of Prowl H~O applied per

acre per season cannot exceed the highest labeled rate

for any given soil type. See Crop-specific Information

for more details on split applications,

Fall Application. Prowl H20 may be used in fall applica~

tion programs in car[ale crops, See Crop-specific

Information for details on fail application timing.
Spraying Instructions

Prowl® H20 herbicide may be applied [Jsing either water

or sprayable fluid fertilizer (such as straight 32-0-0 or

28-0-0) as the spray carrier, Additionally, Prowl H20 may

be impregnated on dry bulk fertiIizer. Sprayable fluid fertilizer as a carrier is NOT recommended for use after crop

emergence unless the typical fertilizer burn symptoms on

the crop are acceptable,

Aerial Application

Uniformly apply in 5 or more gallons of v~ater per acre.

Exercise caution to minimize drift. DO NOT apply 8uring

periods of gusty winds or when wind conditions favor drifting. Spray drift can cause injury to sensitive crops. Use a

flagman or an automatic mechanical flagging unit on the

aircraft to avoid overlapping and possible crop injury.

Ground Application (Broadcast)

Uniformly apply with properly calibrated ground equipment

in 10 or more gallons of water per acre or 20 or more gallons of liquid fertilizer per acre. Use sprayers equipped

with appropriate nozzles that provide uniform and accurate

spray distribution and minimize drift. Keep the bypass line

on or near the bottom of the tank to minimize foaming.

Nozzle and in-line screens must be no finer than 50 mesh.

Application of Prowl 1420 during periods of gusty winds

may result in uneven applications. DO NOT apply

Prowl H20 postemergence in liquid fertilizers.

If liquid fertilizer/herbicide(s) mixture separates in the spray

tank, clogged equipment and uneven application can

result. Always predetermine the compatibility of

Prowl 1-120 alone or with other herbicides based on the

following compatibility jar test:

1, Add 1 pint of fertilizer to a quart jar.

2, Add 1 to 4 teaspoon(s) of the dry flowable (DF), wet~

table powder {WP), aqueous solution {AS), flowable (F)

or liquid (L) formulation (depending on" mixing ratio

required) to the liquid fertilizer. Determine the number of

teaspoons of the formulation to add by the following

formula:

Ibs or pts of producVacre teaspoons of herbicide to

gallons of fer~iIizer/acre x 11.4 = add to 1 pint of fertilizer

3.Close the jar and agitate until the herbicide(s) are evenly

dispersed in the liquid fertilizer. If the materials do not

disperse well, it may be necessary to slurry the chemicals in water before adding to the fertilizer.

4. After dispersing the materials, add appropriate number

of teaspoons of Prowl 1-120 to the jar and shake well.

Add water soluble concentrate herbicides to the mixture

last and agitate. Let the mixture stand for 30 minutes;

then observe the results. Lqok for signs of separation:

an oily layer or globules, sludge, flakes or other

precipitates.

5. Evaluate compatibility.

a. If the herbicide(s) and liquid fertilizer mixture does not

separate, use this mixture in your spray tank.

b. if the mixture separates but mixes readily with shaking, the mixture can be used provided that good

agitation is maintained in the spray tank.

c. If separation of the mixture occurs and agitation does

not correct this problem, a compatibility agent is

needed.

6. If the need for a compatibility agent is demonstrated,

the following procedure is recommended: Using a clean

quart jar, repeat step 1 above and add 1/2 teaspoon of

the compatibility agent to the liquid fertilizer. Mix well

and repeat steps .2, 3 and 4. If separation or precipitation occurs with the compatibility agent, DO NOT use

Prowl H20 with that specific liquid fertilizer.

Ground Application (Band)

Uniformly apply the broadcast equivalent rate and volume

per acre, T° determine:

band width in inches broadcast rate band rate

x

row width in inches per acre per acre

band width in inches broadcast band volume

row width in inches x volume per acre = peracre

Ground Application (Dry Bulk Fertilizer)

Apply Prowl H20/dry bulk fertilizer mixtures only with

ground equipment, DO NOT impregnate Prowl H20 onto

coated ammonium nitrate or limestone because these

materials will not absorb the herbicide, Dry fertilizer blends

containing mixtures of ammonium nitrate or limestone may

be impregnated with Prowl H20. A minimum of

200 pounds of impregnated dry bulk fertilizer, excluding

the weight of ammonium nitrate or limestone, must be

applied per acre,

Use the following formula to determine the amount of

Prowl H20 to be impregnated on a ton of dry bulk fertilizer based on the rate of fertilizer to be applied per acre:

2000 Prowl H~O Prowl H20 per

pounds of dry x (rate per acre) = ton of fertilizer

fertilizer per acre

To impregnate Prowl H20 on bulk fertilizer, use a closed

rotary-drum mixer or other commonly used dry bulk fertilizer blender equipped with suitable spray equipment. Spray

nozzles must be placed to provide uniform coverage of

Prowl H20 onto the fertilizer during mixing.

Apply the Prowl H20/dry bulk fertilizer mixture with an

accurately calibrated dry fertilizer spreader. The

Prowl H20/dry bulk fertilizer mixture must be spread uniformly on the soil surface.

Chemigation Application via Sprinkler

Irrigation and Drip Irrigation Systems

Prowl H20 may be applied as a chemigation treatment

through sprinkler irrigation and drip irrigation systems,

Refer to Crop-specific Information sections for

individual crops, DO NOT apply Prowl H20 via chemigation to crops unless specified in Crop-specific

Information section,
Apply this product ONLY through a sprinkler irrigation system of the following type: center pivot, lateral move, end

tow, side (wheel) roll, traveler, big gun, solid set, or hand

move,

Apply this product ONLY through a drip.irrigation system

that has emitters above the soil surface.

sprinkler irrigation or drip irrigation system, to inject = S

Unif(~rm distribution of Prowl® H20 herbicide-treated irrigation water is the sole responsibility of the applicator and

is required to avoid crop inju~ lack of herbicide effectiveness or illegal pesticide residues in the crop. If you have

any questions about calibration, contact .State Extension

Service specialists, equipment manufacturers, or other

experts.

The system must be properly calibrated (with water only)

to ensure that the amount of Prowl H~O applied corresponds to the specified rate. Apply Prowl H~O in 1/2 to

3/4 inch of water during the first sprinkler set (use at least

1 inch of water in the states of New Mexico, Oklahoma

and Texas). BASF recommends that Prowl H20 is mixed

with water at a 1:1 ratio in the injection nurse tank to

assist with product flowability, Maintain agitation in the

injection nurse tank to keep a uniform herbicide suspension dudng application. When application is complete,

flush the system with water,

Chemigation Instructions

(for low-volume micro sprinklers)

Output of low-volume sprinkler equals 4 to 50 gallons per

hour (gph) per emitter. Point of application MUST be

above ground.

Irrigation system should run a sufficient amount of time

prior to Prowl H~O injection to have all emitters functioning properly. After system is operating properly, length of

injection should be such that at one period of time during

the injection, the first and last emitters in the system contain Prowl H~O-treated water. Add Prowl H20 to the

supply tank already filled with the volume of water required

for the injection period. Maintain proper agitation in

Prowl H~O injection tank. Mix Prowl H20 in clean water

and inject down-line from filters. Following Prowl H20

injection, flush system for a period of time sufficient to

clear the line of Prowl H~O. (If Prowl H20 is applied during a normal irrigation cycle, make injection during the last

stage.)

Chemigation Calibration

(for low-volume micro sprinklers)

Calculation of use rate is based on wetted area around

emitters - NOT on tree acres. To determine correct

amount of Prowl H~O, use the following formula:

1, Treated area per each emitter = A

A = 3.14 x (radius x radius)

2. The area in square feet B = A x emitters/acre wet in each acre = B 144

C

S - x R = qts of Prowl H20 43,560

Example:

If the average distance from emitter to perime’~er of wetted area

measured 1 inch below soil surface is 13 inches, then

A = 3.14 x (13 inches x 13 inches),

and A = 530,7 square inches

tf there are 300 emitters per acre, then

B = 530.7 x 300 and B = 1105.6 square feet

144 wetted per acre

If the system covers 20 acres, then

C = 1105.6 square feet per acre x 20 acres and

C = 22,112 square feet wetted by system

If the desired application rate per treated acre is

2,0 qts of Prowl H~O, then

S= ~ x 2.0 and S = 1.0qt = amount of Prowl H20 43,560 to inject into the system

Special Precautions for Chemigation

1. DO NOT apply when wind speed favors drift beyond

the area intended for treatment.

2. DO NOT connect an irrigation system used for pesticide application to a public water system unless the

pesticide label prescribed safety devices for public

water systems are in place,

3. A person knowledgeable of the chemigation system and

responsible for its operation, or under the supervision of

the responsible person, shall shut the system down and

make necessary adjustments should the need arise.

4. Tail water (runoff water) from chemigation that contains

Prowl H~O should be recirculated and!or contained in

the field in a cistern or holding reservoir from the initial

application and/or used only on adjacent, approved

crops for which Prowl H20 is registered for this type of

application.

5. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the

flow of fluid back toward the injection pump. It must

also contain a functional, normally closed, solenoidoperated valve located on the intake side of the injection pump and connected to the system interlock to

prevent fluid from being withdrawn from the ~upply tank

when the irrigation system is either automatically or

manually shut down.

6. The Sprinkler chemigation system must contain a functional check valve, vacuum relief valve, and lowpressure drai~ appropriately located on the irrigation

pipeline to prevent water source contamination from

backflow. In addition, systems must use a metering
pump, such as a positive displacement injection pump

(e.g. diaphrdgm pump) effectively designed and cons~ructed of materials that are compatible with pesticides

and capable of being fitted with a system interlock.

7. The sprinkler chemigation system must contain functional interlocking controls to automatically shut off the

pesticide injection pump when the water pump motor

stops, or in cases where there is no water pump, when

the water pressure decreases to the 15oint where pesticide distribution is adversely affected.

8. The irrigation line or water pump must include a functional pressure switch that will stop the water pump

motor when the water pressure decreases to the point

where pesticide distribution is adversely affected.

1. Public water system means a system’for the provision

to the public of piped water for human consumption if

such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily

at least 60 days out of the year.

2. Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone

backflow preventer (RPZ) or the functional equivalent in

the water supply line upstream from the point of pesticide introduction. As an option to the .RPZ, the water

from the public water system should be discharged into

a reservoir tank prior to pesticide introduction. There

shall be a complete physical break (air gap) between the

outlet end of the fill pipe and the top or overflow rim of

the reservoir tank of at least twice the inside diameter of

the fill pipe.

3. All chemigation systems connected to public water systems must also follow restrictions listed in the preceding

section titled Chemigation,

Applications via Flood, Flooded Basin, or

Gravity Flow Irrigation Systems

Prowl® H20 herbicide may be applied via flood, flooded

basin, or gravity flow irrigation systems, but only to the following crops: bearing and nonbearing fruit and nut trees,

bearing and nonbearing olive trees, bearing and nonbearing vineyards, and alfalfa,

Use Instructions and Precautions for Flood,

Flooded Basin, and Gravity Flow Irrigation

1. Prowl H20 may be applied through flood, flooded

basin, or gravity flow irrigation systems designed to

uniformly distribute irrigation water along the soil surface. Solid set systems utilizing tall riser for overhead

application are excluded.

2. Follow all label directions for Prowl H20 regarding

rates per acre, timing of application,.and crop-specific

restrictions and limitations.

3. DO NOT connect an irrigation system used for pesticide application to a public water system unless the

pesticide label prescribed safety devices for public

water systems are in place.

4.A person knowledgeable of the chemigation system

and responsible for its operation, or under the supewision of the responsible person, shall shut the system

down and make necessary adjustments should the

need arise.

5. BASF recommends that Prowl H20 is mixed with

water at a 1:1 ratio in the injection nurse tank to assist

with product flowability. Maintain agitation in the

injection nurse tank to keep a uniform herbicide

suspension during application. When application is

complete, flush the system with water.

6. Systems using a gravity-flow pesticide dispensing system must meter the pesticide in the water at the head

of the field downstream of a hydraulic discontinuity,

such as a drop structure or weir box, to decrease

potential for water source contamination from backflow water.

7. Tail water (runoff water) from flood, flooded basin, or

gravity flow irrigation that contains Prowl H~O should

be recirculated and/or contained in the field in a cistern or holding reservoir from the initial application

and/or used only on adjacent approved crops for

which Prowl H~O is registered for this type of

application.

8. Systems utilizing a pressurized water and pesticide

injection system must meet the following

requirements:

 ̄ The system must contain a functional check valve,

vacuum relief valve, and low-pressure drain appropriately located in the irrigation pipe to prevent water

source contamination from backflow.

 ̄ The pesticide injection pipeline must contain a functional, aQtomatic, quick-closing check valve to prevent flow of fluids back toward the injection pump.

 ̄ The pesticide injection pipeline must also contain a

functional, normally closed solenoid-operated valve

located on the intake side of the injection pump and

connected to the system interlock to prevent fluid

from being withdrawn from the supply tank when

the irrigation system is either automatically or manually shut down.

 ̄ The system must contain a functional interlocking

control to automatically shut off the pesticide injection pump when the water pump stops.

 ̄ The irrigation pipe or water pump must include a

functional pressure switch, which will stop the pump

motor when the water pressure decreases to the

point where pesticide distribution is adversely

affected.

 ̄ Systems r~ust use a metering pump, such as a

positive displacement injection pump (e.g. diaphragm pump) of effective design and constructed

of materials that are compatible with pesticides and

capable of being fitted with a system interlock;

 ̄ Any alternative to the above safety devices must

conform to the list of EPA-approved alternative

devices.

9
9. Be sure to regularly measure the flow in the field to

ensure the correct amount of ProwP H20 herbicide

is metered into the irrigation water and also regularly

monitor to ensure that treated water is uniformly distributed across the field, Flow rates through metering

devices and distribution of Prowl H20 can vary with

water temperature and speed of water flow across the

field.

10, Uniform distribution of Prowl H204reated irrigation

water is the sole responsibility of the applicator and is

required to avoid crop inju~ lack of herbicide effectiveness, or illegal pesticide residues in the crop,

11. If you have questions about calibration, contact State

Extension Service specialists, equipment manufacturers or other exper[s.

Managing Off-target Movement

Spray Drift

Avoiding spray drift at the application site is the responsibility of the applicator and the grower. The interaction of

many equipmenbrelated and weather-related factors

determines the potential for spray drift, The applicator and

grower are responsible for considering all these factors

when making decisions. It is the responsibility of the applicator to avoid spray drift onto nontarget areas,

The following drift management requirements must be

followed to avoid off-target drift movement from aerial

applications to agricultural field crops:

1. The distance of the outermost nozzles on the boom

must not exceed 3/4 the length of the fixed wingspan or

rotor blade diameter,

2. Nozzles must always point backward parallel with the

airstream and never be pointed downward more than

45 degrees,

Where states have more stringent regulations, they must

be observed,

The applicator Should be familiar with and take into

account the information covered in the following spray drift

reduction advisory information.

Information On Droplet Size

The most effective way to reduce drift potential is to apply

large droplets. The best drift management strategy is to

apply the largest droplets that provide sk~fficient coverage

and control. Applying larger droplets reduces drift potential

but will not prevent drift if applications are made improperly or under unfavorable environmental conditions (see

Wind; Temperature and Humidity; and Temperature

Inversions).

Controlling droplet size:

Volume. Use high flow rate nozzles to apply the highest

practical spray volume. Nozzles with higl?er rated flows

produce larger droplets.

Pressure. DO NOT exceed the nozzle manufacturer’s

recommended pressures. For many nozzle types, lower

pressure produces larger droplets. When high flow rates

are needed, use higher flow rate nozzles instead of

increasing pressure.

Number of Nozzles. Use the minimum number of nozzles that provide uniform coverage.

Nozzle Orientation, Orienting nozzles so that the spray is

released parallel to the airstream produces larger droplets

than other orientations and is recommended practice.

Significant deflection from the horizontal will reduce droplet

size and increase drift potential.

Nozzle Type, Use a nozzle type that is designed for the

intended application. With most nozzle types, narrower

spray angles produce larger droplets. Consider using lowdrift nozzles. Solid- or straight-stream nozzles odented

straight back produce the largest droplets and the lowest

drift. Apply only as a medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or

greater for spinning atomizer nozzles.

Application Height

Making applications at the lowest height that is safe

reduces exposure of droplets to evaporation and wind.

Applications should not be made at a height greater than

10 feet above the top of the largest plants unless a greater

height is required for aircraft safety. DO NOT apply with a

nozzle height greater than 4 feet above th~ crop canopy

(for ground application).

Swath Adjustment

When applications are made with a crosswind, the swath

will be displaced downwind. Therefore, on the upwind and

downwind edges of the field, the applicator must compensate for this displacement by adjusting the path o)’ the

aircraft upwind. Swath adjustment distance should

increase with increasing drift, potential (higher wind, smaller

droplets, etc.).

Wind

Drift potential is lowest between wind speeds of 2 to

10 mph. Apply only when the wind speed is 2 to 10 mph

at the application site, However, many factors, including

droplet size and equipment type, determine ddft potential

at any given speed. Application should be avoided below

2 mph due to variable wind direction and high inversion

potential.

NOTE: Local terrain can influence wind patterns. Every

applicator should be familiar with local wind patterns and

how they affect spray drift.

Temperature and Humidity

When making applications in low relative humidity, set up

equipment to produce larger droplets to compensate for

evaporation. Droplet evaporation is most severe when

conditions are both hot and dry.

Temperature Inversions

Applications shall not occur during a temperature inversion

because drift potential is high. Temperature inversions

restrict vertical air mixing that causes small suspended

droplets to remain in a concentrated cloud. This cloud can

move in unpredictable directions because of the light,

variable winds common during inversions. Temperature

10
inversions are characterized by increasing temperatures

with altitude and are common on nights with limited cloud

cover and light-to-no wind. They begin to form as the sun

sets and often continue into the morning. Their presence

can be indicated by ground fog; however, if fog is not

present, inversions can also be identified by the movement

of smoke from a ground source or an aircraft smoke

generator. Smoke that layers and moves laterally in a corn

centrated Cloud (under low wind conditions) indicates an

inversion, while smoke that moves upward and rapidly

dissipates indicates good vertical air mixing.

Sensitive Areas

This pesticide should only be applied when the potential

for drift to adjacent sensitive areas (e.g. residential areas,

bodies of water, known habitat for threatened or endangered species, or nontarget crops or plants) is minimal

(e.g. when wind is blowing away from the sensitive areas).

DO NOT apply when wind conditions will allow the drift to

adjacent, susceptible crops.

Additives

Spray adjuvants have little or no influence on performance

of Prowl® H20 herbicide when applications are made

prior ~o weed emergence. However, several tank mixes

with Prowl H20 require adjuvants to improve burndown of

emerged weeds, Therefore, surfactants, liquid fertilizer

(28%, 30%, or 32% UAN [urea ammonium nitrate] or AMS

[ammonium sulfate]), or crop oil concentrate may be used

with Prowl H20 tank mixes applied prelSlant, preemergence, or early postemergence to the crop. Follow the

adjuvant recommendations on the tank mix partner’s label.

The recommended adjuvants must contain ingredients

accepted by the Environmental Protection Agency.

When an adjuvant is to be used with this product, BASF

recommends the use of a Chemical Producers and

Distributors Association certified adjuvant.

Tank Mixing Information

Prowl H20 may be applied in a tank mix or a sequential

application with other herbicides registered for use in a

given crop. Refer to the companion label for weeds controlled in addition to Prowl H20 alone.

When using tank mixtures or sequen{ial applications with

Pro~,111-120, always read the companion product label(s)

to determine the specific use rates by s6il types, weed

and agitate. Prior to mixing Prowl H20 or Prowl H20

tank mixtures in liquid fertilizer, refer to appropriate label

sections for recommended uses in liquid fertilizer, application instructions, and compatibility determinations.

NOTE: Prowl H20 will NOT mix in high salt formulation

fertilizers, such as 10~34-0. When utilizing high salt formulation fertilizers as the spray carrier, use one of the

following:

a. Pre~sluny Prowl H20 in water prior to adding to

tank; use 1:1 ratio of water to Prowl H20.

b. Add water to fertilizer solution prior to adding

Prowl H20. The amount of water should be equal to

or greater than the amount of Prowl H20 to be

used.

2, Prowl H20 Alone

When using Prowl H20 alone, add Prowl H20 to the

partially filled tank while agitating; then fill the remainder

of the tank with water or liquid fertilizer.

3. Prowl H20 Tank Mixes

Add the tank mixture ingredients in the fbllowing order

before adding Prowl H20:

a. Wettable Powder 0NP) formulations. Make a

slurry of the WP in water (1:2 ratio). Add the slurry

slowly into the partially filled tank while agitating.

b, Dry Flowable (DF)/Wa~ter-dJspersible Granule

(WDG) formulations. Add the granules to the partially filled tank while agitating. Make a Slurry of the

granules in water before adding to liquid fertilizer.

c. Flowable (F) formulations. Add the F formulation

to the partially filled tank while agitating.

d. Add Prowl H20 to the partially filled tank while

agitating.

e. Water-soluble Concentrate 0NSC) formulations.

Add the WSC formulation to the partially filled tank

. while agitating.

f, Emulsifiable Concentrate (EC) formulations.

Add the EC formulation to the partially filled tank

replanted without adverse effects the same year (see

Crop-specific Information for exceptions). If replanting

is necessary, DO NOT work the soil deeper than the

treated zone.

 ̄ Refer to Crop-specific Information for crop-specific

preharvest intervals and feeding and grazing restrictions.

Crop Rotation Restrictions

 ̄ Use of Prowl H~O in accordance with label directions is

expected to result in normal growth of rotational crops in

most situations’, however, various environmental and

agronomic factors, such as arid conditions, make it

impossible to eliminate all risks associated with the use

of this product and, therefore, rotational crop injury is

always possible. Soil characteristics and environmental

conditions which may contribute to crop stress that may

be accentuated by the use of Prowl H20 include:

coarse soils, compaction, high salinity, eroded knolls/hilltops, cold and/or wet soils, drought, and heaw rainfall

soon after application.

 ̄ When Prowl H20 is used in tank mix or sequential combinations, refer to label of other herbicides for additional

rotational crop restrictions.

 ̄ Restrictions for rotational cropping after the use of

Prowl H20 are dependent on the application use

rate of Prowl H20 in the primary crop. The user

should thoroughly read the following restrictions to

determine the rotational crops for their specific situation, according to application use rate.

 ̄ [Alternate label text until review of Limited Rotational F~eld

Accumulation study, MRID 47891605, is completed] For

crops which can be rotated the following year after application of Prowl H20, the minimum plant back interval is

Use Area

Crop-specific Information

Crop Injury Disclaimer. Prowl H20 use may result in

crop injury, loss or damage to certain crops under a number of conditions, including but not limited ~o agronomic,

cultural, mechanical, and environmental. Numerous risks of

loss or damage to certain crops may be associated with

the use of Prowl H20 even when directions for use are

followed completely. The user or grower should take all

such risks into consideration before deciding to apply the

product. BASF recommends testing on a small pot*

tion of the target crop to determine if damage is

likely to occur, Each grower who is considering the

product for such use should test Prowl H20 to determine

its suitability. A grower should use Prowl H20 only to the

extent that, in his sole opinion, the benefit of Prowl H20

use outweighs the potential injury to the grower’s crop.

In addition, many factors can affect crop growth and/or

yield, including but not limited to insects, diseases, weed

competition, poor seed quality, improper planting depth,

mechanical cultivation, poor weather (such as freezing or

excessive wind, rain, heat, or cold), lack of or excessive

moisture, crusting, fertility, or hardpans. Risk of loss or

damage to crops may be associated with the use of

Prowl H20 and contribute to poor stands due to failure of

crop to emerge, swelling of roots or other below-ground

plant parts, less vigorous plant growth and development,

and reduction in yield potential. Prowl H20 may aJso

cause injury to sensitive rotational crops.

Prowl H20 may be applied by ground; by air; by chemi~

gation; by flood, flooded basin, and gravity flow irrigation

systems; or on dry bulk fertilizer.

postemergence incorporated (CULTI-SPRAY) application in

field com.

Prowl H20 may be applied in conventional tillage as a

preemergence or postemergence application in field seed

corn, popcorn, popcorn seed corn, and fresh sweet corn.

Regardless of tillage system, plant corn at least

1-1/2 inches deep and completely cover with soil.

In conventional tillage systems, plant into a seedbed that is

firm and free of clods and trash. Use only where adequate

tillage is practiced to provide good soil coverage of the

corn seed,

in no-till systems, utilize a no-till planter that is capable of

planting through crop residue. Ti~e use of no-till planters

under conditions that do not allow good.soil coverage of

19

the corn seed can result in reduced crop stand or injury if

Prowl H20 contacts the germinating corn seed. Check

equipment to ensure good seed coverage.

Prowl H~O or Prowl H20 tank mix combination treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received after application. If cultivation is necessary because of soil crusting

or weed germination, use shallow tillage and make certain

corn seeds are below the tilled area.

Additional Weeds Controlled. In addition to the weeds

listed in Table 2, Prowl H20 will control the following

weeds in corn with CULTI-SPRAY application: wild proso

millet and shattercane.

Use Methods and Timings

Preemergence. Apply after planting but before weeds

germinate and crop emerges.

Postemergence. Apply postemergence until field corn is

30 inches tall (20 inbhes to 24 inches tall for pop, seed

and flesh sweet corn) or in the V8 growth stage, whichever is more restrictive. If the corn canopy prevents applications from reaching the soil, use drop nozzles and apply

as a directed spray.

CULTI-SPRAY. Apply Prowl H20 alone or Prowl H20

plus atrazine when field corn is at least 4 inches tall until

last cultivation (layby). Prowl H~O plus atrazine must be

applied before the field corn reaches 12 inches in height.

DO NOT exceed 1.2 Ibs ai per acre of atrazine, as

specified on the atrazine label. Under situations of low

rainfall or soil moisture, when deep germinating weeds

such as shattercane or field sandbur are anticipated,

mechanical incorporation will provide best results. If cultivation is needed after application and incorporation of

Prowl H20, the depth of cut should be no deeper than

the depth of cut used to incorporate.

Prowl H~O may be applied by ground, air, or chemigation

in conventional, minimum, stale seedbed, or no-till as a

preplant surface, preplant incorporated, preemergence,

layby or postemergence application in cotton.

Pmplant surface, preemergence, layby and postemergence treatments are most effective in controlling weeds

when adequate rainfall or overhead irrigation is received

after application. A shallow cultivation is recommended if

soil crusting or soil compaction occurs, If weeds begin to

germinate or adequate moisture is not r~ceived after application, use shallow tillage (rotary hoe or light harrow) and

make sure cotton seeds are below tilled area. The use of a

postemergence herbicide treatment may be required to

control weed escapes at planting or following cotton

emergence.

Additional Weeds Suppressed. In addition to the weeds

listed in Table 2, Prowl H20 will suppress Russian thistle

in the state of Arizona.

cotton,

6. Postemergence. Prowl H~O may be applied by

ground or air as a broadcast over-the-top postemergence

application in cotton.

Postemergence treatments are most effective in controlling

weeds when adequate rainfall or overhead irrigation is

received after application. Applications before weeds germinate or after clean cultivation to remove existing weeds

are necessary because Prowl H20 will not control weeds

that are emerged at time of application. The use of a postemergence herbicide treatment is required to control

emerged weeds,

Prowl H~O may be used alone or tank mixed with

Roundup PowerMAX® herbicide (on Roundup Ready

cotton or Roundup Ready Flex cotton)~ Roundup

applied in the spring. DO NOT exceed a cumulative total

of 4.2 quarts of Prowl® 1-120 herbicide per acre in any

one crop season.

In both warm-season and cool-season perennial grasses,

use the higher application rate of Prowl .I-120 where more

dense infestations of targeted annual grasses, annual

broadleaf, or volunteer grass seedlings are anticipated, or

when a longer duration of residual weed control is desired.

Excess grass straw and crop residue from the previous

harvest should be evenly spread or removed by such

methods as crew cutting, propane flaming, or open field

burning (when local regulations allow) prior to Prowl 1-120

application, or reduced weed control may result.

Prowl 1420 may be applied in a sequential use program or

as a tank mix with other registered herbicides that control

emerged weeds.

Prowl H~O may cause temporary injury to perennial grass

stands. Applications made in periods of cold temperatures

that temporarily limit normal crop growth or in extended

cold temperature periods that initiate winter dormancy in

grass crops may result in crop injury. Diseases, extremely

cold weather, drought, extensive frost he.aving, low or high

pH, or salinity may weaken stands and make them more

susceptible to herbicidal damage.

Prowl H20 may be applied in the following perennial

grasses grown for seed production:

 ̄ Warm-season perennial grasses

Tank Mixes

Prowl H20 may be tank mixed with Outlook® herbicide

or with other herbicides labeled for use in perennial grasses grown for seed. BASF recommends testing Prowl H20

tank mixes on a small portion of the target crop to determine if damage is likely to occur.

Physical incompatibility, reduced weed control, or

crop injury may result from mixing Prowl H20 with

other pesticides, additives, or fertilizers.

Applications of postemergence herbicides may cause crop

injury. Consult your local BASF dealer regarding local tank

mix options. Always perform a mixing test to check the

compatibility of Prowl 1-120 with all potential tank mix partners. Follow all precautions and restrictions on the labels

of all products applied in combination with Prowl

Always follow the most restrictive label.

Restrictions and Limitations

 ̄ DO NOT apply if surface water is present in the field.

 ̄ DO NOT exceed a cumulative total of 4.2 quarts of

Prowl H20 per acre in any one crop season.

 ̄ Some stunting and chlorosis of the perennial

grasses may occur with postemergence

applications.

 ̄ Applications made after the perennial grasses

exceed 6 inches in height may result in poor weed

control due to possible reduced spray coverage to

the soil.

 ̄ DO NOT harvest forage from treated fields of both

warm-season and cool-season perennial grasses until

45 days after application.

 ̄ DO NOT harvest hay from treated fields of both warmseason and cool-season perennial grasses until 60 days

water and germinated and after the soil has been previously sealed over the seed by at least 1 inch of rainfall or

by irrigation (flush). If the soil has not been sealed by rain

or flush, apply when 80 percent of germinated seeds have

a primary root (radicle) or shoot at least

1/2-inch long. If there is insufficient moisture, flushing is

recommended before Prowl H20 application to supply

moisture for root (radicle) initiation and for ~igorous rice

and weed growth.

If applied to soil prior to these conditions, or to cracked

soil, stand reduction or stunting of rice may occur. Under

some conditions, use of gibberellic acid-treated seed~

heaw rainfall after application, or flushing after application

may result in herbicide injury to rice. Rice can overcome

moderate injury with appropriate cultural practices.

Because of the residual activity of Prowl H20, this treatment may be applied if rice is too small to maintain a flood

on the field for weed control However, proper water management practices must be followed for normal rice

growth and actMty of Prowl H20.

Early Postemergence. Apply Prowl H20 as a tank mix

partner. Base applications on weed and crop size guidelines of the tank mix partner. DO NOT apply to fields with

standing water. If necessary, fields may be ~[lushed prior to

treatment to produce vigorous rice and weed growth.

Because soil and weeds must be completely exposed to

spray coverage, no flood water should be on the field at

the time of application. Cloddy soil, standing water (puddles) at the time of application, or cracks in the soil that

form after application may result in reduced weed control

Because of residual activity of Prowl H~O, this treatment

may be applied if rice is too small to maintain a flood on

the field for weed control. However, proper water management practices must be followed for normal rice growth

and activ@ of Prowl H20.

Postemergence (California water-seeded rice only),

Apply Prowl H20 alone or tank mixed with a postemergence herbicide after water-seeded rice has reached the

4-leaf to 6-leaf stage (spike plus 3 to 5 true leaves).

Applications made prior to the 4-leaf rice stage may result

in crop injury.

Water-seeded rice must also be well-footed!pegged

(i.e. standing erect after the flood is removed) prior to

application. DO NOT apply to rice that is leaning over

3O
and/or laying fiat to the ground following flood removal

since this is characteristic of a poorly established root system. Rice roots must be below the ProwP H20

herbicide-treated soil zone. Injury, stunting, and/or stand

reduction can occur if Prowl H20 contacts the rice roots.

Fields must be completely drained and free of standing

water (moist/saturated soil) prior to application. If the soil is

saturated at the time of application, allow the soil surface

to dry prior to restoring the permanent flood. Prowl

requires alternate wetting!drying cycles to be activated.

Weed control will be reduced if the soil surface is not

allowed to dry out prior to restoration of.the permanent

flood. Resume normal water management practices following permanent flood restoration.

Prowl H20 does not control weeds postemergence;

therefore, Prowl H20 must be tank mixed with a postemergence herbicide to control emerged weeds at the

time of application.

Prowl H20 will aid in the control or suppression of the following weeds when used as part of a comprehensive

weed management program:

Barnyardgrass, early and late watergrass (including biotypes resistant to other herbicide modes of action,

e.g. rice mimic), sprangletop, smallflower umbreIla sedge*,

redstem*

*suppression only

In California water-seeded rice, Prowl H20 may be

applied with either aerial or ground application equipment.

For aerial application, apply the recommended rate of

Prowl H20 in 5 gallons to 10 gallons of water per acre. If

applied as a tank mixture with another herbicide, make

sure proper galloeage per acre per label recommendations

(i.e. 10 to 15 with propanil) is used to ensure adequate

coverage. To minimize drift, DO NOT apply during periods

of wind greater than 10 mph, or when wind conditions

favor drifting, or if there is a temperature inversion. It is recommended that a flagman or an automatic mechanical

flagging unit on the aircraft be used to avoid overlapping

and possible crop injury.

For ground equipment, apply the recommended rate of

Prowl H20 in 10 gallons to 20 gallons of water per acre.

If Prowl H20 is applied as a tank mixture with another

herbicide, make sure proper ga!lonage per acre per label

recommendations (i.e. 20 to 30 for propanil) is used to

ensure adequate coverage. Use a prope[ly calibrated lowpressure (20 psi to 40 psi) sprayer equipped with appropriate nozzles to achieve uniform spray distribution and

minimize drift. Keep the bypass line on or near the bottom

of the tank to minimize foaming. Nozzle screens must be

no finer than 50 mesh. DO NOT apply Prowl H20 during

periods of gusty winds or when wind velocity is greater

than 20 mph.

Postemergence Tank Mixtures: To control emerged

weeds at application, Prowl H20 may be tank mixed with

one of the following postemergence herbicides:

Clincher~ herbicide

Grandstand~ herbicide

Granite® SC herbicide

propanil (e.g. Super WHAM!® herbicide)

Regiment® herbicide

Strada® WG herbicide

Whip® 360 herbicide

When using tank mixtures with Prowl H20, always read

the companion product labal(s) and follow all precautions

and restrictions. Always follow the most restrictive label.

Observe all restrictions regarding propanil-restricted zones.

Restrictions and Limitations (for water-seeded rice)

" DO NOT apply Prowl H20 prior to the 4-leaf rice stage

(spike plus 3 true leaves) or to rice that is not wallrooted/pegged. The rice must be standing erect after the
