• Incomplete grass control due to herbicide stress: Grasses under stress from previous herbicide applications 

may not be actively growing and susceptible to HELM Nicosuffuron 75. This stress may reduce grass control in 

"rescue" situations. 

• Ear malformation: Applications of HELM Nicosulfuron 75 on com that has 7 to 10 collars (V7 to V10) increases 

the potential for ear malformation (pinching). This risk may be greatly reduced, but not eliminated, by using drop 

nozzles properly adjusted so as to not apply HELM Nicosulfuron 75 into the corn 'Nhorf. 

RATE 

Optimum control of the weeds listed can be achieved with 213 oz. of HELM Nicosulfuron 75. Weeds that exceed the listed 

weed sizes by up to 50% may be partially controlled with rates between 2/3 and 1 1/3 oz. of HELM Nicosulfuron 75 per 

acre. 

HELM Nicosulfuron 75 may be applied at 1/3 - 2/3 oz. for limited control of certain small grass weeds. See Table 2, under 

the section ADDITIONAL RECOMMENDATiONS for detaifs. 

As weeds mature, their sensitivity to HELM NICOSULFURON 75 decreases. As grassy weeds become mature (more 

than 3 tillers), they may not reach the size listed below, due to drought or other environmental factors. Grassy weeds that 

are maturing rapidly should be treated before they reach the stages fisted below. 

When applied as directed, HELM NICoSULFURON 75 wirr control the follOwing weeds:

HELM NICOSULFURON 75 may be broadcast or applied with drop nozzles to popcorn or field corn grown for seed that is 

less than 20" tall (free-standing) or that exhibits up to and including 5 leaf-collars (V5), whichever is most restrictive. Do not 

apply to corn that is tal/er than 20" or that exhibits more than 5 leaf-collars (V5), whichever is more restrictive. 

Many seed companies have tested seed com 'rnbreds or yellow popcorn hybrids for sensitivity to HELM N1COSULFURON 75 

and have reported excellent safety. Do not apply HELM NICOSULFURON 75 to any white popcorn inbred, or white 

popcorn hybrid unless specifically approved by the seed company. This includes 'White Dynamite" pOpCOrn. 

HELM NICOSULFURON 75 may be appfied to certain sweet com hybrids grown for fresh markets or under contract for 

processing. Applications of HELM NICOSULFURON 75 may be applied broadcast or with drop nozzles (post~directed) on 

sweet com up to t2 inches tall or up to and including 5 leaf-col/ars (V5). For sweet corn t2- t8 inches tall, apply only with 

drop nozzles. Do not apply to sweet com taller than t8 inches or those which exhibit 6 or more leaf~collars (V6), and make 

only one application of HELM NICOSULFURON 75 per year. 

SWeet com hybrid sensitivity to HELM N1COSULFURON 75 is highly variable, and not all hybrids have been tested for crop 

tolerance. 

Not alJ seed corn inbreds, popcorn, or sweet corn hybrids have been tested, nor does Sharda USA have access to all 

seed company data. Consequently, Sharda USA is not responsible for any crop injury arising from the use of HELM 

Nicosulfuron 75 on field com grown for seed, popcorn, or sweet com. When tank mixing, check the tank mix partner label 

for tolerances and instructions for use. 

See SOIL INSECTICIDE INTERACTION INFORMATION regarding the use of HELM Nicosulfuron 75 on popcorn, sweet 

corn or field corn grown for seed that has been previously treated with a soil insecticide. 

SPRAY ADJUVANTS 

Applications of HELM Nicosulfuron 75 must include either a crop oil concentrate or a non ionic surfactant. In addition, an 

ammonium nitrOgen fertilizer must be used unless specifically prohibited by tank mix partner labeling. Crop oil concentrate 

plus ammonium nitrogen fertilizer is the preferred adjuvant system for activity on difficult to control species such as woolly 

cupgrass, quackgrass, sandbur and wirestern muhly. If another herbicide is tank mixed with HELM Nicosulfuron 75, select 

adjuvants authorized for use with both products. Products must contain only EPA~exempt ingredients (40 CFR 1001). 

Crop Oil Concentrate (COC) - Petroleum or Modified Seed Oil (MSOJ 

• Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions. 

• MSO adjuvants may be used at 0.5% v/v (0.5 gallons per toO gallons spray solution) if specifically noted on adjuvant 

product labeling. 

• Oil adjuvants must contain at least 80% high quality, petroleum (mineraQ or modified vegetable seed oil with at 

least t5% surfactant emulsifiers. 

Nonionic Surfactant (NIS) 

• Apply at 0.25% v/v (1 quart per 100 gallons spray solution) or 0.5% under arid conditions. 

• Surfactant products must contain at least 60% nonionic surfactant with a hydrophllicfJipophllic balance (HLB) 

greater than 12.

• Use 2 quarts/acre of a high~quality urea ammonium nitrate (UAN), such as 28%N or 32%N, or 2 pounds/acre of a 

spray~grade ammonium sulfate (AMS). Use 4 quarts/acre UAN or 4 pounds/acre AMS under arid conditions. 

• Do not use liquid nitrogen fertilizer as the total carrier solution. 

Special Adjuvant Types 

• Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or 

ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions. 

MIXING INSTRUCTIONS 

1. Fill the tank 1/4 to 1/3 full of water. 

2. While agitating, add the required amount of HELM Nicosulfuron 75. 

3.Continue agitation until HELM Nicosulfuron 75 is fully dispersed, at least 5 minutes. 

4.0nce HELM Nicosulfuron 75 is fully dispersed, maintain agitation and continue filling tank with water. Thoroughly 

mix HELM Nicosulfuron 75 with water before adding any other material. 

S.As the tank is filling, add the required spray adjuvants (crop oil concentrate, nonionic surfactant, or ammonium 

nitrogen fertilizer). 

6.lf the mixture is not continuously ag'rtated, settling will occur. If settling occurs, thoroughly re-agitate before using. 

7.Apply HELM Nicosulfuron 75 spray mixture within 24 hours of mixing to avoid product degradation. 

S.lf HELM N'lcosulfuron 75 and a tank mix partner are to be applied in multiple loads, pre-slurry HELM Nicosulfuron 75 

in clean water prior to adding to the tank. This will prevent the tank mix partner from interfering with the dissolution of 

HELM Nicosulfuron 75. 

SEQUENTIAL APPLICATIONS FOLLOWING REDUCED RATES OF PREEMERGENCE HERBICIDES 

HELM Nicosulfuron 75 may be used as a sequential application in a planned postemergence weed control program in corn 

following a reduced rate of a preemergence herbicide. 

Apply a reduced rate of a preemergence grass herbic'lde prior to com emergence and then follow with a postemergence 

application of HELM Nicosulfuron 75. Apply products such as "Cinch~®, "Cinch"® ATZ, "Balance" PRO, "Axiom", "Dual" H 

Magnum, "Surpass", "Outlook" and "Harness" Xtra at as low as 1/4 to 1/2 of the full labeled use rate and follow with a 

sequential postemergence application of HELM Nicosulfuron 75. Refer to the preemergence grass herbicide label for use 

restrictions, application information, rotational crap guidelines, and cautionary statements prior to applying HELM 

Nicosulfuron 75. 

Do not apply HELM Nicosulfuron 75 to com that exhibits herbicide injUry from previous applications made to the current or 

preceding crop. 

TANK MIX APPLICA TlONS 

For Additional Control of Broad/eat Weeds 

Nicosulfuron WDG may be tank mixed with many herbicides registered for postemergence application in com for additional 

control of broadleaf weeds. See the tank mix partner label for weeds controlled, precautions, use restrictions, adjuvant and 

crop rotation information. The most restlictive language on either label shall apply. 

In addition to the tank mixtures noted above, HELM Nicosulfuron 75 may be tank mixed with the rates of products listed 

below for improved control of many broadleaf weeds, including cocklebur, dandelion, Eastern black nightshade,

Page 10 of 17 

HELM Nicosulfuron 75 may be tank mixed with full or reduced rates of preemergence grass herbicides labeled for early 

postemergence application to field com (such as Cinch®, Cinch® ATZ, "PrO'NI", "Surpass" EC, "Duaf' II Magnum, or "Outlook") 

for residual activity on later-emerging flushes of grass. Application must be made before the grass emerges and before 

other grass weeds on the HELM Nicosulfuron 75 label exceed their labeled sizes. 

The use of non ionic surfactant is recommended in place of crop oil concentrate for tank mixtures with preemergence 

grass herbicides where applications are made early postemergence to small grass weeds. See SPRAY ADJUVANTS for 

adjuvant rate recommendations. 

When tank mixing HELM Nicosulfuron 75 with EC formulated preemergence grass herbicides such as Cinch®, "Prow!", or 

"Duar' II Magnum, do notadd "Canisto" herbicide to the tank mixture. VVhen other formulations of preemergence grass herbicides are 

tank mixed with HELM Nicosulfuron 75 + "Caniste" (such as Cinch® ATZ oruBicep II Magnum''), Umit preemergence herbiCide rates to 

2J3 times full rates, always add nonlonic surfactant in place of crop oil concentrate, and, Umit broadleafweed sizes to less than or equal to 

4" tall. 

When tank mixing HELM Nicosulfuron 75 with "Lumax" oruLexar" herbiddes, limit "Lumax" rates to no more tilan 2 pints and uLexar" 

rates to no more than 2 1/3 pntslacre. /W./ays add nonionic surfactant in place of crop oil concentrate, omit adjuvants containing 

ammonium nitrogen fef1iT1zer, and limit applications to cern up to 5" tall. 

Tank mixes of HELM Nicosulfuron 75 and preemergence grass herbicides must be broadcast apprled postemergence to field com 

before the crop exceeds the heights listed on the preemergence grass herbicide label. Refer to WHEN TO APPLY~ 

POSTEMERGENCE and the preemergence grass herbicide label for complete postemergence apprrcation information, rates, 

and restrictions. 

Tank Mixtures with Insecticides 

HELM Nicosutfuron 75 may be tank mixed with pyrettlroid or carbamate insecticides. See Soil Insecticide Interaction section for 

information on use of HELM Nicosulfuron 75® following soil insecticides application. 

Other Tank Mixtures 

Otherthan the exceptions noted, and in addition to tile tank mix partners and rates indicated above, Nicosutfuront 75 WDG may be 

tank mixed orfol1owed with sequential applications of other products registered for use in field com. Appncations of full or reduced 

rates of other products registered for use in com provided: 

• The tank mix product is labeled for the same timing, method of application, adjuvants, and use restrictions as HELM Nicosulfuron 

75. 

• The tank mixture is not specifically prohibited on tile label of the tank mix product 

• The tank mix combination is compatible as determined by a 'jar test:' described in the TANK MIX COMPATIBILITY 

TESTING section below. 

Weed control and crop response with tank mixtures not specifically recommended in this label are the responsibility of the 

user and manufacturer of the tank mix product 

Tank Mixing Precautions 

A com plant's predisposition to develop fused tissue emerging from the whorl (rattail) after the V~11 stage may increase 

when a product containing dicamba (i.e. "Clarity", "Marksman") is applied to small corn under early stressful conditions. 

Be aware of this when applying tank mixes witil dicamba to small corn (V-3 stage or smaller) under stressful conditions. 

See ENVIRONMENTAL CONDITIONS for a description of these stressful conditions. 

To avoid crop injury or antagonism, apply tile products indicated below at least seven days before or three days after the 

application of HELM Nicosulfuron 75. 

• Do not tank mix HELM Nicosulfuron 75 with "Basagran U and "Laddock" or severe crop injury may occur. 

• Do not tank mix HELM Nicosulfuron 75 with 2,4~D~ containing products as severe grass control 

antagonism may occur. 

• Do not tank mix HELM Nicosulfuron 75 with foliar-applied organophosphate insecticides such as 

~Lorsban", malathion, parathion, etc., as severe crop injury may occur.

Page 11 of17 

Do not exceed labeled application rates. Do not tank mix HELM Nicosulfuron 75 with other products that contain the same 

active ingredient as HELM Nicosulfuron 75 (nicosulfuron) unless the label of either tank mix partner specifies the 

maximum rate that may be used. 

TANK MIX COMPATIBIUTY TESTING 

Perform a jar test prior to tank mixing to ensure compatibility of HELM Nicosulfuron 75 and other pesticides. Use a clear glass 

quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the mixture several 

times and observe the mixture for approximately 1/2 hour. If the mixture balls-up, forms flakes, sludges, gels, oily films or 

layers, or other precipitates, it is not compatible and the tank mix combination should not be used. 

SEQUENTIAL HELM NICOSULFURON 75 APPLICATIONS 

Annual grasses may have more than one flush of emerging seedlings. Also, regrowth of treated annual grasses may 

occur due to adverse environmental conditions following appncation. Perennial grasses may regrow from underground 

stems or roots, depending upon environmental conditions. To control grasses under these conditions, a sequential 

application of HELM Nicosulfuron 75 may be necessary. The combined dosage of the sequential applications cannot 

exceed 1 1/3 ounces per acre of HELM Nicosulfuron 75. 

CULTIVATION 

A timely cultivation may be necessary to control suppressed weeds, or we.eds that emerge after an application of 

HELM Nicosulfuron 75. 

Optimum timing for CUltivation is 7-14 days after HELM Nicosulfuron 75 application or upon seeing the establishment of 

new weeds. 

ENVIRONMENTAL CONDITIONS AND BIOLOGiCAL ACTIVITY 

HELM Nicosulfuron 75 provides best results when applied to young, actively growing weeds. Applications made during 

warm, moist conditions (70°F or more) and adequate soil moisture both before and after application maximizes 

performance. 

The degree and duration of control depend on spray coverage, weed spectrum, weed size, growing conditions before and 

after treatment, soil moisture, and adjuvant selection. 

HELM Nicosulfuron 75 is rainfast in 4 hours. 

Treating weeds that exceed maximum label height or that are under stress may result in incomplete control. Poor weed 

control or crop injury may result from applications made to plants under stress from: 

• abnormally hot or cold weather 

• environmental conditions such as drought, water-saturated soils, hail damage, or frost 

• disease, insect, or nematode injury 

• prior herbiCide, or carryover from a previous year's herbicide application 

Severe stress from conditions preceding or immediately fonowing application may also result in crop injury or poor 

weed control. Stress affects all weeds, but especially weeds such as woolly cupgrass, green and yellow foxtail, and wild 

proso millet. 

If the com or grass weeds are under stress, delay application until stress passes and both weeds and corn resume active 

growth. 

HELM Nicosulfuron 75 rapidly inhibits the growth of susceptible weeds, reducing weed competition within as nttle as 6 hours 

after application. Susceptible plants are controlled in 7-21 days. 

SOIL INSECTICIDE INTERACnON INFORMA nON 

Before using HELM Nicosulfuron 75, ensure that it is compatible with any insecticides previously applied to the Corn crop. 

HELM Nicosulfuron 75 may interact with certain insecticides previously applied to the crop. Crop response varies with 

15

whorl. This is most likelY to occur when a nozzle is positioned directly above the row. 

• Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury. 

Band Application 

HELM Nicosulfuron 75 

23Ju!y2007 

Page 14 of 17 

For band applications, use proportionately less spray mixture, and carefully calibrate the band applicator to not 

exceed the labeled rate. Carefully follow the manufacturer's instructions for nozzle type (flat fans), orientation, distance 

of nozzles from the crop and weeds, spray volumes, calibration and spray pressure. 

AERIAL APPLICATION 

In New York and California aerial application is not permitted. 

Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a 

minimum of 3 GPA. 

Do not apply during a temperature inversion, when winds are gusty, or when conditions favor poor coverage and/or 

off-target spray movement. 

SPRAYER PREPARATION/CLEANUP 

It is important that spray equipment is clean and free of previous pesticide deposits before using HELM Nicosulfuron 75 and 

then properly cleaned out fol/owing application. Clean all application equipment before applying HELM Nicosulfuron 75. 

Follow the cleanup procedures specified on the label of the product previously sprayed. If no cleanup procedure is provided, 

use the procedure that follows. Immediately following applications of HELM Nicosulfuron 75, thoroughly clean all mixing and 

spray equipment to avoid subsequent crop injury. 

Note: 

• When cleaning spray eqUipment before applying HELM N"icosulfuron 75, read and follow label directions for proper rinsate 

disposal of the product previously sprayed. 

• Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits. 

• When spraying or mixing equipment will be used over an extended period to apply multiple loads of HELM Nicosulfuron 

75, partially fill the tank with fresh water at the end of each day of spraying, flush the boom and hoses, and al/ow to sit 

overnight 

Cleanup Procedure 

I. Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with clean water for 

a minimum of 5 min. 

2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3% active) for every 

100 gallons of water. Finish filling the tank with water, then flush the cleaning solution through the hoses, boom, 

and nozzles. Add more water to completely fill the tank and allow to agitate/recirculate for at least 15 min. Again, 

flush the hoses, boom, and nozzles with the cleaning solution, then drain the tank. 

3. Repeat Step 2. 

4. Remove the nozzles and screens and clean separately in a bucket containing the cleaning agent and water. 

5. Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the hoses 

and boom. 

* Equivalent amounts ofan alternate strength ammonia solution may be used. 

SPRAY DRIFT MANAGEMENT 

The interaction of many equipment and weather-related factors determines the potential for spray drift. The 

applicator is responsible for considering all these factors when making application decisions. 

AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR.

SHIELDED SPRAYERS 

HELM Nicosulfuron 75 

23JulyZ007 

Page 16 of 17 

Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the 

applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product. 

INTEGRATED PEST MANAGEMENT 

This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, 

cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field 

scouting or other detection methods, correct target pest identification, population monitoring, and treating when 

target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, 

professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for 

treating specific pesVcrop systems in your area. 

RESISTANCE 

When herbicides that affect the same biological site of action are used repeatedly over several years to control the 

same weed species in the same field, naturally~occurring resistant biotypes may survive a correctly applied herbicide 

treatment, propagate, and become dominant in that field. Adequate control of these resistant weed biotypes cannot be 

expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product 

affecting a different site of action. 

To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide 

resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as 

using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a 

different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant b·lotypes. 

It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the 

spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate 

state agricultural extension service representative for specific alternative cultural practices or herbicide 

recommendations available in your area. 

IMPORTANT PRECAUTIONS 

Injury to or loss of desirable vegetation may result from failUre to obServe the following: 

• Do not apply HELM Nicosulfuron 75 or drain or flush application equipment on or near desirable trees or other plants, or 

on areaS where their roots may extend, or in locations where the chemical may be washed or moved into contact with 

their roots. 

• Do not use on lawns, walks, driveways, tennis courts, or similar areas. 

• Prevent drtft of spray to desirable plants. 

• Do not contaminate any body of water. 

• Thoroughly clean application equipment immediately after use. (See the Sprayer Cleanup section of this label for 

instructions). 

• Do not graze or feed forage, hay, or straw from treated areas to livestock within 30 days of HELM Nicosulfuron 75 

application.
