Product Information

Use QuelexTM herbicide as a postemergence herbicide for the control of annual broadleaf weeds such as

common lambsquarters, redroot pigweed, cleavers, henbit, wild buckwheat and mustards in wheat

(including spring, winter and durum), barley, and triticale not underseeded with legumes.

Quelex rapidly stops growth of susceptible weeds. However, typical symptoms (discoloration) of dying

weeds may not be noticeable for 1 to 2 weeks after application, depending upon growing conditions and

weed susceptibility. Degree of control and duration of effect are dependent upon weed sensitivity, weed

size, crop competition, growing conditions at and following treatment, and spray coverage.

Use Restrictions

• Chemigation: Do not apply this product through any type of irrigation system.

• Do not apply Quelex directly to, or otherwise permit it to come into direct contact with, susceptible

crops or desirable plants including alfalfa, edible beans, canola, flowers and ornamentals, lentils,

lettuce, peas, potatoes, radishes, soybeans, sugar beets, sunflowers, tomatoes, or tobacco. Do

not permit spray mists containing Quelex to drift onto such plants.

• Do not apply to crops underseeded with legumes.

• Do not apply more than 0.75 ounces of Quelex per acre per growing season.
Q8J / Quelex / MSTR Prop Sec 3 / 04-06-16 Page 9

• Do not apply halauxifen methyl to more than two growing seasons per year.

Herbicide Resistance Management

Quelex contains both an ALS mode of action Group 2 herbicide and auxin mode of action Group 4

herbicide. Appropriate resistance management strategies should be followed.

To delay herbicide resistance:

• For best resistance management stewardship, it is recommended not to use Quelex in successive

seasons.

• Where possible, rotate the use of Quelex with different herbicide groups that control the same weeds in

a field.

• Base herbicide use on an IPM program that includes scouting, historical information related to herbicide

use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other

chemical control practices.

• Monitor treated weed populations for resistance development.

• Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment

and planting clean seed.

• Contact your local extension specialist or certified crop advisers for any additional pesticide resistance

management and/or integrated weed management recommendations for specific crops and weed

biotypes.

Crop Rotation Intervals

The following rotational crops may be planted at the indicated interval following application of Quelex. For

best results conduct a field bioassay prior to planting any broadleaf crops not listed. Do not plant unlisted

crops prior to 15 months prior to application.

(1) Minimum number of months that must pass before planting other crops after application of Quelex.

Ground Applications: To minimize spray drift, apply Quelex in a total spray volume of 8 gallons or more

per acre using spray equipment designed to produce large-droplet, low pressure sprays. Refer to the

spray equipment manufacturer's recommendations for detailed information on nozzle types, arrangement,

spacing and operating height and pressure. To prevent over application when making spot treatments

apply with a calibrated boom. Operate equipment at spray pressures no greater than is necessary to

produce a uniform spray pattern. Operate the spray boom no higher than is necessary to produce a

uniformly overlapping pattern between spray nozzles.

• Do not apply with hollow cone-type insecticide nozzles or other nozzles that produce a finedroplet spray.

• Apply Quelex with a nozzle class that ensures a medium or coarser spray (Spray droplet size with

VMD > 340 microns according to ASABE S572.1).
Q8J / Quelex / MSTR Prop Sec 3 / 04-06-16 Page 10

Aerial Application: To minimize spray drift, apply Quelex in a total spray volume of 5 gallons or more

per acre. Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including

droplet size and equipment type, determine drift potential at any given speed. Spray pattern and droplet

size distribution can be evaluated by applying sprays containing a water-soluble dye marker or

appropriate drift control agents over a paper tape (adding machine tape). Mechanical flagging devices

may also be used. Spray drift from aerial application can be minimized by applying a coarse spray at

spray boom pressure no greater than 30 psi; by using straight-stream nozzles directed straight back; and

by using a spray boom that does not exceed 75% of wingspan or 90% of rotor diameter.

• Apply Quelex with a nozzle class that ensures medium or coarser spray (Spray droplet size with

VMD > 340 microns according to ASABE S572.1).

• Do not apply in wind speeds greater than 15 mph.

• Do not apply below 2 mph due to variable wind direction and high potential for temperature

inversion.

Avoid Injurious Spray Drift

This product can affect broadleaf plants directly through foliage and indirectly by root uptake from treated

soil. Do not apply Quelex directly to, or allow spray drift to come into contact with, broadleaf crops,

including alfalfa, canola, beans, cotton, flowers, grapes, lettuce, lentils, mustard, peas, potatoes,

radishes, soybeans, sugar beets, sunflowers, tobacco, tomatoes, vegetables, or other desirable broadleaf

crops or ornamental plants or soil where sensitive crops will be planted the same season. (See Crop

Rotation Intervals section.)

Make applications only when there is little or no hazard from spray drift. Very small quantities of spray,

which may not be visible, may seriously injure crops, whether dormant or actively growing. When

applying Quelex, use low pressure equipment capable of producing sprays of uniform droplet size with a

minimum of fine spray droplets. Under adverse weather conditions, fine spray droplets that do not settle

rapidly onto target vegetation may be carried a considerable distance from the treatment area. A drift

control or spray thickening agent may be used with this product to improve spray deposition and minimize

the potential for spray drift. If used, follow all use directions and precautions on the product label.

Spray Drift Management

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

equipment and weather-related factors determine the potential for spray drift. The applicator and the

grower are responsible for considering all these factors when making decisions.

Wind: Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including

droplet size and equipment type, determine drift 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.

Drift potential is lowest when wind speeds are 10 mph or less. However, many factors, including droplet

size, pressure, and quipment type determine drift potential at any given wind speed. Note: Local terrain

can influence wind patterns.

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 should not occur during a local, low level temperature inversion

because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small

suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions

due to the light variable winds common during inversions. Temperature 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
Q8J / Quelex / MSTR Prop Sec 3 / 04-06-16 Page 11

of the smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves

laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that

moves upward and rapidly dissipates indicates good vertical air mixing.

Sensitive Areas: Only apply the pesticide when the potential for drift to adjacent sensitive areas (e.g.,

residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops)

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

Other State and Local Requirements

Applicators must follow all state and local pesticide drift requirements regarding application of herbicides.

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 Aerial

Drift Reduction Advisory. (This information is advisory in nature and does not supersede mandatory label

requirements.)

Aerial Drift Reduction Advisory

The following drift management requirements must be followed to avoid off-target drift movement from

aerial applications:

• The distance of the outer most operating nozzles on the boom must not exceed 75% of wingspan or

90% of rotor diameter.

• Nozzles must always point backward parallel with the air stream and never be pointed downwards more

than 45 degrees.

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 sufficient 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 higher

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 higher 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 the recommended practice. Significant deflection from

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 low-drift nozzles. Solid stream nozzles

oriented straight back produce the largest droplets and the lowest drift.

Boom Length: For some use patterns, reducing the effective boom length to less than 75% of the

wingspan or 90% of rotor length may further reduce drift without reducing swath width.

Application Height: 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. Making applications at the lowest

height that is safe reduces exposure of droplets to evaporation and wind.

Swath Adjustment: When applications are made with a crosswind, the swath will be displaced

downwind. Therefore, on the up and downwind edges of the field, the applicator must compensate for
Q8J / Quelex / MSTR Prop Sec 3 / 04-06-16 Page 12

this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should

increase with increasing drift potential (higher wind, smaller drops, etc.).

5. Continue agitation while filling the spray tank to the required volume.

6. To ensure a uniform spray mixture, continuous agitation is required during application. If product is

allowed to settle, thoroughly agitate to resuspend the mixture before spraying. Apply mixture

immediately after it is prepared.

Clean-Out Procedures for Spray Equipment

1. Drain any remaining spray mixture from the application equipment, then wash out tank, boom, and

hoses with clear water. Drain again.

2. Hose down the interior surfaces of the tank while filling the tank 1/2 full of water.

3. Add commercial tank cleaner, such as household ammonia, at a rate of 1 gallon per 100 gallons of

water. Recirculate for 10 – 20 minutes and spray out the mixture through the boom.

4. Remove all spray nozzles and screens and clean separately.

5. If spray equipment will be used for pesticide application to crops sensitive to Quelex, repeat steps 1

through 3. Additional steps may also be required to remove all traces of Quelex including replacing

hoses or other fittings that may contain adsorbed actives.

6. Thoroughly clean exterior surfaces of spray equipment.

Note: Rinsate may be disposed of on site according to label use directions or at an approved waste

disposal facility. Reduced results may occur if water containing soil is used, such as visibly muddy water

or water from ponds and ditches that is not clear.

2Suppression is expressed as a reduction in weed competition (reduced population or vigor) as compared

to untreated areas. The degree of weed control and duration of effect may vary with weed size, density,

application rate, coverage, and growing conditions before, during and after treatment.

Product Application Instructions

Application Timing

Apply Quelex in the spring or fall early postemergence to the main flush of actively growing weeds in the

2 to 4 leaf stage or less than 4 inches tall. Extreme growing conditions such as drought or near freezing

temperatures prior to, at, or following time of application may reduce weed control and increase the risk of

crop injury at all stages of growth. Only weeds that have emerged at the time of application will be

controlled. If foliage is wet at the time of application, control may be decreased. Applications of Quelex

are rainfast within 4 hours after application.

Spray Coverage

Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. Do not broadcast

apply in less than 5 gallons of total spray volume per acre. For best results and to minimize spray drift,

apply in a spray volume of 10 gallons or more per acre. As vegetative canopy and weed density

increase, increase spray volume to obtain equivalent weed control. Use only nozzle types and spray

equipment designed for herbicide application. To reduce spray drift, follow precautions under Avoid

Injurious Spray Drift.

Adjuvants

When Quelex is applied alone, use a non-ionic surfactant at 1.6 to 4 pints per 100 gallons of spray

solution (0.2 – 0.5% v/v), or a Crop Oil Concentrate (COC) or Methylated Seed Oil (MSO) at 4 to 8 pints

per 100 gallons (0.5 – 1.0% v/v). When an adjuvant is to be used with this product, Dow AgroSciences

recommends the use of a Chemical Producers and Distributors Association certified adjuvant.

Application in Fluid Fertilizer

Quelex may be applied in spray solutions containing liquid nitrogen fertilizer. Run a tank mix compatibility

test before mixing Quelex in fertilizer solution. Mix and disperse Quelex granules in clean water as a preslurry before adding to liquid fertilizer solution. When Quelex is applied in spray solutions containing

liquid nitrogen fertilizer, use a non-ionic surfactant at a maximum of 0.25% v/v instead of crop oil

concentrate or methylated seed oil. Temporary crop injury may result when liquid nitrogen fertilizer is
Q8J / Quelex / MSTR Prop Sec 3 / 04-06-16 Page 14

used as the spray carrier. Foliar applied liquid nitrogen fertilizer may cause foliar leaf burn, yellowing or

reduced growth due to the activity of the liquid fertilizer on the crop.

Postemergence Application

Wheat (Including spring, winter and durum), Barley and Triticale

Apply 0.75 ounces of Quelex per acre to actively growing wheat (including spring, winter and durum),

barley and triticale, from the 2-leaf to flag leaf emergence stage (Zadoks scale 39). The treatment may be

applied in the autumn or spring in winter wheat. For best results apply when weeds are actively growing

in the 2 to 4 leaf stage or less than 4 inches tall. Only weeds emerged at the time of treatment will be

controlled. Best results are obtained from applications made to seedling weeds.

Warm, moist growing conditions promote active weed growth and enhance the activity of Quelex by

allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought

stress may not be adequately controlled or suppressed and re-growth may occur. For best results,

ensure thorough spray coverage of target weeds.

Quelex Use Restrictions:

• Do not apply more than 0.75 ounces of Quelex per acre per growing season.

• Do not apply haulauxifen methyl to more than two growing seasons per year.

• Preharvest Interval: Do not apply within 60 days of crop harvest.

• Do not apply closer than 21 days before cutting of hay.

• Do not allow livestock to graze on treated crops for 7 days following application.

• Do not compost any plant material from treated area.
