Ground Applications

To minimize spray drift, apply this product in a total spray volume of 5 or more gallons per acre using spray equipment designed to produce large-droplet, low pressure sprays per ASAE S-572 standard. Refer to the spray equipment manufacturer’s recommendations for detailed information on nozzle types, arrangement, spacing and operating height and pressure. Spot treatments should be applied only with a calibrated boom to prevent over application. 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 fine-droplet spray.

Aerial Application

NOTE: In non-cropland areas (including rights-of-way), this product may be applied aerially only by helicopter. Do NOT apply this product to non-cropland areas using fixed-wing aircraft.

Rangeland, Permanent Pastures and Pine Plantations

This product may be applied to rangeland, permanent pastures and pine plantations using either fixed wing aircraft or helicopter equipment; however, additional drift mitigation measures are required for fixed wing aircraft.

To minimize spray drift, apply this product in a total spray volume of 3 or more gallons 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. Application should be avoided below 2 mph due to variable wind direction and high potential for temperature inversion. Spray drift from aerial application can be minimized by applying a coarse spray as per USDA ARS/ PAASS; by using straight stream nozzles directed straight back; and by using a spray boom no longer than 75% the wing span or 85% of rotor width for the aircraft. For fixed wing aircraft, maximum speed during application is limited to 140 mph and application height above the vegetation canopy should not exceed 10 feet. 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.

† Indicates Suppression Only – Suppression is a reduction in weed competition (i.e., a reduction in 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.

1) Includes biotypes that are herbicide resistant or tolerant.

2) To control these weeds, use the higher rates in the range listed.

3) When controlling kochia, adding a methylated seed oil surfactant (i.e., MSO or ESO) at a rate of 1 to 2 quarts per acre is recommended. Improved control for infestations of larger kochia plants at more advanced growth stages may be achieved by increasing the rate of this product to 1.5 to 2.0 pints per acre OR adding 1 to 2 quarts of 2,4-D and 1 to 2 quarts of methylated seed oil per acre.

Management of Kochia Biotypes

Research indicates many biotypes of kochia may occur within a single field and while kochia biotypes can vary in their susceptibility to this product, in general all biotypes will be suppressed or controlled at the labeled rate of 2/3 pint per acre.

A shift to more tolerant biotypes within a field may occur if this product is applied at rates lower than recommended.

Best Practices for Resistance Management

Extensive populations of dicamba-tolerant kochia have been identified in certain small grain and corn production regions (such as Chouteau, Fergus, Liberty, Toole, and Treasure counties in the state of Montana). For optimal control of dicamba-tolerant kochia in these counties, apply this product at the recommended rate of 2/3 pint per acre.

To minimize selection pressure and preserve the utility of this product for control of dicamba-tolerant kochia biotypes, this product should be rotated with products that do not contain dicamba.

Application Timing

Only weeds that have emerged at the time of application will be controlled so be sure to apply to actively growing weeds. Weed control may be reduced and the risk of crop injury (at all stages of growth) may increase if extreme growing conditions (such as drought or near-freezing temperatures) occur prior to, at, or following application. Control may be decreased if target plant foliage is wet at the time of application. Applications of this product are rain-fast within 1 hour after application.

Effect of Temperature on Herbicidal Activity

The herbicidal activity of this product is influenced by weather conditions.

Optimum herbicidal activity requires active plant growth and temperature between 55ºF to 85ºF. Reduced efficacy will occur when temperatures are below 45ºF or above 85ºF. Weed control and crop tolerance may be reduced if frost occurs before or shortly after application (3 days).

Spray Coverage

Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. For best results (and to minimize spray drift), apply in a spray volume of 5 gallons or more per acre by ground and 3 or more gallons of total spray volume per acre by air. Spray volume should be increased as weed density and vegetative canopy increase in order to obtain equivalent weed control, however, do not exceed 40 gallons per acre total spray volume. Rather than increasing boom pressure, decreased spraying speed or larger nozzle tips should be used to increase spray volume.

Use only nozzle types and spray equipment designed for herbicide application.

To reduce spray drift, be sure to follow the precautions in the section titled Avoiding Injury to Non-Target Plants above.

Spot Treatments

Only apply using a calibrated boom sprayer or with a hand sprayer using the following directions: When using hand-held sprayers for spot applications, be sure to uniformly apply a rate equivalent to a broadcast application. Application rates in the table below are based on an area of 1,000 square feet.

Mix the amount of this product corresponding to the desired broadcast rate in one or more gallons of spray. To calculate the amount of this product required for larger areas, multiply the table value (fluid ounces or ml) by the area to be treated in “thousands” of square feet. An area of 1,000 square feet is approximately 10.5 x 10.5 yards (strides) in size.

For example: If the area to be treated is 3,500 square feet, multiply the table value by 3.5 (calc. 3,500 ÷ 1,000 = 3.5).

Application Rates

In general, the application rates at the lower end of the recommended rate range will be efficacious when applied to susceptible weed species with young, succulent growth. Use the higher rates within the rate range when applying to less sensitive species, perennials, and under conditions where control is more difficult (e.g., when plants are stressed due to drought or extreme temperatures, in dense weed stands and/or the weeds are larger). Higher rates will also be needed to control or suppress weeds in areas where competition from crops is not present (e.g., fallow land).

Refer in the label for tank mix information.

Limitations, Restrictions, and Exceptions


NOTE: There are no grazing restrictions for livestock (including lactating or non-lactating dairy animals).

Application Restrictions

- Do NOT apply more than 2-2/3 pints of this product per acre per year.

- Do NOT apply if injury to legumes cannot be tolerated as this product may injure or kill legumes. Legumes may be less sensitive to herbicide injury after plant growth is mature and seed has set.

- Do NOT harvest grass for hay or silage from treated areas within 7 days of application.

- Only forage grasses, wheat, barley, oats, field corn, sweet corn and grain sorghum may be planted in treated fields within 120 days following application of this product.

Application Timing

Apply this product when weeds are actively growing (but prior to bud stage of weed growth) as a sequential postemergence broadcast treatment or as a single broadcast treatment using ground or aerial application equipment. Use a total spray volume of 5 or more gallons per acre for ground broadcast application or 3 or more gallons per acre by air.

NOTE: Only weeds that have emerged at the time of application will be controlled.
