Application Procedures

This product can be applied by ground or aerial application. The following provides methods of application for each crop.Aerial Application: Use orifice disks, cores and nozzle types and arrangements that will provide for optimum spray distribution and maximum coverage. Use a minimum spray volume of 5 gallons per acre and a maximum pressure of 20 psi. The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter. Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a heights greater than 10 feet above the crop canopy.When applications are made with a crosswind, the swath will be displaced downwind. The applicator must compensate for this displacement at the downwind edge of the application area by adjusting the path of the aircraft upwind.Do not make applications into temperature inversions.Ground Application: Use a standard herbicide sprayer that provides uniform and accurate application. Equip sprayer with screens no finer than 50 mesh in the nozzle tips and in-line strainers.Select a spray volume and delivery system that will ensure thorough and uniform spray coverage. For optimum spray distribution and thorough coverage, use flat fan nozzles (maximum tip size 8008) with a minimum spray pressure of 20 psi at the nozzle tips. Other nozzle types that produce coarse spray droplets may not provide adequate coverage of the weeds to ensure optimum control. Do not use raindrop nozzles to apply this product because weed control may be reduced. Use a minimum spray volume of 10 gallons per acre for optimum spray coverage. When using higher speed equipment, a maximum speed of 10 miles per hour is suggested if field conditions cause excessive boom movement during application and subsequent poor spray coverage. Ground applications made when dry, dusty field conditions exist may provide reduced weed control in wheel track areas. Do not apply with a nozzle height greater than 4 feet above the crop canopy.

Mixing Instructions

This Product Alone: Fill the spray tank one-half to three-fourths full with clean water. Begin agitation and add the listed amount of this product. Use the lower rates of this product shown under each crop when weeds are young and actively growing. Use the higher rates of this product listed when weeds are larger and not growing rapidly. Add water to the spray tank to the desired level. Maintain sufficient agitation to ensure a uniform spray mixture during application.

This Product in Tank-Mixtures: This product can be applied in tank-mixture with other herbicides registered for use on approved crops. Refer to the specific crop section for application rates and other restrictions. Use the lower rates of this product shown under each crop when weeds are young and actively growing. Use the higher rates of this product listed when weeds are larger and not growing rapidly. To apply this product in mixture with another product, fill the spray tank one-half to three-fourths full with clean water and begin agitation. If tank-mixing with wettable powder, soluble powder, flowable or dry flowable products, add the powder or flowable product first. After the other herbicide is thoroughly mixed with water, add the listed amount of this product and add water to the spray tank to the desired level.

If tank-mixing the other product types, add this product first before adding the other product. Always mix one product in water thoroughly before adding another product or compatibility problems may occur. Never mix two products together without first mixing in water. Maintain sufficient agitation while mixing and during application to ensure a uniform spray mixture. If spray mixture is allowed to remain without agitation for short periods of time, be sure to agitate until uniformly mixed before application.

It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank-mixture.

Compatibility: This product may form an insoluble precipitate in very hard water. If you expect to mix this product with very hard water, test compatibility by mixing a small amount of this product in the proposed dilution rations, shake and observe. A compatibility agent approved for use on growing crops may be tested to reduce precipitation. Whenever hard water is used to dilute this product, spray immediately and do not allow spray mixture to sit overnight.

Follow manufacturer’s instructions for cleaning/ maintaining PPE. If no such instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry.

ENGINEERING CONTROLS

When handlers use closed systems, enclosed cabs or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240(d)(4-6)], the handler PPE requirements may be reduced or modified as specified in the WPS.

Pilots must use an enclosed cockpit in a manner that is consistent with the WPS for agricultural pesticides [40 CFR 170.240(d)(6)]. Pilots must wear the PPE required on this labeling for applicators.

Important: When reduced PPE is worn because a closed system is being used, handlers must be provided all PPE specified above for applicators and other handlers and have such PPE immediately available for use in an emergency such as a spill or equipment breakdown.

Environmental Hazard

This chemical is toxic to fish. Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Drift and runoff from treated areas may be hazardous to aquatic organisms in neighboring issues. Do not contaminate water when disposing of equipment washwaters or rinsate. Do not contaminate water intended for irrigation or domestic purposes. Do not apply when weather conditions favor drift from target area.

Groundwater Advisory;

Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-DB have been associated with mixing/loading and disposal sites. Precaution must be exercised when handling 2,4-DB pesticides at such sites to prevent contamination of groundwater supplies. Use of closed systems for mixing or transferring this pesticide will reduce the probability of spills. Placement of the mixing/loading equipment on an impervious pad to contain spill will help prevent groundwater contamination.This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Application around a cistern or well may result in contamination of drinking water or groundwater.

Restrictions
  • Do not apply this product through any type of irrigation system.
  • Do not use in or near a greenhouse.
  • Do not feed/graze Soybean forage or harvest hay for 60 days following any 2,4-DB application.
  • Do not apply this product directly to or otherwise permit it to come in contact with Cotton, Flowers, Fruit trees, Grapes, Okra, Tomatoes, Vegetables or other desirable crop or ornamental plants. Do not permit spray mist to drift onto susceptible plants because very small quantities of 2,4-DB can cause severe injury during the growing or dormant periods. Use coarse sprays to minimize drift. Do not apply with nozzles that produce fine spray droplets.
Precautions

Mixing and Loading: Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-DB have been associated with mixing/loading and disposal sites. Precaution must be exercised when handling 2,4-DB pesticides at such sites to prevent contamination of groundwater supplies. Use of closed systems for mixing or transferring this pesticide will reduce the probability of spills. Placement of the mixing/loading equipment directly on an impervious pad to contain spills will help prevent groundwater contamination.

Drift from ground application may be reduced by:

(1) Keeping the spray boom as near to the crop as possible in order to obtain complete coverage;

(2) By applying 10 gallons or more of spray per acre;

(3) By using no more than 20 pounds of pressure at the nozzle tips; and

(4) By not spraying when wind exceeds 5 miles per hour. Drift from aerial application may be reduced by:

  • Applying as near to the target as possible to obtain adequate coverage;
  • By applying 5 or more gallons of spray per acre;
  • By using 20 pounds pressure or less at the nozzle tips;
  • By using nozzles which produce a coarse spray pattern; and

(5) By spraying when there is no possibility for a temperature inversion at time of spraying. Applications by aircraft, ground rig and hand sprayers must be carried out only when there is no hazard from spray drift.
