General Information


Hi-Dep IVM Broadleaf Herbicide consists of the dimethylamine and diethanolamine salts of 2,4-D especially formulated for low volume applications with aerial and ground equipment. For all methods of application, apply the spray solution in properly maintained and calibrated equipment capable of delivering the desired spray volumes. Follow the spray equipment manufacturer’s directions for cleaning, adjusting pressure, and selecting appropriate nozzles. This product must be applied in compliance with the pesticide regulations of the state in which application in made. Check with local authorities regarding regulations which may affect the application of this product. Use a minimum spray volume of 2.0 gallons per acre for ground and aerial applications.

AIRCRAFT SPECIFICATIONS (FIXED WING OR ROTARY WING): Number of nozzles required to obtain desired volume per acre is dependent on swath width and speed of aircraft. Nozzles should be positioned between 135° and 175° from direction of flight for fixed wing. DO NOT APPLY THROUGH BECO-MIST NOZZLE SYSTEMS. See manufacturer’s technical bulletin regarding nozzles and application specifications.

GROUND APPLICATION: Use conventional power spray equipment fitted with a boom, off-center nozzles, or spray gun for broadcast and spot treatments with high volume and low volume foliar applications. Spray equipment may range from an engine driven pump system (e.g. tractor, truck, trailer, all terrain vehicle ATV, wet-blade mowers) to self propelled sprayers. Backpack sprayers, knapsack sprayers, compression sprayers, and hand operated sprayers are appropriate for foliar applications and low volume directed spray applications (basal bark, stem applications).

PRECAUTION FOR PAINTS AND COATINGS OF AUTOMOBILES AND OTHER VEHICLES: Undiluted spray droplets may damage the paint, coating, or finish of vehicles. Vehicles should not be sprayed. If accidental exposure does occur, then the vehicle should be washed before the spray droplets dry.

Susceptible Plants. Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption. Susceptible crops include, but are not limited to, cotton, okra, flowers, grapes (in growing stage), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants.

Other State and Local Requirements. Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-D herbicides. Where states have more stringent regulations, they must be observed.

Equipment. All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers or surrogates.

Additional requirements for ground boom application. Do not apply with a nozzle height greater than 4 feet above the crop canopy.

Additional requirements for aerial applications. 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 height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. This requirement does not apply to forestry or rights-of-way applications. When applications are made with a crosswind, the swath will be displaced downwind. The applicator must compensate for this by adjusting the path of the aircraft upwind.

Limitations, Restrictions, and Exceptions


Applications to noncropland areas are not applicable to treatment of commercial timber or other plants being grown for sale or other commercial use, or for commercial seed production, or for research purposes.

Maximum Number of Applications per year: 1

Broadcast applications to woody plants: Apply to trees and brush when foliage is fully expanded and plants are actively growing. Up to 1.0 gallon of roduct per acre (4.0 lbs. acid equivalent per acre) may be applied in a single application. The maximum noncropland application rate for tree, brush and woody plant control is 1.0 gallon of product per acre per application per site.

Restricted Entry Interval

48 hours
