Weed-Rhap A-6D Herbicide 2,4-D Amine
Performance of this product may be affected by local conditions, crop varieties, and application method. User should consult local extension service, agricultural experiment, or university weed specialists, and state regulatory agencies for recommendations in your area.
Best results are obtained when product is applied to young succulent weeds that are actively growing. Use the lower specified application rates on susceptible annual weeds. For perennial weeds and conditions such as the very dry areas of the western states, where control is difficult, the higher specified application rates should be used. When product is used for weed control in crops, the growth stage of the crop must be considered.
Some plants and weeds, especially woody varieties, are difficult to control and may require repeat applications. Apply at 1 to 5 gallons of total spray by air or 5 to 25 gallons by ground equipment unless otherwise directed. In either case, use the same amount of 2,4-D listed per acre. For crop uses, do not mix with oil, surfactants, or other adjuvants unless specifically specified on label. To do so may reduce herbicides selectivity and could result in crop damage.
Aerial application should be used only when there is no danger of drift to susceptible crops. Many states have regulations concerning aerial application of 2,4-D formulations. Consult local regulatory authorities before making applications. Weed Rhap A-6D contains the Dimethylamine salt of 2,4-D, one of the least volatile forms of 2,4-D. Because coarse sprays are less likely to drift than fine, do not use equipment (such as hollow cone small orifice nozzles) or conditions (such as high pressure) that produce such sprays. Product should not be allowed to come into contact with desirable, susceptible plants such as beans, cotton, fruit trees, grapes, legumes, ornamentals, peas, tomatoes, and other vegetables. Product should not be used in greenhouses. Excessive amounts of this product in the soil may temporarily inhibit seed germination and all plant growth. Users should note that herbicide treatment of public water requires a permit from appropriate state agencies in most states. Your state Conservation Department, or Game and Fish Commission will aid you in securing a permit in your state. If stored below freezing, product should be warmed to at least 40oF and agitated before using. This does not affect the efficacy of the product. Spray equipment used to apply 2,4-D should not be used for any other purpose until thoroughly cleaned with a suitable chemical cleaner.
Spray Preparation: Add the specified amount of product to approximately one-half the volume of water to be used for spraying. Agitate well, then add the remainder of the water. Continue agitation during application until spray tank is empty. Use in Liquid Nitrogen Fertilizer: Product may be combined with liquid nitrogen fertilizer suitable for foliar application on corn, grass, pastures, or small grains in one operation. Use Weed Rhap A-6D according to directions on this label for those crops. Use liquid nitrogen fertilizer at rates recommended by supplier or extension service specialist. Mix the Weed Rhap A-6D and fertilizer according to the following instructions: Fill the spray tank approximately 1/2 full with the liquid nitrogen fertilizer. In a separate container, mix the amount of Weed Rhap A-6D to be used with an equal amount of water. Add Weed Rhap A-6D mixture to the spray tank while agitating. Add the remainder of the liquid fertilizer while continuing to agitate. Apply immediately, maintaining agitation during application until tank is empty. DO NOT APPLY DURING COLD (NEAR FREEZING) WEATHER. Spray mixture must be used immediately and may not be stored.
NOTE: Pre-mixing the Weed Rhap A-6D with an equal amount of water is important.
