RANGELAND, ESTABLISHED GRASS PASTURES - ANNUAL WEEDS
Performance of WHITEOUT 2,4-D 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.
Application rates lower than specified will be satisfactory on susceptible annual weeds. For perennial weeds and conditions such as the very dry areas of the western states, where control is difficult, use the higher specified rates. When WHITEOUT 2,4-D 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. Application rates should be 2 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 WHITEOUT 2,4-D specified per acre. For crop uses, do not mix with oil, surfactants, or other adjuvants unless specifically directed. To do so may reduce herbicide’s selectivity and could result in crop damage.
Aerial application must 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. Although WHITEOUT 2,4-D is a low volatile formulation, at temperatures above 90°F vapors may damage susceptible plants nearby.
Product must not be used in greenhouses. Excessive amounts of 2,4-D in the soil may temporarily inhibit seed germination and all plant growth.
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, and then add the remainder of the water. Continue agitation during application until spray tank is empty.
USE IN LIQUID NITROGEN FERTILIZER: WHITEOUT 2,4-D is specially formulated to be combined with liquid nitrogen fertilizer suitable for foliar application on corn, grass, pastures, or small grains in one operation. Use WHITEOUT 2,4-D according to directions on the label for those crops.
Use liquid fertilizer at rates recommended by supplier or extension service specialist. Mix WHITEOUT 2,4-D and fertilizer according to the following instructions:
Add half the recommended amount of liquid fertilizer to the spray tank. Add WHITEOUT 2,4-D while agitating the tank. Add the remainder of the liquid fertilizer while continuing to agitate. Application should be made immediately, maintaining agitation until tank is empty. DO NOT APPLY DURING COLD (NEAR FREEZING) WEATHER. Spray mixture may not be stored.
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.
Spray volume: Apply with calibrated air or ground equipment using sufficient spray volume to provide adequate coverage of target weeds or as otherwise directed in specific use directions. For broadcast application, apply the specified rate of this product in a spray volume of 2 or more gallons per acre by air and 10 or more gallons per acre for ground equipment. Use low-pressure sprays to minimize drift. Where states have regulations, that specify minimum spray volumes, they should be observed. In general, spray volume should be increased as crop canopy, height and weed density increase in order to obtain adequate spray coverage.
Application Rates: Generally, lower rates in specified rate ranges will be satisfactory for more sensitive weeds species, when weeds are small, and when environmental conditions are favorable for rapid growth. Use higher rates in the specified rate range for less sensitive species and under less favorable growing conditions. For crop uses, do not mix with emulsifiable oil or other adjuvants unless specifically directed on the label. Deep-rooted perennial weeds such as Canada thistle and field bindweed and many woody plants usually require repeated applications for effective control.
To prevent misapplication apply spot treatments with a calibrated boom or with hand sprayers using a fixed spray volume per 1,000 sq ft as indicated below.
Hand-Held Sprayers: Hand-held sprayers may be used for spot applications of WHITEOUT 2,4-D.
Care should be taken to apply the spray uniformly and at a rate equivalent to a broadcast application.
Application rates in the table are based on the application rate for an area of 1,000 sq ft. Mix the amount of WHITEOUT 2,4-D (fl oz or ml) corresponding to the desired broadcast rate in 1 to 3 gallons of spray. To calculate the amount of WHITEOUT 2,4-D required for larger areas, multiply the table value (fI oz or ml) by the thousands of sq ft to be treated: An area of 1,000 sq ft is approximately
10.5 x 10.5 yards (strides) in size.
WHERE TO USE
WHITEOUT 2,4-D is used to control broad-leaved weeds in cereal crops, corn, sorghum, weeds and brush in rangeland, pastures, rights-of-way, ornamental turf, grass seed crops, fallow land, forest anagement and similar non-crop uses.
RANGELAND, ESTABLISHED GRASS PASTURES
(Including Perennial Grasslands Not In Agricultural Production
Such As Conservation Reserve Program Acres)
Specific Use Directions
For best results, apply when weeds are small and growing actively before the bud stage. Apply when musk thistles or other biennial species are in the seedling to rosette stage and before flower stalks appear. Refer to the “Weeds Controlled” section for a listing of susceptible weed species and weeds that may be only partially controlled and require repeat applications and/or use of higher listed rates, even under ideal conditions of application.
CRP Acres: For program lands such as CRP, consult program rules to determine whether grass or hay may be used. The more restrictive requirements of the program rules or the label must be followed.
PASTURE & RANGELAND RESTRICTIONS:
- Do not apply more than 4 pints per acre per application.
- Do not apply more than 4 pints per acre per application for spot treatments.
- Do not make more than 2 applications per year.
- Minimum spray interval between applications is 30 days.
- Pre-Harvest Interval for cut forage for hay is 7 days.
- If grass is to be cut for hay, Agricultural Use requirements for the Worker Protection Standard are applicable.
WHITEOUT 2,4-D contains 0.46 pounds a.e. of 2,4-D per pint. When tank mixing with products that contain 2,4-D, do not exceed a combined total of 4.0 pounds of a.e. per acre per year.
