RANGELAND, ESTABLISHED GRASS PASTURES - ANNUAL BROADLEAF WEEDS
Performance of SOLVE 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 recommended 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, the higher recommended rates should be used. When SOLVE 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 SOLVE 2,4-D recommended per acre. For crop uses, do not mix with oil, surfactants, or other adjuvants unless specifically recommended. To do so may reduce herbicide’s 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. Although SOLVE 2,4-D is a low volatile formulation, at temperatures above 90°F vapors may damage susceptible plants nearby.
Product should not be used in greenhouses. Excessive amounts of 2,4-D 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, warm the product to 40°F and agitate before using. This does not affect the efficiency 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 recommended 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: SOLVE 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 SOLVE 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 SOLVE 2,4-D and fertilizer according to the following instructions:
Fill the spray tank approximately 1/2 full with the liquid fertilizer. Add SOLVE 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.
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 recommended rate of the 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 recommended 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 recommended 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 recommended on the label. Deeprooted perennial weeds such as Canada thistle and field bindweed and many woody plants usually require repeated applications for effective control.
To prevent misapplication, spot treatments should be applied 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 SOLVE 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 Rate Conversion Table for Spot Treatment table are based on the application rate for an area of 1,000 sq ft. Mix the amount of SOLVE 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 SOLVE 2,4-D required for larger areas, multiply the table value (fl 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.
See “Rate Conversion Table for Spot Treatment” on the label.
Band Application: SOLVE 2,4-D may be applied as a band treatment. Use the formulas on the label to determine the appropriate rate and volume per treated acre.
WHERE TO USE
SOLVE 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 management 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
- 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 recommended 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 AND RANGELAND RESTRICTIONS:
- For susceptible annual and biennial broadleaf weeds do not exceed 2 pints per acre per application. For moderately susceptible biennial and perennial broadleaf weeds and woody plants, do not exceed 4 pints per acre per application.
- Do not apply more than 2 pints per acre per application for spot treatments.
- 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.
