CORN (FIELD CORN, ETC.) - ANNUAL BROADLEAF WEEDS - POSTEMERGENCE

General Information

GENERAL INFORMATION

This product is intended for selective control of many broadleaf weeds in certain crops, including, cereal grains (wheat, barley, millet, oats and rye), corn (field corn, popcorn and sweet corn), fallowland and crop stubble, sorghum (grain and forage sorghum), and soybeans (preplant burndown application only), forests, rangeland and established grass pastures including Conservation Reserve Program (CRP) areas, non-cropland, grasses grown for seed or sod, and ornamental turf.

Apply this product as water or oil spray during warm weather when weeds or woody plants are actively growing. Application under drought conditions often will give poor results. Use low spray pressure to minimize drift. Generally, the lower dosages recommended on the label will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive species and under conditions where control is more difficult, use higher recommended rates. Deep-rooted perennial weeds such as Canada thistle and Field Bindweed and many woody plants usually require repeated applications for maximum control. Consult your State Agricultural Experiment Stations or local Extension Service Weed Specialists for recommendations from the label that best fit local conditions.

GENERAL USE PRECAUTIONS AND RESTRICTIONS

Excessive amounts of 2,4-D in the soil may temporarily inhibit seed germination and plant growth.

Avoiding Injury to Non-target Plants

Spray drift produced during application is the responsibility of the applicator and care should be taken to minimize off-target movement of spray during application. A drift control agent suitable for agricultural use may be used with this product to aid in reducing spray drift. If used, follow all use recommendations and precautions on the product label.

Do not apply where drift may be a problem due to proximity to susceptible crops or other desirable broadleaf plants. Do not apply this product directly to, or otherwise permit contact with cotton, flowers, fruit trees, grapes, ornamentals, vegetables, or other desirable plants that are susceptible to 2,4-D herbicides. Do not permit spray mist containing 2,4-D to contact susceptible plants since even very small quantities of the spray, which may not be visible, can cause severe injury during either active growth and dormant periods. Do not use in greenhouses.

Ground Equipment: With ground equipment, spray drift can be lessened by keeping the spray boom as low as possible; by applying 10 gallons or more of spray per acre; by using no more than 20 pounds spraying pressure and large droplet producing nozzle tips; by spraying when wind velocity is low; and by stopping all spraying when wind exceeds 10 miles per hour. Do not apply with hollow cone-type insecticide or other nozzles that produce a fine-droplet spray.

Avoid Movement of Treated Soil: Avoid conditions under which soil from treated areas may be moved or blown to areas containing susceptible plants. Wind-blown dust containing 2,4-D may produce visible symptoms when deposited on susceptible plants, however, serious plant injury is unlikely. To minimize potential movement of 2,4-D on wind-blown dust, avoid treatment of powdery dry or light sandy soils until soil is settled by rainfall or irrigation or irrigate soon after application.

Do not store or handle other agricultural chemicals with the same containers used for this product. Do not apply other agricultural chemicals or pesticides with equipment used to apply this product unless equipment has been thoroughly cleaned to remove all traces of 2,4-D.

APPLICATION INSTRUCTIONS

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 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. Do not apply less than 2 gallons total spray volume per acre.

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 oil or other adjuvants unless specifically recommended 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.

Spot Treatments

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 this product in labeled crops. 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 a treatment area of 1,000 sq. ft. Mix the amount of this product (fl. oz. or ml) corresponding to the desired broadcast rate in one (1) or more gallons of spray. To calculate the amount of this product required for larger areas, multiply the table value (fl. oz. or ml) by the number of thousands of sq. ft. of area to be treated. An area of 1,000 sq. ft. is approximately 10.5 x 10.5 yards (strides) in size. To calculate the amount of this product required for a broadcast rate the higher than those listed, use a multiple of the table value, for example, if a spot treatment requires the equivalent of an 8 pt. per acre, use 2x the amount per gallon of spray required for the 4pt/acre rate.

Refer in the label for the Rate Conversion Table for Spot Treatment.

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.

Limitations, Restrictions, and Exceptions

CORN (FIELD CORN, ETC.)

Specific Use Directions

Apply when weeds are small and corn is less than 8 inches tall (to top of canopy). If corn is more than 8 inches tall, use drop nozzles to keep spray off foliage.

Treat perennial weeds when they are in bud to bloom stage.

Do not tank mix with atrazine, oil or other adjuvants.

Do not apply from tasseling to hard dough stage.

Note: Corn treated with 2,4-D may become temporarily brittle. Wind or cultivation may cause stem breakage during the period of time that corn is brittle.

Sweet Corn: To minimize potential for crop injury, use only lowest rate in rate range.

Precautions:

- Corn hybrids vary in tolerance to 2,4-D. Some are easily injured. Apply only to varieties known to be tolerant to 2,4-D. Consult the seed company or your Agricultural Experiment Station or Extension Service Weed Specialist for this information.

- After postemergence application, delay cultivation for 8 to 10 days to allow corn to overcome any temporary brittleness.

Restrictions (Field Corn and Popcorn):

- Preharvest interval: Do not harvest for grain or fodder within 7 days after application.

Restrictions (Sweet Corn):

- Preharvest interval: Do not harvest within 45 days after application or permit meat or dairy animals to forage or graze treated area within 7 days after application.

- Do not make a postemergence application any less than 21 days after a prior application.
