SWEET CORN - PREPLANT (BURNDOWN) PREEMERGENCE

General Information

Product Information

TENKOZ AMINE 4 herbicide is intended for selective control of many broadleaf weeds in certain crops (cereal grains, corn, grain sorghum, soybeans and sugarcane), orchard floors (pome fruit, including apples and pears, stone fruit, nut orchards and pistachios), fallow cropland, forests, grass pastures, rangeland, Conservation Reserve Program acres, ornamental turf (including turf grown for sod or seed), non-cropland and aquatic areas. Also for control of trees by injection.

Apply AMINE 4 as a water or oil-water spray during warm weather when target weeds or woody plants are actively growing. Application under drought conditions will often give poor results. Use low spray pressure to minimize drift. Generally, the lower dosages listed on the label will be satisfactory for young, succulent growth of susceptible weed species. For less susceptible species and under conditions where control is more difficult, use higher listed rates. Deep-rooted perennial weeds such as Canada thistle and field bindweed and many woody plants usually require repeated applications for satisfactory control. Consult your State Agricultural Experiment stations or Extension Service Weed Specialists for use directions from the label that best fit local conditions.

Use Precautions and Restrictions

Be sure that use of AMINE 4 conforms to all application regulations.

Chemigation: Do not apply this product through any type of irrigation system.

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

Refer in the label for spray drift management and tank mix information.

Application

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, use a spray volume of 3 or more gallons per acre by air and 10 or more gallons per acre for ground equipment. Where states have regulations which specify minimum spray volumes, they must 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 3 gallons total spray volume per acre.

Rate Ranges and Application Timing

Generally, the lower dosages given will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive species and under conditions where control is more difficult, the higher dosages will be needed. Apply AMINE 4 during warm weather when weeds are young and actively growing.

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 in the label.

Band Application: AMINE 4 may be applied as a band treatment. Use the formulas in the label to determine the appropriate rate and volume per treated acre.

Limitations, Restrictions, and Exceptions

CORN (SWEET CORN) - PREPLANT (BURNDOWN) PREEMERGENCE

Use high rate in rate range for less susceptible weeds or cover crops, weeds in advanced stages of development, or under less favorable growth conditions.

Preplant: Apply 7 to 14 days before planting corn to control emerged broadleaf weed seedlings or exiting cover crops.

Preemergence: Apply any time after planting, but before corn emerges to control broadleaf weed seedlings or existing cover crops.

Precautions:

- Preplant or preemergence applications should not be made to light sandy soils.

- 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.

- Note: Corn treated with 2,4-D may exhibit stem brittleness for 8 to 10 days following application. During this period, the crop is more susceptible to stem breakage from cultivation or wind.

Restrictions (Sweet Corn):

- Preharvest interval: Do not harvest ears within 45 days after application.

- Do not use treated crop as fodder for 7 days following application.

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

- Do not make more than one preplant or preemergence application, and one postemergence application per use season.

- Do not apply more than 3.16 pt/acre of AMINE 4 (1.5 lb of acid equivalent) per use season.
