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.


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


Apply when weeds are small and actively growing. Use the lower rate in the rate range for small rapidly growing annual or biennial weeds and a higher rate for perennial weeds or for annual or biennial weeds in advanced growth stages or when growing conditions are les than ideal

Postemergence: Apply after crop is fully tillered, (usually4 to 8 inches tall) but not forming joints in the stems.


- Up to 2.5 pt/acre may be applied postemergence to wheat, barley, rye and millet. However, there is greater risk of crop injury at rates greater than 1 1/3 pt/acre and such rates should be used only when the need for weed control justifies additional risk to the crop.

- Do not apply AMINE 4 at the crop seedling stage of growth prior to tillering or from early boot (forming joints in the stem) through milk stage of grain development. Consult state agricultural experiment station or extension service weed specialists for use directions or suggestions to fit local conditions.

- Do not apply if crop is underseeded with legumes.


- Preharvest interval: Do not harvest for grain for 14 days after application.

- Do not apply more than 3.68 pt/acre of AMINE 4 (1.75 lb of acid equivalent) per use season.

- Limit use to no more than one post-emergence application and one pre-harvest application per crop season.
