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


For application to orchard floors, use coarse, low pressure sprays and sufficient water for thorough coverage of weeds.

Apply to annual weeds when small and actively growing.

Apply to perennial weeds from bud to bloom stage.


- To avoid tree injury, do not allow spray drift to contact foliage, fruit, stems, trunks or trees or exposed roots.

- Do not apply when orchards are blooming.

- Do not make orchard floor applications in areas with light sandy soils.

- Avoid application immediately before irrigation and withhold irrigation for 2 days before and 3 days after application.

- Newly established trees or young orchards are more susceptible to 2,4-D injury. Apply only to orchards that have been established for at least one year and are in vigorous growth condition.


- Preharvest Intervals:

Apples and Pears: Do not harvest fruit within 14 days after application.

- Do not cut orchard floor forage for hay within 7 days after application.

- Do not make more than 2 applications per year.

- Stone Fruits, Apples and Pears: Allow at least 75 days between applications.

- Do not apply more than 8.42 pt/acre of AMINE 4 (4.0 lb of acid equivalent) per use season.
