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


To control unwanted hardwood trees such as elm, hickory, oak, and sweetgum in forests and other non-crop areas, apply by injecting at a rate of 1 ml of undiluted AMINE 4 per inch of trunk diameter at breast height (DBH) as measured approximately 4 1/2 ft above the ground. However, injection should occur as close to the root collar as possible and the injection bit must penetrate the inner bark.

Applications may be made throughout the year, but for best results apply between May 15 and October 15. Maples should not be treated during the spring sap flow.

For hard to control species such as ash, maple, and dogwood use 2 ml of undiluted AMINE 4 per injection site or double the number of 1 ml injections.

Note: No Worker Protection Standard worker entry restrictions or worker notification requirements apply when this product is directly injected into agricultural plants.

Precautions and Restrictions:

- Do not use on bentgrass, alfalfa, clover, or other legumes.

- Do not use on newly seeded areas until grass is well established.

- Do not use from early boot to milk stage where grass seed production is desired.

- Do not apply within 30 days of a previous application.

- Preharvest Interval: Do not harvest forage for hay within 7 days of application. 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.

- For grazed areas, the maximum use rate is 4.21 pt/acre of AMINE 4 (2.0 lb of acid equivalent) per application.

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

- Do not make more than two applications per season.

- If grass is to be cut for hay, Agricultural Use Requirements for the Worker Protection Standard are applicable.

- For susceptible annual and biennial broadleaf weeds: Do not apply more than 2.1 pt (1.0 lb ae) per acre per application.

- For moderately susceptible biennial, perennial broadleaf weeds and difficult to control weeds and woody plants: Do not apply more than 4.21 pt (2.0 lb ae) per acre per application.
