WHEAT AND BARLEY

General Information

GENERAL INFORMATION

Axial Herbicide is a systemic, postemergence herbicide for the control of several grass weed species in all varieties of spring wheat (excluding durum), winter wheat, and barley.

Axial Herbicide is rapidly absorbed by weed foliage and translocated to the growing points of leaves and stems where it inhibits the acetyl CoA carboxylase (ACCase) enzyme. Susceptible weed species generally stop growing within 48 hours of treatment, turn yellow within one to three weeks, and are completely controlled within three to five weeks. Level and rate of control depend on weed species, growing conditions, crop competition, and coverage. Thorough spray coverage of the plants is essential for consistent control.

Although Axial Herbicide does not control broadleaf weeds, it can be tank mixed with a wide range of broadleaf herbicides to provide broad-spectrum one-pass weed control. It can also be tank mixed with Tilt Fungicide, Quilt Fungicide, and Warrior Insecticide with Zeon Technology (restriction: not for use on barley). See the section entitled Tank Mixes of Axial Herbicide with Broadleaf Weed Herbicides, Fungicides, and Insecticides. Herbicides not approved on the label for tank mixing with Axial Herbicide may be applied sequentially. Always apply Axial Herbicide first and allow at least 4 days after application of Axial Herbicide before applying these herbicides sequentially.

Use Rates

Apply the recommended rate of Axial Herbicide and the recommended rate of Adigor Adjuvant using ground or aerial equipment, in a minimum of 5 gals. of water per acre (see Ground and Aerial Application Procedures section for additional information).

APPLICATION PROCEDURES

Timing of Application

Apply Axial Herbicide to all varieties of spring wheat (excluding durum), winter wheat, and barley from the 2-leaf stage to pre-boot stage. Refer to the Crop Use Directions section for grazing and harvest restrictions.

Precaution: Do not apply to a crop that is stressed by conditions such as frost, low fertility, drought, flooding, disease damage, or insect damage, as crop injury may result.

When tank mixing with a broadleaf herbicide, insecticide or fungicide, always refer to the label of the tank mix partner prior to use.

For optimum results, apply Axial Herbicide to actively growing weeds. An early application will maximize crop yields by reducing weed competition. Weed control following application of Axial Herbicide alone or in combination with broadleaf herbicides can be reduced or delayed under conditions of stress, such as drought, heat, insufficient fertility, flooding, and prolonged cool temperatures. Grass escapes or re-tillering may occur if application is made during prolonged conditions of stress. Optimum weed control will be obtained if application of Axial Herbicide is delayed until the conditions of stress have ended and weeds are once again actively growing. Weeds emerging after Axial Herbicide application will not be controlled.

Ground Applications

Water Volume – Use an application rate of 5–10 gals. of water per acre. Use 10 gals. of water per acre under dry conditions or dense weed populations. Application rates of greater than 10 gallons of water per acre should be avoided as reduced grass control may occur.

Aerial Applications

Apply Axial Herbicide in water using a minimum spray volume of 5 gals./A. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. Make applications at a maximum height of 10 ft. above the crop with low-drift nozzles at a maximum pressure of 40 psi and wind speed not exceeding 10 mph to help assure accurate application within the target area.

Limitations, Restrictions, and Exceptions

Wheat and Barley

Axial Herbicide can be used on all varieties of spring wheat (excluding durum), winter wheat, and barley. Do not allow spray to drift to adjacent fields seeded to crops other than wheat or barley. Do not treat wheat or barley underseeded to forages.

To avoid possible illegal residues:

- Make one application per crop season.

- Do not graze livestock or harvest forage for hay from treated areas for a minimum of 50 days following application.

- Do not harvest grain for 60 days following application.

- Do not use on barley which will be grazed by livestock or made into silage for feed.

- Do not apply both Discover and Axial products to the same crop in the same season.

Note: When tank mixing broadleaf herbicides, refer to Tank Mixes of Axial Herbicide with Broadleaf Weed Herbicides, Fungicides, and Insecticides section for exceptions and additional information on weeds controlled.

USE RATES:

Axial Herbicide (8.2 oz./A) + Adigor Adjuvant (9.6 oz./A).

TIMING OF APPLICATION TO WEEDS

Persian Darnel, Volunteer Oat, Wild Oat:

- 1 to 6-leaf stage on main stem.

- Prior to emergence of the 4th tiller.

Giant Foxtail, Green Foxtail, Yellow Foxtail, Italian (Annual) Ryegrass, Canarygrass, Wild Proso Millet, Windgrass:

- 1 to 5-leaf stage on main stem.

- For optimum control, apply prior to emergence of the 3rd tiller and while weeds are actively growing.

For Tank Mix Instructions with Warrior with Zeon Technology for Barley in the state of Idaho, Colorado, Montana refer to the supplemental label.

Restricted Entry Interval

48 hours
