ALFALFA (DORMANT SEASON ON FALL-SEEDED NEWLY ESTABLISHED STANDS) - REGION B

General Information

GENERAL INSTRUCTIONS AND INFORMATION

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

When Gramoxone Max is applied at less than 10 gallons per acre finished spray volume, a drift control or spray deposition additive SHOULD be used. Refer to the additive label for use directions.

GENERAL INFORMATION

Gramoxone Max is a contact herbicide used to control or suppress a broad spectrum of emerged weeds. Gramoxone Max controls most small annual weeds – both broadleaves and grasses, and suppresses perennial weeds by destroying green foliage. Gramoxone Max can also be used as a desiccant/defoliant at harvest.

Gramoxone Max is formulated as a liquid which contains 3 lbs. of active ingredient per gallon. The formulation contains a nontoxic odor and an emetic (an agent which will induce vomiting if the product is swallowed). The odor is included in the formulation to help prevent accidental ingestion of Gramoxone Max.

Gramoxone Max is rapidly absorbed by green plant tissue and interacts with the photosynthetic process to produce superoxides which destroy the plant cells. Gramoxone Max requires actively growing green plant tissue to function. Thorough coverage of all green foliage is essential for effective weed control and for effective crop desiccation/defoliation. Gramoxone Max is not as effective on drought-stressed weeds, weeds with little green foliage (i.e., mowed or cut weeds), or mature woody bark of trees and vines.

Clay and organic matter rapidly tie up Gramoxone Max. As a result, Gramoxone Max has no residual soil activity to affect later-planted crops or later germinating weeds.

RAINFASTNESS

Because Gramoxone Max is rapidly absorbed by the weed foliage, rain occurring 30 minutes or more after application will have no effect on the activity of Gramoxone Max.

APPLICATION

Since Gramoxone Max is a contact-type herbicide, it is essential to obtain complete coverage of target weeds to get good control. Improper application technique and/or application to large, stressed, or mown weeds will usually result in unacceptable weed control and unacceptable crop desiccation/ defoliation. Complete coverage is also essential for good crop desiccation/defoliation. See details below for specific application instructions.

USE OF A NONIONIC SURFACTANT OR CROP OIL CONCENTRATE

Always add one of the following (Failure to use one of the following at recommended rates will result in reduced performance of Gramoxone Max.)

Nonionic Surfactant: Add nonionic surfactant containing 75% or more surface-active agent at 0.125% v/v (1 pt./100 gals.), OR add a nonionic surfactant containing 50-74% surface-active agent at 0.25% v/v (2 pts./100 gals.), of the finished spray volume for ground applications. For aerial applications, add a nonionic surfactant at 0.25% v/v (2 pts./100 gals.) of the finished spray volume.

Crop Oil Concentrate: Add a nonphytotoxic crop oil concentrate containing 15-20% approved emulsifier, at 1.0% v/v (1 gal./100 gals.) of the finished spray volume for ground applications. For aerial applications, add 1 pt. of crop oil concentrate per acre. Do not use crop oil concentrate when using Gramoxone Max for cotton harvest aid.

GENERAL PRECAUTIONS AND RESTRICTIONS

EQUIPMENT/CONTAINER

Flush all spray equipment with water after use each day. Gramoxone Max is corrosive to aluminum. Aluminum spray equipment and aluminum aircraft structures that are exposed to spray solution or spray drift should be flushed thoroughly with water immediately after use.

In dry areas, dust stirred up by high winds or equipment tires can coat weed or plant leaves and reduce Gramoxone Max activity. Avoid applying Gramoxone Max in extremely dusty conditions.

LIMITATIONS AND PRECAUTIONS

- For Cotton Harvest Aid: Do not pasture livestock in treated fields or feed treated foliage.

- DO NOT use around home gardens, schools, recreational parks, or playgrounds.

- In preplant and preemergence (to the crop) uses, do not apply to soils lacking clay minerals, i.e., peat, muck, pure sand, artificial planting media.

- Seedbeds and plantbeds should be formed as far ahead of planting and treatment as possible to permit maximum weed and grass emergence prior to treatment.

- Seeding or transplanting should be done with a minimum amount of soil disturbance.

- Gramoxone Max used for preplant weed control over the top of plastic mulch may damage transplants which come in contact with the plastic. Sufficient rainfall or sprinkler irrigation to cause wash-off prior to planting may be needed to prevent damage to the crop.

- Weeds and grasses emerging after application of Gramoxone Max will not be controlled or suppressed.

- Unless otherwise indicated, crop plants emerged at time of application may be severely injured or killed if contacted by sprays of Gramoxone Max.

Limitations, Restrictions, and Exceptions

ALFALFA (Region B)

Dormant Season On fall-seeded, newly established stands less than 1-year-old

See the map on the label.

Minimum Total Spray Per Acre: Ground - 10 gals.; Air - 5 gals.

Precautions, Restrictions and Comments

- For desiccation of weeds, including London rocket, sowthistle, rescue brome, wild oats, chickweed, ryegrass, bluegrass, cheatgrass, dogfennel, tansymustard, henbit, downy brome, and other winter annuals; and suppression of perennial weeds.

- In the California counties of Orange, Riverside, and all counties north of these counties, do not apply if spring regrowth after grazing or cutting is more than 2”. In all other areas within Region B, do not apply if regrowth after grazing or cutting is more than 2”.

- CAUTION: Applications to alfalfa that is not dormant, or has broken dormancy, may result in stand and/or yield reductions. Replanting may be necessary. Green alfalfa foliage present at the time of application will be burned.

- Total hay yield of first cutting may be reduced in alfalfa fields with severe weed infestation. This reduction will usually be directly proportionate to the loss of weed weight.

- Tank mix with metribuzin (Lexone or Sencor) for improved burndown of weed vegetation and residual weed control in dormant established (at least 1-year old) alfalfa. Consult the metribuzin product label for a list of weeds controlled, rates of application, and precautions.

- Do not apply tank mix with metribuzin on newly established (less than 1-year old) alfalfa.

CALIFORNIA

- For desiccation of weeds including bluegrass, ryegrass, shepherdspurse, chickweed, tansymustard, foxtail, sowthistle and groundsel.

- Use high rate if ryegrass, shepherdspurse, sowthistle or groundsel is present.
