This product is a selective post-emergence herbicide for control of annual and perennial grasses.

This product does not control sedges or broadleaf weeds. Repeated use of this product (or similar post-emergence grass herbicide with the same mode of action) may lead to the selection of naturally occurring biotypes that are resistant to these products in some grass species.

If poor performance occurs and cannot be attributed to adverse weather or application conditions, a resistant biotype may be present. This is most likely to occur in fields where other control strategies such as crop rotation, mechanical removal, and other classes of herbicides are not used from year to year.

Do not allow this product to come in contact with desirable grass crops such as corn, rice, sorghum, small grains, or turf, as these and other grass crops will be injured or killed. Minor leaf spotting may occur on treated plants under certain environmental conditions. New foliage is not affected.

Control Symptoms

Treated grass weeds show a reduction in vigor and growth. Early chlorosis/necrosis of younger plant tissue is followed by a progressive collapse of the remaining foliage. Symptoms will generally be observed in 7 to 14 days depending on grass species treated and environmental conditions.


Timing of Applications

Apply this product post-emergence to actively growing grasses according to rate table recommendations.

Applications made to grass plants stressed by insufficient moisture or cold temperatures or to grass plants exceeding recommended growth stages may result in unsatisfactory control. Do not apply under these conditions.

In arid regions where irrigation is used to supplement limited rainfall, this product should be applied as-soon-as possible after an irrigation (within 7 days). In arid regions, a second application of this product will generally provide more effective control of perennial grass weeds than a single application.

Make second application to actively growing grass 2 to 3 weeks after emergence of new growth.

Cultivation of treated grasses 7 days prior to or within 7 days after application of this product may reduce weed control. Do Not Apply this product if rainfall is expected within one hour since control may reduced.

Ground Application

Use of sufficient spray volumes and pressure is essential to ensure complete coverage. Use a minimum of 5 gals. and a maximum of 40 gals. of spray solution per acre. Under the following conditions a minimum of 10 gals. per acre is required: narrow row soybeans, broadleaf herbicide tank mixes, perennial grasses, volunteer corn, drought or stress conditions, heavy grass pressure, or when grasses are at or near maximum height. Failure to use a minimum of 10 gals. per acre under these conditions can result in poor coverage and reduced grass control requiring repeat applications.

Spray pressures should reflect a minimum of 30 psi and a maximum of 60 psi at the nozzle.

Do not use flood nozzles.

Applications to onions (dry bulbs and green), garlic, or shallots (dry bulbs and green) should be made in a minimum of 20 gals. of spray solution per acre.

Air Application

Use a minimum of 3 gals. of spray solution per acre. Increase spray volumes up to 10 gals. as grass or crop foliage becomes dense.

For onions (dry bulbs and green), garlic, or shallots (dry bulbs or green): When applying by air do not exceed 8 fl. oz./A in a single application.

Note: Crop injury may occur when this product is applied to onions, garlic or shallots with aerial equipment.

Spot Treatment

When using hand sprayers or high volume sprayers utilizing handguns, mix 0.25% to 0.50% (0.33 oz. to 0.65 oz./gal.) of this product and treat to wet vegetation while not allowing runoff of spray

solution. For uses requiring crop oil concentrate, include crop oil concentrate at 1% (1.3 oz./gal.) by volume. For uses requiring non-ionic surfactant, include non-ionic surfactant at 0.25% (0.33 oz./gal.) by volume.

Note: If this product is applied as a spot treatment, care should be taken to not exceed the maximum rate allowed on a \"per acre\" basis or crop injury may occur.



Do not apply if rain is expected within 1 hour of application as control may be unsatisfactory.

Do not apply a post-emergence broadleaf herbicide within one day following application of this product or reduced grass control may result.

This product is not recommended for use on vegetable crops being grown for seed production unless specific use directions are provided.

For canola, flax, and mustard seed crops, do not apply more than 5 fl. oz./A of this product per season.

For clover and radish crops, do not apply more than 16 fl. oz./A of this product per season. For all other crops, do not apply more than 32 fl. oz./A of this product per season. Application on Long Island, New York is restricted to no more than 16 fl. oz./A of this product per season.

Do not apply more than 8 fl. oz./A of this product per application to the following crops: garden beets, carrots, radish (and other root vegetables), green onions, leaf lettuce, broccoli, cabbage, cauliflower (and other head and stem brassica vegetables), mustard greens (and other leafy brassica greens), spinach, celery, rhubarb (and other leaf petioles), cranberry, cucurbits, fruiting vegetables (except tomatoes), non-bearing food crops, and strawberry. Do not apply more than 5 fl. oz./A of this product per application to canola, flax or mustard seed. Exceeding these recommendations may result in unacceptable crop injury.

Do not apply under conditions of stress. Applying this product under conditions that do not promote active grass growth will reduce herbicide effectiveness. These conditions include drought, excessive water, extremes in temperature, low humidity, and grasses either partially controlled or stunted from prior pesticide applications. Grasses under these kinds of stressful conditions will not absorb and translocate this product effectively and will be less susceptible to herbicide activity.

Best perennial grass control can be obtained if rhizomes or stolons are cut up by pre-plant tillage practices (discing, plowing, etc.) to stimulate maximum emergence of grass shoots. Cultural practices, such as continuous no-tillage in which the perennial grass rhizomes or stolons are not cut up, results in a very staggered, non-uniform weed emergence. Due to this non-uniform weed emergence, no fewer than two applications of this product per season per year are recommended at the appropriate weed-growth stage rate under continuous no-till conditions.

Grass crops such as corn, rice, sorghum, small grains, or turf, etc. are highly sensitive to this product.

While all the vegetable crops on the label have been tested and are tolerant to this product, not all specialty varieties of these crops have been tested. It is advised that, before applying this product to specialty varieties of vegetable crops on the label, crop tolerance be investigated first using a small section of the field. It is possible that injury symptoms can occur. Symptoms may appear as leaf specking or stunting.

Always read and follow the restrictions and limitations for all products whether used alone or in a tank mix. The most restrictive labeling of any product used applies in tank mixtures, including all crop rotational and other crop restrictions.

Tank mixes of this product and broadleaf herbicides may result in reduced grass control. If grass re-growth occurs, an additional application of this product may be necessary.

Refer in the label for tank mix information.

Limitations, Restrictions, and Exceptions


- 1 qt. by ground or 1% v/v (but no less than 1 pt./A) by air


The addition of AMS has shown improved grass control for difficult to control species, including quackgrass, rhizome johnsongrass, red rice, wild oats, volunteer cereals, and volunteer corn.

(1) This product is not recommended for use on vegetable crops being grown for seed production unless specific use directions are provided.

(2) Acceptable crop oil concentrates would be those which contain a minimum 80% oils and 15% emulsifier. A crop oil concentrate must contain either a petroleum or vegetable oil base and must meet all the following criteria: be non-phytotoxic, contain only EPA-exempt ingredients, provide good mixing quality, and be successful in local experience. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. See the Addition of Adjuvant And Crop Oil Concentrate section for further information.

(5) 1 to 2 qts./A of liquid fertilizer (10-34-0, 28% N or 32% N) or an equivalent amount (2.5 to 4.0 lbs./A) of spray grade ammonium sulfate (AMS) may be added to applications of this product in addition to the recommended rate of crop oil concentrate.
