CLETHODIM is a selective postemergence herbicide for control of annual and perennial grasses. CLETHODIM does not control sedges or broadleaf weeds. CLETHODIM is not recommended for use on vegetable crops being grown for seed production unless specific use directions are provided in the label.

In some grass species, repeated use of CLETHODIM (or similar postemergence grass herbicides with the same mode of action) may lead to the selection of naturally-occurring biotypes that are resistant to these products.

A resistant biotype may be present if poor performance occurs and cannot be attributed to adverse weather or application conditions.

This will most likely 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 CLETHODIM to contact 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

A reduction in vigor and growth is evident in treated grass weeds. 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.

APPLICATION INFORMATION

Application Timing

Apply CLETHODIM postemergence to actively-growing grasses according to rate table recommendations in the label. Do not apply to grass plants under stress from insufficient moisture or cold temperatures, or to grass plants exceeding recommended growth stages as unsatisfactory control may result.

In arid regions where irrigation is used to supplement limited rainfall, CLETHODIM should be applied as soon as possible after an irrigation (within 7 days). In arid regions, a second application of CLETHODIM 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 CLETHODIM may reduce weed control. DO NOT APPLY CLETHODIM if rainfall is expected within one hour, since control may be reduced.

Ground Application

Use a minimum of 5 gallons and a maximum of 40 gallons of spray solution per acre. Use of sufficient spray volumes and pressure is essential to ensure complete coverage. Under the following conditions a minimum of 10 gallons 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 gallons 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, and shallots (dry bulbs and green) should be made in a minimum of 20 gallons of spray solution per acre.

Air Application

Use a minimum of 3 gallons of spray solution per acre. As grass or crop foliage becomes dense, increase spray volume up to 10 gallons. For onions (dry bulbs and green), garlic, or shallots (dry bulbs and green): When applying by air do not exceed 8 fl. oz./A in a single application. In California, air applications to onions, garlic or shallots should be made in a minimum of 20 gallons of spray solution per acre.

NOTE: Crop injury may occur when CLETHODIM is applied to onions, garlic, or shallots with aerial equipment.

Spot Treatment

When using hand sprayers or high-volume sprayers utilizing hand guns, mix 1/4% to 1/2% (0.33 oz. to 0.65 oz. per gallon) CLETHODIM 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. per gallon) by volume. For uses requiring non-ionic surfactant, include non-ionic surfactant at 1/4% (0.33 oz. per gallon) by volume.

NOTE: If CLETHODIM 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.

RESTRICTIONS AND LIMITATIONS

General

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

Do not apply a postemergence broadleaf herbicide within one day following application of CLETHODIM or reduced grass control may result.

CLETHODIM 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. of CLETHODIM (0.08 lb. ai) per acre per season. For clover and radish crops, do not apply more than 16 fl. oz. of CLETHODIM (0.28 lb. ai) per acre per season. For all other crops, do not apply more than 32 fl. oz. of CLETHODIM (0.50 lb. ai) per acre per season.

Application on Long Island, New York, is restricted to no more than 16 fl. oz. of CLETHODIM (0.25 lb. ai) per acre per season.

Do not apply more than 8 fl. oz./A of CLETHODIM 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), 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 CLETHODIM 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 CLETHODIM 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 CLETHODIM effectively, and will be less susceptible to herbicide activity.

Best perennial grass control can be obtained if rhizomes or stolons are cut up by preplant 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, result in a very staggered, non-uniform weed emergence. Due to this non-uniform weed emergence, no fewer than two CLETHODIM applications 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 CLETHODIM.

While all vegetable crops on the label have been tested and are tolerant to CLETHODIM, not all specialty varieties of these crops have been tested. It is advised that, before applying CLETHODIM 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 speckling 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 CLETHODIM and broadleaf herbicides may result in reduced grass control. If grass regrowth occurs, an additional application of CLETHODIM may be necessary.

Limitations, Restrictions, and Exceptions

CROPS - RATE: 6-16 FL OZ/ACRE

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

Acceptable crop-oil concentrates would be those which contain a minimum of 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.

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 CLETHODIM applications, in addition to the recommended rate of crop-oil concentrate.
