Clethodim 2E

Clethodim 2E is a selective postemergence herbicide for control of annual and perennial grasses in a variety of crops. 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.

Product Features
  • Clethodim 2E is a systemic herbicide which is translocated from the treated foliage to the growing points of the leaves, shoots and roots.
  • Clethodim 2E provides excellent tank mix compatibility with a variety of herbicides for more complete weed control on labeled crops.
  • Clethodim 2E can be applied by ground application with optimal weed control when annual grasses and volunteer cereals are in the 2-to 6-leaf stage.
  • Clethodim 2E can be applied by ground, aerial or by chemigation (Onions: dry bulbs and green; and Garlic only).

Direction for use

USE DIRECTIONS FOR ANNUAL GRASSES (EXCEPT FOR IN ESTABLISHED ALFALFA AND MINT)

• Apply only to actively growing grasses at recommended weed heights.

• Apply when the first grass weed species in a mixed grass weed population reaches the recommended growth stage for treatment.

• Use the high rate under heavy grass pressure and/or when grasses are at maximum height.

• Do not apply more than 8 fl. oz./A of Clethodim 2E per application to the following crops: asparagus, carrot, cranberry, cucurbits, flax, fruiting vegetables (except tomato), garden beet, green onion, head and stem brassica vegetables, herbs, hops, leaf petioles, leafy brassica greens. Leafy greens, non-bearing food crops, root vegetables, safflower, sesame and strawberry. Do not apply more than 6 fl. oz./A of Clethodim 2E per application to canola, or mustard seed.

1. Sethoxydim - resistant volunteer corn.

2. Includes Roundup Ready®, Liberty Link® and IMI-CORN® volunteer corn.

3. When the cereal grain crop (such as wheat) is interseeded for crop establishment or is planted as wind breaks to aid crop establishment, the minimum Clethodim 2E use rate for control is 8 fl. oz./A.

4. Rates higher than 8 fl. oz./A may be applied in certain geographic areas, environmental conditions, or cropping situations, where experience has shown that higher rates are needed for satisfactory control of annual grasses. In these situations, rates from 8 to 16 fl. oz./A may be applied. Do not apply more than 8 fl. oz./A of Clethodim 2E per application to the following crops: asparagus, carrot, cranberry, cucurbits, flax, fruiting vegetables (except tomato), garden beet, green onion, head and stem brassica vegetables, herbs, hops, leaf petioles, leafy brassica greens. Leafy greens, non-bearing food crops, root vegetables, safflower, sesame and strawberry. Do not apply more than 6 fl. oz./A of Clethodim 2E per application to canola or mustard seed.

USE DIRECTIONS FOR PERENNIAL GRASSES

• Make applications only to actively growing grasses at recommended weed heights.

• Apply when the first grass weed species in a mixed grass weed population reaches the recommended growth stage for treatment.

• Use the high rate when grasses are at maximum height and/or under heavy grass pressure.

• Do not apply more than 8 fl. oz./A of Clethodim 2E per application to the following crops: asparagus, carrot, cranberry, cucurbits, flax, fruiting vegetables (except tomato), garden beet, green onion, head and stem brassica vegetables, herbs, hops, leaf petioles, leafy brassica greens. Leafy greens, non-bearing food crops, root vegetables, safflower, sesame and strawberry. Do not apply more than 6 fl. oz./A of Clethodim 2E per application to canola or mustard seed.
