Albaugh AgriStar Clethodim 2E Herbicide
Albaugh AgriStar Clethodim 2E Herbicide is a selective, post-emergence grass herbicide designed to control many labeled annual and perennial grasses in agricultural crops, ornamentals, conifer sites, and non-crop or fallow areas. Greenbook identifies AgriStar Clethodim 2E as an Albaugh herbicide with clethodim as the active ingredient and EPA Reg. No. 42750-72; Albaugh’s current Clethodim 2E product information lists the same EPA registration and 2.0 lb/gal clethodim formulation.
This systemic grass herbicide is absorbed by treated foliage and moves to the growing points of grass leaves, shoots, and roots. Treated grasses typically show reduced vigor, followed by yellowing/necrosis and gradual foliage collapse, with visible symptoms generally appearing within 7 to 14 days depending on grass species and environmental conditions.
Albaugh AgriStar Clethodim 2E is ideal for managing unwanted grasses in labeled broadleaf crops and ornamental plantings, but it does not control sedges or broadleaf weeds. For broader weed control, consult the product label for approved tank-mix options and restrictions.

| Broad labeled use range |
Labeled crops include alfalfa, clover, beans, cotton, peanuts, potatoes, sugar beets, herbs/spices, ornamentals, and many other sites.
|
| Volunteer corn control |
Albaugh lists Clethodim 2E as an option for volunteer corn control in soybeans.
|
| Flexible application methods |

Christmas tree farms, conifer nurseries, and conifer plantations; not for use in forests.
|
| Fallow & Non-Crop Areas |
Fallow land, non-producing agricultural areas, rights-of-way, fence lines, storage yards, rail yards, and similar labeled sites.
|
| Weed Spectrum |
Labeled grasses include crabgrass, foxtails, barnyardgrass, ryegrass, volunteer cereals, bermudagrass, Johnsongrass, and other annual or perennial grasses.
|
Application & Mixing Highlights
Always follow the label on the product container. Rates vary by crop, grass species, weed height, geography, and application method.
| Application Scenario |
Label-Based Guidance |
| General fallow land use |
6–8 fl oz/A for annual grasses and 8–16 fl oz/A for perennial grasses.
|
| Ornamentals, broadcast use |
The crop-use table lists 6–16 fl oz/A for ornamentals; many ornamental annual/perennial grass tables list 8–16 fl oz/A, with some lower-rate exceptions such as smaller volunteer corn and annual bluegrass.
|
| Spot treatment / hand sprayer |
Official Albaugh label language lists ¼%–½%, equal to about 0.33–0.65 fl oz per gallon, applied to wet vegetation without runoff.
|
| Adjuvant use |
Most grass herbicide applications require the label-specified adjuvant. For ornamentals, the label advises non-ionic surfactant at 0.25% v/v and notes crop oil concentrate is not advised because it may injure flowers and foliage.
|
| Rainfast consideration |
Do not apply if rainfall is expected within 1 hour, because reduced control may occur.
|
Important Precautions & Restrictions
| Safety / Use Point |
Label-Based Summary |
| Reentry |
Agricultural uses have a 24-hour restricted-entry interval; non-agricultural areas should not be entered without protective clothing until sprays have dried.
|
| Desirable grasses |
Do not allow spray to contact desirable grass crops such as corn, rice, sorghum, small grains, or turf, because injury or death may occur.
|
| Grass stress |
Do not apply to drought-stressed or otherwise stressed grasses; poor growing conditions can reduce absorption and performance.
|
| Broadleaf herbicide timing |
Do not apply a post-emergence broadleaf herbicide within one day after Clethodim 2E, as grass control may be reduced.
|
| Legal use |
Federal law requires pesticide products to be used according to labeling. |
