Clethodim

Clethodim (CAS 99129-21-2), sold under trade names including Select, Volunteer, and Ogive, is a post-emergent herbicide active ingredient used to control grass weeds in broadleaf crops.

It targets annual and perennial grasses without affecting the broadleaf crop, making it a standard choice for selective weed management programs in various agricultural settings.

This chemical is applied in soybean, cotton, sunflower, and canola production to eliminate volunteer cereals and invasive grass species after crop emergence has occurred.

In specialty crop programs, it controls difficult perennial grasses such as quackgrass and johnsongrass where residual soil herbicides are not viable for the grower.

Formulators use this substance as the active ingredient in emulsifiable concentrate and suspension concentrate herbicide products registered for commercial agricultural use worldwide.

Contract manufacturers and generic agrochemical producers source technical-grade material for reformulation into branded or private-label crop protection products for the market.

The product is available as a technical-grade active ingredient, typically as a liquid, for use in downstream formulation and large-scale industrial chemical processing.

Standard commercial concentrations in finished herbicide products are commonly 120 g/L and 240 g/L EC formulations, available in bulk and drum quantities for distributors.
