Description

Cyhalofop-Butyl is a selective aryloxyphenoxypropionate (AOPP) herbicide used for post-emergence control of grass weeds. It is a critical tool for crop protection, offering effective management of resistant and difficult-to-control grass species in broadleaf crops. This product is essential for agricultural professionals and formulators seeking reliable, high-purity active ingredients for the production of advanced herbicide formulations.

Application

• Primary use as a selective post-emergence herbicide for controlling annual and perennial grass weeds.
• Formulation into emulsifiable concentrates (EC), suspension concentrates (SC), and oil-in-water emulsions (EW) for agricultural use.
• Key application in rice paddies for the control of barnyardgrass (Echinochloa crus-galli) and other grassy weeds.
• Use in broadleaf crops such as soybeans, cotton, and peanuts to manage grass competition without crop injury.
• Management of herbicide-resistant grass weed biotypes, including those resistant to acetyl-CoA carboxylase (ACCase) inhibitors.
• Integrated weed management (IWM) programs to reduce reliance on single modes of action.
