Description

Fomesafen, Acidform is a selective, post-emergence herbicide belonging to the diphenyl ether chemical class. This compound is valued for its effective control of broadleaf weeds, particularly in legume crops, by inhibiting the protoporphyrinogen oxidase (PPO) enzyme. It is a critical agrochemical input for agricultural producers and formulators seeking reliable, targeted weed management solutions.

Application

• Primary Use in Soybean Cultivation: Widely applied for post-emergence control of troublesome broadleaf weeds, including velvetleaf, morning glory, and lambsquarters, in soybean fields.
• Use in Other Legume Crops: Employed in crops such as beans and peanuts for selective weed management programs.
• Agrochemical Formulation: Serves as a key active ingredient in the manufacturing of various herbicide formulations, including soluble concentrates (SL) and suspension concentrates (SC).
• Resistance Management Tool: Integrated into weed control strategies to manage and delay the development of herbicide resistance in weed populations.
• Industrial & Non-Crop Use: Utilized in certain non-agricultural settings for vegetation control, subject to local regulatory approvals.
