Description

Isoxadifen-Ethyl CAS NO 163520-33-0 is a highly effective safener used in modern agricultural chemistry to protect crop plants from herbicide injury. Its core value lies in selectively enhancing crop tolerance to specific herbicides, thereby increasing application safety and expanding the usable herbicide spectrum. This compound is essential for agrochemical formulators and agricultural producers seeking to develop and utilize more effective and selective weed control programs in crops like corn and rice.

Application

• Herbicide Safener in Crop Protection: Primarily used as a safener to protect cereal crops, especially corn (maize), from injury caused by certain classes of herbicides, enabling safer and more effective weed management.
• Agrochemical Formulations: A key component in the formulation of combination herbicide products, where it is mixed with active ingredients like foramsulfuron or iodosulfuron to improve crop selectivity.
• Enhancing Herbicide Selectivity: Used to widen the window of application and increase the margin of safety for post-emergence herbicides in sensitive crops.
• Seed Treatment Applications: Employed in seed treatment technologies to provide early-season protection for seedlings against herbicide stress.
• Research & Development: Serves as a reference standard and intermediate in agricultural chemical R&D for developing new crop protection agents and studying safener mechanisms.
