CAS 66441-23-4: Fenoxaprop-ethyl

Description: Fenoxaprop-ethyl is a selective herbicide primarily used for controlling annual grasses in various crops, particularly in rice and wheat. It belongs to the aryloxyphenoxypropionate class of herbicides, which function by inhibiting the enzyme acetyl-CoA carboxylase, crucial for fatty acid synthesis in plants. This inhibition disrupts the growth of target weeds while being less harmful to broadleaf crops. Fenoxaprop-ethyl is characterized by its relatively low toxicity to mammals and its moderate persistence in the environment, which necessitates careful management to minimize potential ecological impacts. It is typically applied post-emergence, allowing for effective weed control without adversely affecting the crop. The compound is often formulated as an emulsifiable concentrate or a water-soluble formulation, enhancing its application versatility. Additionally, fenoxaprop-ethyl is subject to regulatory assessments to ensure its safe use in agricultural practices, reflecting ongoing efforts to balance effective weed management with environmental protection.
