Description

Fenoxaprop-p-Ethyl CAS NO 71283-80-2 is a highly selective aryloxyphenoxypropionate herbicide, specifically the (R)-enantiomer of fenoxaprop-ethyl, known for its superior herbicidal activity. This compound is a critical active ingredient for the effective post-emergence control of annual and perennial grass weeds in broadleaf crops. It is an essential agrochemical for global agricultural producers, particularly in the cultivation of soybeans, peanuts, rice, and other key crops, where it ensures crop safety and yield protection by targeting problematic grasses.

Application

• Selective Grass Weed Control in Soybeans: Primary application for managing barnyardgrass, crabgrass, foxtails, and other annual grasses.
• Rice Paddy Herbicide: Used in rice fields to control Echinochloa crus-galli (barnyardgrass) and other grass weeds without harming the rice crop.
• Peanut and Other Legume Crops: Protects yield by eliminating competing grass weeds in peanut, bean, and pea cultivations.
• Turf and Ornamental Management: Employed in professional turf management for selective grass control in certain ornamental plantings.
• Formulation Intermediate: Serves as a key technical-grade material for manufacturers producing emulsifiable concentrate (EC), wettable powder (WP), and other commercial herbicide formulations.
• Integrated Weed Management (IWM) Programs: A vital tool in resistance management strategies, often used in rotation with herbicides of different modes of action.
