Description

Fenoxaprop-p-ethyl (CAS 71283-80-2 ) is a selective post-emergent herbicide active ingredient used in crop protection to control grass weeds in broadleaf crops. It belongs to the aryloxyphenoxypropionate chemical class and acts by inhibiting acetyl-CoA carboxylase in target grasses. Procurement is driven by demand from agrochemical formulators, generic manufacturers, and registrants developing herbicide products for global markets. It is the primary active ingredient in formulated herbicides targeting annual and perennial grass weeds. Targeted species include wild oat, blackgrass, and ryegrass in wheat, barley, rice, and soybean crops. Formulators incorporate it into emulsifiable concentrate and oil dispersion products, often combined with safeners to broaden crop tolerance. Contract manufacturers source it as a technical-grade active for generic herbicide registration under FAO /WHO specifications. It is also used in turf and non-crop applications where selective grass control is required. This chemical allows for effective management without damaging broadleaf vegetation in diverse agricultural settings. Fenoxaprop-p-ethyl is supplied as a technical-grade solid or concentrated liquid for industrial use. Purity levels are typically at 93% or above for formulation use, ensuring high efficacy in final products. It is available under international agrochemical registration standards to meet global regulatory needs. Packaging ranges from drum quantities to bulk supply depending on formulation-scale requirements. This flexibility supports both large-scale manufacturing and specialized agricultural chemical production facilities. Contact us for supply of Fenoxaprop-p-ethyl Request Quote
