Fenoxaprop-p-ethyl + Mefenpyr-diethyl 7.5% EW is a post-emergence herbicide designed for cereal crops, effectively controlling annual and perennial grassy weeds. The combination of Fenoxaprop-p-ethyl and Mefenpyr-diethyl ensures high efficacy and improved weed management.
Product Name: Fenoxaprop-p-ethyl + Mefenpyr-diethyl
Chemical Group: Aryloxyphenoxypropionate (Fenoxaprop-p-ethyl) and Safener (Mefenpyr-diethyl)
Formulation Types: EC (Emulsifiable Concentrate), EW (Emulsion, Oil in Water)
Typical Concentrations: Fenoxaprop-p-ethyl 6.9% EC + Mefenpyr-diethyl 3.45% or similar formulations depending on the product.
Product Overview Fenoxaprop-p-ethyl Mefenpyr-diethyl
It is a selective post-emergence herbicide combination specifically developed for the control of annual and perennial grasses in broadleaf crops. Fenoxaprop-p-ethyl, the primary active ingredient, targets a wide range of grassy weeds, while Mefenpyr-diethyl acts as a safener to protect certain sensitive crops from herbicidal injury. This combination provides effective grass weed control with excellent crop safety, making it ideal for use in cereals and various other crops.
Mechanism of Action
Fenoxaprop-p-ethyl: Belongs to the group of aryloxyphenoxypropionate herbicides, also known as “FOP” herbicides. It inhibits the enzyme acetyl-CoA carboxylase (ACCase), which is essential for fatty acid biosynthesis in grasses. By blocking this enzyme, Fenoxaprop-p-ethyl disrupts lipid synthesis, leading to cell membrane disruption, cessation of plant growth, and eventual weed death.
Mefenpyr-diethyl: A safener that protects specific cereal crops like wheat and barley by enhancing the crop’s ability to metabolize Fenoxaprop-p-ethyl rapidly, thereby reducing the potential for crop injury. This allows for selective targeting of weeds without harming the main crop.
Application and Crop Suitability
Fenoxaprop-p-ethyl + Mefenpyr-diethyl is highly suitable for post-emergence control of grass weeds in the following crops:
Wheat (Spring and Winter): Provides excellent control of various grassy weeds, including wild oats, foxtails, and barnyard grass, without impacting the wheat crop. Mefenpyr-diethyl acts as a safener, ensuring that the crop remains unharmed even at the higher doses required for tough-to-control weeds.
Barley: Offers selective control of grass weeds, enabling farmers to manage weed populations effectively and minimize competition for nutrients and water.
Other Cereals (Rye, Triticale, Oats): Safely controls grassy weeds in these crops due to the protective action of the safener.
Target Weeds
Fenoxaprop-p-ethyl + Mefenpyr-diethyl is effective against a broad range of annual and perennial grass weeds, including:
Wild Oats (Avena spp.)
Foxtail (Setaria spp.)
Barnyard Grass (Echinochloa crus-galli)
Crabgrass (Digitaria spp.)
Canary Grass (Phalaris spp.)
Volunteer Grasses: Such as volunteer cereals and other grass species that can be problematic in fields.
