  • Applications

    Fenpyroximate is an acaricidal active ingredient used in agriculture to control mite pests such as spider mites on a wide range of crops. It acts as a mitochondrial electron transport inhibitor, providing contact and residual control in both greenhouse and field settings. It is commonly formulated as emulsifiable concentrates (EC), suspensions (SC), or water-dispersible granules (WG) and applied as foliar sprays or integrated into fertigation and spray programs within IPM. Typical application areas include fruit crops (apples, berries), vegetables (tomatoes, cucumbers), ornamentals and nursery crops, and other high-value crops where mite pressure is a concern. Its use is subject to local regulations and formulation limits.
