Products Description
Cyenopyrafen (C24H31N3O2) is a new type of acrylonitrile-based acaricide developed by Nippon Shokubai Co., Ltd. of Japan.
Cyenopyrafen is a contact acaricide whose mechanism of action is mainly related to the activation and metabolism of deesterified enols, which inhibits mitochondrial function by disrupting complex II (succinate dehydrogenase) in the respiratory electron transport chain.
Cyenopyrafen has no cross-resistance with the existing mainstream insecticides and can be used for the prevention and control of various mites on crops such as fruit trees, citrus, tea plants, and vegetables.
Mechanism of Action
The mechanism of action is mainly related to the activation and metabolism of deesterified enols. It inhibits mitochondrial function by disrupting complex II (succinate dehydrogenase) in the respiratory electron transfer chain, and the drug has good selectivity.
