Fenclozine (likely Clofentezine) is primarily used as a selective acaricide in agricultural practices. It is effective in controlling phytophagous mites that infest crops, such as spider mites, by inhibiting egg hatching and larval development, ensuring healthier plant growth and higher yields. Farmers apply it to a variety of crops, including fruits, vegetables, cotton, and ornamental plants, to protect them from damage caused by mite infestations. It has limited activity against insects but is valued for its selectivity, sparing beneficial insects and making it suitable for integrated pest management systems. Its use helps in maintaining crop quality and reducing economic losses due to mite-related damage.
