Applications :
1 ) Biochemistry : probable chitin synthesis and prostaglandin inhibitor. Hormone disturbing effect, leading to suppression of ecdysis
2 ) Action : persistent insecticide and acaricide with contact and stomach action; not translocated in the plant. Inhibits molting of nymphs and larvae, leading to death. Also suppresses oviposition by adults; treated insects lay sterile eggs.
3 ) Uses :
a ) Insecticide with persistent larvicidal action against Homoptera, some Coleoptera and also Acarina
b ) Effective against Cicadellidae and Delphacidae ( leafhoppers ) in rice; Cicadellidae in potatoes; Aleyrodidae ( whitefly ) in citrus, cotton and vegetables; Coccidae, Diaspididae ( scale insects ) and Pseudococcidae ( mealy bugs ) in citrus.
