Buprofezin 噻嗪酮
Introduction: Buprofezin is an insecticide used for control of insect pests such as mealybugs, leafhoppers and whitefly on vegetable crops. It is a growth regulator, acting as an inhibitor of chitin synthesis. It is banned in some countries due to its negative environmental impacts, being especially toxic to aquatic organisms as well as non-target insects, though is of low toxicity to humans and other mammals.

ENVIRONMENTAL FATE
Animals Low residues were found in nearly all ruminant and poultry tissues. Extensive metabolism was observed, with a large number of minor metabolites being produced Plants Limited metabolism in most plant species; minor metabolites indicate a pathway involving hydroxylation or oxidative loss of the tert-butyl group, followed by opening of the heterocyclic ring. Soil/Environment DT50 (25 °C) 104 d (flooded conditions, silty clay loam, o.c. 3.8%, pH >6.4), 80 d (upland conditions, sandy loam, o.c. 2.4%, pH 7.0).
Usage: Buprofezin was developed by Nikon Nohyaku Co., Ltd.. It is a moulting inhibitor, thiadiazine insecticide for whitefly and other insect control, such as Whitefiles, Leaf- and plant-hoppers, Scale insects, Lady beetles, Mealybugs, on citrus crops, top fruit, cucumbers, tomatoes;, sweet potatoes, rice, cotton, and etc.
Application: Biochemistry Probable chitin synthesis and prostaglandin inhibitor. Hormone disturbing effect, leading to suppression of ecdysis. Mode of action Persistent insecticide and acaricide with contact and stomach action; not translocated in the plant. Inhibits moulting of nymphs and larvae, leading to death. Also suppresses oviposition by adults; treated insects lay sterile eggs. Uses Insecticide with persistent larvicidal action against Homoptera, some Coleoptera and also Acarina. Effective against Cicadellidae, Deltocephalinae (leafhoppers) and Delphacidae (planthoppers) in rice, at 50-250 g/ha; Cicadellidae (lady beetle) in potatoes; Aleyrodidae (whitefly) in citrus, cotton and vegetables, at 0.025-0.075 g/ha; Coccidae, Diaspididae (scale insects) and Pseudococcidae (mealybugs) in citrus and top fruit, at 25-50 g/hl; Tarsonemidae in vegetables, at 250-500 g/ha. Suitable for IPM programmes.
