Cycloprothrin is used to control rice water weevils and other
insects in paddy rice, fruit, vegetables, tea, cotton, soyabeans and in
forestry.
ChEBI: A carboxylic ester having 2,2-dichloro-1-phenylcyclopropanecarboxylic acid as the acid component and hydroxy(3-phenoxyphenyl)acetonitrile as the alcohol component.
Cycloprothrin is an insecticide, used for controlling insect pests on rice plants and vegetables.
The structure of the acid moiety of cycloprothrin is rather unusual and
thus deserves special attention. The compound has two chiral centres and
therefore is a mixture of four stereoisomers; it is used as such. Degradation
and metabolism studies have been reported for flooded soil, rice
plants and rat. The results show that cycloprothrin is degraded by oxidation,
hydrolysis and conjugation reactions as are other members of the
class. However, metabolism in rice is very slow.
Cycloprothrin is a stable compound but it is hydrolysed under alkaline
conditions. It is relatively stable to photodegradation.
