What is Azocyclotin?

The Uses of Azocyclotin

Azocyclotin is an organotin aracacide used in the control of mites. Azocyclotin showed weak antifeedant activity against other insects such as Spodoptera littoralis.

The Uses of Azocyclotin

Azocyclotin is used to control all motile stages of spider mites on fruit, vines, hops, cotton, vegetables and ornamentals.

What are the applications of Application

Azocyclotin is an organotin contact acaricide effective against phytophagous mites

Definition

ChEBI: A member of the class of triazoles that is 1,2,4-triazole substituted at position 1 by a tricyclohexylstannyl group.

Metabolic pathway

The sedimentation of particles coated with the pesticide is relatively fast. Shortly after application of 14C-azocyclotin, distribution, solubilizing, and metabolism in fresh water microcosms begin, and azocyclotin is quickly hydrolyzed to cyhexatin (tricyclohexyltin hydroxide) by splitting of the triazole residue, and, according to the solubility of cyhexatin, cyhexatin is mainly absorbed to sediment and the layer of biota in direct contact with the sediment and further undergoes successive metabolism to result in dicyclohexyltin oxide and cyclohexyltin acid.

Degradation

Azocyclotin undergoes hydrolysis with DT₅₀ values (22 °C) of 96 hours at pH 4,81 hours at pH 7 and 8 hours at pH 9 (I'M).
