Cyromazine

Chemical properties

White crystalline powder. The solubility in water is 11,000 mg/L at 20°C and pH 7.5, and the hydrolysis is not obvious at pH 5-9.

The Uses of Cyromazine

Cypromazine is a high-efficiency and low-toxicity insecticide. It is mainly used to control leafminer pests, has a good control effect on Liriomyza, and can also be used to control flies.

What are the applications of Application

Cyromazine is an insect growth regulator, used to control fly larvae in livestock and poultry manure. It can be fed directly to livestock or applied directly to fly breeding sites. Cyromazine also exhibits systemic activity and is used as a foliar spray to control leaf miners in vegetables, potatoes, etc., and on mushrooms.

What are the applications of Application

Cyromazine is a non-organophosphorus insect growth regulator

Definition

ChEBI: Cyromazine is a triamino-1,3,5-triazine. It has a role as a triazine insecticide and a mouse metabolite.

Preparation

Cyromazine is prepared by the reaction of cyanuric chloride and cyclopropylamine to obtain 2-Cyclopropylamino-4,6-dichloro-triazepine, and then reacts with ammonia to obtain 2-Cyclopropylamino-4-chloro-6-aminostriazepine, and then reacting with ammonia to produce.

General Description

N-Cyclopropyl-2,4,6-triamino-1,3,5-triazine, also known as cyromazine, is an insect growth regulator(IGR) that is commonly used as an insecticide. It undergoes metabolism in plants and animals to form melamine. Surface-enhanced Raman scattering (SERS) spectroscopic study indicates that it interacts with the surface of silver colloid through the lone pair on nitrogen.

Flammability and Explosibility

Agricultural Uses

Insecticide (insect growth regulator): As an insect growth regulator, cyromazine is fed to caged poultry and is passed through the chicken, leaving a residue in the manure. The chemical controls the growth of the fly larvae developing in the manure. Used as a foliar spray to control leaf miners in vegetables, mushrooms, potatoes and ornamentals and to control flies on animals.

Environmental Fate

Chemical/Physical. Cyromazine will react with mineral acids (e.g., hydrochloric acid, sulfuric acid) forming water-soluble salts

Metabolic pathway

Information presented in this summary is abstracted from the data evaluation published by the Pesticide Safety Directorate (PSD, 1993). The major degradation pathway of cyromazine involves the N-dealkylation of the cyclopropyl moiety to yield melamine. Both cyromazine and melamine are quite stable to biotransformation. Deamination and the formation of N-methylcyromazine were observed as minor pathways.

Degradation

Cyromazine (1) is stable to hydrolysis at pH 5, 7 and 9 and 70 °C for up to 28 days. No degradation of cyromazine was observed when irradiated under mercury vapour lamp (>290 nm) at 25 °C for up to 168 hours.
