|Overview||Chlorfluazuron is a benzoylurea fluorinated nitrogen heterocyclic pesticide with unique mechanism of action, high efficiency, low toxicity and being environmentally friendly. It can be used in vegetables, cotton, fruit trees and pine trees. It is mainly used for controlling Pieris rapae, Plutella xylostella, Helicoverpa armigera, apple peach moth, and pine caterpillars. Its prevention and cure effect is remarkable, especially for the control of vegetable pests; it is expected that it is one of the main varieties that replace the current highly toxic pesticide, providing a new pesticide variety for the production of green food.|
|Chemical properties||Pure product appears as white or yellowish white tasteless crystalline powder with a melting point of 226.5 ℃ (decomposition). It is hard to be dissolved in water, being easily soluble in ketones, aromatic hydrocarbons and alcohols. Stable under light and heat, stable under neutral and weak acid conditions; it is easily subject to decomposition to alkali treatment.|
Pure product appears as white odor-free crystal. m. p. 232-233.5 ° C, relative density 1.4977 (20 ° C), vapor pressure <1 x 10-10 Pa (20 ° C). Solubility: cyclohexanone 110g / L, acetone 52.1g / L, ethyl acetate 45.7g / L, ethylene dichloride 22g / L, toluene 6.5g / L, xylene 3g / L, methanol 2.5 (2.2) g / L, ethanol 2.0 g / L, n-octanol 1 g / L, hexane 10 mg / L and water 0.016 mg / L. Stable at room temperature; stable to light. The proto-drug is yellow-brown crystal with a melting point of220 ~ 223.9 ℃.
|Characteristics||It is of gastric poisoning, contact kill (inhibition of chitin synthesis) effect with high efficacy against pests, but the efficacy is slow. The mechanism of action is through inhibition of chitin synthesis, hindering insect normal molting, egg hatching, larvae molting and pupal developmental deformity and block of adult feather.|
An overview of chlorfluazuron, physical and chemical properties, characteristics, synthesis, precautions, etc. are edited by Shi Yan, Chemicalbook. (2015-11-17)
|Application||Benzoyl urea insect growth regulator. Major effect is through stomach poisoning, coupled with strong contact action. Its permeability is poor with no endosuction effect.|
Insecticidal mechanism is through inhibiting the formation of chitin, hindering the normal molting, causing egg hatching, larvae molting, kidney malformations, adult emergence and obstruction of eggs, so as to achieve the effect of insecticide. It has high activity and slow acting speed, and has a longer half-life in larvae. The agent is a broad-spectrum insecticide and is effective against various Lepidoptera pests and Diptera, Orthoptera and Hymenoptera. It is quite effective on insects on the vegetables, can also be used to control a variety of pests on cabbage, cotton, tea trees and fruit trees.
