Hexaflumuron

Melting point ：202～205℃ Vapor pressure: 0.059mPa (25°C) toxic LD50(mg/kg):Acute transoral greater than 5000 rats, rats acute transdermal greater than 5000; Acute inhalation of LC50 (4h) in rats > 2.5 mg/L (maximum concentration reached).In field conditions, there is only a significant hazard to water lice. Both contact with bees and oral LD50 are greater than 0.1 mg/bee. Properties: colorless (or white) solid. Dissolution: Solubility (20 °C): 0.027 mg/L (18°C) in water, 11.9 mg/L in methanol, 5.2 g/L in xylene.Uses: This product is benzoyl urea insecticide, is several mass synthesis inhibitors, with high insecticidal and ovidicidal activity, and fast-acting, especially the control of cotton bollworm.It is used in cotton, potatoes and fruit trees to control a variety of Coleoptera, Diptera, and Homoptera insects. Coleoptera, Diptera, Homoptera and Lepidoptera insects on cotton and fruit trees can be controlled at 25 to 50 g/ha (cotton) and 10 to 15 g/hL (fruit trees). Field tests have shown that the insecticide can kill pests by inhibiting molting, but also inhibit the rate of pests eating, so it has a faster knocking force.For example, for the control of cabbage diamondback moth and cabbage caterpillar, spray at 15-30g/ha, and for control of citrus leaf miner at 37.5-50mg/L. preparation or sources: from 2,6-F2C6H3CONCO and 3,5-dichloro-4-(2-chloro-1,1,2,2-tetrafluoroethoxy) aniline in toluene reflux reaction obtained. Or 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)aniline reacts with oxalyl chloride to give 3,5-dichloro-4-(1,1,2,2 -Tetrafluoroethoxy) phenyl isocyanate can also be obtained by reacting with 2,6-difluorobenzamide. Remarks: Strongly adsorbed by various soils. Category: Insecticides
