性状:敌百虫(Trichlophonus)分子式:C_4H_3O_4Cl_3P,呈白色结晶状,有芳香味,易溶于水,在酸性条件下较稳定,在中性或碱性溶液中发生水解,生成毒性更大的敌敌畏,水解进一步继续,最终分解成无杀虫活性的物质。作用与用途:本品是一种高效、低毒、低残留的有机磷杀虫剂,其水解后能产生一种胆碱脂酶的抑制剂,使胆碱脂酶的活性受到抑制,失去水解破坏乙酰胆碱的能力,从而使昆虫、甲壳类、蠕虫等动物的神经传导受阻后中毒死亡。本品广泛用于防治鱼体内外寄生虫引起的鱼病。此外,还可杀死水中枝角类和桡足类、敌害水生昆虫和某些敌害鱼类。
Characters: Trichlophonus Molecular formula: C_4H_3O_4Cl_3P, white crystalline, aromatic, easily soluble in water, more stable under acidic conditions, hydrolysis occurs in neutral or alkaline solution to produce more toxic dichlorvos , Further hydrolysis continues, eventually decomposed into insecticidal activity of the material. Function and use: This product is a high efficiency, low toxicity, low residual organophosphate insecticide, its hydrolysis can produce a cholinesterase inhibitor, cholinesterase activity was inhibited, loss of hydrolysis The ability to destroy acetylcholine, so that insects, crustaceans, worms and other animals blocked the nerve conduction poisoning death. This product is widely used in the prevention and treatment of fish diseases caused by parasites inside and outside. In addition, it can kill amphipods and copepods, kill aquatic insects and some predatory fish.
