辛硫磷(phoxim)又名倍氰松、肟硫磷,化学名称为O-苯基氰基醛肟基-0,0-二乙基硫逐磷酸酯,分子式为C_(12)H_(15)N_2O_3PS.它具有强烈的触杀和胃毒作用,对高等动物低毒(雄大鼠口服致死中量2170毫克/公斤),目前已广泛用于防治多种作物害虫,包括地下害虫和仓库害虫.1984—1985年,我们用~(14) -辛硫磷进行拌种和喷施,研究辛硫磷在春小麦植株和土壤中的残留规律,并测定辛硫磷在收获籽粒的面粉和麸皮中的残留量,提出辛硫磷在小麦上的施用安全标准.
Phoxim, also known as betamethrin and oxime, has the chemical name O-phenylcyloxaloxyl-O, O-diethyl thiophosphate with the molecular formula of C 12 H 15 ) N_2O_3PS. It has a strong contact and stomach toxicity, low toxicity to higher animals (male rat oral lethal dose of 2170 mg / kg), has been widely used to control a variety of crop pests, including underground pests and storage pests .1984 - In 1985, we used ~ (14) - phoxim for seed dressing and spraying, studied the phoxim residue in spring wheat plants and soil, and determined the phoxim in the harvest of grain flour and wheat bran Residues, put forward phoxim in wheat application safety standards.
