代森锰锌是沈阳化工研究院农药安评中心60年代由美国 Rohm and Hass 公司研制的新的有机硫杀菌剂,原药为灰黄色粉末。代森锰锌对大白鼠口服急性中毒 LD_(50)为8000毫克/公斤,对敏感性人员的皮肤有刺激性。代森锰锌是用于许多叶部病害的保护性杀菌剂,对小麦锈病、稻瘟病、玉米大斑病、蔬菜霜霉病、疫病及果树黑星病、赤星病、炭疽病等都有很好的防治效果。国外代森锰锌在作物中的残留分析法颇多,Cullen,T.E.和 Reppel,C.E.用分光光度法测定了蔬菜和水果中经酸解代森锰锌释放出的二硫化碳。Ninvenson,A.应用高压液体色谱法测定了莴苣中的代森锰锌残留量。Mecully,K.A.应用顶空色谱技术测
Mancozeb is Shenyang Institute of Chemical Pesticide Safety Assessment Center 60 years by the United States Rohm and Hass company developed a new organic sulfur fungicide, the original drug is a greyish yellow powder. Mancozeb oral acute poisoning LD_ (50) in mice is 8000 mg / kg, irritating to the skin of sensitive individuals. Mancozeb is a protective fungicide that is used in many leaf diseases and has a strong protective effect on wheat rust, blast, maculote corn, vegetable downy mildew, blight and fruit tree scab, brown spot disease, anthrax, etc. Good control effect. Abroad, mancozeb residues in the analysis of a large number of crops, Cullen, T.E. and Reppel, C.E. spectrophotometric determination of vegetables and fruits by the acid solution of mancozeb released carbon disulfide.
