百菌清(Chlorothalonile,又称Daconil),化学名称为2,4,5,6-四氯-1,3,一间苯二腈(tetra-chloroisophthalonitrile),分子式为C_8Cl_4N_2,分子量265.9。1962年由美国Diamond Sharmrock Che-mical Company合成。我国自1975年开始实验性合成,1982年投产。百菌清能有效地防治蔬菜、果树、茶叶、热带作物等的多种霉菌病,尚可用于皮革、木材、水果的防霉、保鲜。它可阻止致病霉菌孢子发 Chlorothalonile (also known as Daconil), the chemical name is 2,4,5,6-tetrachloro-1,3, a phthalonitrile (tetra-chloroisophthalonitrile), molecular formula C_8Cl_4N_2, molecular weight 265.9 by United States Diamond Sharmrock Che-mical Company synthesis. Since 1975, China began experimental synthesis, put into operation in 1982. Chlorothalonilum can effectively prevent and cure many mycotic diseases such as vegetables, fruit trees, tea leaves and tropical crops, and can still be used for mildew prevention and preservation of leather, wood and fruits. It prevents pathogenic mold spores
