三种杀菌剂对灰葡萄孢菌的毒力测定

采用培养皿滤纸抑菌圈法，测定三种杀菌剂（利得，克露，速克灵）不同浓度对灰葡萄孢菌的抑菌能力。结果表明：三种杀菌浓度在５１２０ｍｇ／Ｌ时，对灰葡萄孢菌的抑制率利得为７１．３３％，速克灵为５９．６７％，克露为３４．６７％，２０ｍｇ／Ｌ时三种药物的抑菌平均为零。抑菌效果以利得最高，是速克灵的１．１２倍，克露的２．８５倍。

Experimenting of Poison Strength to Batrytis Cinerea with Three Types of Bactericide

Experimenting the inhibition degree of bacteriostasis to batrytis cinerea which is dete-mined with three types of bactericide (lide, curzate and Sumilex)of different consistency by adopting and cultivating filter paper detection of inhibition zone/The result shows that poison strength to Batrytis Cine-rea with three types of Bactericide: when the consistency of the three types of bactercide is 5120mg/L, the inhibition degree of lide is 71.33 percent, Sumilex is 59.67 percent and curzate is 34.67 percent; When the consistency is 20mg/L,the inhibition degree of three types of bactercide is zero. Lide s result is the best; It is 1.12 times higher than sumilex and 2.85 times higher than curzate.
