7种药剂对枣缩果病病原菌——聚生小穴壳菌的抑制作用

Research on Function of Seven Germicides to Inhibit Pathogens of Fruit Shrink Disease in Jujube

为有效防治枣缩果病的发生发展,选用7种不同杀菌剂,对枣缩果病病原菌——聚生小穴壳菌进行了室内抑菌试验和田间药剂防治试验。结果表明:20.67%万兴乳油+68.75%易保可分散粒剂+72%链霉素可溶性粉剂组合、10%世高可分散粒剂+90%新植霉素可溶性粉剂组合、80%大生M-45可湿性粉剂的抑菌能力最强;其次为20.67%万兴乳油组合、10%世高可分散粒剂和85%枣病克星可湿性粉剂;4%绿盾农抗120水剂对两种病原菌的抑制作用不明显。

The author chose seven common germicides to inhibit jujube＇ s fruit shrink disease; in comparison with disinfected water,the fungistasis was done with Dothiorella gregaria Sacc. which is one kind of pathogens. The results showed 20. 67% oil sohble concentrate of Wanxing ＋ 68.75% dispersed granula of Yibao ＋ 72% sohble granula of streptomycin, 10% dispersed granula of Shigao ＋90% soluble granular of New Zhimeisu, and 80% sohble powder of Dasheng M -45 are the best choice to inhibit fungi; 20.67% oil soluble concentrate of Wanxing, 10% dispersed granula of Shigao and 85% soluble powder of Zaobingkexing are the Second choices; 4% agri - antibiotic 120 of Ludun is not very usuful in inhibiting that fungi.
