摘要
香蕉尾孢菌叶斑病是香蕉上的重要病害,每年夏秋季节在华南蕉区普遍发生,危害严重。2003 ̄2004年进行新型杀菌剂50%醚菌酯干悬浮剂对香蕉尾孢菌的毒力测定和防治叶斑病药效试验,结果表明,50%醚菌酯干悬浮剂对香蕉尾孢菌的抑菌效果明显,对香蕉叶斑病有良好的防治效果,对香蕉安全;第3次施药后15 d,50%醚菌酯干悬浮剂1 500倍的防治效果达到82.67%,显著优于对照药剂25%敌力脱乳油1 500倍的防效,建议在生产上推广使用。
Sigatoka disease of banana is the main disease of banana, the disease mainly occurs at 6-11 months in South China. 50% kresoxim-methyl DF is a new fungicide,which shows specifically high activity against Cercospora musae and sigatoka disease of banana. During 2003-2004, the result of tests in fields showed that 50% kresoxim-methyl DF using 1:1 500 for three times after 15 days gave a control effect of 82.67% against sigatoka disease of banana. These results demonstrated that 50% kresoxim-rnethyl DF had a better control effect against sigatoka disease of banana than 25%Tih EC (1:1 500), and it was worthy to be popularized on the growing practice.
