【摘要】 选用42%戊唑·百菌清悬浮剂、25%吡唑醚菌酯乳油、20%烯肟·戊唑醇悬浮剂和48%苯甲·嘧菌酯悬浮剂等四种新型及复配型杀菌剂对香蕉叶斑病(香蕉褐缘灰斑病、香蕉灰纹病和香蕉煤纹病)进行田间防治效果试验,结果表明:25%吡唑醚菌酯乳油对防治三种叶斑病均表现最好,四次施药后15天的防效为50.76%～68.07%;其次是42%戊唑·百菌清悬浮剂;而48%苯甲·嘧菌酯悬浮剂和20%烯肟·戊唑醇悬浮剂的防效则相对较差,不推荐使用。更多还原

【Abstract】 The field trial was carried out to study the efficacy of 4 compound fungicides namely 42% tebuconazole·chlorothalonil SC, 25% pyraclostrobin EC, 20% fenaminstrobin·tebuconazole SC, 48% difenoconazole ·azoxystrobin SC on control of banana leaf spot disease(Sigatokaleafspotdiseases,gray leaf spot disease and coal and grain disease). The result showed that the control effect of pyraclostrobin EC was 50.76%～68.07%, and was remarkably higher than the control effect of tebuconazole·chlorothalonil SC, fenaminstrobin·tebuconazole SC and difenoconazole ·azoxystrobin SC,the tebuconazole·chlorothalonil SC was second,difenoconazole ·azoxystrobin SC and fenaminstrobin·tebuconazole SC had lower control effect.更多还原
