摘要：

为有效防治香蕉叶斑病,筛选具有较好防治效果的杀菌剂。笔者以400 g/L氯氟醚菌唑·吡唑醚菌酯为试验药剂,在2018年和2019年开展了防治香蕉叶斑病的田间药效试验。试验表明,在香蕉叶斑病发病初期进行茎叶喷雾施药,133.3 mg/kg的试验药剂在3次药后的平均防效在2018年和2019年分别为74.08%和74.54%,明显优于对照药剂中133.3 mg/kg的400 g/L氯氟醚菌唑悬浮剂、166.7 mg/kg的吡唑醚菌酯乳油和丙环唑乳油;而200 mg/kg的400 g/L氯氟醚菌唑·吡唑醚菌酯悬浮剂在3次药后的平均防效可达79.68%和79.93%。说明400 g/L氯氟醚菌唑·吡唑醚菌酯悬浮剂对香蕉叶斑病的防治效果优良,是防治香蕉叶斑病的优良杀菌剂,值得在香蕉产区推广应用。

Abstract:

To effectively prevent and control banana leaf spot disease, and screen fungicides with good control efficacy, the authors conducted field trials against banana leaf spot disease in 2018 and 2019, using 400 g/L mefentrifluconazole·pyraclostrobin as a test agent. The stem-leaf spraying was carried out at the early stage of banana leaf spot disease, and the average control effect of 133.3 mg/kg of mefentrifluconazole·pyraclostrobin after 3 times was 74.08% and 74.54% in 2018 and 2019 year, respectively, which was significantly better than that of the 133.3 mg/kg of 400 g/L mefentrifluconazole, 166.7 mg/kg of pyraclostrobin and propiconazole in the control agent. And the average control effect of 200 mg/kg of 400 g/L mefentrifluconazole·pyraclostrobin after 3 times reached 79.68% and 79.93%. The results indicate that 400 g/L mefentrifluconazole·pyraclostrobin has a good effect on the prevention and treatment of banana leaf spot disease, and is an excellent fungicide for popularization and application in banana production areas.
