| 中文摘要: |
| 为筛选防治香蕉采后炭疽病的新型防腐保鲜药剂, 2015年和2016年连续两年进行了复配药剂32%吡唑醚菌酯·二氰蒽醌水分散粒剂防治香蕉炭疽病的采后保鲜试验, 对该药剂防治香蕉炭疽病的效果及安全性进行了评价。试验结果表明:32%吡唑醚菌酯·二氰蒽醌水分散粒剂有效成分用量640 mg/kg对香蕉炭疽病具有较好的防治效果, 2015年药剂处理后12 d的防治效果为81.80%, 2016年药剂处理后6 d的防治效果为83.36%, 显著优于对照药剂22.7%二氰蒽醌悬浮剂500 mg/kg处理, 与对照药剂250 g/L吡唑醚菌酯乳油500 mg/kg的处理防效相 当。32%吡唑醚菌酯·二氰蒽醌水分散粒剂对香蕉果实安全, 蕉果催熟后, 果实颜色金黄, 风味正常, 值得推广应用于香蕉果实的采后保鲜贮运。 |
| 英文摘要: |
| In order to screen a new preservative agent against post-harvest anthracnose disease for preservation of banana, a two-year consecutive experiment of pyraclostrobin·dithianon 32% WG was conducted to evaluate its efficacy and safety on controlling the post-harvest anthracnose of banana. The results showed that pyraclostrobin·dithianon 32% WG at 640 mg/kg had a good control effect on banana anthracnose, with the efficacies of 81.80% 12 days after fungicide treatment in 2015 was and 83.36% 6 days after treatment in 2016, which was significantly better than that of dithianon 22.7% SC at 500 mg/kg and equivalent to that of pyraclostrobin 250 g/L EC at 500 mg/kg. Pyraclostrobin·dithianon 32% WG was safe for banana fruits. After ripened banana fruits, the fruits were golden in color and normal in flavor. It is worth promoting the application of this preservative agent in post-harvest storage and transportation of banana fruits. |
