【摘要】 为了筛选出可以有效防治番茄青枯病的药剂以期为该病害的防治提供技术支持,本研究采用茎叶喷雾法和灌根法评价了5种杀菌剂对番茄青枯病的田间药效。田间试验结果表明,采用灌根处理时5种杀菌剂的防效优于茎叶喷雾处理,其中以40%春雷·噻唑锌SC800倍灌根处理防效最高,末次药后7d为86.5%,显著优于其他处理;末次药后14 d为88.21%,极显著优于其他处理,说明40%春雷·噻唑锌SC是防治番茄青枯病的理想药剂。更多还原

【Abstract】 In order to screen out effective control agents for tomato bacterial wilt, the field efficacy of 5 fungicides was tested by spraying and root irrigation method. The results showed that the efficacy of five fungicides by root irrigation treatment was better than that by spray treatment; and 800 times dilution of kasugamycin·zinc thiazole 40% SC had the highest efficacy(86.5%) on the 7 th day and(88.21%) on the 14 th day after the last root irrigation, which was significant better than other treatments, and proved that it was the ideal agent to control tomato bacterial wilt.更多还原
