摘要
[目的]采用不同药剂防治忍冬白粉病,筛选最适宜的药剂.[方法]对患病的忍冬植株使用不同药剂喷雾处理,分别在药后7和14 d进行调查,计算发病率、病情指数和防治效果.[结果]药后7 d,10%苯醚甲环唑水分散粒剂6000倍稀释液、25%戊唑醇可湿性粉剂1200倍稀释液、30%己唑醇悬浮剂2500倍稀释液均有防治效果,但无极显著差异.药后14 d,25%戊唑醇可湿性粉剂1200倍稀释液的防治效果最好,达76.10%.[结论]25%戊唑醇可湿性粉剂1200倍稀释液的防治效果最好,10%苯醚甲环唑水分散粒剂6000倍稀释液的防效次之,30%己唑醇悬浮剂2500倍稀释液几乎没有防效.25%戊唑醇可湿性粉剂可以作为忍冬白粉病的防治用药.
Abstract
[Objective] The aim was to use different fungicides to control powdery mildew of Lonicera japonica Thunb.and screen the most ap-propriate fungicide.[ Method] The diseased honeysuckle plants were treated with different agents, and were investigated at 7 and 14 days after the fungicide,then to calculate the morbidity, disease index and control effect.[ Result] 10% difenoconazole WG diluted to 6000 times, 25% tebuconazole WP diluted to 1200 times and 30%hexaconazole SC diluted to 2500 times had abvious control effects after 7 days, without significant differences at 0.01 level.25% tebuconazole WP diluted to 1200 times exhibited the best control effect after 14 days, achieved 76.10%.[ Conclusion] 25% tebuconazole WP diluted to 1200 times exhibited the best control effect, 10% difenoconazole WG diluted to 6000 times was ranked second, 30% hexaconazole SC diluted to 2500 times almost had no control effect.25% tebuconazole WP can be used as a control fungicide for powdery mildew of Lonicera japonica Thunb..
