摘　　要：试验主要通过对5种不同药剂交替施用方法防治马铃薯晚疫病的效果进行了研究。结果表明:5种药剂交替施用对马铃薯晚疫病的防效均显著。其中70%安泰生可湿性粉剂、64%杀毒矾可湿性粉剂、72%杜邦克露可湿性粉剂交替施用效果最佳,防效达75.1%,增产66.37%;其次分别为70%安泰生可湿性粉剂、58%宝大森可湿性粉剂、72%杜邦克露可湿性粉剂;70%安泰生可湿性粉剂、58%宝大森可湿性粉剂、64%杀毒矾可湿性粉剂;70%代森锰锌可湿性粉剂、58%宝大森可湿性粉剂、72%杜邦克露可湿性粉剂交替施用,防效分别为71.7%、68.2%、62.1%,增产分别为57.70%、52.87%、43.43%。This experiment researches the effect of preventing and controlling potato late blight through the ahemating application of five different fungicides. The results show that five kinds of fungicides ahemating application affect the potato late blight control significantly. Among which, 70% Aetna Health WP, 64% Antivirus Alum WP, and 72% Open Dubangke WP have the best alternative application effect, which can reach 75.1% control efficiency and an increase of 66.37%.The following is 70% Aetna Health WP, 58% Po-Sen WP, and 72% Open Dubangke WP; 70% Aetna Health WP, 58% Po-Sen WP, and 64% wettable powder antivirus alum; 70% Mancozeb moist powder, 58% Po-Sen WP, and 72% Open Dubangke WP alternating application, with the control efficiency of 71.7%, 68.2%, 62.1%, and an increase of 57.70%, 52.87%, 43.43%.
