摘　　要：2009～2010年通过田间小区方法进行了6种杀菌剂防治马铃薯早疫病（Alternaria solani）的试验。结果表明：75%拿敌稳水分散性粒剂6 000倍、50%肟菌酯水分散性粒剂4 000倍、43%好力克悬浮剂3 000倍、25%阿米西达悬浮剂1 200倍效果均比较好,防效在82.0%～84.3%之间,70%安泰生可湿性粉剂400倍次之,防效75.9%～76.0%;80%代森锰锌500倍再次之,防效66.2%~66.8%。以上6种杀菌剂均可作为防治马铃薯早疫病的有效药剂应用。Six Fungicides were tested in field plot experiments during the years of 2009-2010 to control the potato early blight. The results indicated that Nativo 75% WG 6 000 times, Flint 50% WG 4 000 times, Horizon 43% SC 3 000 times, and Amister 25% SC 1 200 times were all effective. Their control effects ranged from 82.0% to 84.3%. Antracol 70% WP 400 times was next with the control effect 75.9%-76.0%, followed by Mancozeb 80% WP 500 times with 66.2%-66.8%. All of the six fungicides tested could be used to control potato early blight in production field.
