摘要
马铃薯早疫病(Alternaria solani)是重庆早市菜用马铃薯上的最主要病害。本研究选取生产中应用较广泛的7种药剂,在地膜覆盖栽培模式下筛选具有较好防控效果的药剂。结果表明:500 g/L氟啶胺悬浮剂1200倍,250 g/L嘧菌酯悬浮剂1 000倍效果较好,第2次施药后10 d防效分别为83.41%,82.01%,明显高于当地常用药剂代森锰锌。因此,可以在大面积生产上使用。
Alternaria solaniis the most devastating disease of table potatoes grown for early market. In this research, seven widely used fungicides were tested under plastic mulching cultivation mode for screening the fungicide with good control efficacy. The results indicated that Fluazinam 500 g/L SC diluted 1 200 times and Azoxystrobin 250 g/L SC diluted 1 000 times had obvious control efficacy and were better than Mancozeb 80% WP diluted 600 times, the most common used fungicide. The control effects for the two fungicides 10 days after the second application were 83.41% and 82.01%, respectively. They should be recommended for use in potato production.
