防治蚕豆赤斑病的药剂筛选研究

Research on Screening of Fungicides Against Botrytis fabae

为了筛选有效防治蚕豆赤斑病的药剂,2012年在江苏沿江地区农业科学研究所进行了药剂筛选田间试验。结果表明:80%代森锰锌可湿性粉剂、60%唑醚.代森联水分散粒剂对蚕豆赤斑病的防治效果为80.88%～89.26%,增产率为10.85%～41.73%,均优于对照药剂50%多菌灵可湿性粉剂,具有明显的防病和增产效果,应用前景良好。

In order to select effective fungicides for controlling Botrytisfabae, the field experiments were carded out in Jiangsu Yanjiang area agricultural science research institute in 2012. The results showed that the control effects of mancozeb 80% WP and pyraclostrobin ＋ metiram 60% WG against Botrytisfabae were 80.88%-89.26%, and the yield increasing rates were 10.85%-41.73%. Mancozeb 80% WP and pyraclostrobin ＋ metiram 60% WG should have beautiful prospect against Botrytisfabae owing to excellent control effect and increase yield.
