摘要
为筛选防治玫瑰白粉病的有效药剂,2017年开展大田防治试验。结果表明,10%苯醚菌酯SC 66.67 mg/L和250 g/L嘧菌酯SC 166.67 mg/L处理对玫瑰白粉病防治效果良好,且具有显著增产效果。药后14 d,两者防效分别为94.56%、92.12%,产量分别为2 256 kg/hm^2、2 243 kg/hm^2,增产率分别为172.79%、171.22%。苯醚菌酯是防治食用玫瑰白粉病的有效药剂,其宜在白粉病发生初期施用,7 d后再喷施1次。为延缓抗性发生,苯醚菌酯可与嘧菌酯、己唑醇、腈菌唑等交替使用。
In order to screen effective fungicides for controlling Sphaerotheca pannsa (Wallr.) Lev, field trial was carried out in 2017. The results showed that ZJ0712 10% SC 66.67 mg/L and azoxystrobin 250 g/L SC 166.67 mg/L could control Sphaerotheca pannsa (Wallr.) Lev effectively, with the control effects of 94.56% and 92.12% on the 14th day after spraying, and the productions of 2 256 kg/hm2 and 2 243 kg/hm2, the increase rates of 172.79% and 172.12%. ZJ0712 was an effective fungicide against Sphaerotheca pannsa (Wallr.) Lev. And it could properly alternate with azoxystrobin, hexaconazole and myclobutanil.
