摘要
针对玉米大斑病发病后期植株高大防治困难的问题,在黑龙江省黑河市进行了玉米大斑病早期预防试验。结果表明:在玉米大喇叭口期,使用杀菌剂苯甲·嘧菌酯和苯甲·丙环唑采用机械喷雾的方式进行防治,可以有效降低玉米大斑病发病率、发病级别、病情指数和病斑大小,进而减轻大斑病的危害程度,减少产量损失。
The early prevention test of leaf blight was made for difficult problems of maize leaf blight prevention in Heihe city in Heilongjiang province. The results showed that at the huge bellbottom period, spraying fungicides benzoic azoxystrobin and propiconazole benzoic could effectively reduce the incidence and level of maize leaf blight, the disease index and lesion size, thereby reduce harmful levels of leaf blight and reduce yield losses.
