玉米斑病是我省玉米上的主要病害之一。近年来,春播玉米面积的扩大,有利于玉米斑病的发生,致使发病提早,有些地区发病较重,对玉米生产带来较大的影响。这几年,由于我们采取了选育抗病品种和改进栽培技术等综合防治措施,收到了一定的效果。同时,在唐山、吉林二化工所的指导与支持下,进行了新药剂防治玉米斑病试验工作。现将药剂防治试验总结如下。
Corn streak is one of the main diseases on corn in our province. In recent years, the expansion of corn sowing in spring is conducive to the occurrence of corn leaf spot, leading to an earlier onset of disease and heavier incidence in some areas, which has a greater impact on corn production. In recent years, we have achieved certain results as we have taken comprehensive prevention and control measures such as breeding resistant varieties and improving cultivation techniques. At the same time, under the guidance and support of Tangshan Chemical Industry Co., Ltd. and Jilin Chemical Industry Co., Ltd., the pilot work on new chemical agents against corn germ was conducted. Now pharmaceutical control trials are summarized below.
