玉米粗缩病在侵染循环中越冬寄主种类少，初侵染来源少，且地理分布不均匀，传病途径单一，侵染时间短。利用这些薄弱环节，调整作物和品种的生产布局，适时晚播，包括夏病秋治在内的及时防治灰飞虱，加强水肥管理，进行生态、农业和药剂防治，切断其侵染循环中的链条，就能控制玉米粗缩病的危害。 In the infection cycle, maize coarse-wintering hosts have fewer winter winged species, less primary infection and less uniform geographic distribution, single pathways of infection and short infection time. We will use these weaknesses to adjust the production layout of crops and breeds, timely and late-onset broadcasts, including timely control of Laodelphax striatellus, control of water and fertilizers, ecological, agricultural and pharmaceutical control, cutting off the infection cycle Chain, you can control the dangers of corn sickening.
