试验证实灰飞虱是玉米粗缩病的主要传播介体,玉米上以第一代灰飞虱带毒传病危害为主。小麦轻病株或隐症株可能是第一代灰飞虱的饲毒源。玉米苗期是否与第一代灰飞虱迁飞高峰期(小麦收割前后)相遇是病害发生轻重的决定性因子。病害一般为夏玉米重于春、秋玉米,套种田重于平种田,大麦茬重于小麦茬。适时防治介体并结合其他措施可有效控制该病的危害。
Test confirmed that Laodelphax striatellus is the main transmission medium of maize, the first generation of corn on the Laodelphax striatellus with the main hazards. Slightly ill or implicated wheat plants may be the first generation of Laodelphax striate. Maize seedling stage and the first generation of Laodelphaxillin (the wheat before and after harvest) is the decisive factor in the severity of the disease. Diseases are generally heavier than summer spring corn, autumn corn, sets of farming heavy than flat farming, barley stubble heavier than wheat stubble. Proper control of the mediator combined with other measures can effectively control the harm of the disease.
