[目的]近年来浙江西部山区春播玉米粗缩病危害严重,缺少有效的防治手段。研究通过拌种的方法来控制玉米粗缩病的发生,对指导生产防控具有一定实际意义。[方法]分别在自然发病与接毒发病条件下,应用吡蚜酮不同用量拌种与应用丁硫克百威、吡虫啉拌种,观察不同拌种处理对玉米粗缩病的发病影响。[结果]应用吡蚜酮拌种可以明显减轻玉米粗缩病发病,发病程度可下降50%~70%,且效果优于丁硫克百威、吡虫啉。
[Objective] In recent years, spring maize sowing in western mountainous area of Zhejiang Province endangered seriously and lacked effective control measures. Studying the method of seed dressing to control the occurrence of maize rough shingles has some practical significance to guide the production prevention and control. [Method] In the natural onset and the incidence of poisoning, the application of pymetrozine with different dosages of seed dressing and application of carbosulfan and imidacloprid seed dressing to observe the effect of different seed dressing treatment on the incidence of corn rough contracting disease. [Result] The application of pymetrozine seed dressing could obviously reduce the incidence of maize rough contracting disease, the incidence of maize could be reduced by 50% ~ 70%, and the effect was better than that of metsulfuron - methyl and imidacloprid.
