水稻种子播种前用甲基托布津或三环唑浸种消毒,可以减少颖枯病菌初次侵染源,在水稻剑叶抽出期用甲基托布津、三环唑或灭病威叶面喷施均可显著降低颖枯病病情指数,提高水稻结实率、千粒重和稻谷产量。在同等栽培条件下,水稻品种间或杂交稻组合间感染颖枯病程度差异甚大,选育和推广抗病品种是防治颖枯病的有效措施之一。
Before sowing rice seeds with thiophanate-methyl or tricyclazole seed soaking disinfection can reduce the initial source of R. solani pathogens in rice flag leaves with methyl thiophanate, tricyclazole, It can significantly reduce the disease index of WP and improve the seed setting rate, 1000-grain weight and rice yield. Under the same cultivation conditions, there are great differences in the prevalence of WPB among rice cultivars or hybrid rice combinations. Breeding and popularizing of resistant varieties is one of the effective measures to control WPB.
