经多次采样鉴定，安徽怀远县红麻上的根结线虫为南方根结线虫（Ｍｅｌｏｉｄｏｇｙｎｅｉｎｃｏｇｎｉｔａ）１号小种和２号小种，未发现长江流域和华南麻区普遍存在的爪哇根结线虫（Ｍ．ｊａｖａｎｉｃａ）。新发现木薯和甘蔗是对红麻上根结线虫免疫的作物，以其和红麻轮作，有很明显的防病增产作用。筛选出了辛拌磷和托福灵两种新型农药，前者优于广泛施用的杀线虫剂涕灭威，后者对红麻炭疽病防效明显，保苗效果突出。Ｂｔ乳剂是对小造桥虫有效的生防制剂。文中对组建红麻病虫害综防体系作了讨论。
After multiple sampling and identification, the root knot nematode on kenaf in Huaiyuan County of Anhui Province was Meloidogyne incognita races 1 and 2, and no common root knot nematode (Meloidogyne incognita) was found in the Yangtze River valley and South China. M.javanica). The newly discovered cassava and sugar cane are the crops that are immune to root knot nematode on kenaf. With its rotation with kenaf, there is a clear effect of disease prevention and yield increase. Two new pesticides, phoxim and tobramycin, were screened out. The former is better than the other widely used nematicide aldicarb. The latter has obvious anti-anthracnose control effect and prominent seedling protection effect. Bt emulsion is a potent biocontrol agent for Trichinella spiralis. The article discusses the establishment of kenaf system.
