摘要 通过对病害的症状观察和病原鉴定查明,河南省小麦发生了一种新病害,就是由禾谷孢囊线虫(Heterodera avenae Wollenweber)引起的小麦泡囊线虫病.经人工接种测定,该线虫还可侵染大麦、燕麦和黑麦;在谷子、玉米、水稻和高粱上未见表现症状,根部也未查到线虫.田间药剂防治试验结果表明,小麦播种时沟施涕灭威或呋喃丹对该病有较好的防治效果.鉴定了河南省12个主要小麦品种的抗性,结果均不抗抱囊线虫病,但感病程度存在一定差异. Through observing the symptoms and identifing the pathogen,it was cleared that the new wheat disease occured in Henan Province was caused by cereal cyst nematode (Het-erodera avenue Wollenweber). The results of artificial inoculation test showed that this kind of cyst nematode could also infect barley, avena and rye, but corn, rice, sorghum and millet didn't express symptoms,and the nematode wasn't found even in their roots. The result of experiment conducted in the field indicated that furrow application of aldicarb or carbofuran at the same time of sowing could express a satisfying effect. None of 12 main cultivars of wheat in Henan province are resistant to the disease. But their susceptibility to the disease is different.
