| 摘 要： | 云南省耿马县是烟草根结线虫病发生的重灾区,为了摸清该县烟草根结线虫病的发病因素,2012年在全县病情普查的基础上,对勐撒、贺派、四排山等三个主要烟草种植乡病原线虫、寄主情况和环境条件进行了实地调查和综合分析。结果表明,病害发生率和严重程度都大大超过了往年;危害烟草的根结线虫种类主要为花生根结线虫和爪哇根结线虫;抗病品种缺乏、管理粗放和气候异常是近年来当地烟草根结线虫病爆发的主要原因。根据发病特点,提出了以农业防治为主的烟草根结线虫病应对措施。

| Abstract: | Tobacco root-knot nematode disease has caused severe damage in Geng- ma County, Yunnan Province. In order to identify the pathogenic factors of the tobac- co root-knot nematode disease in this county, the pathogenic nematodes, hosts and environment of tobacco fields in Mengsa, Hepai and Sipaishan 3 main tobacco-grow- ing towns in Gengma County were investigated and analyzed based on the local re- lated field survey on tobacco root-knot nematode disease in this county in 2012. The results showed the incidence and severity of the tobacco root-knot nematode disease were all higher than those of previous years. dominant pathogens of the tobacco root-knot The species identification showed the nematode disease were Meloidogyne arenaria and M. javanica in Gengma County. The lacking of disease-resistant culti- vars, poor management and climatic anomaly were the main causes of the tobacco root-knot nematode disease in Gengma. According to the occurrence characteristics of the disease, the agricultural prevention-based control measures were proposed. |
