摘要
红波罗花为一种野生高山花卉,具有较高的观赏价值。在引种驯化过程中有褐斑病发生,通过3年观察发现:褐斑病6月中旬开始发病,7月初至9月中旬为盛发期,连作重茬、过量施氮肥均可加重该病发生。侵害叶片、果荚,严重影响植株的开花和结实,给开发利用造成严重的障碍。病原鉴定为广生亚大茎点菌(Macrophom i-na phaseolina),由于红波罗花是野生高山花卉引种栽培,该病害国内外未见报道。
One new fungal disease, Incarvillea delavayi leaf spots, is reported in this paper. This is the first report in world of leaf spots of Incarvillea delavayi caused by Macrophomina phaseolina description and illustration for the new disease record are provided. The severe disease occurred usually during spring, the beginning of summer and the end the autumn, especially in rainy season, and be aggravated by continuous cropping and more nitrogenous fertilizer.
