通过田间观察及调查，明确了云南干热区4个木薯品种叶斑病在4种不同种植模式下的发生及危害情况，得出叶斑病的发病率和危害指数。对木薯品种和栽培模式等主要影响因子的单因子分析和多重比较结果表明：SC5和新选048采用直插并施肥的方式发病率最低，新选048采用直插的方式发病程度最轻。

A new leaf spot disease of cassava was first found during a survey made from 2008 and 2009 in cassava main growing regions, include Yunnan. It is caused by B.setaria. On the basis of some results acquired from observation and investigation in field, the article has clearly determined the incidence and hazards index of leaf spot for four different cassavas in Yunnan hot-dry area. The major influence factors were analyzed by single or Duncan test. It reveals that the incidence of SC5 and 048 are the lowest when they are erected and fertilize, the disease index is the lowest when it is erected.
