摘　　要：对巴蜀地区(原四川省)花生青枯病的发生、分布及防治对策作了调查研究,发现巴蜀地区有花生青枯病发生,发病面积3万hm2左右,约占全国发病面积的10%。明确了四川盆地南部的酸性土区是主要病区,其次是江河沿岸的老冲积黄壤和新冲积潮沙土区,尚未发现石灰性紫色土上有花生青枯病。试验证实硫酸铜、西力生、托布津等杀菌剂和2～3年轮作,对花生青枯病无防治作用,而选用抗病品种能有效遏制花生青枯病蔓延为害,并筛选出一批抗病品种用于生产。The occurrence,distribution and the control measures of blight in peanut in Sichuan and Chongqing were investigated.It was found that the total occurrence area of blight in peanut was 30 000 hm^2,10% of the total occurring area in China.The acid soil area in south of the Sichuan Basin was the major occurring area, the second was the old yellow alluvial soil and the new sandy alluvial soil.Until now,no blight was found to occur in the purple soil area.Experiments showed that it had no help to use fungicides such as cupric sulphate,thiophanate,and rotation cultivation in controlling blight in peanut while it was very helpful to select blight-resistant peanut varieties in controlling blight.Several blight-resistant varieties were selected and applied in production.
