摘　　要：明确了河南省芝麻主要病害——苗病、病毒病、茎点枯病和叶斑病的发生危害及田间流行动态;试验筛选出抗病品种,复方多菌灵防治苗病、茎点枯病、叶斑病和40％氧化乐果治蚜防病毒病。据此提出以抗病品种为基础,药剂防治为保证的防治策略,制定出多种病害综合防治技术。经多点试验及示范推广,防病增产效果显著。The major sesame diseases in Henan are damping-off, wilt, mosaic, charcoal rot and leaf spot diseases. The epidemiology of these diseases was described. Results of identification showed that Yuzhi 1 , Henan 1 and Jizhi 1 were sesame varieties resistant to the diseases. Seed treatment with carbendazim at 3 g/kg seeds performed best in controlling seedling diseases. Spraying with carbendazim in July and August was most effective for reducing incidence of charcoal rot and leaf spot, while spraying with omethoate in July was effective for controlling aphides and the mosaic disease. Application of all these measures in the same field was more effective for reducing these diseases and increasing yields.
