摘　　要：为了保护生态环境和提高果品质量安全,作者在甘肃省天祝县温室栽培条件下研究4种草原有毒植物狼毒、熏倒牛、互叶醉鱼草和醉马草粗提液对葡萄常见病虫害霜霉病、白粉病、灰霉病和短须螨、桃蚜、白粉虱防治效果的影响。结果表明,喷施狼毒、熏倒牛、互叶醉鱼草和醉马草粗提液后均极显著降低霜霉病、白粉病、灰霉病的病斑数和病斑直径,降低短须螨、桃蚜、白粉虱的虫口密度。但不同粗提液的防治效果差异较大,狼毒粗提液对霜霉病的防治效果最好,熏倒牛对白粉病的防治效果最好,互叶醉鱼草对灰霉病的防治效果最好。狼毒和互叶醉鱼草粗提液均能彻底杀灭短须螨、桃蚜、白粉虱,虫口密度为0。In order to protect ecological environment and increase health safety quality of fruits,we studied the effects of 4 crude extracts from poisonous plants Stellera L.,Biebersteinia heterostemon Maxim.,Buddieja alternifolia Maxim.,Achnatherum inebrians(Hance)Keng on grassland on control effects of downy mildew,powdery mildew,gray mold and spider mites,peach aphids,white flies.The result showed that the disease spot number and diameter of downy mildew,powdery mildew,gray mold were decreased,the pest density of spider mites,peach aphids,white flies were decreased.The difference of control effects among different crude extracts were higher,the crude extract from Stellera L.on control effects of downy mildew was the best in all crude extracts,the crude extract from Biebersteinia heterostemon Maxim.on control effects of powdery mildew was the best,the crude extract from Buddieja alternifolia Maxim.on control effects of gray mold was the best,the crude extracts from Stellera L.and Buddieja alternifolia Maxim.can killed drastically spider mites,peach aphids,white flies,the pest density was 0.
