Absrta ct [Objective ] To select ideal biological pesticides to control virus diseases of autumn tomato in greenhouse .[ Method] By using meth-ods of forecasting, randomized block design and statistical analysis, the control effects of two biological pesticides of lentinan +gibberellin-heter-oauxin-brassinolide (GHB) and ningnanmycin +GHB on virus diseases of autumn tomato in greenhouse was studied .[Result] When the virus diseases of autumn tomato in greenhouse were serious, 0.5% lentinan AS 3 000 mL/hm2 +GHB WP 600 g/hm2 and 8% ningnanmycin AS 900 mL/hm2 +GHB WP 600 g/hm2 were applied for 4 times, once in 7 d, and the control effects on the 10th , 17th, 26th and 35th day were above 88%, 87%, 78%and 67%respectively.The difference between the two biological pesticides was not significant , while the control effect of len-tinan +GHB was significantly higher than that of moroxydine hydrochloride (CK) +GHB, and the control effect of ningnanmycin +GHB was significantly higher than that of moroxydine hydrochloride +GHB.[Conclusion] Lentinan +GHB and ningnanmycin +GHB are the ideal bio-logical pesticides for the control of virus diseases of autumn tomato as well as pollution-free, green and organic agricultural products.%[目的]筛选温室秋番茄病毒病的生物农药。[方法]采用测报调查、随机区组设计和统计分析等方法，研究生物农药香菇多糖＋赤·吲乙·芸苔（碧护）和宁南霉素＋赤·吲乙·芸苔防治番茄病毒病的效果。[结果]在温室大棚秋季番茄病毒病发生较重情况下，施用0．5％香菇多糖水剂3000 mL／hm2＋碧护可湿性粉剂600 g／hm2、8％宁南霉素水剂900 mL／hm2＋碧护可湿性粉剂600 g／hm2，7 d施药1次，连续施用4次，药后10、17、26、35 d防治效果均在88％、87％、78％和67％以上，且两药剂防治效果差异不显著，香菇多糖＋碧护极显著高于盐酸吗啉胍（对照药剂）＋碧护，宁南霉素＋碧护显著高于盐酸吗啉胍＋碧护。[结论]香菇多糖＋碧护和宁南霉素＋碧护不仅可以作为防治病毒病的理想药剂，而且可以作为现代农业示范区、无公害农产品、绿色农产品和有机农产品防治病毒病的理想药剂。
