摘　　要：为减轻番茄病毒病的发生危害,减少化学农药用量、残留和环境污染,该文采用测报调查、随机区组设计和统计分析等方法,开展了生物农药香菇多糖+赤·吲乙·芸薹(碧护)和宁南霉素+赤·吲乙·芸薹防治番茄病毒病田间药效试验。结果表明:在温室大棚秋季番茄病毒病发生较重情况下,每667m2用0.5%香菇多糖水剂200m L+碧护可湿性粉剂40g、8%宁南霉素水剂60m L+碧护可湿性粉剂40g,7d施药1次,连续施用4次,药后10、17、26、35d,防治效果均在88%、87%、78%和67%以上,且2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。因此,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。In order to alleviate the damage of tomato virus diseases, reduce chemical pesticide consumption and resi- due, and prevent environmental pollution, the methods of forecasting, randomized block design and statistical analysis were used in field efficacy tests of two biological pesticides of Lentinan ＋gibberellin - heteroauxin - brassinolide （GHB） and Ningnanmycin ＋GHB. The results showed that, when the autumn tomato virus disease was serious, 0.5% Lentinan AS 200mL ＋GHB WP 40g and 8% Ningnanmycin AS 60mL ＋GHB WP40g per 667m^2 were applied for 4 times,once in 7 days, and the control effects on the 10th , 17th ,26th and 35th day were above 88%, 87%, 78% and 67%. The difference between the two biological pesticides was not signitiicant, while the control effect of Lentinan ＋GHB was significantly higher than that ofmoroxydine hydrochloride （CK）＋GHB, and the control effect of Ningnanmycin ＋ GHB was significantly higher than that ofmoroxydine hydrochloride ＋ GHB.These results indicated that Lentinan ＋GHB and Ningnanmycin＋GHB were the ideal biological pesticides, which could be used not only controlling tomato virus diseases, but also for realizing modem, pollution-frce, green and organic agricultural production.
