摘要
[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3 000 m L/hm^2+碧护可湿性粉剂600 g/hm^2、8%宁南霉素水剂900 m L/hm^2+碧护可湿性粉剂600 g/hm^2,7 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。
[Objective]To select ideal biological pesticides to control virus diseases of autumn tomato in greenhouse. [Method]By using methods of forecasting,randomized block design and statistical analysis,the control effects of two biological pesticides of lentinan + gibberellin-heteroauxin-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 m L / hm^2+ GHB WP 600 g / hm^2 and 8% ningnanmycin AS 900 m L / hm^2+ GHB WP 600 g / hm^2 were applied for 4 times,once in 7 d,and the control effects on the 10 th,17th,26 thand 35thday were above88%,87%,78% and 67% respectively. The difference between the two biological pesticides was not significant,while the control effect of lentinan + 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 biological pesticides for the control of virus diseases of autumn tomato as well as pollution-free,green and organic agricultural products.
