摘要: 【目的】探究枯草芽孢杆菌Tpb55和棘孢木霉HG1复合菌水分散粒剂对烟草黑胫病和赤星病的防治效果。【方法】采用单因素试验筛选并优化枯草芽孢杆菌Tpb55和棘孢木霉HG1复合菌水分散粒剂的助剂,通过盆栽试验和田间试验分别验证复合菌水分散粒剂400、800和1 200倍液对烟草黑胫病和赤星病的防治效果。【结果】对助剂的用量进行优化,确定复合菌水分散粒剂的最优配方为5%湿润剂(皂角粉)、6%分散剂(羧甲基纤维素钠)、3%黏结剂(聚乙二醇6000)、5%崩解剂(羧甲基淀粉钠),载体硅藻土补充至100%。枯草芽孢杆菌Tpb55和棘孢木霉HG1复合菌水分散粒剂400倍液效果最优,对烟草黑胫病的室内防治效果为81.53%、对烟草赤星病的田间防治效果为70.93%。【结论】确定了枯草芽孢杆菌Tpb55和棘孢木霉HG1复合菌水分散粒剂的最优配方,且复合菌水分散粒剂400倍液对烟草黑胫病和赤星病具有良好的生防效果。

Abstract: 【Objective】To investigate the control efficacy of Bacillus subtilis Tpb55 and Trichoderma asperellum HG1 compound bacteria water dispersible granules on tobacco black shank and tobacco brown spot. 【Methods】Single-factor experiments were conducted to screen and optimize the adjuvants for B. subtilis Tpb55 and T. asperellum HG1 compound bacteria water dispersible granules. Pot and field experiments were carried out to evaluate the control efficacy of the compound bacteria water dispersible granules at 400-fold,800-fold,and 1 200-fold dilutions on tobacco black shank and tobacco brown spot,respectively.【Results】By optimizing the dosage of adjuvants,the optimal formula of the compound bacteria water dispersible granules was determined as follows:5% wetting agent(saponin powder),6% dispersant(carboxymethylcellulose sodium),3% binder(polyethylene glycol 6000),5% disintegrant(sodium carboxymethyl starch),with diatomaceous earth as the carrier to make up 100%. The 400-fold dilution of B. subtilis Tpb55 and T. asperellum HG1 compound bacteria water dispersible granules exhibited the highest efficacy,achieving an indoor control efficacy of 81.53% on tobacco black shank and a field control efficacy of 70.93% on tobacco brown spot.【Conclusion】The optimal formula of B. subtilis Tpb55 and T. asperellum HG1 compound bacteria water dispersible granules are confirmed,and the 400-fold dilution of compound bacteria water dispersible granules exhibits excellent biocontrol efficacy on tobacco black shank and tobacco brown spot.
