Effect of Bacillus amyloliquefacien Mixed with Other Agents on Wheat Crown Rot Disease and Yield
In order to explore the effective control methods for wheat crown rot,Bacillus amyloliquefacien(≥100 million cfu/g)AS,5％mepiquat chloride AS and thifluzamide(240g/L)SC were selected to control the disease in this study.The results showed that the combination of the three agents increased the four evaluation indexes and reduced diseased plants in seeding stage.The combinations also significantly reduced the incidence speed in jointing stage,the treatment 6 was the best and the diseased stem rate was 20.00％.The results of the survey during the seed filling stage showed that the three combinations could control the spread of wheat crown rot and the diseased stem rate was 23.33％-24.44％,the control efficiency was more than 75％.The combinations of the three agents increased the yield rate by more than 21.23％.The result showed that the combinations of the three agents could control the wheat crown rot and increase the wheat yield,which could be popularized in the future.
