Evaluation of the Field Application Effects of Mixed Coating Treatment of Microbial Agent and Chemical Agent on Wheat
To evaluate the efficacy of mixed coating treatment of 200 billion CFU/g of Bacillus poly-myxa WDG(KN-03)and 23%imidacloprid·rotonitrile·phenylethicazole FSC(23%IRP)against wheat sheath blight,as well as the effects on seedling growth and yield,providing basis for the pro-motion and application of combined microbial and chemicals.The field trials were carried out by seed-coating at Boai and Wenxian.The results showed that the combined coating treatment of KN-03 and 23%IRP benefited seedling growth and yield of wheat,and showed excellent control effect(disease rate of 12.3%-15.5%)on wheat sheath blight over single 23%IRP(disease rate of 41.8%-50%)and other agent coating treatment(disease rate of 28.4%-41.3%).The combined coating treatment of KN-03 and 23%IRP had good control effect on wheat sheath blight and contributes to high yield.
