Experimental study on the effect of different pesticides on wheat scab control
In order to screen for suitable pesticides for the prevention and control of wheat scab,this experiment selected six pesticides:40％propiconazole·tebuconazole suspension emulsion(Ti),43％tebuconazole suspension(T2),30％oxime bacteria·tebuconazole suspension(T3),200 g/L fluconazole hydroxylamine suspension(T4),30％propiconazole dispersible oil suspension(T5),and 25％cyanobacterium ester suspension(T6).The control(CK)was not sprayed,and the flight control effect of wheat scab was studied at the most suitable concentration in the instructions.The results showed that all six pesticides had no effect on the safety of wheat growth and could control the occurrence of wheat scab and reduce the impact of wheat scab on yield.Among them,the 43％tebuconazole suspension agent treatment(T2)had the highest effect on wheat disease control,with 90.04％and 94.94％,respectively.The yield increased by 63.15％compared to the control,and the comprehensive performance was the best.It can be applied in the prevention and control of wheat scab in the Jianghuai region.
