摘要
In order to achieve ideal prevention and treatment effect of maize sheath blight,24%Jinggangmycin A+0.5%adjuvant,24%Jinggangmycin A,Bacillus subtilis and Jinggangmycin+B.subtilis were selected.Each agent was prepared into a 500 times dilution,and the control effect was tested by two times of spray application.The results showed that the disease index of maize sheath blight could be reduced by all the treatments,which were significantly different from that of the control group,but the differences between the treatments were not significant.Jinggangmycin+B.subtilis and B.subtilis had the best control effects.Therefore,their use for preventing maize sheath blight could reduce chemical residues of maize,and avoid environmental pollution.
