[Objective]To seek an effective and safe medicament to control wheat scab,and to reduce the incidence rate of wheat scab and the effect of medicament itself on wheat yield and quality.[Method]We selected three types of fungicides(carbendazim)and plant immune inducers(ZNC,aminooligosaccharides)to investigate the inhibitory effects of different agents on the pathogen of wheat scab,Fusarium graminearum,using the plate inhibition method.Then we verified the effectiveness of different pesticides through pot experiments.Also we explored the effects of different pesticides on wheat growth through pot experiments,as well as the field control effects of different pesticides on wheat scab under artificial inoculation with F.graminearum.[Result]Carbendazim has a significant inhibitory effect on the growth of F.graminearum,and its field control effect is also significantly higher than that of ZNC and aminooligosaccharides,with a control effect of 77.90%.ZNC and aminooligosaccharides did not have a significant inhibitory effect on F.graminearum in the plate inhibition test but showed antibacterial effects in both potted and field control experiments,and significantly reduced the field disease index,which was 47.59%and 49.93%lower than CK,respectively.Carbendazim inhibited the growth and yield of wheat.Compared with CK,the plant height,stem diameter,root length,number of roots,fresh weight,and dry weight of wheat decreased by 8.69%,2.90%,21.28%,12.50%,12.83%,and 15.15%,respectively,and the yield of wheat decreased by 13.70%.ZNC promotes the growth of wheat and increases wheat yield.Compared to CK,wheat yield increases by 7.96%,wheat grain protein content increases by 14.45%,and wheat grain vomiting toxin(DON)content decreases by 6.00%.[Conclusion]ZNC may promote wheat growth,increase wheat yield,and improve wheat grain quality while preventing and controlling diseases.Plant immune inducer ZNC provides a new option for preventing and controlling wheat scab.
