In order to screen effective fungicides for controlling wheat scab, the field tests were carried out using five fungicides such as JS399-19 25%SC, prochloraz+thiophanate-methyl 42%WP, etc. The results showed that JS399-19 25%SC 1 500 mL/hm2, prochloraz+thiophanate-methyl 42%WP 1 200 g/hm2 and carbendazim+triadimefon 25%WP 1 800 g/hm2 could control wheat scab effectively, the control effects were all above 85%. The optimal use time was wheat flowering stage.
