Abstract: Different dosages of tebuconazole for controlling wheat scab and the effects on wheat yield were studied. The results showed that 3 treatments with various dosages of tebuconazole could control wheat scab to a certain degree, among which the better efficacy with 90.95% was received by applying 12 g Tebuconazole per 667 m², showing low morbidity and disease index. Moreover, the yield of wheat was increased by 42.7% per 667 m².
