AbstractTo determine the aerial application effect of 1 9 % picoxystrobin·propiconazole microemulsion on wheat scab，5 treatments were set up， namely 1 9 % picoxystrobin·propiconazole microemulsion， 48 % （20 cyanothiazole·tebuconazole suspension， 30 % prothiazole dispersible oil suspension，3O% triazole ether·fluconazole suspension and clearwater control treatment （CK）. Field aerial application experiments were conducted using unmanned aerial vehicles.Observe the safety of the agent and the phenotypic traits of wheat， calculate the control effect and determine its yield.The results showed that19% picoxystrobin·propiconazole microemulsion had good safety for wheat growth.After treatment，the wheat leaves were wax-yelow to light yellow， the ears and stalks were wax-yellow，and the maturity appearance was relatively good.7 days after the second application of the drug，the prevention and control effect was better.The rate of diseased clusters，the control efficacy of diseased clusters，the disease index and the control efficacy of diseased fingers were 0 . 2 0 % ， 9 5 . 4 5 % ， 0.03 and 9 5 . 6 5 % respectively.28 days after the second administration of the drug，the rate of diseased clusters， the control effect of diseased clusters，the disease index and the control efect of disease fingers were 6 . 0 0 % ，

8 0 . 5 2 % ，2.91and 8 2 . 5 0 % respectively，all of which were higher than those in other treatment groups.The yield results indicated that the yield of wheat treated with 19 % picoxystrobin ∇⋅ ε propiconazole microemulsion was ， which was higher than that of other treatments. Compared with CK，the yield increase rate was 1 1 . 3 9 % .The comprehensive results show that under the conditions of plant protection unmanned aerial vehicles， the application of 19 % picoxystrobin ·propiconazole microemulsion to control wheat scab has a good control effect， a long persistence period，and a certain yield-increasing effect.
