摘要

[Objectives] The paper aimed to reduce the damage of wheat crown rot caused by Fusarium graminearum on wheat production. [Methods]Pathogens were isolated from wheat crown rot samples collected in fields,and the major pathogenic fungi were determined as F. graminearum through molecular techniques.Different fungicides were administrated at seedling stage and reviving stage to control the disease. [Results] There were significant differences in control effects against crown rot among different fungicides. Tebuconazole · prochloraz mixture and Carbendazim · triadimefon mixture had good control effects,while such single agents as Tebuconazole and Difenoconazole · propicondzole had good control effects as well. [Conclusions] Seed dressing with agents could significantly reduce the incidence rate of crown rot at seedling stage,and stem spraying at reviving stage had better control effect.
