小麦赤霉病的生物防治研究进展

小麦赤霉病是我国乃至世界小麦生产中的一种重要病害，可引起小麦产量的损失和品质的下降。化学防治是目前小麦赤霉病防治的有效途径，但由于化学防治的种种弊端，生物防治将是发展的方向。本文主要对小麦赤霉病生物防治菌株的种类、分离鉴定、防治现状及可能的防病机制进行了综述，并分析了小麦赤霉病生物防治的应用前景。

Progress of the Biological Control on Fusanum graminearum Schw. of Wheat

Wheat head blight (Fusarium graminearum Schw. ) was one of the most important diseases of wheat in the world, which caused yield loss and quality descent. At present, fungicide was an effective way to control wheat head blight, but there were some shortages of chemical control. Biological control would be the direction to prevent from wheat head blight. Kinds of biocontrol strains, isolation and identification, progress in biological control and its mechanism on wheat head blight were discussed in this paper. At the same time, the application prospect of biological control on wheat head blight was analysed.
