防治小麦枯白穗药剂和措施的筛选

摘要

The withered white wheatear was caused by diseases occurring in the base of rhizome such as take-all disease, root rot disease, sheath blight. Control measures such as treating seeds with different fungicides, different crops rotation and spraying fungicides during tiller period were performed to select an efficient method. The results showed that seed treatment with fungicides was the most efficient way to control withered white wheatear; and Latitude was the most effective fungicide. Crop rotation and spraying fungicides could decrease the disease rate to some extent, but the effect was not obvious, thus could only be applied as supplementary measures.%小麦枯白穗是由全蚀病、根腐病、纹枯病等根茎基部病害引起的,为筛选和寻找较好的防治枯白穗的措施和方法,进行了种子药剂处理、轮作换茬和分蘖拔节期喷药等措施防治试验.结果表明,药剂种子处理是防治枯白穗病最有效的措施,全蚀净是防治襄阳麦区枯白穗病的最有效药剂；轮作换茬和分蘖拔节期喷药能在一定程度上降低枯白穗率,但效果不明显,只能作为辅助措施.
