稻巨座壳小麦致病型检测防控研究进展

Review on detection and control of wheat blast caused by Magnaporthe oryzae pathotype Triticum

稻巨座壳小麦致病型是麦瘟病的致病菌,是一种新近出现并对全球小麦生产造成巨大威胁的危险性真菌。本文总结归纳了稻巨座壳小麦致病型分类学、地理分布和寄主范围等多方面信息,并探讨了该病菌检测和防控等方面的研究进展。迄今为止,该病害防控较为困难,化学杀菌剂并不能提供有效的防治效果,加强检疫并实施严格检疫措施是防控该病害发生扩散的最有效手段。

Magnaporthe oryzae pathotype Triticum(MoT)is the causal agent of wheat blast,emerging as a global threat.A summarized account of the disease caused by MoT,including taxonomy,distribution,host range,symptoms,morphological characteristics and other aspects is given in this paper.Future directions for efficient detection and managing this destructive disease are prospected.To date,the wheat blast control is still difficult,and fungicides are unsatisfactory.The strong quarantine regulations and measures are the most effective methods in preventing the pathogen spread and these are also discussed within.
