摘要
夏季斑由Magnaporthe poae引起,是新近发现的一种危害严重的草坪根部病害,尤其对草地早熟禾Poa pratensis具有很强的危害性。较系统地介绍了草坪夏季斑的病症特点、发生发展条件以及流行因素。综述了夏季斑的诊断方法以及寄主范围。重点对夏季斑的防治方法,包括施肥、灌溉、修剪等养护管理措施,化学防治和生物防治进行了总结。将多施缓释性肥料、深灌、保持一定的修剪高度等养护措施配合能够有效地阻止夏季斑的发生,减轻发病症状。化学防治方法是目前主要的防治手段。夏季斑的生物防治尚属研究阶段。
Summer patch, also called summer blight patch or summer ring patch, caused by Magnaporthe, is a fungi discovered recently with great destructibility, which affected the turf grass root especially the Kentucky bluegrass (Poa pratensis). The summary introduced the symptoms, the disease development and the epidemiology of summer patch systematically, also summarized the identification of causative agents and the host range and distribution. The integrating strategies for the management of summer patch including fertilization, irrigation, pruning and the chemical and biological technologies were emphasised on this paper. Slow released fertilizer, deep water irrigation and maintaining a higher mowing height are all effective ways or slow down the symptom. The chemical control is the main prevention measure, and biological control of summer patch is still at a research stage.
