拟盘多毛孢菌属真菌侵染的寄主种类多、范围广,可引起多种经济作物和观赏植物的多类病害,病征具有多样性。在前期对贵州省油茶叶枯病的研究过程中,分离到一个拟盘多毛孢菌的新致病菌KLXY-7-2。通过病原菌的分离与纯化、形态学鉴定和微管蛋白基因(TUB2)构建系统发育树等多种检测方法,KLXY-7-2菌鉴定结果为木防已拟盘多毛孢菌(Pestalotiopsis cocculi)。病原菌与拟盘多毛孢属EF055226.1、EF055231.1真菌聚为一个独立的进化分支,且置信度为99%。本研究所鉴定的油茶木防已拟盘多毛孢菌(Pestalotiopsis cocculi),在油茶叶枯病的相关研究属于首次报道,可为进一步明确该病原菌的发生规律及预防时期提供科学依据。  相似文献

广西相思树病害的调查与防治   总被引:1,自引:0,他引:1  
对广西6种外来相思(马占相思、直干相思、纹荚相思、厚荚相思、杂交相思和黑木相思)的病害进行调查,发现主要病害有4种,次要病害3种,并提出防治方法。相思炭疽病病原为胶孢炭疽菌(Col-letotrichum gloeosporioides),在马占相思、直干相思、纹荚相思、厚荚相思和杂交相思的叶状柄上只产生病原菌的无性阶段,而在厚荚相思叶状柄上可同时出现无性阶段和有性阶段;相思白粉病病原为白粉菌(Oidi-umsp.),为害马占相思、厚荚相思和杂交相思的叶状柄和嫩枝,其中杂交相思白粉病发生普遍而严重,发病期多在3~5月;黑木相思叶状柄尖枯病病原为异色拟盘多毛孢(Pestalotiopsis versicolor),一年四季均可发病;马占相思心腐病,主要发生在树干基部,造成木材的大量损失,病原尚未得到确定。  相似文献

砂仁是我国著名南药之一。砂仁叶枯病是一种新近描述的导致植株枯萎和大量减产的严重病害。症状有叶枯型、斑枯型、星斑型和叶鞘病斑四种。据病原菌形态、培养性状、致病性和奇主范围,鉴定为围小丛壳菌(Glomerella cingulata(Stonem.)Spauld.et Schrenk),分生孢子阶段为盘长孢状刺盘孢(Colletotrichum gloeosporioides(Penz.)Sacc.)。病菌在马铃薯葡萄糖琼脂(PDA)培养基上生长较好,而燕麦(OMA)和葡萄糖酵母膏(DYEA)培养基上较有利于产孢。连续日光灯和试验室散光处理促进孢子形成,而紫外灯照射则抑制孢子产生。分生孢子可以串生方式产生。在供试的23科39种植物中,有9科15种植物发病。该菌田间存活期长达16个月以上。  相似文献
