Abstract

In Northeast Indian tea plantations infection of Fusaruim solani , resulting dieback of tea plant is increasing which causes considerable crop loss during the recent times. In this investigation, native plant extracts, i.e. Acorus calamus L., Azadirachta indica A. Juss., Clerodendrum viscosum Vent., and Xanthium strumarium L. and microbials i.e. Bacillus subtilis and Trichoderma viride Pers. were utilized to evaluate the efficacy in controlling dieback disease of tea. These extracts inhibited the growth of Fusarium solani by 60-90%. In field application of C. viscosum and X. strumarium extracts reduced the disease up to 89.3% and 81% respectively. More than 70% disease reduction was observed when aqueous extracts of A. calamus and A. indica were used separately. Maximum disease reduction was achieved up to 86.9% due to application of T. viride . The results, thus, suggested the potential use of herbal extracts and microbial strains as an effective component of integrated disease management (IDM) schedule in the organic tea farming. The methods and rate of application are also discussed.

植物提取物和微生物在防治枯萎病中的应用Sacc。

近年来，印度东北部茶园因枯萎病的发生，导致茶树枯死现象日益严重，造成相当大的作物损失。本研究以菖蒲、印楝等天然植物提取物为研究对象。，粘枝胶孔。等微生物，如枯草芽孢杆菌和绿色木霉。利用不同药剂对茶叶枯死病的防治效果进行了评价。这些提取物对茄枯菌生长的抑制作用为60 ~ 90%。田间应用粘草提取物和鹤耳草提取物，防治效果分别为89.3%和81%。菖蒲水提液与籼稻水提液分别使用时，病害降低率达70%以上。施用绿t菌可最大限度地降低病死率达86.9%。因此，草药提取物和微生物菌株有可能作为有机茶园病害综合管理(IDM)计划的有效组成部分。讨论了应用的方法和速度。
