Effect of different organic matter sources and Trichoderma viride Pers.: Fr. on damping-off of tomato (Lycopercicum esculentum L.) var. CO-1 seedlings caused by Pythium indicum Bal.

摘要

A pot experiment was conducted to evaluate the efficacy of different sources of organic matter (dried leaf materials of Azadirachta indica, Madhuca indica [Madhuca longifolia], Morinda tinctoria, Peltophorum pterocarpum and Thespesia populnea), either alone or in combination with Trichoderma viride, against Pythium indicum infecting tomato cv. Co-1. The application of Trichoderma viride and Thespesia leaf recorded the maximum seed germination (100%), low disease incidence (5.0%), increased seedling growth (15.6 cm/pl), seedling vigour index (1560), and seedling biomass (23.8 mg/pl) in Pythium indicum inoculated unsterilized soil..
