Compatibility of Trichoderma sp. with Phytoextracts of Locally Available Medicinal Plants in Manipur

Evaluation for compatibility of Trichoderma with phytoextracts revealed that all the three species are not compatible with Allium sativum and Curcuma longa. The incompatibility between the three bioagents with the phytoextracts might be due to the presence of fungitoxic compounds. T. harzianum showed better compatibility with phytoextracts as compared to T. hamatum and T. viride. Comparatively, the bioagents shows more compatible at lower dose of 15% than that of 20% because higher doses of ethanol extracts of plants were more toxic to many fungi. The combinationof plant extracts andbioagents showing highly compatible could be used together in formulation of Integrated Disease Management Schedule. Under in vivo trials of phytoextracts integrated with T. harzianum, T. harzianum + A. cepa sprayed plots showed the least disease incidence and gave the maximum grain yield (4.44 t/ha) followed by A.sativum alone (4.40 t/ha).
