Additive Effect of Soil Application with Trichoderma Enriched FYM Along with Seed Treatment and Drenching withTrichoderma Formulation for Management of Wet Root Rot caused by Rhizoctonia solani in Chickpea

Efficacy of seed dressing, soil application and drenching with Trichoderma harzianum Th3, T. viride, Carbendazim, Dithane M-45 and Carbendazim+Mancozeb against wet root rot of chickpea caused by Rhizoctonia solani was evaluated under field experiment during rabi seasons of 2012-13 and 2013-14. The treatments were also evaluated for improvement in plant growth parameters and yield of chickpea cv Pratap Chana-1. Soil application with Trichoderma enriched farm yard manure (FYM) and Neem cake in different plots was done one week before sowing and seed dressing was done with antagonists and fungicides individually at the time of sowing. At 50 days after sowing drenching with antagonists and fungicides was done. Soil application, seed dressing and drenching with T.harzianum Th3 was found to be most effective in improving germination, shoot length, root length and thereby increasing vigour index of plants. Seed dressing, soil application and drenching with formulation of T. harzianum Th3, reduced wet root rot disease incidence most effectively than only seed dressing along with drenching. Study showed that soil application with Trichoderma enriched FYM gives an additive effect to seed dressing and drenching in reducing disease incidence.
