BIOCONTROL EFFICACY OF THE ISOLATED Trichoderma harzianum AGAINST DAMPING OFF AND FOOT ROT DISEASES OF COUNTRY BEAN (Pages : 20 - 25)

The biocontrol efficacy of the isolated Trichoderma harzianum was evaluated against damping off and foot rot diseases of Country bean in the net house conditions. Chickpea bran based formulated T. harzianum and its spore suspension alone or in combination was found to reduce damping off by 42.780-83.84% and foot rot by 46.70-86.56% over control; where Provax 200 WP showed a reduction of damping off and root rot by 74.46% and 77.06%, respectively over control. The combined application of formulated T. harzianum and its spore suspension was also found to increase seed germination by 18.93-65.98% over control. Moreover, the same treatment combination also yielded increased shoot length (19.77-68.42%), root length (25.73-57.80%), and vigor index (47.23-175.08%) over Sclerotium rolfsii inoculated plants at 14 days after sowing. Considering the biocontrol ability in net house conditions, the isolated T. harzianum could be used in the field condition to control different soil borne diseases of vegetable crops.Download
