Development of Trichoderma based bio-formulations for the management of chilli wilt

Author(s): FA Mohiddin, FA Bhat, KA Bhat, ZA Bhat, MA Bhat, B Hamid and Imran Bashir
Abstract: Locally available carriers were used to develop Trichoderma based bio-formulations for the management of chilli wilt. The Trichoderma isolate (K2) was isolated locally and were identified as Trichoderma harzianum on the basis of cultural and morphological characteristics. Combinations of different carriers with different proportion were found effective in maintaining colony forming unit (cfu) load of Trichoderma harzianum for the period of 120 days. Effectiveness of bio-formulations against Fusarium solani causing chilli wilt was conducted at two locations which are considered hot spots of Fusarium solani causing diverse losses to chilli crop. The maximum inoculum load of 6.22 x 108 cfu/g was observed in cow dung-charcoal-molasses (3:2:1v/v) which was followed by cow dung-ash-molasses (3:2:1v/v) with an inoculum load of 6.18 x 108 cfu/gram formulation after 30 days of storage. After 120 days (4 months) of observation cfu load of 6.2 x 106 was found in cow dung-charcoal-dalweed-soil (3:2:1:1v/v) followed by cow dung-ash-dalweed-soil (3:2:1:1v/v) with an inoculum load of 5.62 x 106 cfu/g of formulation. In the field evaluation, seed treatment of Trichoderma harzianum (K2) was found effective in managing chilli wilt (37%) followed by seedling dip (29%). Lowest disease control (12%) was found with the seed treatment and seeding dip of carbendazim and captan. Trichoderma harzianum was found best in managing wilt diseases of chilli as compared to carbendazim and captan.
