Formulation of Eco-friendly Management Package Against Seedling Disease Caused by Sclerotium rolfsii of Lentil

Abstract

The experiments were conducted in the fields of Plant Pathology Division, Bangladesh Agricultural Research Institute, Gazipur during 2014-15, 2015-16 and 2016-17 cropping years to observe the effect of formulated Trichoderma harzianum (Soil amendment with Tricho-compost and seed treatment with T. harzianum spore suspension) and organic soil amendment poultry refuse either singly or in combination with seed treatment with fungicide Provax 200 WP against soil-borne pathogens, Sclerotium rolfsii of lentil causing seedling disease. The partially decomposed poultry refuse was incorporated in the 2 weeks before seed sowing of lentil where Tricho-composts were incorporated in the soil 7 days before seed sowing. Seeds were treated with Trichoderma spore suspension and Provax 200 WP at the time of seed sowing. From this study it was revealed that soil amendment with Tricho-compost or integration poultry refuse with seed treatment by Provax 200 WP performed as the best treatments in reducing seedling mortality and increasing plant growth and yield of lentil which was significantly differed from the other treatments including control. Seed treatment with chemical fungicide provax showed better performance against the disease also seed treatments with Trichoderma spores suspension and soil amendment with poultry refuse which effect at per. Both of them reduced seedling mortality and increased plant growth and yield of lentil.
