Organic management of paddy blast using indigenous technical knowledge based organic inputs

The present investigation was carried out to evaluate the efficiency and efficacy of organic inputs namely vermiwash, compost tea, matkakhad, panchgavya, biosol and fermented buttermilk cow urine mixture against paddy blast caused by Pyricularia oryzae with the objectives to work out their applicability for ecofriendly nutrient and disease management. Among all the organic inputs fermented buttermilk: cow urine mixture (1: 1) was found to inhibit the pathogen at 10 per cent concentration followed by other organic inputs. Seeds were also treated with organic inputs and beejamrit was found to be the most effective for seed treatment as it resulted in 94.66% seed germination and also reduced Pyricularia infection to 4% compared with control where infection was 24%. In field experiment organic inputs gave good results and biosol treated plots resulted in 36.64 per cent disease control.
