Effect of Cow Urine and Culture Filtrates of Trichoderma isolate S-13 on Fungal Pathogens of Basmati Rice

Abstract

Rice (Oryza sativa L.) is the principle food crop for majority population of the world. Basmati rice is a unique crop of Himalaya comprising good quality characters and aroma. Basmati rice is being infected by numerous diseases. To manage these diseases, fungicides being used for years. This leads to the residual effects of fungicides on grains and soils so there is needs for alternate approaches to the manage disease. Hence use of cow urine and Trichoderma isolate S-13 is considered as the sustainable approach for management of important diseases of basmati rice. In this study we used different concentration of cow urine, Trichoderma isolate S-13, and Propiconazole (control check) against brown spot and bakanae disease of rice. Among these the maximum mycelial inhibition observed in Trichoderma isolate S-13 @15per cent (66.33per cent) followed by cow urine @15per cent (52.59 per cent). In Bakanae disease the maximum inhibition observed in Trichoderma isolate S-13 @ 15per cent (58.89 per cent) followed by cow urine@15per cent (49.26 per cent).
