Abstract:

Plant diseases, particularly foliar diseases, are one of the major issues limiting India's barley production. Many fungal infections impact barley, resulting in significant crop losses each year. Foliar disease-related yield losses in barley are estimated to vary from 10% to 40% globally. The entitled experiment was conducted in Plant Pathology laboratory, School of Agriculture (SOA), Uttaranchal University Dehradun. The experiment was done in completely randomized design by using poisoned food technique. Three fungicides namely carbendazim, tebuconazole+sulphur, polyram were tested against Bipolaris sorokiniana a fungal pathogen isolated from spot blotch of barley for radial mycelial growth and percent inhibition growth of fungal mycelia at different concentrations (50, 100, 200, 300ppm). The maximum radial mycelial growth was observed in carbendazim 35.66mm at 50ppm and lowest or no mycelial growth was observed by tebuconazole. The maximum percent growth inhibition of mycelia of fungal pathogen was recorded by tebuconazole i.e 100% at 100,200 and 300ppm. The lowest percent inhibition growth was recorded by carbendazim 22% at 50ppm. Among all the fungicides tebuconazole was found to be most effective against B. sorokiniana.
