Abstract

Wheat the versatile cereal crop has attained a premier position in the world for its unique consumable protein i.e., gluten, which is vital for bread making properties of wheat flour, along with the straw which is a major source of nutritious feed for cattles. Wheat spot blotch caused by Bipolaris sorokiniana is an important disease. In recent days, triazole group of fungicides are used for managing the spot blotch disease of wheat but continuous use of triazole compounds may lead to development of resistance by the pathogen. Hence an integrated approaches using effective fungicide, commercially available botanical, bioagent and ITK will reduce risk of resistance development. Results of field experiment revealed that among the nine treatments imposed, treatment involving hexaconazole @ 0.1% −hexaconazole@0.1% has recorded lowest percent disease index (13.40%) and highest grain yield (13.33 q ha–1), 1000 grain weight (40.65 g), biomass (8.33 t ha–1) and highest benefit: cost ratio
