Analytical studies on the management of bacterial blight (Xanthomonas axonopodis pv. malvacearum) in rainfed Bt cotton: An integrated approach to enhancing crop health and yield using CRD design

Abstract

Bacterial blight, caused by Xanthomonas axonopodis pv. malvacearum, is a significant threat to cotton production, particularly in rain fed conditions where Bt cotton is predominantly cultivated. This study investigates the effectiveness of various management strategies to control bacterial blight in rain fed Bt cotton. Field trials were conducted at Department of Plant Pathology Parbhani and Cotton Research Station Nanded, over 2017-18, evaluating the impact of different treatments, chemical controls, disease. The results indicate that integrated management approaches, combining resistant Bt cotton varieties with targeted chemical applications and optimized agronomic practices, significantly reduce disease severity and enhance cotton yield. These findings provide a framework for developing effective bacterial blight management protocols for rain fed Bt cotton cultivation, contributing to sustainable cotton production in affected regions.
