Abstract

A field experiment was conducted during kharif 2009-10 and 2010-11 to evaluate the efficacy of bioagents spray combination to control blast disease in finger millet caused by Pyricularia grisea. Among different spray combinations of bio-agents used as foliar spray, three sprays of Pseudomonas fluorescens, was effective for controlling leaf blast severity and finger blast incidence followed by two sprays of P. fluorescens. Besides, significantly lowest neck blast incidence was also revealed in three sprays of P. fluorescens followed by two sprays of P. fluorescens. Significantly higher grain yield was recorded from three sprays of P. fluorescens. Cost benefit ratio was higher in, three sprays of P. fluorescens and Trichoderma harzianum.
