Abstract

Field experiments were conducted in a brown rot infested soil during 1989–91 at Bhowali (1500 m above sea level) in Kumaon hills of Uttar Pradesh to assess the role of different cultural practices on survival of Pseudomonas solanacearum. All the five cultural practices used in this study proved significant in showing direct reduction in yield loss due to brown rot, bacterial wilt incidence and increase in apparently healthy tuber yield over control. Among treatments, cultural practice of using disease free seed coupled with exposure of infested soil to severe winters by four deep ploughings after harvest of potatoes recorded a maximum of 82.5% reduction in wilt incidence, 83.4% reduction in yield loss due to brown rot and 69.9% increase in apparently healthy tuber yield over control at the end of third year of experiment, while rest of the four treatments did not differ significantly from each other.
