Studies on biovar specific diagnostics for Ralstonia solanacearum Yabuuchi Smith infecting ginger Zingiber officinale Rosc and evaluation of apoplastic microbes for biocontrol

Abstract

Ginger (Zingiber officinale Rosc.) is one of the most important spice crop cultivated in newlineIndia and outside for the spicy vegetable ginger and dried ginger and India is the largest newlineproducer and contributes approximately 32.75% of the world production. Bacterial wilt newlinecaused by Ralstonia solanacearum is one of the major diseases affecting ginger in all newlinethe ginger growing countries. The pathogen R.solancaerum is very notorious due to wide newlinehost range, aggressiveness and ability to survive in soil for many years. Dissemination newlineof the pathogen is through infected seed and soil. Detection and documentation and newlinediagnosis of the pathogen are of utmost importance in studying the epidemiology and newlinealso to develop adequate control strategies. newline
