Relative effectiveness of different inoculation techniques with bacterial wilt pathogen, Pseudomonas solanacearum-biotype 3, on brinjal

The wilt incidence by Pseudomonas solanacearum Smith has always been erratic following artificial inoculations, probably due to difficulty in maintaining viruloence of the pathogen as well as the influence of certain factors such as soil moisture and temperature. Root and stem inoculation with the pathogen did not make and difference on typical final wilt symptoms. This paper reports the results of inoculation techniques for uniform and rapid development of bacterial wilt in brinjal (Solanum melongena ) for selecting promising resistant varieties.
