Abstract:

Ralstonia solanacearum isolates collected from wilt affected tomato plants in Coimbatore district of Tamil Nadu were characterized by morphological, biochemical and race analysis. The isolates produced typical irregular, whitish fluidal single colonies along with pinkish center on 1 % TZC amended CPG agar media. Pathogenicity test revealed the representative isolates could wilt the tomato seedlings, and tobacco leaf infiltration assay confirmed its race 1 nature. Biochemical assays revealed the isolates belong to biovar 3 and species level identity was confirmed as R. solanacearum through Biolog finger printing assay.
