Role of plant host in determining differential responses to Ralstonia solanacearum and Glomus mosseae

A pot study was aimed to investigate the role of tomato in determining differential response to bacterial wilt causal agent Ralstonia solanacearum pathogen and arbuscular mycorrhizal fungi (AMF) Glomus mosseae. Disease severity was measured after 10, 20 and 30 days of plant growth. The pathogen and...
