Tomato bacterial wilt by Ralstonia solanacearum was suppressed by coagulation of bacterial cells without disinfection using a copolymer of methyl methacrylate with N-benzyl-4-vinylpyridinium chloride in a molar ratio of 3:1 (PMMA-co-BVP) as a polymeric coagulant for bacterial cells. When 10 mg/kg of PMMA-co-BVP was added to soil before transplanting of tomato seedlings, and 2 mg/kg was supplemented once a week after transplanting, a 51% reduction of appearance and a 54% reduction of index of symptoms were observed. PMMA-co-BVP did not exhibit bactericidal activity against R. solanacearum, and coagulation of the bacterial cells appeared to reduce the opportunity for infectious contact of roots of tomato with cells of R. solanacearum, and resulted in disease suppression. PMMA-co-BVP was shown to be highly biodegradable, and the half-life was 5.1 d when treated with activated sludge in soil.
