Secondary infection control of bacterial tomato disease using calcium hypochlorite

Abstract

Control of secondary infections of tomato bacterial disease using calcium hypochlorite was evaluated. Effective concentrations of calcium hypochlorite differed between bacterial wilt and canker. In particular, even at 0.2%, calcium hypochlorite could not completely suppress bacterial canker. Furthermore, at concentrations of less than 0.2%, the control effect declined sharply. Alternatively, because concentrations of residual chlorine in calcium hypochlorite solutions decrease in light conditions, the control effects may deteriorate markedly depending on management.
