Ralstonia solanacearum, the causal agent of bacterial
wilt disease, is one of the most damaging pathogens of
tomato in Indonesia. Farmers have controlled the disease
using several measurements including application of
bactericides, use of resistant varieties, and implementation
of cultural practices, but fail to obtain disease reduction.
Concern on the harmful effects of bactericidal application
has led to the development of alternative control method
using biocontrol agents.
