Abstract
Cross protection reduces subsequent severity of infection by Pseudomonas solanacearum in three varieties of tomato. However, it does not reduce the number of infections in plants but only the intensity of the disease. From five periods of time interval used between two inoculation (mild strain followed by virulent strain) namely 24, 15, 12, 8, and 5 hours, the longest time interval is best.
Abaca strain of Pseudomonas solanacearum reduce the severity of infection of tomato and pepper strains of Pseudomonas solanacearum better than ginger strain.
