Cultivar susceptibility to Pseudomonas tomato, causal agent of bacterial speck of tomato, was tested under greenhouse and field conditions, with infested tomato seeds, infested soils, and spray-inoculated plants. Of 12 cultivars, Rehovot-13 had field resistance to the pathogen, VF 198 was most susceptible, and Hosen-Eilon was moderately resistant. In one greenhouse trial, cv. Marmande also showed high resistance.
