In vitro host range assay on cucumber, eggplant, kohlrabi, okra, green bean, and watermelon inoculated with Ir1503 (A) and Ir1504 (B) as well as the pathotype strain of B. gladioli pv. alliicola CFBP 2422PT (C), pathotype strain of B. gladioli pv. gladioli CFBP 2427PT (D), type strain of B. cepacia CFBP 2227T (E), and B. cenocepacia CFBP 8617 (F). All strains induced soft rot and tissue maceration on cucumber, eggplant, green bean pods, kohlrabi, okra, and watermelon fruit except for B. cenocepacia strain CFBP 8617 which had the most restricted host range where none of the inoculated plant species showed severe soft rot and maceration.
