Pathogenicity of B. gladioli strains isolated from the sporocarp of S. luteus on Agaricus bisporus cap under controlled conditions. The strains Ir1503 (A) and Ir1504 (B) as well as the pathotype strain of B. gladioli pv. alliicola CFBP 2422^PT (C) induced severe pitting and soft rot on the sporocarp of button mushrooms. However, the pathotype strain of B. gladioli pv. gladioli (CFBP 2427^PT, D) and the type strain of B. cepacia (CFBP 2227^T, E) induced only brown blotch on the mushroom caps, while B. cenocepacia CFBP 8617 (F) had only a slight effect on the cap. hpi, Hours post inoculation.
