Mean values are based on triplicate measurements. Phytopathogens: X.c., X. campestris; E.a., E. amylovora; P.s., P. syringae; R.s., R. solanacearum; M.o., M. oryzae; P.i., P. infestans. Methanol was used as a solvent control. Positive control (K+) for X.c., E.a., and P.s. was 10 μM chloramphenicol; for R.s. 10 μM tetracycline, for M.o. 10 μM nystatin, for P.i. 10 μM cycloheximide; MC, represents agar media controls.
