- Abstract
In efforts to control bacterial blight caused by Pseudomonas cannabina pv. alisalensis (Pcal) on cabbage using plant defense activators acibenzolar-S-methyl (ASM) and probenazole (PBZ), a soil drench with ASM and PBZ effectively suppressed Pcal lesion formation and reduced bacterial populations compared with a water drench. Although ASM and PBZ activated stomatal-based defense against Pcal resulting in lower bacterial populations and less-severe symptoms, ASM, but not PBZ, induced stomatal-based defense within 4 h after the soil drench. Thus, ASM and PBZ activate a stomatal-based defense in cabbage against Pcal but differ the timing of induction.
