Efficacy of warm water disinfection to control sesame bacterial leaf spot caused by Pseudomonas syringae pv. sesami

Abstract

We evaluated the efficacy of warm water disinfection at controlling sesame bacterial leaf spot caused by Pseudomonas syringae pv. sesami. Warm water treatment of seeds at 50°C for 5 to 20 min and 55°C for 5 to 15 min was highly effective in the young seedlings and in the field test. Treatment at 55°C reduced germination vigor but not rate. This suggests that treatment at 50°C is preferable for practical use.
