Abstract
Benzothiadiazole (BTH), as Bion WG50, and acetylsalicylic acid (ASA) treatments of potato foliage of field‐ and glasshouse‐grown potato plants were compared for control of two foliar diseases, early blight ( Alternaria solani ) and powdery mildew ( Erysiphe cichoracearum ). The effect of these treatments on harvested tubers wound‐inoculated with the dry rot fungus ( Fusarium semitectum ) was also evaluated. BTH (50 mg a.i. L −1 ) gave almost complete control of both foliar pathogens on inoculated glasshouse‐grown plants and reduced the severity of leaf spotting diseases (mainly early blight) in the field. BTH (100 mg a.i. L −1 ) and ASA (400 mg a.i. L −1 ) reduced the severity of dry rot in field‐grown tubers in some post‐harvest wound‐inoculated treatments but not others and a similar reduction occurred with tubers inoculated post‐harvest from BTH‐treated plants grown under glasshouse conditions. BTH treatment increased β‐1,3‐glucanase activity in leaves > stem > tubers > stolons but not in roots. Increased enzyme activity was recorded for up to 45 days post‐treatment.
