SUMMARY The eradicative and protective activities of the salicyl‐, 3‐chlorosalicyl‐, 5‐chlorosalicyl‐ and 3,5‐dichlorosalicyl‐anilides and ‐para ‐chloroanilides, against cucumber powdery mildew ( Erysiphe cichoracearum DC.) and tomato leaf‐mould ( Cladosporium fulvum Cke.) have been determined by in vivo glasshouse tests on pot plants. No compound was more effective than salicylanilide against either disease at a non‐phytotoxic concentration. In addition, the in vitro fungitoxic activities of these compounds against spores of tomato leaf‐mould have been determined; several were considerably more active than salicylanilide.
