Non-hazardous chemical control of black-scurf of potato

Somani, A.K. (Central Potato Research Station, Jalandhar (India))

In a 2-year field trial, dipping of the tubers of 'Kufri Chandramukhi' potato (Solanum tuberosum Linn.) infected with black-scurf (Rhizoctonia solani Kuhn) in acetic acid 1.0%+zinc sulphate 0.05% for 15 min was as effective as dipping them in organomercurial compound (Emisan-6) 0.5% for 10 to 30 min in controlling the disease. The chemicals were effective on tubers treated before or after cold storage. Seedling emergence and yield remained unaffected by the treatments
