A bioformulation for control of black scurf disease of potato

A bioformulation of Trichoderma viride developed at Central Potato Research Station, Jalandhar was evaluated for control of black scurf disease of potato in five field trials carried out between 1999–2001 at CPRI regional stations Jalandhar and Gwalior. Applied as preplanting seed treatment to the disease affected tubers, it reduced black scurf disease incidence and index to nearly one half as compared to the untreated tubers indicating that the bioformulation was effective, for control of black scurf and thus hold promise to replace hazardous organomercurials currently in use.
