Abstract

Aspergillus niger (Tieghem) attacked onion plants causing black mold. The tested bioagent Saccharomyces cervisiae at three concentrations 0.25%, 0.5% and 1%) were evaluated as bioagent on the mycelial growth, incidence and disease severity of black mold. The bioagent Saccharomyces cervisiae was more effective on inhibiting  mycelial growth, disease severity and disease incidence at high concentration 1% than 0.25% and 0.5%.
