Evaluation of a Biological Agent for Control of Helminthosporium solani

摘要

Silver scurf of potatoes is an economically important disease of potato caused by Helminthosporium solani Durieu and Mont. Serenade ASO^TM, a biological control agent for H. solani , was tested as postharvest treatment for silver scurf control in 2004 and 2005. Serenade ASO reduced both the incidence and the severity of silver scurf under low disease pressure and the severity of silver scurf under high disease pressure. Under low disease pressure, Serenade ASO delayed the onset of silver scurf until 5 months of storage. Serenade ASO has potential as a biological control of silver scurf under low disease pressure.
