Abstract

Botrytis porri Buchw. on leek as an important storage fungus in Finland.

Abstract

Botrytis porri was a common and economically significant pathogen of stored leeks. Its spread in storage at 0.5 deg C caused a linear decrease in the number of marketable leeks. It was also capable of spoiling leeks stored at -0.5 deg . Spraying with benomyl or thiophanate-methyl 1 or 2 weeks before harvest significantly reduced damage during storage. Botrytis allii and Fusarium avenaceum also caused spoilage but their occurrence was rare.<new para>ADDITIONAL ABSTRACT:<new para>B. (Sclerotinia) porri, found for the first time in Finland, was common and economically important on stored leeks. An increase in infection caused a linear decrease in the number of marketable leeks stored at 0.5 deg C. S. porri damaged leeks even at -0.5 deg . Spraying with benomyl and thiophanate-methyl 1 or 2 weeks before harvest decreased fungus damage during storage.
