A Photographic Diagnostic Guide for Identification of the Principal Cranberry Fruit Rot Pathogens

Abstract

Many fungal species contribute to the cranberry fruit rot disease complex, the most devastating disease problem of cranberry crops, but the most significant economic losses can be attributed to a subset of five to seven species. Identifying these pathogens requires rotten cranberries to be culture on different microbiological media, where colony appearance differs. The objective of this report is to provide a photographic identification guide for each of the eight principal fruit rot pathogens when grown on different microbiological media.Accepted for publication 17 April 2013.
