1. Introduction
Botrytis cinerea is the main pathogen that develops on table
grapes during storage, because of its remarkable ability to develop
at low temperatures (Droby and Lichter, 2004). Strict means are
required to control decay with commercial practice relying mainly
on SO2 technology while the seek for alternatives is an ongoing
effort (Lichter et al., 2006; Romanazzi et al., 2012). Commercial
storage of grapes with SO2, during transport or for domestic markets, is routinely very successful but there have been occasional
reports ofcases in which the berries looked intact but suffered from
severe internal decay. These symptoms differed from the typical
symptoms of ‘slip–skin’ or external gray mold but also from ‘melting decay’ that was characterized in California as decomposition of
the skin and oozing which was caused by other microorganisms
