Soft fruits (Strawberries, Raspberries)

The two principal fungal rots observed with most berry (raspberries, blackberries, loganberries, and gooseberries) and related soft fruit crops are caused by Botr. cinerea and Rhiz. stolonifer. The mold is able to grow on strawberries at temperatures as low as 0˚C, so refrigeration retards, but does not prevent spoilage. Second, Rhizopus stolonifer causes a large proportion of marketing losses of all berry fruits, and Mucor piriformis causes a similar condition in strawberries.
