Fusarium moniliforme, Rhizopus stolonifer, Alternaria sp., and a yeast were the most common fungi isolated from the mamme and profichi crops of caprifigs. A combination of benomyl and potassium sorbate was the most effective treatment in suppressing development of these molds. Addition of DCNA or chlorothalonil or both did not significantly alter the numbers of molds isolated. Benomyl was essential to control Fusarium, while either potassium sorbate or DCNA controlled Rhizopus. Incidence of Cladosporium and Penicillium ranged from 0 to 3 or 4%. Benomyl treatment significantly increased the incidence of Alternaria and DCNA increased yeasts when either fungicide was applied alone but not when combined with each other or with other fungicides.
