Peaches harvested in September 1994 in Mula, Murcia, Spain, at a firm-ripe stage of maturity were either nontreated or washed with water at 18 deg C and sorted in a packing line. Sorted fruit were treated with an aqueous dilution of iprodione at 2 g/litre, pH=7 at 18 deg for 5 min. Half of the iprodione treated fruit were forced-air pre-cooled to reach 0 deg at the endosperm in about 12 h. Two Acremonium spp., A. tubakii and A. rutilum, were isolated from subepidermic tissue of decay margins of fruit after ripening at 15 and 20 deg C, respectively, for 10 days. Acremonium spp. were identified on the basis of asexual morphology. A. tubakii decayed 1.7% of the iprodione-treated and pre-cooled fruit ripened at 15 or 20 deg and the fruit treated by iprodione without pre-cooling but ripened at 20 deg . A. rutilum affected 3.2% of the iprodione-treated fruit ripened at 20 deg and, in contrast to A. tubakii, affected only the surface of the fruit.
