Penicillium digitatum caused green mould while P. expansum, P. crustosum and P. soli-tum caused blue mould on nectarines and plums. © Copyright 2020 CAB International. Initial symptoms of infection are similar for both molds. and on the development of chilling injury (CI) symptoms during cold storage were examined. The spores of this mould are produced in dry chains and are exposed to the air hence their ease to become airborne. Symptoms were easier to detect on light coloured cultivars. Citrus Postharvest Green Mold: Recent Advances in Fungal Pathogenicity and Fruit Resistance. Cellulolytic activity of Penicillium digitatum and P. italicum related to fungal growth and to pathogenesis in citrus fruit. Penicillium species are one of the most common causes of spoilage of fruits and vegetables.For example, Penicillium italicum and Penicillium digitatum are frequent causes of rot of citrus fruits, while Penicillium expansum is known to spoil apples and {798, 2539,3090}. Additionally, physiological and proteomic analysis strategies were applied to explore the inhibitory mechanism of the X33 antifungal extract of the S. lavendulae strain X33 on the mycelial growth of P. digitatum.

Identification to species is difficult. P. digitatum pathogenic on pome fruit, and Vilanova et al. Post-harvest decays are a main source of fruit loss following harvesting, with the most common source of Citrus fruit decay being infections caused by P. digitatum and P. italicum. Sometimes the food people consume can be unsafe. Additionally, control of the disease is further complicated by the emergence of drug-resistant strains due to the extensive use of triazole antifungal drugs. Pencillium fungi are versatile and opportunistic. on Apple and Pear." Barkai-Golan R, Karadavid R, 1991. The disease develops most rapidly at temperatures near 24°C and fruit is thus usually refrigerated during storage (Brown and Eckert, 1988). PdMFS1 can play an important role in the intensification of resistance to fungicides normally used in P. digitatum postharvest treatments. Affected areas appear as watery spots with white mycelium produced at the centre. Runny or stuffy nose 3. Pestic. Penicillium digitatum disease symptoms on pome fruit. The infected area enlarges, resulting in a massive sporulation zone of green or blue color, surrounded by a small narrow band of white mycelium. Journal of Phytopathology, 131(1):65-72. - "Pathogenic Penicillium spp. Penicillium culture plates were graciously provided by John I. Pitt , Commonwealth and Industrial Research Organization, Division of Food Processing, North Ryde, New South Wales, Australia.
