“…Several previous studies reported Aitemaria spp. as a fruit rot pathogen but they did not provide accurate identification at the species level (10,29,32). Our identification matches two recent reports suggesting that isolates of Altemaria spp.…”

“…as causal agents of postharvest rot in apple fruit in Greece, along with the confirmed prevalence of the patulin-producer fungus P. expan.sum and the atoxigenic pathogen B. cinérea, is of significant importance because they may be responsible for high quantitative yield losses. Furthermore, the toxigenic species can contribute to qualitative deterioration of the stored apple fruit considering that high amounts of apple juices and other by-products are consumed by a vulnerable population such as infants and young children (32). The results of the study can be used for making decisions for implementation of control strategies aiming at the reduction of yield losses and increasing food safety by decreasing mycotoxin contamination of apple fruit by-products.…”

Several species of the genus Fusarium can cause apple fruit to rot while stored. Since Fusarium taxonomy is very complex and has constantly been revised and updated over the last years, the aim of this study was to identify Fusarium species from rotten apples, based on combined morphological characteristics and molecular data. We identifi ed 32 Fusarium isolates from rotten apple fruit of cultivars Golden Delicious, Jonagold, Idared, and Pink Lady, stored in Ultra Low Oxygen (ULO) conditions. Fusarium rot was detected in 9.4 % to 33.2 % of naturally infected apples, depending on the cultivar. The symptoms were similar in all four cultivars: a soft circular brown necrosis of different extent, with or without visible sporulation. Fusarium species were identifi ed by the morphology of cultures grown on potato-dextrose agar (PDA) and carnation leaf agar (CLA). Twenty one isolates were identifi ed as Fusarium avenaceum and confi rmed as such with polymerase chain reaction (PCR) using specifi c primer pair FA-ITSF and FA-ITSR. F. pseudograminearum, F. semitectum, F. crookwellense, and F. compactum were identifi ed by morphological characteristics. F. avenaceum can produce several mycotoxins and its dominance in Fusarium rot points to the risk of mycotoxin contamination of apple fruit juices and other products for human consumption. Pathogenicity tests showed typical symptoms of Fusarium rot in most of the inoculated wounded apple fruits. In this respect Fusarium avenaceum, as the dominant cause of Fusarium rot in stored apple fruits is a typical wound parasite.

“…Among the causes (physiological disorders and mechanical damage) of post-harvest losses, pathogen attack is known to cause considerable extent of damage to their host (Tian & Chan, 2003). In the case of stored fruits, Penicillium expansum alone was estimated to cause between 70% and 80% of the decay (Viñas et al, 1993), and the possibility of PAT contamination is a challenging post-harvest problem (Barkai-Golan & Paster, 2011;Tolaini et al, 2010;Tournas & Uppal Memon, 2009).…”

The occurrence of patulin in fresh apples and apple products is a great burden from health, safety and economic perspectives. Attempts to prevent patulin accumulation in fruits might lead to the excessive use of fungicides. Therefore, guaranteeing the safety of apple foods is crucial for the international apple industry. Recently, literature revealed that application of antagonistic yeasts and other BCAs have been able to disrupt the process of fungal infection and patulin production in apples. Although, over the years the effect of interaction between BCAs and fungi on patulin production has been reported, the exact mechanism(s) of their action remain unclear. Here, the review focused on toxicology and occurrence of PAT; research advances made over the past few years on the interaction between antagonistic yeast, fruits and patulin-producing fungi; the prevalence of patulin in apple fruits and products and the implications of synthetic-fungicide applications. In addition, attention was focused on the mechanism(s) and the enhancement of the biocontrol efficacy of antagonistic for patulin control.
