“…After 7 days of incubation at 24°C in the dark, each fungal culture obtained was purified by successive transfers onto fresh PDA plates. Single-spore cultures were prepared from pure colonies growing on PDA using the serial dilution technique (Karaoglanidis et al, 2011). From the 240 apples sampled (8 storage units × 30 apples/storage unit), 73 isolates of P. expansum, 63 of Alternaria sp.…”

“…The surface-sterilized apples were wounded once at the equator with a terilized pipette tip by making an injury ~0.5 cm in diameter. Then, 20 μl of a conidial suspension (prepared from a 7-dayold culture) of each isolate, adjusted to 10 3 spores/ ml, was introduced into each wound as described by Karaoglanidis et al (2011). The inoculation was performed on 4 fruits per isolate, and the controls included fruits treated similarly with sterilized distilled water.…”

Blue mold rot, caused by Penicillium expansum, is one of the most economically important post-harvest diseases of apple worldwide. The goals of this study were threefold: to evaluate the diversity of P. expansum isolates for mycelial growth, spore production and lesion diameter on apples; to estimate the effects of cold-storage facility conditions on P. expansum population structure; and to investigate the efficacy of three essential oils against P. expansum. The results showed that storage facilities applying fungicides and storing diverse fruit species selected for P. expansum isolates with a larger lesion diameter on apples. In addition, application of fungicides and diversification in stored fruit species significantly select for P. expansum isolates with higher levels of mycelial growth and spore production, respectively. Moreover, the diversity of host species of stored fruit accounted for 38% of the variability observed between storage facilities for the measured fitness parameters in P. expansum isolates and had a stronger effect on P. expansum population structure than fungicide treatment. Essential oils from Mentha pulegium and Syzygium aromaticum significantly decreased mycelial growth and spore production of P. expansum isolates in vitro. Mentha pulegium essential oil also significantly decreased the size of lesions associated with the blue mold rot of apples. Reducing the diversity of stored host species and applying M. pulegium essential oil may be useful in counter-selecting for aggressive P. expansum isolates and reducing losses due to blue mold rot during fruit storage.

“…The detection of the benzimidazole resistance was cited as a critical factor in initiating research into developing broad-spectrum activity of fungicides that are less prone to cause fungicide resistance in plant pathogens and alternative control measures, such as biological as well as integrated diseases control measures (Sugar et al, 1998;Sugar, 2002). Both fungicides were found to be effective against blue mold of apples (Errampalli, 2004(Errampalli, , 2006Errampali and Crnko, 2004;Errampalli et al, 2005bSholberg et al, 2005a;Li and Xiao, 2008;Karaoglanidis et al, 2011). In 2004, two new reduced risk postharvest fungicides were registered for the control of postharvest diseases of fruits, including pome fruit in the USA and subsequently in other countries.…”

“…These results are in agreement with those of Jae-Wook et al (2001) who found that the EC 50 values of kresoxim-methyl were 0.04-0.16 and 0.08-0.16 µg /ml against mycelial growth of P. digitatum and P. italicum, respectively. Moreover, Karaoglanidis et al (2011) showed that P. expansum was sensitive to cyprodinil and fludioxonil with mean EC 50 values of 0.55 and 0.08 µg / ml, respectively.

Green and blue molds caused by Penicillium digitatum and P. italicum, respectively, are the major postharvest cause of orange fruit decay, resulting in economic losses in the citrus industry. Four fungicides (i.e. boscalid, kresoxim-methyl, boscalid+kresoxim-methyl and cyprodinil+ fludioxonil) and the antioxidant butylated hydroxyanisole (BHA) were evaluated separately and in mixtures against P. digitatum and P. italicum causing green and blue mold diseases of navel orange fruits, respectively. The in vitro studies showed that higher (8-11) and lower (3-5) pH values reduced the growth of P. digitatum and P. italicum. Also, the results showed that the premixed fungicide formulations were more efficient in inhibiting the mycelial growth of fungi than individual forms. Both fungi tolerated high concentrations of BHA. The potency of fungicides and BHA against fungi growth was interestingly increased at pH 3 and 9. Also, the fungitoxic activities of fungicides were increased by adding BHA to fungicide-amended medium. The in vivo studies illustrated that all the separated fungicide treatments, particularly the mixtures of them, effectively controlled the diseases, while the separate BHA treatments slightly reduced the incidence of diseases. Also, the addition of BHA to the fungicides greatly increased their efficiencies against the incidence of diseases. Moreover, the potency of fungicide and BHA was considerably increased at pH values of 3 and 9.
