“…Green mould, caused by the pathogen P. digitatum, is the most economically important postharvest disease of citrus fruits in all production areas (Eckert & Eaks 1989). The pathogen is the most devastating one, causing about 90% of production losses during the postharvest handling of fruits (Macarisin et al 2007;Moss 2008;Zamani et al 2009). …”

Mohammadi P., Tozlu E., Kotan R., Kotan Şenol M. (2017): Potential of some bacteria for biological control of postharvest citrus green mould caused by Penicillium digitatum. Plant Protect. Sci., 53: 134-143.Ten bacteria isolate (4 Bacillus subtilis, 2 Bacillus pumilus, 2 Bacillus cereus, 1 Bacillus megaterium, and 1 agrobacterium radiobacter) were tested in vitro for antagonistic properties against Penicillium digitatum, the causal agent of citrus green mould. The effect of these bacteria was also observed on mycelial growth, spore germination, and spore production of the pathogenic fungus in broth culture. Extracellular enzyme activities of the bacteria were determined. According to the results of in vitro antagonistic tests and enzymes activities, the most promising bacteria were Bacillus subtilis and agrobacterium radiobacter. These bacteria were tested for disease suppression on lemon fruits. In addition, these bacterial isolates also showed remarkable antifungal activity against the pathogen on lemon fruits. The results of this study showed that Bacillus subtilis and agrobacterium radiobacter showed remarkable antifungal activity against the pathogen. Chitinase and glucanase enzyme activity of all the tested bacteria was positive. Protease enzyme activity was positive in all tested bacteria with the exception of agrobacterium radiobacter. In addition, all bacteria inhibited mycelial growth and spore germination (except agrobacterium radiobacter) of the fungus. Bacillus subtilis, Bacillus cereus, and agrobacterium radiobacter inhibited spore production in broth culture. Bacillus subtilis and agrobacterium radiobacter were tested on lemon fruits significantly reduced disease severity. Consequently, these isolates can be used as new biocontrol agents in controlling the post-harvest decay of citrus fruits caused by Penicillium digitatum.

“…Given the strong dependence of the Gulf Region on food imports, food security issues are largely debated in these states [24,25]. Reports related to apple fruit and apple-derived product contamination by patulin have increased in recent years worldwide [26][27][28][29][30][31], but little information exist on the presence of this mycotoxin in fruit and derivate products imported to Qatar.…”

Introduction: Patulin has raised the international attention because of its health risk. In fact, it has mutagenic, neurotoxic, immunotoxic, genotoxic and gastrointestinal effects in animals. In the present work, patulin and patulin-producing Penicillium spp. in apple and apple-based products marketed in Qatar were analysed. Methodology: Sampling was carried out using apple fruits and apple-based products. Fungi were isolated from undamaged apples, apple juice and baby apple food. DNA extraction was carried out with DNeasy Plant Mini Kit (QIAGEN, Valencia, USA). The molecular identification of fungal isolates was carried out using ITS1-ITS4 PCR. PCR products were sequenced and blasted. Patulin was extracted and analyzed by LC/MS/MS, then quantified using Agilent 1290UHPLC coupled to 6460 triple quadruple mass spectrometer. Results: Forty-five samples of undamaged fresh apple fruits, apple juice and apple-based baby food products sold in different markets in Qatar were surveyed for both fungal and patulin contamination using Liquid Chromatography Tandem Mass Spectrometery (LC/MS/MS). Twentyfive Penicillium spp. isolates were selected, including 23 P. expansum and one isolate each of P. brevicompactum and P. commune. All the tested Penicillium spp. isolates produced patulin in vitro (from 40 to 100 μg/g on Malt Yeast Extract agar medium). Patulin was detected in 100% of apple juice samples at levels ranging from 5.27 to 82.21 µg/kg. Only 5 samples contained patulin levels higher than European Union recommended limit (50 µg/kg). The average patulin contamination was 30.67 µg/kg and 10.92 µg/kg in baby apple juice and in baby apple compote, respectively.

“…Unlike pests and weeds (which, generally, appear over one or two periods), pathogenic fungi may occur several times during the growing season. They also cause serious problems during store and transport of ripe fruit (Jennings 1982;Fox 2006;Faby 2008;O'Neill et al 2012), as they change the taste and the appearance of raspberries, and they may also be a source of mycotoxins (Moss 2008;Mitchell et al 2010). In those cases the protective effect is ensured by deposits of plant protection products Responsible editor: Philippe Garrigues (PPPs) present on the plant surface, mainly on leaves and fruit at a moment of possible infection.…”

“…When used at raspberry plantations, it controls Anthonomus rubi (Herbst) and aphidsAmphorophora idaei (Börn) and Amphorophora rubi (Kalt. ), pests commonly threatening raspberry crops (Kovanci et al 2005;Borowiak-Sobkowiak 2006;Moss 2008). Cyperkill Super 250 EC was applied only once in 2013 (PHI: 4 days), and twice in 2014 (PHI: 34 and 19 days), at a dose of 0.15 l per hectare (0.0375 kg of AI per hectare), before the first crop picking.…”

This paper presents surveys on residue levels of fungicides and insecticides applied according to the raspberry protection program. The field trials were conducted in 2013-2014 on a plantation of raspberry of the Laszka variety dessert raspberry very popular in Poland. Laboratory samples were collected starting from a day of the first fruit picking to the end of harvest. The highest mean residue levels were found for boscalid and pyraclostrobin (2.395 mg/kg and 0.732 mg/kg, respectively), in both cases they were at a level of about 24% of their maximum residue levels (MRLs); and for cypermethrin (0.235 mg/kg; i.e. close to 50% of its MRL). The long-term dietary intakes of those substances by Polish adult consumers were also at low levels of 0.52, 0.22, and 0.04% of acceptable daily intake (ADI), respectively. Therefore, the results obtained indicated that even on day zero of picking ripe raspberries, the pesticide residues not only were well below their corresponding MRLs, but also their daily intakes did not even approach 1% of the ADI. In 2013, pesticide residues in ripe fruit evolved according to a pattern different than in a subsequent year; while in 2014 they changed at a constant exponential rate.
