Abstract
Abstract The curative activity of the food additives dehydroacetic acid, dimethyl dicarbonate, ethylene diamine tetracetic acid, sodium acetate, and sodium benzoate (SB) was tested in in vivo preliminary screenings against green and blue molds on citrus fruit artificially inoculated 24 h before with Penicillium digitatum and Penicillium italicum , respectively. SB was the most effective compound and it was further tested in trials simulating postharvest industrial applications. Dip treatments for 60 s with 3% (w/v) SB heated above 50  ° C resulted in about 90% reduction of green and blue mold incidence on ‘Valencia’ oranges inoculated, treated, and incubated at 20 °C and 90% RH for 7 days. This treatment was also effective on ‘Lanelate’ oranges, ‘Fino’ lemons and ‘Ortanique’ mandarins, but not on ‘Clemenules’ mandarins. Heated solutions combining SB with low doses (25 or 50 μL L − 1 ) of the fungicide imazalil (IMZ) were synergistic and greatly improved the efficacy of stand-alone treatments. On ‘Valencia’ oranges stored for 8 weeks at 5  ° C followed by 7 days of shelf-life at 20 °C, this combination reduced the incidence of green and blue molds almost by 100%. It was found in additional trials to test the preventive activity that 3% SB dips at 50  ° C for 60 s did not reduce green mold on ‘Valencia’ oranges treated, inoculated with P. digitatum 24 h later, and incubated at 20  ° C for 7 days. It can be concluded from this work that heated SB aqueous solutions might be in the future an interesting nonpolluting disease control alternative for the commercialization of citrus in markets with zero tolerance to fungicide residues.

The performance of postharvest treatments with sodium propylparaben (SPP), alone or combined with low doses of the fungicide imazalil (IMZ), against citrus green (GM) and blue (BM) molds was evaluated on several citrus species and cultivars artificially inoculated with Penicillium digitatum and P. italicum, respectively, and incubated at 20 °C or cold-stored at 5 °C. Effectiveness of 100 mM SPP dips at 20 °C for 60 s was higher on oranges than on mandarins, with GM and BM incidence reductions of...

Preventive and curative antifungal activities of postharvest treatments with potassium silicate (PSi) against green (GM) and blue (BM) molds were evaluated on oranges (cvs. ‘Valencia’ or ‘Lanelate’) artificially inoculated in rind wounds with Penicillium digitatum and P. italicum, respectively. The most effective PSi concentration, the effect of fungal inoculum concentration, and the influence of temporal and spatial factors on antifungal activity were assessed in in vivo primary screenings. Aft...

Abstract The aim of this study was to investigate the ability of two salts, sodium carbonate and bicarbonate, to activate defence mechanisms in citrus fruit against postharvest green mould caused by Penicillium digitatum . In particular, once there was confirmed salt antifungal activity in the absence of direct contact with the pathogen, changes in enzyme activity and expression levels of chitinase, β-1,3-glucanase, peroxidase and phenylalanine ammonia lyase (PAL), and phytoalexin (scoparone, sc...

Abstract Green and blue molds, caused by the pathogens Penicillium digitatum and Penicillium italicum , respectively, are the most economically important postharvest diseases of citrus fruit in all production areas with low summer rainfall. Both fungi are strict wound pathogens that affect all citrus species and cultivars and can infect the fruit in the field, the packing house, and during distribution and marketing. Taxonomy and morphology of the pathogens and factors that can influence fruit i...

ABSTRACT The effect of dimethyl dicarbonate (DMDC) (200 mg/L) sterilization was tested. The reduction of microorganisms and the variation of nutritional and physiological quality in fresh-cut carrot treated by DMDC were evaluated. The results showed that the total aerobic plate count and count of total yeasts and molds in the fresh-cut carrot treated by DMDC were significantly reduced (P < 0.05) by 3.01 and 3.43 log cfu/g, respectively, in comparison with control (the fresh-cut carrot washed by ...

Abstract Green mould, caused by Penicillium digitatum , is responsible for major postharvest fruit losses on the South African fresh citrus export market. Some of these losses as well as fungicide resistance development can be attributed to sub-optimal imazalil (IMZ) residue loading on citrus fruit ( −1 ), which is commonly the case in South African packhouses. This will result in loss of control and sporulation inhibition on decayed fruit. IMZ formulation [IMZ sulphate and emulsifiable concentr...

Abstract The effects of dimethyl dicarbonate (DMDC) (200 mg L −1 ) treatment on microorganisms and quality of Chinese cabbage were investigated. The results indicated that in the different tissues treated by DMDC, a significant reduction ( P ca. 4.49 log cfu g −1 ) and stalk ( ca. 4.45 log cfu g −1 ), as well as the count of total yeasts and molds of the leaf ( ca. 3.02 log cfu g −1 ) and stalk ( ca. 3.62 log cfu g −1 ), was obtained in comparison with the control (sterile water dip). However, i...

The curative and protective activity of sodium bicarbonate (SBC) at 1% alone or in combination with fludioxonil (FLU), thiabendazole (TBZ), or FLU and TBZ together, between 50 and 600 mg/L, was evaluated on fruit of different citrus species and cultivars. Fruits were either artificially inoculated with a resistant (TBZ-r) or sensitive (TBZ-s) strain of Penicillium digitatum or not inoculated and incubated at 20 °C and 90% relative humidity (RH) for 7 days (incubated fruit) or stored at 1.5 °C fo...

Abstract To evaluate the feasibility of acidified sodium benzoate (NaB) as alternative washing solutions of fresh produce, the survival of inoculated pathogens, the background molds and yeasts counts, and quality parameters were compared during 4 and 21 °C storage of cherry tomatoes washed with 3000 ppm NaB at pH 2.0, 200 ppm free chlorine at pH 6.5, water adjusted to pH 2.0, and distilled water. The acidified NaB solution was the most effective in reducing the population of Escherichia coli O15...

Abstract Alternaria brown spot (ABS) is one of the main diseases of mandarins and their hybrids. Its control is based on fungicide applications, but their use is facing difficulties related to the development of resistant pathogen strains and adverse effects on animals, humans and the environment. The present study was undertaken to find feasible alternative solutions to control ABS, by testing the effectiveness of phenolic compounds and alternative formulations present on the market. They were ...

Abstract Sodium dehydroacetate (SD) and sodium silicate (Na 2 SiO 3 ) are food preservatives with antifungal activities against many pathogens. In this paper, the antifungal activity of the combination treatment of SD and Na 2 SiO 3 against Geotrichum citri-aurantii , the postharvest pathogen of sour rot in citrus fruit, was tested. SD and Na 2 SiO 3 combination (1:4, w/w) showed a synergistic inhibitory effect compared to single compound on the mycelial growth of G. citri-aurantii , with the mi...

Abstract Background Citrus is one of the most economically important horticultural crops in the world. Citrus are vulnerable to the postharvest decay caused by Penicillium digitatum and P. italicum , which are both wound pathogens. To date, several non-chemical postharvest treatments have been investigated for the control of both pathogens, trying to provide an alternative solution to the synthetic fungicides (imazalil, thiabendazole, pyrimethanil, and fludioxonil), which are mainly employed and...

Abstract For the first time, efficiency of the carnauba wax-nanoclay emulsions in preserving postharvest quality of ‘Valencia’ fruit was evaluated upon simulated storage and marketing. The different coatings containing nanoclay (i.e., 0.0, 0.5 and 1.0 w%) applied on orange and their performance were compared with uncoated fruit and two different commercial waxes. In general, the presence of nanoclay in the carnauba wax formulation greatly enhanced fruit sensory acceptability, nutritional quality...

Abstract Postharvest decay caused by fungal pathogens is one of the most important factors causing economic losses for the worldwide industry of fresh horticultural produce. Despite the positive results of the use of conventional chemical fungicides, alternatives for decay control are needed because of increasing concerns related to their widespread and continued use. Low-toxicity chemical alternatives evaluated for control of postharvest diseases of temperate, subtropical and tropical fruit, an...
