Abstract
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 up to 60–90 % after 7 days at 20 °C. Irrespective of citrus cultivar and storage condition, SPP generally improved the curative action of 25 μl l−1 IMZ to control Penicillium molds. In additional tests, 100 mM SPP dips at 20 °C for 60 s only prevented GM on ‘Valencia’ oranges inoculated 24 h after treatment when combined with IMZ. It can be concluded that postharvest SPP treatments show promise as an effective alternative to be considered in citrus postharvest disease control programs.

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 Induced disease resistance against plant pathogens is a promising non-fungicidal decay control strategy. In this study, a potential biocontrol yeast, Rhodosporidium paludigenum , was investigated for its induction of disease resistance against Penicillium digitatum in citrus fruit. The results showed that R. paludigenum is the most effective yeast among three selected yeasts in stimulating the resistance of citrus fruit to green mold. When R. paludigenum was applied 48–72 h before inocu...

Abstract The curative antifungal activity of postharvest sodium ethylparaben (SEP) treatments against citrus green mold (GM) and blue mold (BM) was determined on different citrus species and cultivars artificially inoculated with Penicillium digitatum or Penicillium italicum and incubated at 20 °C and 90% RH for 7 d or stored at 5 °C and 90% RH for 8 weeks plus 7 d of shelf-life at 20 °C. The best concentration was selected in in vivo primary screenings with ‘Valencia’ oranges. SEP at 80 mM was ...

Abstract The curative antifungal activity of postharvest sodium methylparaben (SMP) treatments against citrus green (GM) and blue (BM) molds was characterized on different citrus species and cultivars artificially inoculated with Penicillium digitatum or Penicillium italicum and incubated at 20 °C and 90% RH for 7 d or stored at 5 °C and 90% RH for 8 weeks plus 7 d of shelf-life at 20 °C. Effective concentrations were selected in in vivo primary screenings with ‘Valencia’ oranges. SMP at 200 mM ...

Abstract The effectiveness of sodium bicarbonate (SB), sodium carbonate (SC), sodium silicate (SS), potassium bicarbonate (PB), potassium carbonate (PC), potassium sorbate (PS), calcium chloride (CC), and calcium chelate (CCh) against naturally occurring postharvest decay on ‘Comune’ clementine and ‘Valencia late’ orange fruit was investigated. Aqueous salt solutions (2%, w/v, 20 hl ha −1 ) were applied according to three strategies: (i) by spraying before harvest, (ii) by dipping after harvest,...

Abstract The role of some salts applied in combination with wax on the development of postharvest rots was examined on ‘Tarocco’ and ‘Valencia late’ oranges and ‘Comune’ Clementines. Sodium carbonate and bicarbonate, potassium carbonate and bicarbonate, ammonium bicarbonate, and potassium sorbate, at 6% concentration (w/v), in combination with a commercial wax, were evaluated for their activity against naturally occurring postharvest decay. Fruit were stored for one month at 4 °C (‘Tarocco’ and ...

Edible composite coatings based on hydroxypropyl methylcellulose (HPMC), lipid components (beeswax and shellac), and food preservatives with antifungal properties were evaluated in vivo on clementine mandarins cv. Clemenules, hybrid mandarins cv. Ortanique, and oranges cv. Valencia. Their curative and preventive activity against citrus postharvest green (GM) and blue molds (BM), caused by Penicillium digitatum (PD) or Penicillium italicum (PI), respectively, were determined. Fruits were artifici...

Abstract Several commercially important citrus species and cultivars were artificially inoculated with Penicillium digitatum or Penicillium italicum , immersed 24 h later for 5, 15, 30, or 60 s in water (control) or aqueous solutions of 3% (w/v) potassium sorbate (PS) at 20, 53, 58, 62, 65, or 68 °C, rinsed with tap water, and incubated at 20 °C for 7 d. The most effective treatments were PS applications at 62 °C for 30 or 60 s, which reduced both penicillium molds by up to 20, 25, 50, 80, or 95...

The efficacy of eight food additives as possible alternatives to synthetic fungicides for the control of soilborne pathogens, Fusarium oxysporum f. sp. melonis, Macrophomina phaseolina, Rhizoctonia solani, and Sclerotinia sclerotiorum was evaluated in this study. A preliminary selection of food additives was performed through in vitro tests. The ED50, minimum inhibition concentration (MIC), and minimum fungicidal concentration (MFC) values showed that ammonium bicarbonate and potassium sorbate w...

New hydroxypropyl methylcellulose (HPMC)−lipid edible composite films containing low-toxicity chemicals with antifungal properties were developed. Tested chemicals were mainly salts of organic acids, salts of parabens, and mineral salts, classified as food additives or generally recognized as safe (GRAS) compounds. Selected films containing food preservatives were used for in vitro evaluation (disk diameter test) of their antifungal activity against Penicillium digitatum (PD) and Penicillium ita...

Black rot by Alternaria alternata causes the majority of losses in yellow pitahaya (Selenicereus megalanthus) during postharvest period. Leading strategy for decay control is the use of synthetic fungicides, but constraints associated with the use of this kind of products have led to the search for alternative methods to reduce fungal infections. The efficacy of hot water dips at different temperatures and times (40 °C for 1 min; 40 °C for 2 min; 50 °C for 1 min and 50 °C for 2 min) for controll...

Nine oxylipin mimics were designed and synthesized starting from d-mannose. Their antifungal activity against three citrus postharvest pathogens was evaluated by spore germination assay. The results indicated that all the compounds significantly inhibited the growth of Penicillium digitatum, Penicillium italicum and Aspergillus niger. The compound (3Z,6Z,8S,9R,10R)-octadeca-3,6-diene-8,9,10-triol (3) exhibited excellent inhibitory effect on both Penicillium digitatum (IC50 = 34 ppm) and Penicill...

Fresh and minimally processed fruits and vegetables are highly perishable and readily subjected to postharvest physiological changes and microbial contaminations during postharvest transportation, processing, storage, and retail display. Antimicrobial packaging systems have been studied extensively and some have been applied commercially. These may include active packaging, such as inserted antimicrobial sachets inside the packaging, the controlled release of antimicrobial substances embedded wi...
