Abstract
Abstract Preventive and curative activities of postharvest treatments with selected chemical resistance inducers to control postharvest green (GM) and blue (BM) molds on oranges (cvs. ‘Valencia’ or ‘Lanelate’) artificially inoculated with Penicillium digitatum and Penicillium italicum , respectively, were evaluated. In vivo primary screenings to select the most effective chemicals and concentrations were performed with benzothiadiazole (BTH), β-aminobutyric acid (BABA), 2,6-dichloroisonicotinic acid (INA), sodium silicate (SSi), salicylic acid (SA), acetylsalicylic acid (ASA) and harpin. INA at 0.03 mM, SA at 0.25 mM, BABA at 0.3 mM and BTH at 0.9 mM were selected and tested afterwards as dips at 20 °C for 60 or 150 s with oranges artificially inoculated before or after the treatment and incubated for 7 d at 20 °C. Although it was an effective treatment, SSi at 1000 mM was discarded because of potential phytotoxicity to the fruit rind. Preventive or curative postharvest dips at room temperature had no effect or only reduced the development of GM and BM very slightly. Therefore, these treatments cannot be recommended for inclusion in postharvest decay management programs for citrus packinghouses.

The aim of this study was to find an alternative to synthetic fungicides currently used in the control of devastating fungal pathogen Penicillium digitatum Sacc, the causal agent of green mould disease of blood orange. Antifungal activities of salicylic acid (SA) were investigated against P. digitatum. Treatments consisted of five concentrations (0, 1, 2, 4 and 5 mM). The SA application significantly decreased weight loss percentage and increased life storage of fruits. Also, SA positively affec...

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,...

The present studies aimed to develop control of citrus green and blue moulds caused by Penicillium digitatum and P. italicum, respectively, using elicitors as an alternate to synthetic chemicals. The dose-responsive toxicity of two organic elicitors was evaluated through a series of in vitro and in vivo experiments including pre- and postharvest application of different concentrations of salicylic acid (SA) or methyl jasmonate (MeJ) to ‘Lane Late’ sweet orange fruit for resistance induction. In ...

Abstract Penicillium expansum Link. is the causal agent of apple blue mold, and it can cause severe loss of stored fruit. The use of fungicides is still the major means for postharvest control of this disease. In the present study, we investigated the effectiveness of biological control agents (BCAs) and/or induction of resistance for postharvest control of blue mold on apple ( Malus domestica L. cv Golden Delicious). The BCAs and chemical inducers of resistance tested had direct effects against...

Abstract Citrus black spot (CBS) caused by Guignardia citricarpa represents an important threat to citriculture in Brazil. Limited information is available regarding potential biological control agents and new alternative compounds that may provide protection of orange fruits against the disease. In this study, the effects of commercial products based on Bacillus thuringiensis var . kurstaki ( Bt ) bacterium, Bt pure isolates and Harpin protein (Messenger ® ) on the postharvest control of CBS, w...

β-Aminobutyric acid (BABA), an inducer of pathogen resistance in plants, induced disease resistance in reproductive parts of the plant, such as grapefruit peel tissue. Application of BABA to specific wound sites on the fruit peel surface induced resistance to Penicillium digitatum, the main postharvest pathogen of citrus fruit, in a concentration-dependent manner, being most effective at 20mM, and rather less effective at either higher or lower concentrations. The effect of BABA in inducing resi...

In field experiments, cotton (Gossypium hirsutum/G. barbadense) plants were treated with foliar applications of the synthetic activators 2, 6-dichloroisonicotinic acid (INA) or benzo [1, 2, 3] thiadiazole-7-carbothioic acid S-methyl ester (BTH) and the severity of natural infection with Alternaria macrospora, Xanthomonas campestris pv. malvacearum and Verticillium dahliae was assessed. Percentage leaf area infected with A. macrospora was significantly (P=0.05) lower in plants following one appli...

Abstract Although green mold rot caused by Penicillium digitatum is a major postharvest disease in mandarin fruit, the fruit’s defense mechanism at the metabolomic level is largely unknown. Here, the expressed metabolome network leading to plant resistance to stresses induced by exposing of different agents was analyzed. Inoculation of mandarin fruits with eight individual agents, including four Bacillus cyclic lipopeptides (CLPs) produced by B. subtilis ABS-S14, three phytohormones and P. digit...

Abstract Blueberry fruits were immersed in 100 mg/L acibenzolar-S-methyl (ASM) for 10 min and then stored at 4 °C with 40–50% relative humidity (RH) to investigate the changes of anti-oxidative enzyme activity, antioxidants and secondary metabolites in reactive oxygen species metabolism and phenylpropanoid pathway. The results indicated that ASM effectively enhanced the activity of superoxide dismutase, ascorbate peroxidase, catalase and the content of reduced glutathione and ascorbic acid in bl...

Abstract Green mold caused by Penicillium digitatum is critical diseases for grapefruit fruit. In this study, the alone or combined effects of chitosan and salicylic acid on the control of green mold decay in grapefruit fruits were investigated. The results showed that combination of chitosan with SA treatment provided a more effective control of green mold than alone applying chitosan or SA. chitosan plus SA significantly reduced lesion diameter, disease incidence, while the content of endogeno...

Abstract The present study deals with the control of two important postharvest fruit diseases by application of the supernatant obtained from Bacillus subtilis strains ET-1. The bacteria, B. subtilis was grown in a bench-scale bioreactor and a cell free supernatant (CFS) rich in Iturin A was produced. During the entire bacterial culture time, it has been observed that Iturin A production started at the end of the exponential growth phase and a maximum concentration of 422 mg L −1 was observed af...

Nanguo pear fruit were immersed in 100 mg L −1 Acibenzolar- S -methyl (ASM) for 10 min, then air-dried at ambient conditions and stored for 12 d at 20 °C to investigate the effect of ASM on the activity of enzymes involved in energy metabolism. The effect of ASM on lesion development of the pear fruit inoculated with Penicillium expansum was also investigated in...
