“…1,2 These diseases are usually caused by fungal pathogens that are commonly controlled by the application of synthetic fungicides. 3 However, natural products, classified as biopesticides by the U.S. Environmental Protection Agency, 4 are emerging as a promising alternative for crop protection. 5 This is due to increasing concerns regarding the environmental impacts of synthetic pesticides, as well as stricter controls on their use and the appearance of fungicide-resistant strains.…”

Synthetic fungicides are a common treatment for post-harvest diseases in fruits, although demand is increasing for alternatives such as biopesticides. The aim of this work was to investigate the presence of naturally occurring antifungal compounds in Brazilian specimens of the weed Conyza canadensis. Two compounds [(4Z)-lachnophyllum lactone and (4Z,8Z)-matricaria lactone] were isolated and their antifungal activities were evaluated against eight postharvest disease fungi. Aspergillus niger, Cladosporium sp., and Penicillium digitatum proved susceptible to the treatment (minimum inhibitory concentrations varying from 32 to 64 µg mL -1 ). These fungi are common postharvest pathogens of fruits and vegetables, causing rots and secreting mycotoxins. A green and sustainable extraction method employing pressurized hot water was developed and optimized (100 °C, 4 × 1 min cycles). Yields of 1.46 and 0.24 mg g -1 were obtained for (4Z)-lachnophyllum lactone and (4Z,8Z)-matricaria lactone, respectively. The extract could be applied directly to fruits and vegetables in postharvest treatments.

“…In addition, the level of protection of antagonistic yeasts against pathogens can be influence by the concentration of yeast inoculum, as previously reported (Hernández-Montiel et al, 2012). In the wounds, yeast growths rapidly, but on intact fruit surfaces the antagonist populations usually diminish to the level of natural epiphytic microflora (Droby et al, 2009;Liu et al, 2013). In these sense, the use of adjuvants like Tween 80 (as surfactant) or dextrose (as nutrient) could be an alternative to a better distribution and maintaining of antagonistic yeast population on carposphere at concentrations suitable for biological control, as previously reported (De Cal et al, 2012;Spadaro and Droby, 2016 (Chalutz and Wilson, 1990;Droby et al, 1999;Taqarort et al, 2008).…”

“…In this way plant diseases impact negatively on human wellbeing through agricultural and economic losses (Anderson et al, 2004). Traditionally, control postharvest decay is mainly based on the use of synthetic fungicides, however the demand from consumers for products free of chemical residues and the appearance of fungi resistant to these compounds has hampered the control of pathogens (Liu et al, 2013). Thus, an alternative to chemical methods could be the biocontrol of pathogenic fungi by antagonistic microorganisms.…”

“…These studies ascribed biocontrol activity to four major modes of action: (1) competition for nutrients and space, (2) antibiotic production, (3) induction of host resistance , and (4) direct parasitism (Bélanger et al, 2012;Janisiewicz and Korsten, 2002). The different modes of action were recently reviewed by Liu et al (2013) and by Spadaro and Droby (2016). Both reviews highlight important additional features of successful antagonists, including biofilm formation, quorum sensing, production of diffusible and volatile antimicrobial compounds, competition for iron, the role of oxidative stress, alleviation of oxidative damage, and the production of ROS by the host and the antagonist.…”

“…how do incidental microorganisms or mixtures of antagonists affect pathogen/antagonist interactions, and how does the nutrient/chemical composition at the wound site affect the antagonist, other microflora, the infection process, and the wound response? As initially described by Droby et al (2009) and expanded on by Liu et al (2013), the performance of a biocontrol agent can be seen as the result of complex mutual interactions between all the biotic (organisms) and abiotic (environmental) components of the system. Although these interactions have been the subject of postharvest biocontrol research for 30 years, our understanding is still very incomplete.…”

A B S T R A C TPostharvest biological control agents as a viable alternative to the use of synthetic chemicals have been the focus of considerable research for the last 30 years by many scientists and several commercial companies worldwide. Several antagonists of postharvest pathogens have been identified and tested in laboratory, semi-commercial, and commercial settings and were developed into commercial products. The discovery and development of these antagonists into a product followed a paradigm in which a single antagonist isolated from one commodity was also expected to be effective on other commodities that vary in their genetic background, physiology, postharvest handling, and susceptibility to pathogens. In most cases, product development was successfully achieved but their full commercial potential was not realized. The low success rate of postharvest biocontrol products has been attributed to several problems, including difficulties in mass production and formulation of the antagonist, the physiological status of the harvested commodity and its susceptibility to specific pathogens. All these factors played a major role in the reduced and inconsistent performance of the biocontrol product when used under commercial conditions. Although many studies have been conducted on the mode of action of postharvest microbial antagonists, our understanding is still very incomplete. In this regard, a systems approach, that takes into account all the components of the biocontrol system, may represent the best approach to investigating the network of interactions that exist. Very little is known about the overall diversity and composition of microbial communities on harvested produce and how these communities vary across produce types, their function, the factors that influence the composition of the microbiota after harvest and during storage, and the distribution of individual taxa. In light of the progress made in recent years in metagenomic technologies, this technology should be used to characterize the composition of microbial communities on fruit and vegetables. Information on the dynamics and diversity of microbiota may be useful to developing a new paradigm in postharvest biocontrol that is based on constructing synthetic microbial communities that provide superior control of pathogens.
