Purpose of the review: To provide a state-of-the-art review of fungicides that are commonly used before harvest in conventional agriculture to prolong the storage of fresh commodities, and of the alternatives to fungicides recently made available for plant protection. Findings: Considering the high percentage of postharvest loss of fruit due to pathogen spoilage and the frequent occurrence of the development of pathogen isolates that are resistant to one or more active ingredients, alternatives to synthetic fungicides are needed. This review compares the current practices in conventional agriculture that are used to control postharvest rot of fruit with the alternatives to synthetic fungicides that are now available. The review summarizes the different fungicides and the corresponding alternatives, such as natural compounds, decontaminating agents that are ‘generally recognized as safe’, and biological control agents that have been applied in small-scale and large-scale tests. For some cultivated crops, including strawberries, table grapes, and stone and pome fruits, we include the time and method of application of preharvest treatments that can be applied to preserve fruit quality during storage. Limitations/implications: Even considering the research efforts in the search for alternatives to fungicides, at present there are few natural compounds that are as effective as fungicides. However, according to integrated pest management, to overcome the drawbacks that can arise with the use of a single strategy, an integration of methods might provide additive or synergistic effects for disease control. Directions for future research: Further insight at the molecular level into the interactions between host plants and chemicals applied will help us to better understand the changes that occur in host plants following treatments, or the effects of the treatments on the pathogens. This new knowledge will optimize the treatment application to provide the greatest effects with the minimum number/ time/ concentration of treatments applied.

Abstract

Purpose of the review: To provide a state-of-the-art review of fungicides that are commonly used before harvest in conventional agriculture to prolong the storage of fresh commodities, and of the alternatives to fungicides recently made available for plant protection. Findings: Considering the high percentage of postharvest loss of fruit due to pathogen spoilage and the frequent occurrence of the development of pathogen isolates that are resistant to one or more active ingredients, alternatives to synthetic fungicides are needed. This review compares the current practices in conventional agriculture that are used to control postharvest rot of fruit with the alternatives to synthetic fungicides that are now available. The review summarizes the different fungicides and the corresponding alternatives, such as natural compounds, decontaminating agents that are ‘generally recognized as safe’, and biological control agents that have been applied in small-scale and large-scale tests. For some cultivated crops, including strawberries, table grapes, and stone and pome fruits, we include the time and method of application of preharvest treatments that can be applied to preserve fruit quality during storage. Limitations/implications: Even considering the research efforts in the search for alternatives to fungicides, at present there are few natural compounds that are as effective as fungicides. However, according to integrated pest management, to overcome the drawbacks that can arise with the use of a single strategy, an integration of methods might provide additive or synergistic effects for disease control. Directions for future research: Further insight at the molecular level into the interactions between host plants and chemicals applied will help us to better understand the changes that occur in host plants following treatments, or the effects of the treatments on the pathogens. This new knowledge will optimize the treatment application to provide the greatest effects with the minimum number/ time/ concentration of treatments applied.
