Postharvest biocontrol agents in fruits and vegetables: mechanisms, applications, challenges, and future perspectives.
Review in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Postharvest losses of horticultural produce, primarily due to microbial decay, remain a major challenge to global food security, accounting for 35-50% of production annually. To control this, overuse of synthetic fungicides has led to pathogen resistance, environmental contamination, and health concerns, prompting a shift toward sustainable biocontrol agents (BCAs). This review comprehensively examines the potential of microbial antagonists (yeasts, bacteria, and fungi), plant-based agents (essential oils and extracts), and natural compounds (e.g., chitosan, alginate, organic acids, etc.) for managing postharvest diseases in fruits and vegetables. Key mechanisms of action including competition for nutrients and space, production of antifungal metabolites and enzymes, biofilm formation, induction of host resistance, and volatile organic compounds are discussed in detail. Application strategies (pre- and postharvest), synergistic integrations with physical/chemical treatments, advantages over conventional pesticides, and major challenges (e.g., formulation stability, regulatory hurdles, and commercialization) are critically analyzed. Emerging approaches such as omics technologies, microbial consortia, genetic engineering, and nanotechnology offer promising avenues to enhance BCA efficacy and consistency. This review highlights successful examples and future perspectives of BCAs in postharvest diseases control setup and more importantly their co-applications together with other natural disease control methods and technologies. Finally, it underscores BCAs as viable, eco-friendly alternatives that can extend shelf life, preserve quality, and support sustainable postharvest management.
