Summary
This 2025 study evaluates a novel indole-based organic acid derivative as a postharvest fungicide for controlling blue mold disease in stored apples. The work appears to combine in vitro antifungal screening with postharvest efficacy trials and mechanistic investigation of how the compound suppresses Penicillium expansum infection. The research suggests potential for synthetic, plant-derived alternatives to conventional fungicides in apple storage.
UK applicability
UK apple producers and cold-store operators manage postharvest mold diseases routinely; however, regulatory approval and cost-effectiveness of novel compounds like this indole derivative would need to be established within UK/European pesticide frameworks before practical adoption.
Key measures
As suggested by the title: disease incidence or lesion development on inoculated apples; mechanistic endpoints likely including fungal growth inhibition, enzymatic activity, or pathogenic gene expression
Outcomes reported
The study investigated the efficacy of acetic acid-(1H-indole-3-ethyl) ester as a postharvest fungicide against Penicillium expansum (blue mold) in stored apples, and elucidated the underlying mechanism of action.
