Fungal plant diseases cause major crop losses. Phytopathogenic fungi's ability to evolve resistance fungicides, alongside ongoing prohibition of such agents by the European Commission because their pronounced adverse effects on human health and environment, make control a challenge. Moreover, development less perilous fungicides is complex task. Here we describe process challenges involved in novel fungicide, from in-vitro studies field experiments. In-vitro experiments with trans-2-octenal, bioactive compound secreted endophytic fungus Daldinia cf. concentrica, revealed its fully inhibit kill phytopathogenic microorganisms. A formulated version trans-2-octenal was then used against soil-borne pathogen Fusarium oxysporum f. sp. lycopersici (Forl), causal agent tomato vascular wilt disease, pot different soil types. We found highest fungicidal activity sandy loam soils, whereas heavy impaired activity. Lastly, investigated Forl semi-field achieved complete elimination Forl, provided rotavated after application. trans-2-Octenal has potential vitro, pots field. © 2025 Society Chemical Industry.

The aim of this study was to evaluate the cytotoxicity and genotoxicity potential biocontrol agents for use against phytopathogens potato seed (Solanum tuberosum L.). Plant extracts from Allium sativum L., Syzygium aromaticum L. Merr. & Perry, Salvia officinalis Curcuma longa as well metabolites bacteria Lactiplantibacillus plantarum KB2 LAB 03 yeast Metschnikowia pulcherrima TK1, were investigated. chemical characteristics plant metabolic profiles tested microorganisms evaluated by GC-MS. An insect cell line Spodoptera frugiperda (Sf-9) human cervix adenocarcinoma cells (HeLa) used in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. single-cell electrophoresis assay estimate DNA damage. microbial depended on their pH. induced stronger damage Sf-9 than HeLa cells. garlic (Allium L.) extract showed highest (IC50 41.6 mg/mL). sage (Salvia 49.6 This is first investigate not only these novel disease control, but also safety humans biodiversity within context sustainable agriculture.
