Abstract BACKGROUND In the realm of plant diseases, those caused by fungi and oomycetes are particularly challenging to manage, resulting in significant economic losses. There exist diverse active substances natural products developing them into fungicides holds great significance. At initial phase our research, we discovered that Syringa pinnatifolia extract demonstrates broad‐spectrum inhibitory activity against phytopathogenic fungi. RESULTS S. extracts showed vivo vitro , especially Valsa mali Botrytis cinerea . Totals eight compounds were isolated bio‐guided isolation ( SCX‐1 SCX‐8 ). Among these compounds, 3‐methoxy‐4‐hydroxybenzaldehyde SCX‐2 ) pinnatifone A found have excellent antifungal activities fungi, half maximal effective concentration (EC 50 V was 45.34 μg/mL, EC compound B 9.25 μg/mL. Here a formulation soluble concentrate agent is presented for prevention control tomato gray mold. This included 45% S (containing 2.1% A), 16% benzyl alcohol, 24% absolute ethanol, 5% ethylene glycol, 10% pesticide emulsifier No. 602. The preparation exhibited good protective curative efficacies mold at 100 with 65.32% 54.83%. CONCLUSION Our findings provide valuable insights structural modification derived from lay foundation development novel botanical fungicide utilizing as raw material. © 2025 Society Chemical Industry.
