Description

Saeed Ullah Khattak and three co-authors isolate a fungus-made compound that kills weeds by blocking a plant enzyme, in this 2025 paper. The fungus, Penicillium chrysogenum living inside plant tissue, yields a chlorinated molecule whose structure the team pinned down with chromatography, mass spectrometry, and detailed NMR.

Computer docking placed the compound snugly in EPSP synthase, the enzyme that glyphosate-class herbicides target, with a strong binding score; dynamics simulations confirmed the grip held. In dishes, the compound completely stopped seed germination of sowthistle at moderate doses and strongly suppressed the invasive weed Parthenium. Under identical conditions it outperformed the synthetic herbicide 2,4-D, whose efficacy had faded. The authors present the molecule as a bioherbicide scaffold, a natural and potentially safer starting point for weed management, pending field and safety testing.
