Description
A bacteria-free liquid that fights crop fungi is developed in a 2026 study led by Li-ming Dai, using fluid left after growing Pseudomonas aeruginosa strain 8-7. Low output and weak knowledge of stability had limited use of the strain, so the team tuned how the bacteria were grown and then tested the filtered product.
Growth tuning lifted antifungal action sharply in lab checks, and the liquid held back all 19 tropical crop pathogens tried, with the strongest effects against two Phytophthora species. Heat, a wide pH range, light, and most metal ions left its action largely intact, and 18 rhamnolipid compounds were identified inside. Field spraying cut a powdery mildew disease index on rubber trees within seven days, supporting farm use after safety checks on seedlings.
