A team of Spanish researchers have discovered that nettle and other plant extracts, including grape pomace, horsetail, and hops, have the ability to inhibit the growth of Pseudomonas syringae pv. phaseolicola (Pph), the bacterial pathogen causing halo-late blight in common beans. The study found that nettle was the most effective in inhibiting bacterial growth, with a concentration of 1.0 mg/ml required to inhibit Pph growth by 50%. The diversity of phytochemicals in nettle has demonstrated antimicrobial activity against both gram-positive and gram-negative bacteria, making it a potential biopesticide for the biopesticide industry. This could be a game-changer in the fight against plant diseases caused by bacterial pathogens, which currently cause significant crop losses.
