Glyphosate is a widely used and persistent herbicide whose potential risks to environmental safety and human health are of significant concerns. Developing efficient and sustainable remediation strategies is therefore crucial. This study isolated and characterized a novel bacterial strain, NPDY10, identified as Paenibacillus polymyxa, which exhibits dual beneficial functions: efficient glyphosate degradation and broad-spectrum antagonism against soil-borne fungal pathogens. Under optimal conditions (pH 7–7.5, 30–35°C), strain NPDY10 completely degraded 400 mg L⁻¹ of glyphosate within four days, utilizing the herbicide as a carbon source. Metabolic profiling via UPLC-MS/MS confirmed glyphosate degradation via the AMPA pathway, involving C–N bond cleavage to form AMPA and glyoxylate. A visible foam layer formed during degradation in paddy water, serving as a visual indicator of active metabolism. In field trials, NPDY10 successfully colonized the maize rhizosphere, reducing the populations of pathogenic fungi such as Fusarium graminearum and Gibberella zeae while enriching beneficial microorganisms. The strain also demonstrated broad-spectrum antifungal activity, inhibiting 17 plant-pathogenic fungi with inhibition rates ranging from 62.00% to 92.00%. Paenibacillus polymyxa NPDY10 represents a promising multi-functional agent for sustainable agriculture, combining glyphosate bioremediation with direct biocontrol to improve soil health.
