Root-knot nematodes are microscopic plant parasites that enter or feed on roots and can interfere with normal water and nutrient uptake. Purpureocillium lilacinum, formerly known as Paecilomyces lilacinus, is a beneficial fungus studied for its biological interaction with these nematodes. The fungus can colonize nematode eggs and produce enzymes that assist penetration and degradation of egg structures. Incorporating microbial approaches into soil management can complement crop rotation, field monitoring, resistant varieties, and suitable cultivation practices. A broader management strategy helps growers protect root environments while maintaining healthy soil conditions and supporting consistent crop development.
