Researchers tested two natural approaches — peppermint essential oil packaged in tiny nanoparticles and a beneficial biocontrol fungus — to combat root-knot nematodes attacking guar (cluster bean) crops. The study evaluated whether these eco-friendly treatments could suppress the soil pests and help the plants stay resilient without synthetic pesticides.
Nano-encapsulation of peppermint essential oil was used to improve its stability and controlled release in soil, enhancing nematicidal efficacy compared to unencapsulated oil
A biocontrol fungus (likely a Trichoderma or Pochonia species) was applied alongside the nano-encapsulated oil to target root-knot nematodes through combined biological and botanical mechanisms
Guar (cluster bean) plants treated with the combined approach showed improved resilience indicators, suggesting reduced nematode-induced stress compared to untreated controls
