Nematicidal and Antimicrobial Activities of Secondary Metabolites from Photorhabdus Bacteria with Applications in Agriculture

Case ID:

This invention is novel compounds derived from Photorhabdus bacteria that have antimicrobial and nematicidal properties with an application for agriculture.



Agricultural pests result in severe economic losses around the globe. However, intensive use of chemical pesticides has a cost on the environment. There is currently a trend towards developing less harmful pesticides, chemical controls, and management practices. Among biopesticides, one strategy is to use compounds naturally produced in the environment that are both cost-effective and safer than conventional pesticides. Photorhabdus is one of the bacteria genera that is being evaluated for its potential use as biopesticide.



  • Non-chemical agricultural biopesticides
  • Root / soil based application for the prevention of fungal growth
  • Root / soil based application for the suppression of nematode activities


  • Low cost of production
  • Bioactive compounds
  • Environmentally safe
