Invention:
University of Arizona researchers have discovered secondary metabolites that were isolated from P. l. sonorensis bacteria with potential use in nematicides. This technology has the potential to control plant parasitic nematodes effectively, while still being safe and following environmental regulations. In particular, this technology involves the use of biologically active secondary metabolites from insect pathogenic Photorhabdus bacteria, which have antibacterial antifungal, insecticidal and nematicidal properties, including properties against the root knot nematode.
Background:
Nematodes are parasitic worms that feed on living material. They can often be detrimental to plant growth and health as they attack and feed on plant roots. Nematodes occur in almost two-thirds of the fields which are organized for commercial crop and vegetable production. They can infest all parts of the plant leading to severe crop damages. The root knot nematode is known to be one of the most damaging parasites worldwide.
Nematicides are a type of chemical pesticide that is used to kill nematodes. Concerns regarding ill-effects of pesticides and associated perceptions of health and environment degradation have impacted the market. The highest potential lies in the bio-nematicides market on account of eco-friendliness and sustainability.
Applications:
- Commercial field agriculture pest management
- Commercial green house agriculture pest management
- Residential insecticide
- Recreational field facilities
Advantages:
- Immobilization of nematodes
- Ability to kill root-knot nematode
- Reduce the ability for nematodes to invade plant roots
- Environmentally conscious
