Research Project: Non-Fumigant Nematode Control in Carrot

Location: Citrus and Other Subtropical Products Research

Project Number: 6034-22000-046-012-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2022
End Date: Aug 31, 2027

Root-knot nematodes cause significant damage to carrots, resulting in pre-harvest and post-production loss. This objective of this new research project is to develop and implement methyl bromide alternatives to soil fumigation, including non-fumigant approaches for management of nematodes and other pathogens in California carrot production.

These collaborative research studies will utilize a combination of University research locations and grower-cooperator field locations to determine the impacts of organic amendment-based treatments, such as anaerobic soil disinfestation (ASD) and biosolarization, and non-fumigant nematicides for control of root-knot nematodes. Treatments, including disinfestation practices and host resistance, will be evaluated for impact on root-knot nematode survival, non-pathogenic nematode populations, carrot crop yield and quality, and feasibility for conventional and organic carrot production systems.
