Goals / Objectives
The objective of this research project is to develop and implement non-fumigant approaches for management of nematodes and other pathogens in California carrot production.

Project Methods
Collaborative research studies consisting of replicated field trials and grower demonstration plots will be established to determine the impacts of organic amendment-based treatments, such as anaerobic soil disinfestation (ASD) and biosolarization for control of root-knot nematodes. Treatments, including biologically-based disinfestation practices and host resistance. Data on treatment establishment characteristics, soil quality parameters of site locations, and levels of redox potential and crop nutrition will be assessed.
