The overall goal of this project is to develop and demonstrate suppressive crop rotations, alone or in combination with anaerobic soil disinfestation (ASD) as non-fumigant soilborne disease management strategies for strawberries. Specific objectives are to:1. Examine the effect of allium crops on Fusarium oxysporum f. sp. fragariae (F.o.f.) population in the soil with and without summer ASD in greenhouse pot trials,2. Study the effect of Summit 515 wheat on Macrophomina phaseolina in the soil with and without ASD in greenhouse pot trials,3. Explore the role of soil microbial community changes in M. phaseolina suppression by Summit 515 wheat,4. Test suppressive crop rotations with or without ASD for F.o.f. and M. phaseolina control in multiple strawberry fields across coastal California (CA),5. Conduct economic analysis of suppressive rotation/ASD systems,6. Disseminate research outcomes via workshops, field days, and webinars, and7. Evaluate the project impact on CA strawberry growers' disease management strategies.
