Fungal Diagnostics

Got a tough soilborne disease issue? Start by calling your local Farm Advisor - they can visit your field and help get a sample to the diagnostics lab at UC Davis. This lab, run by the Swett team, is the backbone of tomato fungal soil-borne disease research in California. The field-level recommendations we share through CTRI-funded projects are built on the diagnostics that start there. This service is only possible thanks to support from CTRI grower members. If you are not sure which Farm Advisor to call or don't have their contact information scroll to the bottom of our Grower Resources Page to find a county-by-county list.
