DIAGNOSTICS SUMMARY RESULTS 2020-2021

The ornamental diagnostics clinic initiated in June 2020 thanks to funding provided by the Plant California Alliance (PCA).  In 2021, the PCA and the National Plant Diagnostics Network (NPDN)  enabled the continuation of this service to ornamental growers in California.  Find the diagnostics results of the most prevalent diseases infecting ornamental plants in California, that we shared at the PCA board meeting on Spring 2022.
