Kari Arnold joined UCCE as an area orchard and vineyard systems advisor in Stanislaus County on Nov. 1, 2017.

Prior to joining UCCE, Arnold was a postdoctoral researcher in the Department of Plant Pathology at UC Davis, where she participated in a statewide extension and outreach program involving viruses in grapevines and the certification program, collaborated with county viticulture advisors and industry leaders to facilitate grower workgroups for regional management of grapevine viruses, and provided presentations at grower meetings.

As a graduate student researcher from 2011 to October 2016, Arnold participated in individual grower meetings and surveys, facilitated and collaborated with a grower workgroup for areawide disease management in Napa vineyards, and conducted statistical characterization of spatial and temporal patterns of insect-vectored plant viruses. From 2009 to 2011, Arnold also worked as a staff research associate and nursery technician for Foundation Plant Services at UC Davis, where she provided employee training; worked on team oriented projects; provided tours, conducted virus indexing, and collected and analyzed data.

Arnold completed an M.S. and a Ph.D. in plant pathology from UC Davis and a B.S. in horticulture from the University of Nebraska – Lincoln.

IPM Breakfast Meeting Cancellation 3/18 & 4/1

Due to the threat of the corona virus that causes COVID-19, University of California employees have been ordered to temporarily cancel all face to face educational events, regardless of size.  In addition, President Trump has advised against meeting in groups of more than 10 people and avoiding restaurants.  Therefore Jhalendra, Kari and I will cancel our March 18 and April 1 Tree & Vine IPM breakfast meetings.  We will monitor the situation closely and will make a decision on future meetings as the situation unfolds. 

Best wishes,
