IPM Breakfast Meeting Cancellation

Good Morning:

Due to the threat of the coronavirus 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,
