This week on In the Garden with UC Master Gardeners, we bring you a show from 7 years ago which was a wakeup call for tree growers in Southern California!
We are going to be talking about a very small but treacherous bug and fungus which was killing trees here on the UCI campus and all over SO CAL.
KUCI staff host and UCCE Master Gardener Katrina Kirkeby talked with Dr. John Kabashima, the (at the time) Environmental Horticulture Advisor for the University of California Cooperative Extension, South Coast Research and Extension Center. This pest is called the POLYPHANGOUS SHOT HOLE BORER that vectors 2 fungi - Fusarium and Graphium.
Here at UCI, there were over 1,000 infected trees with this bug and fungus and the number of trees needed to be removed was determined at that time. There are still invasive pest infestations occurring, so this show is intended to call to the public's attention how important it is to monitor your landscape for some of the symptoms illustrated in the accompanying link. Identifying Polyphagous and Kuroshiro Shot-Hole Borer in California (ucanr.edu). More vital information can be researched in the ucanr.edu website!
