UC AG Expert Talk: The Blight Phase of Botryosphaeria Disease of Pistachio and Walnut and its Management
2023-10-25 15:00 - 17:00 | CA
Join Dr. Themis J. Michailides, Plant Pathologist and Lecturer from Kearney Agricultural Research & Extension Center, via zoom. He studies the ecology, epidemiology and control of fungal diseases of fruit and nut crops and vines, postharvest diseases, aflatoxin and mycotoxins of nut crops and figs.
In the last two decades diseases caused by Botryosphaeria fungi have become a major problem in nut crops (almond, pistachio, and walnut) and other tree crops in California. Significant research has been completed in these serious diseases over a span of 20 years.
This presentation will focus on the blight phase of the disease that results in infection of the fruit and reduction of yields. In addition, historical approaches to manage this disease will be discussed.

One DPR CE unit (other) and one CCA CE unit (IPM) are pending.
Just as a reminder, here are the requirements for receiving the CEUs:
-each individual requesting CEUs must register individually with their own name and email address and log in from their own device
-participate in the entire session
-complete and pass a final test with 70% or higher; if not passed, the test can be retaken
If you are not familiar with Zoom, log in a few minutes early to familiarize yourself with the Zoom interface.
