As the Covid-19 pandemic persists, and as government mandates and University recommendations maintain that we should social distance, I have come to the conclusion NOT to hold the annual SJC and Delta Field Crops Meeting in January. Instead, I am working with colleagues to deliver virtual continuing education early in the new year:
The California Plant and Soil Conference will be held virtually February 1-3, 2021, and registration is now open. Please see the website for more information and to register. We have applied for DPR pesticide licensing credits (2.75), CCA credits (12.75), and Nitrogen Management credits (5) to help growers fulfill their Irrigated Lands Regulatory Program requirement. These credits have not yet been approved and are subject to change.
The UCCE Rice Grower Meeting will also be held virtually on February 11, 2021. This meeting is still being developed, and I will post more information once registration is open. In the meantime, please save the date!
Please don't hesitate to reach out to me if you have questions regarding these events. I hope that the pandemic has not severely impacted you or those close to you, and I wish you safe, healthy, and happy holidays.
