Luke Milliron, Butte County UC Orchard Systems advisor, who led the UC Cooperative Extension Program efforts organizing the event, said with walnuts being the number one agriculture product in the county, it is important to provide growers with the latest in the industry’s research.

Next to the podium was Tehama County Solid Waste Management Agency Recycling Coordinator II Paul Freund who presented information on the proper recycling of pesticide containers.
