May 2024 - Seeking Tadpole Shrimp Collaborators

UCANR is looking for fields where we can sample tadpole shrimp to test for pyrethroid resistance/susceptibility. We will be gathering soil/shrimp and then using these samples to run laboratory bioassays and measure susceptibility if we get enough shrimp.

What is needed are fields with a history of shrimp pressure. We just need to be pointed to fields that we can collect from and then get either map pin(s) to go to (or directions) or a ranch map that is marked with shrimpy locations or that is paired with specific fields to visit. Feel free to reach out to Sarah Marsh (530-203-8585) and contact Ian Grettenberger directly at imgrettenberger@ucdavis.edu or 360-790-0035.

PRESS RELEASE
FOR IMMEDIATE RELEASE

Contact: Colusa County Agricultural Commissioner’s Office


Mysterious and Unsolicited Seed Shipments Arriving in Colusa County
The California Department of Agriculture (CDFA) has become aware of a number of reports regarding “mysterious and unsolicited seed shipments from China.” These shipments have been arriving at homeowner and business locations throughout the country, including here in Colusa County. The package contents typically list the contents as jewelry, toys, or a number code.


The CDFA is currently in communication with the United States Department of Agriculture (USDA) to determine what the actions will be for these seed packages. In the meantime, CDFA is instructing residents not to open any unsolicited seed packets received. In addition, please DO NOT PLANT or dispose of the seeds. Instead, please immediately contact the Colusa County Agricultural Commissioner’s Office if you come into possession of these unsolicited seeds, and we will arrange to pick up the seeds or you may drop them off at our office.
Seeds that are legally sold to residents of California must go through proper channels in order to protect California’s multi-billion dollar agricultural industry. Colusa County is one of California’s significant seed producing locations. Seeds with unknown origin and those that have not been properly inspected, treated, or tested may have a significant impact on our local industry and ag based economy.


If you have received these seeds, please contact our office via the options below to arrange for delivery or pick up. If you have planted any seed
