*****************
Survey of Your Understanding of Crop Biostimulant
Crop biostimulants are not biopesticides (suppressing pest and disease); instead, they are "substances or microorganisms that, when applied to seeds, plants, or the rhizophere, stimulates natural processes to enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, or crop quality and yield." Common active ingredients of biostimulants, which are distinct from those in biocontrol agents, comprise growth promoting bacteria and/or fungi, mycorrhizae, seawood extract, humic substances, kelp, or plant hormones.
To better help vegetable growers with the use of crop biostimulant and implement our future research and extension programs, please spend a few minutes filling out the anonymous survey http://cestanislaus.ucanr.edu/Agriculture/Vegetable_Crops/Biostimulant_Survey/ to share your experience, concerns, confusion, and hopes about an efficient use of these biologics. Your response will be used for research and education

UCCE-UC IPM Biologics Educational Webinar Series
Oct 19, 2020
UC Cooperative Extension Farm Advisors Rachael Long and Zheng Wang are collaborating with UC IPM to host a series of four 1-hour educational webinars on the use of biostimulants and plant growth regulators in crop production, with a focus on vegetable and field crops. Both types of biologics are increasingly used in regulating crop growth and development but also bring discussions on their definition, regulation, and efficacy in field situations. The free webinars are designed for the agricultural community including growers, researchers, crop consultants, pest control advisors, and others in the industry. Please check the attached flyer for details. Webinars will be held Nov. 10th, Nov. 18th, Dec. 3rd, and Dec. 9th. To register, follow the link (https://ucanr.edu/sites/ucexpertstalk/) and click on each webinar topic for the registration page. Contact Zheng Wang (zzwwang@ucdavis.edu) with any questions.

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
