Pesticide Use Enforcement

The primary goal of California’s county Agricultural Commissioners’ Pesticide Use Enforcement program is to “Promote and Protect” agriculture, human health, and the environment. Agriculture is the number one industry in Glenn County, valued at nearly $744,304,000 (2020 Glenn County Crop and Livestock Report). The Glenn County Department of Agriculture is committed to protecting human health and the environment, dedicating the majority of staff time to this program. Our department partners with the California Department of Pesticide Regulation (CDPR) and the Structural Pest Control Board (SPCB) to enforce state laws and regulations pertaining to pesticide use, sales, permitting, licensing, worker protection, and pesticide use reporting.


Primary activities include:

  • Issuing both Restricted Materials Permits and Operator Identification numbers to property operators and land owners who wish to purchase and use pesticides
  • Evaluating proposed applications to determine if specific pesticides can be safely and effectively used
  • Performing Pre-Application inspections to confirm proper preparation of the site and acknowledging any sensitive areas of concern
  • Performing pesticide use monitoring inspections, focusing on employee safety and environmental protection
  • Performing Headquarter and record inspections to confirm compliance with state and federal laws
  • Reviewing Pesticide Use Reports to monitor the use of Restricted Materials and track the use of commercial and agricultural use of pesticides within Glenn County
  • Investigating complaints of pesticide misuse and taking corrective action when appropriate
  • Providing education and outreach to the community and to our growers

Helpful reminders about continuing education (CE) requirements for those that renew in 2023
(surnames or business names starting with R-Z)
First, determine the amount of CE hours your license or certificate requires. If you are renewing multiple licenses
or certificates, you only need to complete the amount of CE hours for the license or certificate with the most
hours required. If you have excess “Laws and Regulations” CE hours, they can be used towards “Other” CE hours.
Next, ensure you received a certificate of completion for each CE course you attended. CE course sponsors are
required by regulation to give each attendee a record of completion with the hours completed in each CE
category. The record of course completion must include all of the following information:
1. DPR identification code number
2. Course date
3. Course title
4. Course location
5. Name of sponsoring organization
6. License or certificate holder’s name
7. License or certificate holder’s DPR license or certificate number
8. Hours credited in each category
9. Licensee’s original signature
The above information is required to be kept by each licensee and each course sponsor for three years. DPR may
request copies of these records at any time. You should check your CE certificates to confirm they contain the
required information. If you are missing any certificates of completion or have questions about CE hours earned
for a course, please contact the sponsor of the course in question. Course sponsor information can be found on
the DPR web page sorted by date. A delay in completing your CE can result in you not having enough hours to
renew. Avoid having to retest by getting your required hours as soon as possible.
If you are still searching for CE, there are currently many online and correspondence-style courses available that
can be taken during the day, evening, or weekends to satisfy CE requirements. Please check our list of approved CE courses.
DPR encourages you to submit your renewal applications before October to ensure that you are renewed by early
December. This will allow adequate time for you to register with the County Agricultural Commissioner office
prior to the New Year. It also allows extra time for DPR staff to identify any problems and resolve any issues
before your license expires.

Before you spray run a bee check

GROWERS/PCBs: Before you Spray – check for Bees!

Click here to see if bees are being kept within one mile of your application site.  Not all registered beekeepers request notification however, as an applicator, you are required to check for apiaries around the site prior to spraying a pesticide toxic to bees.  This is only applicable to sites with blooming plants.  This includes not only the planted crop but also any weeds in the field and adjacent fields, roadsides, or ditches.  The website BeeWhereCalifornia includes “Bee Check”, a tool used to alert you - the applicator about bees in the vicinity of the application site.  A Bee Check shall occur at least 48 hours before each application date.  This system replaces the Tri-County Bee Notification System. If you have any questions, please call the office at 530-934-6501.
