WSDA has updated its list of products containing undeclared pesticides, and removed one product that was previously on the list.
Inspectors with WSDA’s pesticide and fertilizer compliance programs have found several products commonly used in horticulture and hydroponics, including marijuana production, with undeclared pesticide chemical compounds in their ingredients.
WSDA issued several “stop sale” orders and Notices of Corrections to the manufacturers and the businesses selling the products, and partnered with the Washington Liquor and Cannabis Board to notify licensed marijuana production operations and retailers.
One product, SNS 217C All Natural Spider Mite Control Concentrate, was originally included on the list of stop sale items, but has been removed after further testing revealed the product did not contain pesticide ingredients.
Testing is being done on 39 product samples taken March 9 and 10 from four businesses in Clark and King counties. Results so far indicate 17 of the products contain pesticide ingredients not declared on the label.
WSDA is still awaiting results on one final product. The products identified as including undisclosed pesticides so far are:
1. Safergro Mildew Cure for Powdery Mildew Control
2. Humboldt Roots
3. Olivia’s Cloning Gel
4. Optic Foliar AT-AK
5. Optic Foliar Overgrow
6. Optic Foliar Switch
7. Rock Resinator Heavy Yields
8. Root 66 1-1-1
9. The Hammer
10. Frost Protection Plus
11. NPK Mighty Wash
12. OG Rapid Flower + Hardener
13. Pyyro K 0-3-7
14. Vita Grow Thunder Boom
15. SM 90

The notice and list of products found with undisclosed pesticides is posted on the agency’s Pesticide and Fertilizer Use on Marijuana in Washington web page and will be updated as additional test results become available.
