The California Department of Food and Agriculture (CDFA) announced today (Dec. 4) that a Stop Use notice and statewide quarantine have been issued for the organic fertilizer product AGRO GOLD WS to all organic operations registered in California.
Residents who use the product in their gardens or landscapes should also be aware the product may contain weed killers, said Chris McDonald, UC Cooperative Extension natural resources advisor.
"Home gardeners should not use the organic biological amendment Agro Gold WS, which is commonly sold as a bundled package with the organic herbicide Weed Slayer," said McDonald. "CDFA has found Agro Gold WS to have been adulterated with the herbicides glyphosate and diquat, which may kill your plants."
He advises home gardeners to read the CDFA press release at https://www.cdfa.ca.gov/egov/press_releases/Press_Release.asp?PRnum=20-173 for more information.
