Weeds County Ag needs to know about!
The California Department of Food and Agriculture (CDFA) classifies exotic and/or invasive weeds based on their known or potential significance as a pest and their distribution in California. The highest (“A-Rated”) rating is given to weeds that have not been detected in California or are of such limited distribution, complete eradication is considered possible
Los Angeles County has five known CDFA A-Rated weeds: alligatorweed, dalmatian toadflax, halogeton, rush skeletonweed and spotted knapweed. Suspected sightings of any of these weeds should be reported in ACWM.
