Antioch FAQ
Is yellow starthistle illegal to have on my property?
It is a C-rated noxious weed, meaning the state requires local control efforts. Owners are expected to prevent its spread, and unmanaged infestations may trigger abatement orders.

For residential properties yes, following label directions. Commercial applications require a licensed Qualified Applicator; glyphosate and triclopyr are commonly effective but check product labels for California-approved uses.
