1. Prohibited noxious: These weeds are highly invasive, cause damage to the crops and destroy the whole ecosystem. This must be eradicated by killing off the plant’s reproductive and growing parts.
2. Noxious: These weeds must be controlled by preventing their spread and are too numerous to be eradicated.
An additional, non-regulated category is called “nuisance weeds.” The most common nuisance weed is the Dandelion. Properties infested with this weed, along with tall grasses could still be cited as unsightly by the City of Beaumont if these vegetation is over 6 inches tall.
