Weed mapping is important and needs to be categorized with treatment. The important information obtained when mapping weeds includes: types of weeds, direction of spread, rate of spread, soil composition, and water table depth.

Herbicides are an effective tool in an integrated weed management plan when dealing with noxious weed infestations. When using herbicides as a treatment, there are some safety factors that should be considered before spraying such as proper use, safety, timing of application, mixing and handling, and storage and disposal of herbicides.

Early Detection and Rapid Response (EDRR) is a strategy utilized in weed control that emphasizes detecting and controlling new, invasive weeds while the populations are localized and small enough to be eradicated. Costs for EDRR are typically far less than the cost of containing and managing vast populations of weeds.
