What is the significance of classifying weeds?

Management is the significance of classifying weeds.

Specifically, a weed often can be found defined as anything that is not where the cultivator, gardener or owner wishes it or as a plant whose benefits are unappreciated, uncommon or unknown. In terms of the first definition, it is important to know whether a weed is broadleaf, grass-like or grassy in order to select the most effective form of control or treatment. In terms of the second definition, it will help in identifying the plant's potential use in natural foods (for example, chicory), ornamental landscaping (for example, Queen Anne's Lace), and traditional medicine (jewelweed).
