Weeds are the number one pest problem in lawns, golf courses and athletic fields. A weed is any undesirable or unwanted plant. For instance bermuda is a turfgrass, but if you have a fescue lawn and bermuda begins to creep in, the bermuda now becomes a weed.
Weeds come from animals, people, wind and tubers. Weeds are unwanted because they are nuisances, cause extra mowing and obstruct water flow in drainage ditches. They also harbor insects and diseases that may attack turf and other plants.
Poison ivy causes skin irritation and stinging nettle (bull nettle) causes a skin rash. Cool season weeds reduce the vigor of most turf by competing for moisture, nutrients & light.
Effective chemical weed control requires proper identification of the weed. Effective control also requires accurate timing of applications, proper rate of application and proper uniformity of application. Follow all label recommendations.

Identify the season - Cool season weeds – germinate in fall & die in heat. Warm season weeds– germinate in spring & die in cold.
This list is for helping you identify the specific weed. No chemical recomendations are given.
