Weeds are the number one pest problem in sports fields, and golf courses.
Aggressive competitors for sunlight, moisture and nutrients and prolific multipliers even under adverse conditions, weeds present a challenge for even the most experienced turfgrass managers. The color, texture and growth rate of weeds often contrast markedly to that of the turfgrasses they may be associated with in a lawn or sports field. Consequently, weeds detract from the uniformity of a turf and add to its maintenance requirements. The origin of weeds are as varied as those of our turfgrasses. Most are introduced species from Asia and Europe that were inadvertently brought to this country.
