It is well documented and often suggested that the “best” weed management strategy for turf is a healthy, properly managed site. The turf, when growing in an environment that provides water and nutrients when and in the quantity needed, is mowed at the correct height and frequency with a sharp blade, where disease and insects are controlled through the proper species and cultivar selection of judicious use of appropriate pesticides, should have the density and growth potential to out-compete undesired weed species. Unfortunately, many turf stands are not firing on all cylinders and the opportunistic weed species can and will take advantage of shortcomings in the system that open up the turf for weedy invasion. Traffic stress and the mowing heights used on sports fields and golf courses are critical to playability and use but instrumental in increasing weed establishment and persistence. A lawn care client who ignores the suggestions of the LCO and mows too short, too infrequently and waters every day opens the door for weedy species invasion. Choosing the right herbicide and applying it at the correct time and rate offers a viable solution to weed management due to required management for playability and client ignorance or inflexibility.
