Possible Bill Bug Damage?
A year ago we saw the center of a well maintained soccer field go into stress and loose 50% of the turf within 2 weeks in July. We assumed that it was the annual bluegrass dying due to heat stress but we were able to determine that it was a Bill Bug larve infestation that was the cause. The grass plants roots were eaten to the point where they could not survive. This month (early May) the field is being treated to control the damaging Bill Bug larve.
