i have read many things about how billbugs are hard to control because once you realize the damage you cannot control it. also, have been told that big eye bug is the predator...but say i just started a customer on an organic program, and they don't have a healthy soil yet. the big eye is not in great enough numbers to control the billbug, and the customer has majority kentucky bluegrass with no endophytes. how can i prevent billbug damage without applying an insectiside? also, i've been told mixing turf type tall fescue into an established bluegrass looks funny because of the clumping. is it possible to overseed tall fescue into bluegrass?
