Northern Zone Solutions for Insects and Weeds Annual Bluegrass Weevils
Annual bluegrass weevil is spreading south and west from the northeast US. These programs provide extended control of annual bluegrass weevils plus provides season-long control of white grubs and caterpillars. Phenological indicators provide only a guide in determining if an application is warranted at a given time and do not replace onsite scouting. For best results immediately water in applications targeting larvae with a 0.125” of irrigation.
