Spring Dead Spot In spite of the name, spring dead spot is a fall/winter disease, so applications begin in fall when average soil temperatures at 2” depth fall below 75ºF for five consecutive days when taken at 11:00 am. These applications should be watered-in with 0.125”. The Envu program below has a satisfaction guarantee and if your expectations are not met, please contact your Envu Distributor or Envu Area Sales Manager.

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 targetting larvae with a 0.125” of irrigation.
