The View from Northern New England

When the temperature hit 78°F in central New Hampshire on March 9, I thought we were in for a very early, spring weevil emergence. But the recent cooler weather stopped the weevil emergence. So, relax and be patient. The first adult spray at half green, half gold Forsythia will not be for awhile.

Start Scouting, Not Treating

It may have felt like spring, or even summer this week in most locations of the Mid-Atlantic and Northeast regions, however the calendar tells us that spring will not be here until March 20. This week I traveled throughout Virginia, Maryland, New Jersey and Pennsylvania visiting courses and many times felt "too warm for March". The week of March 6 through 13 was marked by warm days and moderate nighttime temperatures. We use growing degree days (GDD) as one of many tools to monitor annual bluegrass weevil (ABW) activity.
