As the temperature finally begins to warm up in the Pioneer Valley, we are finally beginning to see Forsythia blooming, along with star magnolias and daffodils. For those of you on golf courses in the Northeast, you know that means that annual bluegrass weevils will be on the move soon.

A “normal” spring so far…

I will be assisting Dr. Olga Kostromytska in monitoring seven sites in southern New England this year. Two sites are new to us, but we will also be monitoring several sites that have been cooperators for several years now. So far the spring is starting close to "normal".

Rain, rain, go away!

Most of New England has experienced the same steady, unrelenting rain that so many of the WeevilTrak bloggers have mentioned. We have had over six inches of rain in Amherst in the past week, and some areas have had more than that! The steady rain has certainly kept the turf out of summer dormancy, but it has provided plenty of stress.

The first generation of annual bluegrass weevils appears to be winding down in some parts of southern New England, and just reaching its peak in some of the cooler areas.

A Very Slow Start for ABW in Southern New England

The annual bluegrass weevil (ABW) season is off to a very slow start in southern New England. We are monitoring five sites for the Syngenta WeevilTrak program, and most of those sites had only accumulated 10 degree days or less as of April 22. That makes it the coolest spring we have tracked since we began the program in 2009.

Weevils on their way to New England soon

Many golf course superintendents in coastal New England have three feet of snow on the ground – or more! And there are rumors of yet another storm heading our way next week. But believe it or not, spring IS coming and that means that annual bluegrass weevils will be on the move relatively soon.

ABW activity winding down in New England

This year has been unusually "quiet" for ABW activity in southern New England. At least I received very few phone calls or e-mails asking how to manage populations this year. I believe that is in part because the summer was much cooler than recent summers, and we had timely rainfall, at least in most of the region. So in other words, the turf has not been under as much agronomic stress as it was in 2016.

Summer ’17 ABW report

My observations of the summer of 2017 very closely mirror those of my colleagues. In general, weevil damage in southern New England seems to be lower than we have seen in recent years. Samples received last week from our site in Bloomfield, Connecticut revealed very low counts at all locations except one.
