Hot and dry in Pennsylvania; ABW in Kentucky

We are entering a period when we typically start to observe 2nd generation larval feeding damage in the Pennslyvania. Turf is incredibly stressed right now, and any marginal control earlier in the month could become apparent now. We've also seen new developments of ABW damage in Kentucky.

Spring ABW generation approaching adulthood in New Jersey

In central and northern New Jersey, the annual bluegrass weevil (ABW) populations are slowly approaching the adult stage. On Tuesday, June 19 at Preakness Hills Country Club (Wayne, northern New Jersey), we found anything from first instar larvae through to young (still reddish) adults but with the majority of developmental stages being fifth instars and pupae. It can be expected that new adults will start to show up in significant numbers on most golf courses in central and northern New Jersey in the last week of June and peak in the first week of July.

Don’t let your guard down against ABW

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. The worst may be over for many of you now, but remember that weevil damage can occur anytime from now through the middle of September.

Be vigilant before ABW summer damage appears

Although there has been some rainfall out west, it is nothing compared to what we saw during the month of May. As mentioned in the previous blog post, severe annual bluegrass weevil (ABW) damage at both northern and southern sites followed almost immediately after the excessive rainfall observed last month.

WeevilTrak Update from the Mid-Atlantic

A lot has happened since my last WeevilTrak post, including the completion of many of our chemical trials, and the appearance of annual bluegrass weevil (ABW) damage in many areas. The weather has, more or less, returned to normal, and growing degree day (GDD) accumulations are more consistent with years past. In fact, the late start to the season was overcome by the end of May, and we now sit ahead of past year GDD accumulations.

Wet, Whacky and Weevilly

The month of May was marked by more than 10 inches of rainfall for most of the Mid-Atlantic region, and the Southern Northeast region. This weather pattern did not and will not stop the annual bluegrass weevil (ABW) for doing their thing.

After the rain, comes the damage

The amount of rain western North Carolina has received the past month is record-breaking. And as we've seen in the past, when the rain starts to let up, annual bluegrass weevil damage appears almost immediately.

Start building an ark

We are rapidly advancing through the first generation in Pennsylvania. Each week seems to bring a new WeevilTrak stage—and a ton of rain. Today is May 23 and we don’t have any rain forecasted in central Pennsylvania, which will break a nine day streak. The warm temperatures that are bringing daily growing degree day Base 50 accumulations in the high teens, plus the ample moisture, have weevils loving life.

If you haven’t already, brace yourself

It is so wet out there. So far in the month of May, we are more than three inches above the average amount of precipitation at multiple sampling sites—and they are calling for more rain next week! A lot of areas are completely saturated, and while that may temporarily slow adult activity, you should expect to see damage in the next week or so if you haven’t experienced it already.
