ABW activity in Virginia as April begins

The weather certainly warmed up during the latter part of last week and annual bluegrass weevil (ABW) adult activity has remained steady. Golf course managers should definitely be on alert to scout for adult weevil activity on annual bluegrass and creeping bentgrass collars, tee boxes and fairways.

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".

2019 WeevilTrak Season in Pennsylvania

The Penn State Turfgrass Entomology Lab will be monitoring the same WeevilTrak courses this year as we did last year: Westfield Country Club in northeastern Ohio, Fox Chapel Country Club in Pittsburgh (western Pennsylvania ), and the Country Club of Harrisburg in Harrisburg (central Pennsylvania). These courses are a nice representation of the diversity we see in our region in terms of population density, number of years battling annual bluegrass weevil (ABW), and when damage is most prevalent.

Give use better weather in 2019!

Every spring, many superintendents ask me “Steve- what have you heard about the long-term weather forecast this year?” Typically, I chuckle. I have stopped trying to answer this question. I generally advise preparing for the worst weather and then hope the weather is good.

The weather has warmed up a little and annual bluegrass weevil (ABW) adult activity has increased. Golf course managers should be on alert to Scout for adult weevil activity moving from taller grass overwintering sites on to collars, tee boxes and fairways.

Don’t panic, ABW season in North Carolina has not started in most areas…yet.

In fact, 2019 is currently shaping up to be very similar to 2018: initial warm-up in February followed by cooler temperatures and rain (in some areas) in March. Since we have not seen large numbers of adults in soap flushes yet this year, this post will contain predictions for early-season 2019 annual bluegrass weevil (ABW) activity and control recommendations based on what we observed in 2018.

2019 ABW season in New Jersey

Once again, I’ll be keeping track of annual bluegrass weevils (ABWs) at Pine Brook golf course in Manalapan, New Jersey and Preakness Hills country club in Wayne, New Jersey. However, before we look ahead, let’s see how the last few months have been. Overall, it seems to me that is was a fairly boring winter. There were not a whole lot of far below or far above average temperatures. And to the dismay of my daughter, who got a nice new sled for Christmas, it was a fairly snowless winter, too.

Weevil tracking has commenced in Virginia

Weevil tracking has commenced in Virginia. This year, we are monitoring annual bluegrass weevils (ABW) at three Virginia golf courses: Blacksburg Country Club in Blacksburg, Virginia, Ballyhack Golf Club in Roanoke, Virginia, and The Federal Club in Glen Allen, Virginia.

2018 ABW season summary and 2019 outlook

The ongoing short heat wave, which is supposed to last through Thursday, August 30, combined with the fairly dry conditions in the last 10 days might cause some problems in areas where annual bluegrass weevil (ABW) has not been successfully suppressed over the summer. But starting Friday August 31, the weather is forecasted to go back to more normal temperatures with some thunderstorms and showers. With that, for most golf courses, the ABW season should be pretty much over.

WET a Year!

Last month, I wrote in my blog that adult and larvae annual bluegrass weevils (ABW) were tough to find, potentially due to warm, dry weather from late-June through the middle of July. Then it started raining in the Mid-Atlantic on July 20-21. Guess what? It has not stopped and annual bluegrass weevil activity, though minor to moderate, has picked up on bentgrass and Poa annua.
