ABW adult activity picking up in Virginia

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.

August Weevil Update for North Carolina

Despite adult count during increases the last week of July (record highs in some places), very little damage has been observed so far in August. In past years, the first week of August can be a busy time for annual bluegrass weevil (ABW) in Cashiers, North Carolina and mid-August for the Beech Mountain, North Carolina area, but this has not been the case so far in 2018.

First summer ABW generation reaching adulthood in central and northern NJ

In central and northern New Jersey, the first summer generation of annual bluegrass weevil (ABW) populations have already started to show up as adults. There has been little ABW activity at either of the golf courses I follow. However, at our turf farm in New Brunswick, a good number of adults have been observed on some plots and the developmental stages extracted from turf plugs were primarily large larvae and pupae.

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.

2018: The Year of Extremes?

Weather extremes have made 2018 a challenging year to groom your golf course the way you want to. I have met with some frustrated superintendents regarding labor, staffing, wet weather, heat stress and other challenging topics. But ironically, one of the least common topics I have had on visits to golf courses this year has been annual bluegrass weevil (ABW) damage.
