The 2024 spring weather has been erratic. Here's a recap of the first month of ABW monitoring in Blacksburg, Virginia.
As of March 21, 2024 in Blacksburg, VA, we’ve accumulated 37 GDD (since March 1) and forsythia is in full bloom.
As predicted, the warm sunny weather brought some ABW activity.
Weevil adults are poised and ready to move out of the high grass. It’s time to start monitoring.
It’s been a challenging year for us to find ABW larvae at our monitoring sites in Blacksburg, VA, but we’ve been able to track some definite population...
In Blacksburg, VA, ABW numbers went from almost none in late May to more than 10 per square foot on June 1.
A couple days ago, I posted that we are definitely in the large larvae stage of ABW in southwest Virginia. Well, that was confirmed today.
It could be a light year for annual bluegrass weevil and/or a very good control program.
In 3 days, we saw a jump in ABW adult activity at Blacksburg Country Club and the Virginia Tech Golf Course.
The weather appears to be warming, and the true spring burst of ABW adult activity is probably coming very soon.
In Blacksburg, Virginia, forsythia and Bradford pear are in bloom and daffodils are up all over the place.
Spring is coming early, folks. Time to start checking.
The signs are pointing to ABW adult activity happening very early in Virginia. We should be on the lookout.
ABW adult activity peaked in mid-June but has been steady for over a month now in Blacksburg, Virginia. It suggests that scouting for adults is warranted...
Last week we saw a flush of new ABW adults occurring on golf courses in Virginia. We certainly advise sampling for adults and treating as needed with adulticides.
Be on the lookout in Virginia. We’re seeing a mix of adults and larvae of all sizes.
We saw our first tiny ABW larvae this week, only a single one. Our recommendation is to scout for Stage 3 in western ridge and valleys of Virginia.
As predicted in my previous blog last week, we are in Stage 1 of the weevil control program, where adulticide applications should be considered.
