For the most part, ABW damage is low, but I've seen significant turf injury from wet wilt, heat stress and drought.
Scouting across much of Pennsylvania and Ohio has consistently turned up little, if any, meaningful ABW adult or larval activity.
With high temperatures and dry conditions expected across much of the region, turf may rapidly transition from moisture surplus to stress, exposing underlying ABW injury.
Our scouting indicates that this week marks a critical window for ABW management across the central Pennsylvania and central Ohio regions.
There’s been a dramatic decoupling between accumulated GDDs, plant phenology, and adult ABW migration. The divergence we’re seeing this year highlights...
Spring appears to be here in central PA, and with it comes the start of the ABW monitoring season.
Adult annual bluegrass weevil activity has been non-existent for some time, but the battle against ABW continues.
I received numerous reports about surging populations of annual bluegrass weevil (ABW) adults at the end of June, but it appears this is a case of mistaken identity.
Annual bluegrass weevil made a notable comeback this spring in many locations, with more reports of damage compared to recent years.
The upcoming two weeks are critical. The management decisions made during this period will significantly influence the size and threat level of successive...
We are seeing very low adult ABW activity at most of our sites. However, things are about to get busy.
Observed early March ABW activity suggests that they will return, and being vigilant with your scouting is essential.
As we approach Labor Day, I would like to remind turfgrass managers in western PA and OH that this is when we often observe small flare-ups with 3rd generation larvae.
We are pleased to share that the damage caused by ABW has remained relatively minor in the region. However, steady rainfall patterns may contribute to...
The first annual bluegrass weevil (ABW) generation has largely concluded on most of our monitoring sites.
A little bit of patience is needed before pulling the trigger on Stage 3, but things could develop quickly. Here are three things I'm looking out for.
2022 was one of — if not the — lightest ABW years that I can remember.
Apart from collecting your own site-specific population data (which may not be practical for all operations), the WeevilTrak blog is the best resource...
