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...
We are now experiencing some spotty ABW damage in central Ohio and western Pennsylvania after an incredibly quiet summer stretch.
ABW issues remain quiet on most of our sites – which I think is a testament to diligent scouting and timely (and effective) controls.
It has been relatively quiet on the ABW front since mid-June. The way I see it, the options are to either: (1) do nothing, or (2) make spot treatments...
I would recommend actively scouting for adults over the next two to three weeks. This stage is by far the most apparent stage and can provide valuable...
Stage 2 has been triggered at all of the sites under our watch, except for our Elmhurst Country Club (located in the coldest part of northeastern Pennsylvania).
Weevils remain elusive in western and central Pennsylvania largely in part to the extended cold weather. So, please be patient and keep scouting!
