ABW issues remain quiet on most of our sites – which I think is a testament to diligent scouting and timely (and effective) controls.
We continue to recover immatures from our soil core samples, indicating that some adults are expected to emerge throughout the next two weeks.
Currently, I am finding very low levels of adults, callow adults and all different stages of larvae in untreated turf in my trial areas.
With the warm weather we have had in the region, ABW stages and generations have continued to advance quickly.
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...
With the low number of larvae found it may be a time to be patient and keep scouting diligently.
Immatures have been detected from our soil plug samples since the past two weeks. This is an indication that immatures are already present in our system...
ABW adult activity in NC in 2022 was certainly more unpredictable when you compare application timing at each site to that of previous years.
The spring generation of ABW in central and northern NJ is now mostly in the latter stages.
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...
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.
For most of you, the first round of ABW damage should be past the peak. It is important to continue to scout your golf course for larvae if you have made application(s).
Be on the lookout in Virginia. We’re seeing a mix of adults and larvae of all sizes.
So far, the 2022 ABW season has been very close to a “usual” season in New England, despite the periods of somewhat cooler temperatures, with no significant...
Our data indicates that affected golf courses might start seeing the new flush of adults as soon as sometime during next week, or during the first week of June.
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.
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).
Everything is lining up that the middle of May will be a critical time for golf courses targeting annual bluegrass weevil (ABW) larvae in fine turf areas...
