Unusually cool early‑spring weather in Chicago has slowed heat accumulation, delaying both plant development and ABW activity.
This spring weather has been a rollercoaster, but the coming weekend should bring warm conditions and a likely increase in ABW adult migration.
ABW adults were observed this past week walking on greens in Central and Eastern Virginia.
As we begin another season of monitoring ABW across the region, it is worth taking a moment to reflect on what we observed during the 2025 season.
Despite a few days of very warm temperatures, we saw zero weevils at BCC or VTGC on March 9.
With the addition of Syngenta's latest innovation, Atexzo, WeevilTrak is now WeevilTrak Plus.
ABW activity has been very slow this month after what has been a very dry August and September across most of the state.
ABW adults have been seen moving on putting greens, but adults in September rarely indicate that there will be a big problem with larvae in October.
No fall activity this year speaks to a short ABW season.
ABW adult densities are fairly low. No significant damage anywhere on my golf courses and research plots.
Cooler weather is approaching in the coming weeks, which may be the first glimpse of light at the end of the tunnel.
The 2025 growing season has been difficult. Continue to scout your golf course for ABW.
For the most part, ABW damage is low, but I've seen significant turf injury from wet wilt, heat stress and drought.
Substantial ABW damage was observed across numerous northern suburb golf courses from mid-July to late July.
ABW populations have shown a very likely three generations so far this year, with the most recent peak in adult activity occurring a couple of weeks ago.
Just because there were real problems in spring does not necessarily mean that ABW might not rear its head during summer.
Pressure is low at every golf course I have visited since the middle of June, but keep your eyes to the ground and scout to avoid sneaky ABW damage.
Peak emergence of the next generation of ABW adults is anticipated within the next 1 – 2 weeks.
