It is too late for adulticides in New England. Instead, the focus should be on management of larvae feeding inside of the stem.
Our scouting indicates that this week marks a critical window for ABW management across the central Pennsylvania and central Ohio regions.
A substantial increase in adult ABW activity has been observed in early May alongside phenological markers of early spring development.
With the first spotting of early instar immature ABW, now is the time to revisit the plan of attack for ABW management.
An asynchrony between ABW population development and plant phenology/GDD has been noticed this spring, making optimal adulticide application timings challenging.
This week and next week are the times to apply adulticides and/or prepare for larval monitoring.
GDD readings tell us we’re at or near peak adult activity in our region, but phenological indicators don’t fully support the observation. Scouting is...
Larvae sampling suggests we are a little behind expectations based on GDD's and plant phenology, but with upcoming warmer temperatures, I expect the larvae...
Predicting peak ABW adult densities this year is a real headache, but I expect peak weevil densities to start sometime this week in central and northern New Jersey.
We are a little behind on our GDD in VA compared to recent years, and the weather has made it difficult to figure out ABW activity.
The correlation between seeing an increase in ABW adults and the forsythia 50% green (leaves) and 50% gold (flowers) has long been the target, but this...
With expected warmer temperatures in the coming weeks, we expect adult ABW activity in New England to peak near the end of April.
Slow initial start to the ABW season in North Carolina, but things are humming along now!
Our ABW adult sampling showed a slight increase in adult ABW activity. Could this be the peak?
There’s been a dramatic decoupling between accumulated GDDs, plant phenology, and adult ABW migration. The divergence we’re seeing this year highlights...
Two courses in the northern Chicago suburbs were the first to report ABW presence in Chicago in 2023, setting the stage for ongoing tracking this year.
ABW are seen in pitfall traps installed in roughs between overwintering sites and low-cut turf mixtures of annual bluegrass and creeping bentgrass in Ohio.
The winter of 2024/2025 brought significant snow, wind and ice in the Mid-Atlantic and Northeast regions. What does this mean for ABW?
