A colder‑than‑usual winter and an early‑March warm spell have shifted ABW timing.
ABW adult densities are fairly low. No significant damage anywhere on my golf courses and research plots.
Just because there were real problems in spring does not necessarily mean that ABW might not rear its head during summer.
If you are planning to apply an adulticide to manage the adults of the ABW spring generation, it is time to start scouting for them.
Based on the indicator plants and the larval stage average, it is now time to apply larvicides against the mid-size larvae that have started to exit the plants.
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.
Based on the weather forecast for NJ, we can expect to see the beginning of forsythia full bloom and some adult ABWs on the short-mown turfgrass areas.
Annual bluegrass weevil (ABW) numbers have been, and continue to be, low. However, localized issues are not uncommon this time of year.
Due to the warm weather, ABW stages are all over the place now.
The first new adults from the ABW spring generation have started to show up in central and northern New Jersey, and, with the current hot weather, numbers...
Applications for mid-size ABW larvae are around the corner.
We should reach the magical number of GDDs for central and northern NJ by late April; however, the phenological indicator plants are well ahead of the GDDs.
This is a good time for a refresher on predicting weevil activities and timing of ABW-cide applications.
Where ABW larval densities are on the higher side, some damage may occur during the hotter and drier days forecasted.
With the forecast for the next week in NJ showing no rain and lots of heat — and with ABW larvae present mostly in the later stages — keep a wary eye...
The first new adults from the annual bluegrass weevil (ABW) spring generation have started to show up in central and northern New Jersey.
In central and northern New Jersey, ABW populations are moving along with larvae now present up to the fifth stage. At high larval densities, damage might...
Soap flushing is equally effective on greens and fairways, is not affected by temperature and time of day, and can extract more than 90% of any adults...
