The 2024 spring weather has been erratic. Here's a recap of the first month of ABW monitoring in Blacksburg, Virginia.
Our previous records indicate that higher ABW adult densities are expected in mid-April. Will our prediction hold?
As of March 21, 2024 in Blacksburg, VA, we’ve accumulated 37 GDD (since March 1) and forsythia is in full bloom.
Observed early March ABW activity suggests that they will return, and being vigilant with your scouting is essential.
Due to the warm weather in winter, ABW adults in the Greater Cincinnati and Columbus areas have been active earlier this year. Adulticides should be prepared...
