In the Cleveland, Ohio area, adult annual
bluegrass weevils, (ABW) are on the move and have already entered the
fairways. ABW adults overwinter along
tree lines in leaf litter and high cut turf, adjacent to fairways where they
feed primarily on annual bluegrass.
Monitoring is crucial, as adult migration to
playing surfaces occurs in waves, rather than in a single flush, as a result of
our ever fluctuating early spring temperatures.
What does this mean? Well, this
means that eventually there will be adults and larvae present on your course,
which can be a nightmare when it comes to management strategies.
By monitoring your grass clippings or pitfall
traps for adults, and using forsythia (approximately half bloom) as your phenological
indicator, you can determine when get your initial contact insecticide
down. Luckily, here in Ohio, we have yet
to see any resistance to bifenthrin. Syngenta’s WeevilTrak
also offers research-based control strategies regarding progression of ABW, as
well as correct timing of pesticide applications.
Cleveland superintendents be watchful, ABW
larvae will be chomping on your annual bluegrass in just a matter of a couple
