To the Fairway!

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 weeks.
