Prior to applying any control measure, always read and follow all label directions. White pine weevils have deposited eggs in the terminals of eastern white pine in Perry county but no larvae are present. Weevils can be found feeding on the leaders and the sap flow from their feeding wounds is apparent. In western Pennsylvania, weevils have started to feed but no eggs are present. Two weeks ago we just started observing adult annual bluegrass weevils hiding on golf course greens.
Adults usually start to migrate from their overwintering site when forsythia is in full bloom.
The early spring weather may move insect activity up this year in comparison to 1999. Please keep alert since this weevil pest of turfgrass caused significant damage to annual bluegrass in 1999. The first generation usually causes the most significant damage, but in 1999 we encountered moderate to heavy damage from the second generation. Each year we receive requests on where to access information on milky disease. Likewise pest control suppression strategies and timing also will vary.
