Putting Weevils to Work

As we've said before, over the past several years, the Annual Bluegrass Weevil has become one of the most troublesome pests on the golf course.  Given the high percentage of Annual Bluegrass (Poa) in the greens, we have to remain ever vigilant to guard against damage from weevils on the putting surfaces. 

However, as most of the tees and fairways still have very little Poa, we see this as a potential opportunity to get some biological control by allowing them to kill the small amount of Poa.

Weevils have been munching on the Poa on #17 tee.

Even though Poa is much more susceptible to damage from this insect, Bentgrass can also be damaged by weevils during the stress of the summer, and when weevil populations become high.  So, we will allow them to work on the Poa now, then use control measures to knock back the weevil populations in the Bentgrass beginning in July.
