In a recent article by Kate Ryan for WTOP, Robert Butz, co-owner of Windridge Vineyards in Montgomery County, shares his insights on the escalating issue of the spotted lanternfly, an invasive pest that has become a significant threat to vineyards. Initially, Butz wasn’t too concerned about the pest, as invasive species tend to come and go. However, the spotted lanternfly has proven to be a different challenge, especially for grape farmers.
According to Butz, the spotted lanternfly targets nectar, and unfortunately, the nectar in grapevines is particularly appealing to this pest. The damage caused by these bugs can be so severe that it has the potential to kill entire vines. In response to the growing issue, Windridge Vineyards has reluctantly increased their use of insecticides, but Butz is quick to point out that relying solely on chemicals isn’t a sustainable solution. As he puts it, “Honestly, you can’t spray your way out of the problem.”
Butz and his team have taken a multi-faceted approach to combat the pest. During the winter months, they used plumbers’ torches to burn the egg masses of the spotted lanternflies, while others opt to scrape them off. In addition to this, Butz has implemented strategies such as isolating vines from nearby hedgerows, which can serve as resting spots for the lanternflies.
He has also noted the pest’s preference for walnut trees and the invasive Tree of Heaven (ailanthus), both of which are present on the property. Butz has made the decision to leave the walnut trees alone, as they are a heritage species, but the Tree of Heaven is a different story. As Butz states, “It’s a pretty easy call — just get rid of it.”
