BURLINGTON, Vt. (AP) - A University of Vermont professor says he's found an organic way to slow the spread of the hemlock wooly adelgid, a pest that threatens the state's hemlock forests.
Entomologist Scott Costa says he's been working with fungi that feed on the hemlock wooly adelgid, an invasive inspect that has made its way into southern Vermont.
Adelgids have devastated hemlock trees from Georgia through southern New England.
Vermont Public Radio says that to make the fungi more effective, Costa developed a product called MicoMax, which helps the insect-killing fungi adhere to hemlocks. The product is made from sweet whey, a byproduct of the cheesemaking process, and then blended with the fungi.
Costa says tests have shown it can help suppress the adelgid's spread.
