Researchers at Ottawa's experimental farm are hoping to use some hungry, hungry caterpillars to help control a vine that is pushing its way across farmers' fields.
Dog-strangling vine is an invasive species that is gaining root across farmer's fields and backyard gardens in Canada. It's surviving Canadian winters easily and can really only be removed with backbreaking efforts.
"In Ottawa, we see it all over the place, getting into old fields and hedgerows," said Dr. Tyler Smith a researcher with Agriculture and Agri-food Canada. "There is no effective way to control it."
