Hopeful news in the Vole wars?

" The experiments were conducted using the chemical repellent anthraquinone on citrus trees. Trunk application of anthraquinone resulted in more than a 90 percent reduction in girdling damage. “When we tested it, it was highly repellent and not only that, but it lasted for the entire duration of the project, which was up to about six weeks,” said Baldwin."

n under a minute. Planting season is here for Northern, Mid-West, and Great Lakes NNGA growers, and for those with a vole problem, this pest at times can be devastating to young trees. The product is a bird repellent and unregistered for this application which is why the extension specialist is looking for farmers to complete a survey. I will try and contact Roger A. Baldwin, Ph.D. Wildlife Specialist Department of Wildlife, Fish, and Conservation Biology, the state pest extension specialist for the possibility of out of state farmers to participate in his survey. I will keep the NNGA informed on his answer. Please is the comment section below I completed the interview today Wednesday, April 18, 2018.

Rodney Hart I did a phone interview with
Roger A. Baldwin, Ph.D. a Wildlife Specialist, Department of Wildlife, Fish, and Conservation Biology
One Shields Ave., University of California, Davis, Davis, CA 95616. He welcomes any out of state growers and NNGA growers to participate in his survey of interest for this new vole suppression material. The only request he had was that if you're not from California, and you fill out the survey, please use the comment section to indicate your home state. For California licensing he needs to track his state residents per law requirement for pest management.
