Plant and Soil Sciences senior researcher Jim Taylor spent Tuesday on the north farm amid a 30-day old plot of Bermuda grass, but not to see if the grass really is greener on the other side of the fence. His efforts are part of a joint effort with research partner DuPont Chemicals to study the effectiveness of the company's new herbicide, Pastora, in reducing weed content when establishing a field for hay production. The study is expected to conclude by early fall.
