Callahan's Kudzu Guard is designed to prevent kudzu from climbing up utility pole guy wires. After installation on a pole at the Coalition test site, kudzu immediately attempted to climb the wire shown in the first photograph, but was blocked by the guard (June 2005). By the middle of August the vine was still under control, unlike a control also shown in the second photograph, which is covered in vine. Note that the pole has a guard wrapped around it (the black band at the base of the pole), and it is also free of vine.
One year later the unprotected guy wire has an even more abundant kudzu load than in the previous year. The protected wire is kudzu-free, as is the protected pole. August 2006.
