KUDZU: where did it come from? And how can we stop it?
The introduction of Pueraria lobata (a vine from China) into SE USA is described. Originally planted as an ornamental, for forage and to prevent erosion, it is now estimated to infest 2 million acres. Control is difficult because of the large root tubers. Registered herbicides used for kudzu control are tabulated, together with information including rate and cost/acre. Soil active herbicides with the active ingredients picloram and dicamba are recommended as being the most effective, although repeated applications may be necessary. Overgrazing for 2-3 yr may also be effective.
