Abstract

Kudzu control treatments using 15 herbicides at 1 and 2 rates were tested at six locations in Georgia and Alabama. Treatments and retreatments occurred over a 2-year period. Tordon® 101 Mixture at 2 gal/acre was the most cost-effective treatment, averaging about $77 per acre for herbicide costs. Tordon® 10K Pellets (presently not being manufactured) gave slightly better control, but at 3 times the cost. Both herbicides reduced kudzu coverage to 1% or less. Banvel® gave greater than 95% control with an average cost of $220 per acre. All treatments decreased in effectiveness as patch age increased and as soils became more stony.

Tree-draped kudzu was controlled using a 1% solution of Garlon® in diesel oil applied only to vines before foliage developed. Tordon® 101 Mixture and Banvel® 720 were sprayed at 1 gal/acre on kudzu growing under and on 35 ft pines without pine mortality . Several treatments at this rate spaced at east 2 growing seasons apart will be required to eradicate kudzu that is invading pine stands of this size.
