Herbicide tests for kudzu eradication.

Kudzu control treatments using 15 herbtreatments decreased in effectiveness as icides at 1 and 2 rates were tested at six locations in Georgia and Alabama. Treatments patch age increased and as soils became and retreatments occurred over a 2-year more stony. period. TordonQ 101 Mixture at 2 gal/acre Tree-draped kudzu was controlled using was the most cost-effective treatment, ava 1% solution of Garlo@4 in diesel oil applied eraging about $77 per acre for herbicide only to vines before foliage developed. Tordon 101 Mixture and Banvel 720 were costs. Tordon 10K Pellets (presently not being manufactured) gave slightly better sprayed at 1 gal/acre on kudzu growing control, but at 3 times the cost. Both herbiunder and on 35 ft pines without pine mortalit . tides reduced kudzu coverage to 1% or Y Several treatments at this rate spaced less. Banvel@ gave greater than 95% control at east 2 growing seasons apart will be with an average cost of $220 per acre. All required to eradicate kudzu that is invading pine stands of this size. 1Drscussion of herbicides in this paper does not constitute recommendation of their use or imply that uses discussed here are registered.
