Kudzu eradication trials with new herbicides

Informally Refereed

Abstract

Two screening studies in Georgia tested new herbicides as potential eradicators of kudzu (Pueraria lobata (Willd.) Ohwi). One study was conducted on a Coastal Plain and the other on a Piedmont site. Tordon 101 was applied as the standard. Those herbicides which are currently labeled for forest land site preparation and which gave control comparable to Tordon 101 (a-0.05) were Tordon K at 4 qt/A and Arsenal Applicator Concentrate at 6 qt/A, Lower rates of Arsenal, Oust + Roundup rates up to 6 oz + 2 qt/A, and Escort rates up to 8 oz/A did not yield effective control, Spike sow, a noncrop herbicide, gave control comparable to Tordon 101 when applied at rates of 4 and 6 lb product/A, An experimental herbicide, Lontrel at 2.64 qt/A, gave statistically less control than the Tordon standard. Another experimental formulation, Escort, in combination with Roundup at 1 oz f 1 qt, gave good control and appears promising for controlling kudzu invading pine plantations.
