Abstract

Multiple applications of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] during the winter, spring, and summer were evaluated for bahiagrass (Paspalum notatum F.) control in centipedegrass [Eremochloa ophiuroides (Munro) Hack.]. Single and repeated atrazine, metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazine-5(4H)-one], and methazole [2-(3,4-dichlorophenyl)-4-methyl-1,2,4-oxadiazolidine-3,5-dione] treatments were applied in the spring for common lespedeza [Lespedeza striata (Thunb.) H. & A. ‘Kobe’] control in centipedegrass. Atrazine at 2.2 kg/ha in two (July + August) or three (January + April + May, April + May + July, or May + July + August) applications controlled bahiagrass without injuring centipedegrass turf. In most instances repeated treatments were needed a second year for consistent control of 98 to 100%. A single treatment of atrazine at 2.2 kg/ha, metribuzin at 0.6 kg/ha, or methazole at 1.1 kg/ha satisfactorily controlled emerged common lespedeza in centipedegrass turf. None of the treatments injured centipedegrass. When atrazine was applied to actively growing centipedegrass, the turf had a darker green color than untreated turf. This usually occurred within a month after treatment and lasted for 3 to 4 weeks.
