Abstract

Methazole [2-(3,4-dichlorophenyl)-4-methyl-l,2,4-oxadiazolidine-3,5-dione], metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one], and combinations of MSMA (monosodium methanearsonate) with either methazole or metribuzin were applied to bare ground at 0, 1, 2, and 4 weeks before planting with bermudagrass [Cynodon dactylon (L.) Pers. ‘Common’] as sprigs, stolons, and seed. In most instances, the growth of newly planted bermudagrass was as good or better from combination of MSMA (2.2 kg/ha) with either methazole or metribuzin at 0.1 kg/ha than with methazole or metribuzin applied alone at higher rates. MSMA + methazole can be applied safely on day of planting with sprigs and seed, but a 1-week interval between treatment and planting was needed with stolons in 1 of 2 yr. The MSMA + metribuzin combination can also be applied safely to sprigged bermudagrass on day of planting, but a 1-week interval was needed between treatment and planting with stolons and a 2-week interval between treatment and planting with seed to insure minimum bermudagrass injury.
