| Abstract/Contents: | "Field and laboratory experiments were conducted in New Jersey to investigate the influence of spray adjuvants on foliar absorption and efficacy of bispyribac-sodium on annual bluegrass, creeping bentgrass, and perennial ryegrass. In laboratory experiments on annual bluegrass, 14C-bispyribac-sodium without an adjuvant had 25% foliar absorption by 8 h after treatment, whereas absorption increased to 45, 46, and 75% when applied with crop oil concentrate, nonionic surfactant, and methylated seed oil, respectively. In creeping bentgrass fairways, sequential bispyribac-sodium applications at 37 g ai/ha with spray adjuvants controlled annual bluegrass similarly to 74 g ai/ha applied sequentially without adjuvants. In perennial ryegrass, treatments with methylated seed oil and nonionic surfactant required 25 and 41% lower bispyribac-sodium rates, respectively, to obtain annual bluegrass control levels comparable to bispyribac-sodium rates without adjuvants. Spray adjuvants did not exacerbate turf-grass discoloration from bispyribac-sodium. Overall, spray-adjuvant use with bispyribac-sodium may allow practitioners to reduce application rates and enhance efficacy for annual bluegrass control." |
