| Abstract/Contents: | "Complete control of annual bluegrass (Poa annua L.) at all levels of P and at both planting dates was obtained with a,a,a,-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) at 2 lb/A. For both planting dates, high levels of P reduced the effectiveness of both calcium arsenate (CaAs) and to a small degree dimethyl 2,3,5,6-tetrachloroterephthalate (DCPA). On a plant count basis, O-(2,4-dichlorophenyl)O-methyl isopropylphosphoramidothioate (DMPA) was more effective than N-(2-mercaptoethyl) benzenesulfonamide S-(O,O,-diisopropyl phosphorodithioate) (bensulide) for the control of annual bluegrass. In the field, injury to bentgrasses (Agrostis palustris Huds.) from preemergence herbicides generally was specific to one or two varieties. Washington bentgrass was severely injured from a 12-lb/A application of 1-(2-methylcyclohexyl)-3-phenylurea (siduron)." |
