| Abstract/Contents: | "Commercially available preemergence herbicides do not consistently control weeds in turfgrasses satisfactorily in the Southeast. New herbicide tests to determine if weed control could be improved were conducted on several soil types over a 3-year period. Several herbicides were applied in early spring and evaluated for the control of large crabgrass (Digitaria sanguinalis L. Scop) in bermudagrasses [Cynodon dactylon (L.) Pers.] and Kentucky bluegrass (Poa pratensis L.) turf or they were applied in early fall and evaluated for the control of annual bluegrass (Poa annua L.) and other winter annuals in a bermudagrass turf. Soil types were Cecil s1 and Cecil sc1 (Typic Hapludult), Appling loamy sand and Appling sc1 (Typic Hapludult), Madison sc1 (Typic Hapludult), Hatboro 1 (Typic Fluvaquents), and Davidson sc1 (Rhodic Paleudult). Oxadiazon [2-tert-butyl-4-(2,4-dichloro -5-isopropoxyphenyl)-Δ2-1,3,4-oxadiazolin-5-one] applied in early spring at 4.5 kg/ha was better than with other herbicides tested for large crabgrass control. Oxadiazon was the only herbicide that consistently controlled large crabgrass at all locations. Parsley-piert (Alchemilla microcorpa Boissier Reuter), a broadleaf winter annual not previously reported, was controlled satisfactorily when oxadiazon was applied preemergence in the fall. No other herbicide controlled parsley-piert as well as oxadiazon." |
