Abstract

Selected herbicides were evaluated for control of large crabgrass [Digitaria sanguinalis (L.) Scop.] and goosegrass [Eleusine indica (L.) Gaertn.] in planted ‘Tifway’ bermudagrass (Cynodon sp.). The most effective treatment technique was sequential treatments of DCPA (dimethyl tetrachloroterephthalate) at planting followed with two applications of MSMA (monosodium methanearsonate) + 2,4-D [(2,4-dichlorophenoxy) acetic acid] which controlled 95% of the weeds and permitted bermudagrass to form a 96% ground cover in 22 weeks. Other treatments, listed in order of decreasing effectiveness were a single application of oxadiazon [2-tert-butyl-4-(2,4-dichloro-5-isopropoxyphenyl)-δ2-1,3,4-oxadiazolin-5-one], pronamide [3,5-dichloro-N-(1,1-dimethyl-2-propynyl)-benzamide] applied in two applications and MSMA + 2,4-D in two applications.
