Effect of Benefin and DCPA on Overseeded Grasses Maintained as Putting Greens

  • G. E. Coats (a1), C. Y. Ward (a1) and E. L. McWhirter (a1)


Overseeded rough bluegrass (Poa trivialis L. ‘Danish common’) and Italian ryegrass (Lolium multiflorum Lam. ‘Gulf’) maintained under putting green conditions were more susceptible to benefin (N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine) and DCPA (dimethyl tetrachloroterephthalate) than creeping bentgrass (Agrostis palustris Hud. ‘Penn-cross’), red fescue (Festuca rubra L. ‘Dawson’), or perennial ryegrass (Lolium perenne L. ‘Medalist II’). February applications of 1.68 or 3.36 kg/ha of benefin and 6.72 or 13.44 kg/ha of DCPA caused significantly more discoloration and reductions in density than equivalent rates applied in March or April. Benefin was more injurious than DCPA to all overseeded species as judged by quality or density. DCPA caused significant delays in the breaking of dormancy of bermudagrass [Cynodon dactylon (L.) Pers. ‘Tifdwarf’].
