| Abstract/Contents: | "Two experiments were conducted during 1985 (one pre- and one post-emergence) to evaluate various herbicides for the control of smooth crabgrass [Digitaria ischaemum (Schreb.) Michx.] in cool season turfgrasses. The preemergence test was conducted to assess experimental materials and some combinations of products against the control achieved through the use of commercial standards. Acceptable control was found for all treatments. Benefin, benefin plus trifluralin, all rates of prodiamine, bensulide plus devrinol, DCPA, pendimethalin, pendimethalin plus devrinol, and all rates and formulations of bensulide controlled smooth crabgrass at least 90 percent. The postemergence test was initiated to: 1) evaluate experimental materials (EH 850 and fenoxyprop-ethyl) alone and in combination, 2) assess the effects of combination broadleaf herbicides on the efficacy of fenoxyprop-ethyl, 3) compare commercial standards alone and in combination with broadleaf herbicides. Acceptable control (85%) was found for fenoxyprop-ethyl applied at 0.22 and 0.28 kg ai/ha, fenoxyprop-ethyl combined with EH 850 at 0.28 and 8.96 kg ai/ha respectively, fenoxyprop-ethyl with 2,4-D, MCPP, and dicamba at 0.39, 1.23, 0.56 and 0.11 kg ai/ha respectively, and for MSMA at 2.24 kg ai/ha. All rates of EH 850 and the combination of EH 850 with MSMA and EH 850 with the low rate of fenoxyprop-ethyl did not provide acceptable control. Control from application of 2,4-D, MCPP, dicamba and MSMA was rated at 82 percent. When the two lower rates (0.17 and 0.28 kg ai/ha) of fenoxyprop-ethyl were tank mixed with 2,4-D, MCPP, and dicamba, control was not acceptable. Apparently, antagonism occurred when these chemicals were mixed which then decreased efficacy on smooth crabgrass." |
