| Abstract/Contents: | "Mesotrione effectively controls 1 to 2 tiller smooth crabgrass in spring, but subsequent germination of crabgrass in summer may warrant tank-mixtures with preemergence herbicides for season-long control. Field experiments were conducted from April to September 2013 in Griffin, GA to evaluate mesotrione and prodiamine combinations, compared to dithiopyr and prodiamine alone, for postemergence and residual control of smooth crabgrass in tall fescue. Treatments were applied to an irrigated 'K-31' tall fescue lawn maintained at 7.5-cm mowing height with clippings returned. Mesotrione plus prodiamine treatments were made with a pre-packaged formulated mixture (4SC) at 0.56 kg a.i. ha-1 at three timings including: preemergence followed by (FB) 8 weeks after treatment (WAT), multi-leaf postemergence FB 4 WAT, or 1 to 2-tillered postemergence FB 2 WAT. Prodiamine alone was applied at the aforementioned preemergence program at 0.42 FB 0.42 kg a.i. ha-1, or sequentially at multi-leaf postemergence FB 4 WAT. Dithiopyr was also applied sequentially at 0.28 kg a.i. ha-1 at the aforementioned preemergence program, or singly at 0.56 kg a.i. ha-1 at the two postemergence timings. Smooth crabgrass cover increased over time in the nontreated plots, and averaged 54% cover by September. All mesotrione + prodiamine treatments controlled smooth crabgrass >97% within 3 weeks after applications, and control was >90% on September 8. Sequential prodiamine treatments alone controlled smooth crabgrass 71% and 61% when applied at the preemergence and early postemergence timing, respectively. All dithiopyr treatments provided 78 to 83% control of smooth crabgrass in July, but control declined to 90%) preand postemergence control of smooth crabgrass in tall fescue." |
