| Abstract/Contents: | Nine studies, over a four-year period, were conducted to evaluate herbicides for the selective control of dandelion, mouseear chickweed and white clover in cool-season turfgrass. Standard and newer herbicides were tried alone and in various combinations. Attempts were made to determine the influence of tank mixes, seasonal applicaation and adjuvants on herbicide efficacy. There was variability in the results from one test to another. Herbicide applications made in October provided results that were similar to those applied in May or June. None of the herbicides applied alone provided consistent control of the three weeds. 2,4-D and R-40244 provided better dandelion control but R-40244 caused some grass injury. The following materials applied alone were more effective on clover and/or chickweed than on dandelion: dicamba, dichlorprop, mecoprop, silvex, Vel-4207, triclopyr and dikegulac. The latter two herbicides caused some grass injury. Combinations of 2,4-D with one or more of the following -- dicamba, dichlorprop, mecoprop, silvex or Vel-4207 did provide improved broad spectrum control. Some of the 2,4-D plus dichlorprop granular combinations did not perform as well as spray applications. The efficacy of the 2,4-D plus dicamba combination was not enhanced by the use of adjuvants such as AL-1448, PACE and X-77. Tank mixing a postemergence crabgrass herbicide such as DSMA and/or a preemergence crabgrass herbicide such as bensulide, DCPA and siduron with the broadleaf weed combination of 2,4-D with either dicamba or silvex did not provide any problem in spray application. Except for a few tank mixes they provided weed control similar to that which would be obtained if the materials were applied separately. Many broadleaf herbicide combinations provided a reduction in crabgrass. Three to five monthly applications of 2,4-D, dicamba or a combination of both did not cause objectionable grass injury while in some situations weed control was greater and of a longer duration. |
