| Abstract/Contents: | Studies have shown "Acclaim" (fenoxaprop-ethyl) gave excellent control of crabgrass. "Acclaim 1EC is a postemergence herbicide with translocation properties. Although it will translocate within the plant from the point of contact to meristematic tissue, it will not translocate from one tiller to another tiller on the same plant. Therefore, in controlling crabgrass with more than one tiller, it is essential to get excellent coverage of the plant's leaf surface with the herbicide. Visual symptoms of crabgrass control are expressed as a chlorosis, 4 to 10 days after application, followed within 12 to 21 days after application of a reddening or purpling of the leaves and eventual death of plant tissue. Since Acclaim has no effect on broadleaf weeds, it would be desirable to tank mix Acclaim with broadleaf herbicides. Tank-mix treatments of Acclaim and broadleaf herbicides were initiated to determine the effect of several herbicide combinations on crabgrass control. Acclaim alone at 0.18 lb. a.i./A gave excellent crabgrass control. However, when tank mixed with Harmony herbicide (DPX-M6316) the efficacy was reduced. Studies have shown there was a general trend toward reduced crabgrass control with all broadleaf herbicides; however Trimec was the only treatment that was statistically different from the Acclaim alone treatment. Another study showed that Acclaim at 0.18 or 0.25 lb. a.i./A gave greater than 95% control of crabgrass. HOE 46360, the single most active isomer of Acclaim, also provided excellent crabgrass control; however, it was observed to be more phytotoxic to Kentucky bluegrass than Acclaim. Phytotoxicity could be reduced with the use of Tank mixed N and Fe. In another 1988 study, tank mixed Acclaim + Turflon Amine statistically showed a reduction in crabgrass control. Other research contradicts this. More research is needed." |
