| Abstract/Contents: | "Ground ivy (Glechoma hederacea L.) and healall (Prunella vulgaris L.) are creeping perennial weeds which commonly infest cool-season turf and are difficult to control with currently available herbicides. Greenhouse and field tests were conducted to evaluate two herbicide strategies for controlling these species. Isoxaben at 0.6, 1.1, and 2.2 kg/ha, and quinclorac (BAS 514) at 0.4, 0.6, and 0.8 kg/ha were evaluated alone and in combination with other synthetic auxin herbicides. In general, isoxaben was more effective in field tests than in greenhouse tests; whereas, synthetic auxins such as 2,4-D and triclopyr, were more effective at lower rates in the greenhouse than in the field. In the greenhouse, isoxaben at 2.2 kg/ha provided only 35% and 50% control of ground ivy and healall, respectively. However, in the field, up to 99% ground ivy and 85% healall control was obtained. The local use-rates of 2,4-D + triclopyr amine OR clopyralid + triclopyr amine, provided only 10 to 20% healall control, but when mixed with 1.1 kg/ha of isoxaben, 80% to 85% control was obtained. Quinclorac efficacy in field and greenhouse tests were similar for ground ivy; but, for healall, greenhouse results were superior. In field tests, quinclorac applied alone at 0.8 kg/ha controlled healall; but, the speed of control was improved by tank mixing with 2,4-D. Ground ivy was not controlled by quinclorac applied alone, but was controlled by the tank mix with 2,4-D. From these tests, two viable strategies for improved control of ground ivy and healall in cool-season turf are: quinclorac + 2,4-D at 0.8 + 1 kg/ha, OR isoxaben + synthetic auxin herbicides such as 2,4-D + triclopyr or clopyralid + triclopyr. Further research is needed to opitmize the tank mix ratios." |
