Abstract/Contents:Presents a study to "Determine the timing and rate of herbicide combinations needed for effective crabgrass control in tall fescue." Results indicate that "none of the herbicides applied alone or as tank-mix treatments controlled crabgrass effectively throughout the summer in 1994...Pendimethalin applied at 2.0 lb ai/A on May 2 controlled 85% crabgrass by late July, but the control was reduced to 65% within 4 weeks. In this study, the control was higher when pendimethalin was applied on May 2 than on April 5. There was no advantage for tank-mixes of pendimethalin and Acclaim, when compared with pendimethalin alone on May 2." Also presents a study to "determine if tank-mixes of MSMA and Dimension would provide a higher and longer period of consistent crabgrass control than each herbicide applied alone, and to determine if lower herbicide rates could be used in tank-mixes." Results indicate that "crabgrass control in common bermudagrass during 1993 and 1994 was consistently higher from tank-mixes of MSMA and Dimension than from each applied alone." Also presents a study to "determine the effects of cultivar competition with crabgrass treated with PRE herbicides at reduced rates."
