Abstract/Contents:Preventing broadleaf weed establishment in turfgrass with herbicides was the purpose of this article. For several years preemergent herbicides have successfully been used in turf to prevent crabgrass. Little information is available on their value under turfgrass conditions for preventing broadleaf weeds. A test was initiated in the spring of 1969 on a five year old lawn composed of bluegrass and fescue. Eleven herbicide treatments were applied on May 6 to plots measuring 4 x 12 feet and replicated six times. Nine days later, dandelion, broadleaf plantain and mouseear chickweed seed was separately spread over specific portions of each plot. Turf injury data was taken during the season and weed counts were made in early September. Tentative results indicate that plots treated with DCPA at 10 lb ai/A, DCPA + sesone (9 + 2.7 lb) and DMPA (15 lb) caused a reduction in fescue. Good control of plantain was produced by bandane (35 lb), DCPA, DCPA + sesone, DMPA, picloram (1/8 lb), nitralin (2 lb) and tri-calcium arsenate (209 lb). Plots treated with DMPA, picloram, siduron (12 lb) and tri-calcium arsenate showed a reduction in the number of dandelions. Treatments which showed little effect on plantain and dandelion establishment were benefin (2 lb), bensulide (10 lb) and terbutol (10 lb). All materials under test, with the exception of bensulide, produced a reduction in the number of mouseear chickweed.
