| Abstract/Contents: | "Turfgrass management recommendations to professional lawn care contractors and homeowners often include mowing at the tallest recommended height and providing adequate nitrogen fertility to maximize turfgrass vigor. These recommendations are based on the premise that a vigorous turf will be better suited to compete with diseases, weeds and insects and will be better able to recover from physical damage. Weeds are usually a symptom of a weakened turf. Without proper cultural management, the weed control provided by herbicides will be at best, temporary. This study was conducted from 1998 to 2004 to examine the interaction of mowing height, fertility, and postemergence herbicide treatment and their effect on broadleaf weed persistence. Broadleaf weed populations were quantified in May and September of each year of the experiment. Plots were maintained at 5 or 10 cm mowing height, and received either 0 or 150 kg N ha-1 yr-1. Postemergence broadleaf herbicide treatments were made in October 1998 and 2001. Standard rates of 2,4-D ((2,4-dichlorophenoxy)acetic acid) + mecoprop ((±)-2-(4-chloro-2-methylphenoxy)propanoic acid) + dicamba (3,6-dichloro-2-methoxybenzoic acid); or triclopyr ([3,5,6-trichloro-2-pyridinyl)oxy]acetic acid) + clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) provided commercially acceptable control (i.e., >95%) of dandelion (Taraxacum officinale Weber in Wiggers) and white clover (Trifolium repens L.) the following spring. The re-infestation of white clover and dandelion was slowest in the N-treated plots and those treated with triclopyr + clopyralid. Non-treated (receiving no herbicide), non-fertilized plots mowed at 10 cm had the highest populations of white clover. Non-treated plots maintained 10 cm in conjunction with the fertilizer program reduced white clover and dandelion populations by 75 percent in the fifth and sixth years of the study as compared to the non-treated, non-fertilized, 5 cm mowing height plots. Fertlized plots maintained at either 5 or 10 cm had the slowest re-infestation of broadleaf weeds after the postemergence broadleaf herbicide applications." |
