“…Other research indicated Imprelis SL was an excellent new herbicide for use in turfgrass (Beck et al, 2014), and our research showed it also had minimal to no volatility. Unfortunately, during the course of our research Imprelis SL was implicated in multiple cases of tree damage, apparently caused by root uptake of the herbicide, and has been removed by the manufacturer from the turfgrass market (V.B.…”

Laboratory and field studies were conducted in 2010 and 2011 to evaluate the volatility of commonly used turfgrass broadleaf herbicides when applied to tall fescue (Lolium arundinaceum Schreb.). Herbicides were applied at the highest label rate for dandelion (Taraxacum officinale G.H. Weber ex Wiggers) control. Turfgrass flats treated with herbicides were placed in enclosures containing tomato plants. In laboratory experiments, tomatoes exposed to turfgrass treated with products containing amine formulations of synthetic auxin herbicides exhibited minimal injury, but exposure to products containing low‐volatile ester formulations caused significant negative effects on tomato quality, epinasty, and callus formation. Generally, products containing low‐volatile ester formulations of synthetic auxin herbicides exhibited less volatility, compared to 2,4‐D butyl ester (volatile standard). A subsequent field study corroborated the laboratory results, although injury symptoms were less severe. Turfgrass managers should avoid herbicides containing low‐volatile ester formulations when vulnerable non‐target plants are nearby, and/or when environmental conditions such as high temperature favor volatility.

“…Triclopyr provided effective and consistent ground ivy control (78–98% reduction) in Kentucky bluegrass in past research (Beck et al, 2014; Kohler et al, 2004b; Reicher and Weisenberger, 2007). Fluroxypyr was also effective against ground ivy (87% reduction), although it was less effective than triclopyr (98% reduction) (Reicher and Weisenberger, 2007).…”

“…In Michigan, Hanson and Branham (1988) observed that mid‐to‐late October herbicide applications resulted in greater levels of dandelion control than September applications when evaluated the following spring. Previous reports have also documented the efficacy of fall herbicide applications for ground ivy control (Beck et al, 2014; Kohler et al, 2004b; Reicher and Weisenberger, 2007). Fall herbicide applications from 1 September to 1 November provided greater ground ivy control than applications made after 15 November in West Lafayette, IN (Reicher and Weisenberger, 2007).…”

“…Ground ivy control improved when 2,4‐D and triclopyr were tank‐mixed with other herbicides or with each other (Olson and Wright, 1988; Vrabel, 1987). More recent research found that aminocyclopyrachlor and metsulfuron applied alone or in tank mixtures with sulfentrazone or carfentrazone can control ground ivy (Beck et al, 2014; Brosnan et al, 2012). Ground ivy control from quinclorac is variable in the literature and may be dependent on the population (Calhoun and Baird, 1999; Czarnota et al, 2001, Kohler et al, 2004b; Neal and Senesac, 1991).…”

Ground ivy (Glechoma hederacea L.) is a creeping perennial broadleaf species that is difficult to control in turf. The efficacy of spring herbicide applications has received limited investigation. Further, comparisons between commonly used and effective herbicide treatments are limited. Field experiments were conducted to determine the influence of herbicide selection and fall and spring application timings on the control of ground ivy across three separate environments located across Indiana and Tennessee. Herbicides containing 2,4‐D, fluroxypyr, triclopyr, iodosulfuron, thiencarbazone, and aminocyclopyrachlor or mixtures of these active ingredients had the greatest control of ground ivy (>53%) at both timings. With the exception of metsulfuron and fluroxypyr, most of the herbicides provided consistent ground ivy control when applied in either the fall or the spring. Differences in ground ivy control between herbicides were much greater than differences between spring and fall application timings. This research indicates that proper herbicide selection has a larger influence on ground ivy control than application timing.

“…Carfentrazone-ethyl (shoot-absorbed) plus 2,4-D (root-absorbed) plus dicamba (root-and shoot-absorbed) plus mecoprop (mostly root-absorbed) (Speedzone 2.2L; PBI Gordon, KS City, MO) is effective for the control of many broadleaf weeds and goosegrass-the only grassy weed listed on the label (http://www.cdms. net/ldat/ld61R001.pdf) (Beck et al, 2014). The site of herbicide uptake is an important factor to consider when developing techniques to reduce turfgrass injury.…”

Summer annual grassy weeds such as goosegrass (Eleusine indica L. Gaertn.) continue to be problematic to control selectively with postemergence (POST) herbicides within turfgrass stands. In recent years, reduced performance by certain herbicides (e.g., foramsulfuron), cancellation of goosegrass-specific herbicides (e.g., diclofop-methyl), and cancellation and/or severe use reductions of other herbicides [e.g., monosodium methanearsonate (MSMA)] have limited the options for satisfactory control and maintenance of an acceptable (≤30% visual turfgrass injury) turfgrass quality. Currently available herbicides (e.g., topramezone and metribuzin) with goosegrass activity typically injure warm-season turfgrass species. The objectives of this research were to evaluate both ‘Tifway 419’ bermudagrass [Cynodon dactylon (L.) Pers. ×Cynodon transvaalensis Burtt-Davy] injury after treatment with POST herbicides, and to determine whether irrigating immediately after application reduces turfgrass injury. Treatments were control (± irrigation); topramezone (Pylex 2.8C; ± irrigation); carfentrazone + 2,4-D + dicamba + 2-(2-methyl-4-chlorophenoxy) propionic acid (MCPP) (Speedzone 2.2L; ± irrigation); carfentrazone + 2,4-D + dicamba + MCPP in combination with topramezone (± irrigation); metribuzin (Sencor 75DF; ± irrigation); mesotrione (Tenacity 4L; ± irrigation); simazine 4L (±irrigation); and mesotrione + simazine (± irrigation). Irrigated treatments were applied immediately with a hand hose precalibrated to apply 0.6 cm or 0.25 inch (≈6.3 L). Visual turfgrass injury for combined herbicide treatments for the irrigated plots was 6% 4 days after treatment (DAT), 12% 1 week after treatment (WAT), 17% 2 WAT, and 6% 4 WAT, whereas nonirrigated plots had turfgrass injury of 14% at 4 DAT, 31% 1 WAT, 35% 2 WAT, and 12% 4 WAT. Irrigated pots had normalized differences vegetative indices (NDVI) ratings of 0.769 at 4 DAT, 0.644 at 1 WAT, 0.612 at 2 WAT, and 0.621 at 4 WAT, whereas nonirrigated plots had the lowest (least green) turfgrass NDVI ratings of 0.734 at 4 DAT, 0.599 at 1 WAT, 0.528 at 2 WAT, and 0.596 at 4 WAT. These experiments suggest turfgrass injury could be alleviated by immediately incorporating herbicides through irrigation.
