“…Organic arsenical herbicides were introduced in the 1950s, with monosodium methyl arsenate (MSMA) becoming the most popular organic arsenical herbicide due to its cost, effectiveness, and lower toxicity compared with lead arsenate (USEPA, 2006). Currently, MSMA is commonly used for weed control in cotton and on turf and lawn (Busey, 2004). As of 2006, there were over 90 end-use products containing MSMA on the market, and over 3000,000 pounds were applied per year (USEPA, 2006).…”

Arsenic Retention in Foliage and Soil after Monosodium Methyl Arsenate (MSMA) Application to Turfgrass

et al. 2014

Monosodium methyl arsenate (MSMA) is a commonly used herbicide for weed control in turfgrass systems. There is concern that arsenic from applied MSMA could leach to groundwater or run off into surface water, thereby threatening human and ecosystem health. The USEPA has proposed a phase-out of the herbicide but is seeking additional research about the toxicity and environmental impacts of MSMA before establishing a final ruling. Little research has systematically investigated MSMA in field-based settings; instead, risks have been inferred from isolated field measurements or model-system studies. Accordingly, the overall goal of this study was to quantify the fate of arsenic after MSMA application to a managed turfgrass system. After MSMA application to turfgrass-covered and bareground lysimeters, the majority of arsenic was retained in turfgrass foliage and soils throughout year-long experiments, with 50 to 101% of the applied arsenic recovered in turfgrass systems and 55 to 66% recovered in bareground systems. Dissolved arsenic concentrations from 76.2-cm-depth pore water in the MSMA-treated soils were consistently <2 μg L, indistinguishable from background concentrations. As measured by adsorption isotherm experiments, MSMA retention by the sandy soil from our field site was markedly less than retention by a washed sand and a clay loam. Collectively, these results suggest that under aerobic conditions, minimal arsenic leaching to groundwater would occur after a typical application of MSMA to turfgrass. However, repeated MSMA application may pose environmental risks. Additional work is needed to examine arsenic cycling near the soil surface and to define arsenic speciation changes under different soil conditions.

“…In tropical areas, the 12‐mo growing season reduces the efficacy of goosegrass control by preemergence herbicides (Wiecko, 2000). Postemergence herbicides are not always effective in killing mature goosegrass plants and may weaken the turfgrass (Busey, 2004). There are no cultural practices reported for control of goosegrass (Busey, 2003).…”

Goosegrass (Eleusine indica L.) is a serious weed in traffi cked areas of bermudagrass (Cynodon spp.) golf and sports turf. Th e objective of this study was to evaluate soil compaction and canopy cover as determinants of goosegrass competition in bermudagrass turf in sand soil. Goosegrass cover, plant density, and soil penetration resistance (SPR) were measured in traffi c and notraffi c plots in bermudagrass golf course tees and sports fi eld foul areas. Goosegrass plant density and cover were larger in traffi c plots compared with no-traffi c plots. Soil penetration resistance increased only at 5.0 cm depth due to traffi c, while other soil properties including bulk density measured in golf course tees showed no eff ect from traffi c. Two experiments measured the eff ect of controlled soil compaction on root and shoot dry weight of goosegrass and bermudagrass in containers. Th e fi rst experiment evaluated eff ects of three soil compaction levels (1.14, 1.24, 1.33 g cm -3 bulk density) on goosegrass and bermudagrass grown separately. Th e second experiment evaluated eff ects on the two species grown together in competition, from two soil compaction levels (1.07 and 1.26 g cm -3 bulk density), two N application rates (48 and 96 kg ha -1 mo -1 ), and two mowing heights (1.3 and 2.5 cm). Th e second experiment also evaluated goosegrass seedling emergence and tiller numbers. When species were grown separately, bermudagrass root and shoot dry weight showed no eff ect from soil compaction, but goosegrass root weight was reduced. When species were grown together, bermudagrass root weight was reduced by compaction, but goosegrass was not aff ected. Goosegrass seedling emergence was reduced 58% by high mowing height, which paralleled an increase in bermudagrass canopy cover based on shoot dry weight. Canopy cover, not compaction, more readily explained the competition and infestation of goosegrass in traffi cked areas in sand soil.

“…This herbicide combination also causes a significant reduction in turfgrass quality when applied to mature common bermudagrass types (3,4,7). Although metribuzin + MSMA is used to control goosegrasss in established bermudagrass (2), the level of injury observed on seedling bermudagrass would make this an unacceptable combination to use during the first few weeks of establishment.…”

“…The sulfonylurea herbicides have shown excellent herbicidal activity against a range of cool‐season grasses and sedges (15) and will be a safe option to use on seedling bermudagrass turf. Foramsulfuron has also shown to have good activity against goosegrass (2) and will be a much safer option during seedling establishment than metribuzin + MSMA or diclofop (6).…”

Seeded bermudagrass (Cynodon dactylon L. Pers.) cultivars are rapidly gaining popularity in the turfgrass industry. Management programs need to be developed for the proper establishment and maintenance of these seeded cultivars. The objective of this study was to determine the tolerance of seedling ‘Riviera’ bermudagrass to a range of postemergence herbicides. Herbicide treatments were applied at 2 and 4 weeks after emergence and included metribuzin + MSMA, triclopyr + clopyralid + MSMA, clopyralid + MSMA, flazasulfuron + MSMA, foramsulfuron + MSMA, trifloxysulfuron‐sodium + MSMA, quinclorac + MSMA, 2,4‐D + dicamba + mecoprop + MSMA, and quinclorac. Herbicide injury and turfgrass coverage rates were monitored for 4 weeks after treatment. Treatments that caused significant injury to the seedling turf included metribuzin + MSMA and triclopyr + clopyralid + MSMA. Most of the herbicide combinations tested in these trials caused some level of turfgrass injury, but this injury was generally short‐lived and did not significantly reduce the rate of turfgrass coverage. The results of this study indicate that a range of herbicide combinations can be safely used on seedling bermudagrass to control problematic weeds during establishment.
