There are other herbicides that can provide good post-emergence crabgrass control. A severe goosegrass infestation may indicate the need for aerification to alleviate compaction. Application timing is critical when choosing to treat pre-emergently. Goosegrass more so than crabgrass has a history of developing herbicide resistance if herbicides with the same mode of action are used in several consecutive years. Most post-emergence herbicides will not control seedlings that germinate after application (i.e., provide residual control). Below is a picture of Crabgrass. Multiple applications on 2- to 3-week intervals may be necessary to provide complete control. The best way to eliminate true Crabgrass is by thickening your lawn. Crabgrass and goosegrass will germinate through August in New Jersey. Applications can be made on a 30-day interval. New Jersey Agricultural Experiment Station Post-emergence herbicides commonly used to treat crabgrass and goosegrass are quinclorac and fenoxaprop. Post-emergence herbicide efficacy usually improves again in late August once plants mature and temperatures cool. See the product label for more information. Goosegrass is a tremendous problem in the transition zone and farther south since it germinates later than crabgrass, and many preemergence herbicides are less active on goosegrass than crabgrass. Crabgrass originated in Europe and Eurasia, and was brought to the US as a forage crop in 1849. Tank-mixing SpeedZone and Pylex will control multi-tiller goosegrass and eliminate bleaching symptoms caused by Pylex. I usually don't see it sprouting until late May or early June in Ohio. Crabgrass will germinate earlier in bare soil, particularly on south-facing slopes and near hardscapes, than in areas with good turfgrass cover. Goosegrass is a weedy grass that looks similar to crabgrass, but it's more difficult to control. Rutgers Cooperative Extension, a unit of the Rutgers New Jersey Agricultural Experiment Station, is an equal opportunity program provider and employer. Poor application uniformity, especially on slopes, is a common cause of pre-emergence herbicide failure. Best postemergence control of crabgrass and goosegrass is obtained when applied to plants with fewer than 4 tillers. In our research, this approach provided moderate goosegrass control. Most pre-emergence herbicides must be applied and watered into the soil before the weed seed germinates to be effective. Matthew Elmore, Assistant Extension Specialist in Weed Science. Are you gambling in your landscaping business? Posted by. For goosegrass control, the product label recommends a single application at 1.5 to 2.0 lb ai/A before crabgrass emergence and a second application at 1.5 lb ai/A 5 to 8 weeks later. See the label for information on fine fescue species. Broadleaf herbicides such as 2,4-D, MCPA, or MCPP applied within five days before or 21 days after a fenoxaprop application will reduce grass control. Pylex is extremely effective for goosegrass control and moderately effective against crabgrass. Fenoxaprop-ethyl won’t provide any broadleaf weed control on its own and should not be tank-mixed with phenoxy herbicides. When in soil solution, herbicides are also susceptible to degradation by soil microbes, which renders them ineffective for weed control. All major cool-season turfgrass species and zoysiagrass. Point of Collection Notice Both crabgrass and goosegrass are annual plants that cannot regrow if the crown (basal growing point) of the plant is removed. Learn about The Spruce's Editorial Process. Goosegrass germinates when soil temperatures reach 60°F, which is usually at least two weeks later than crabgrass. or annual bluegrass (Poa annua) are desired. Rutgers is an equal access/equal opportunity institution. Flower stems are upright with two or more fingerlike spikelets at the tip. Crabgrass typically begins to tiller and mature rapidly beginning in mid- to late June. A healthy and dense turfgrass canopy will reduce reliance on herbicides. are common annual grassy weeds that can be problematic on athletic fields, golf courses, residential and commercial lawns, and sod ... application will extend residual crabgrass species control and increase goosegrass control. After the 2-tiller stage, plants quickly become difficult to control, especially in bentgrass (Agrostis spp.) Protoporphyrinogen oxidase (PPO) inhibitor (WSSA Group 14). Goosegrass typically germinates 3 to 4 weeks after crabgrass. Do not apply to zoysiagrass. Up to 2.3 lb ai/A can be applied annually in tall fescue. The color is emerald green with older blades having a small bit of white on their damaged edges. Most pre-emergence herbicides are available as granular and sprayable formulations. During the tiller stage, the plant is defined by the number of tillers (stems). For example, Acclaim Extra will control leaf-stage crabgrass and goosegrass at 13 fl oz/A, but 28 fl oz/A are required to control 3-tiller and 4-tiller plants. The leaf blades are å_ inch wide and 2 to 10 inches long. You want your application down just prior to that. Organic post-emergence herbicides are typically non-selective and will be more effective at controlling small seedling weeds. Controlling plants that survive pre-emergence applications with post-emergence herbicides, or applying both a mitotic inhibiting pre-emergence herbicide and a pre-emergence herbicide such as oxadiazon (that has a different mode of action) will delay the onset of herbicide resistance. It is found in the lawn and landscape beds in the summer and is common in areas with compacted soil. Sequential applications are often required to plants at the 5-tiller stage and larger. They form a tight, spreading clump that can reach over 2 feet wide. Goosegrass is an annual grassy weed, similar in appearance to Crabgrass, except it is darker green and has more leaf blades, resembling spokes in a wagon wheel when viewed from above. Crabgrass has a rolled stem (rounded vernation) and lime green, coarse-textured leaves. Crabgrass and goosegrass are two weeds that have adapted to a wide range of growing conditions. Remember, though, that even though you’re using the same chemical to treat both, you’ll need to make two separate applications (one for crabgrass and one for goosegrass) because of the differences in their germination periods. Healthy soil is the foundation of a stunning landscape: Here’s, How to keep your landscaping business thriving during the pandemic. Post-emergence herbicides are formulated to kill weeds that have already germinated. Herbicide degradation triggers desorption of more herbicide from the soil. Do Not Sell My Personal Information, Chemical care: Controlling crabgrass and goosegrass, Industry roundup: ASV to increase production capacity by 30 percent, Echo launches 13 “game-changing” new products for 2021. “As a rule, both (liquid and granular) perform similarly because manufacturers have determined the proper spread rate and loading of the product on granules. “When soil temperatures hit that threshold again the following year, the cycle starts again and they germinate from seed,” Miller says. Kentucky bluegrass, perennial ryegrass, and tall fescue. “Many people historically apply product because they’ve been doing it for so long ‘at about this time.’ They think they’re getting product down before weeds begin to germinate, but this is unreliable,” Miller says. SpeedZone is labeled for goosegrass control at 4 to 5 pints/A but it will not control crabgrass. Lower rates will provide broadleaf weed control, higher rates are required for crabgrass control. All rights reserved. Industry roundup: Leavitt Machinery awarded as Top Performing Dealer for... Equipment roundup: John Deere announces L-Series backhoe upgrades, Helping clients achieve long term sustainability. The main difference between crabgrass and goosegrass is their timing of germination. Crabgrass (Digitaria spp.) It looks like grass until it grows tall enough to sprout a seed head. Copyright © 2020 Rutgers, The State University of New Jersey. Blades of crabgrass are between 1/4 of an inch to 1/3 of an inch wide, with a prominent mid-vein. Pylex will provide control of leaf stage goosegrass at 0.25 fl oz/A. Goosegrass is a summer annual grassy weed that is also known as silver crabgrass, even though it is not a type of crabgrass. Dithiopyr does not provide early post-emergence control of goosegrass or other weeds. Most herbicides listed below will also provide control of other summer annual grasses such as yellow and green foxtail (Setaria pumila and Setaria viridis, respectively) and barnyardgrass (Echinochloa crus-galli). For ex… Bermuda grass comes from African Savannah, and was brought into the US as a hardy and drought-tolerant crop in 1807. Product labels often provide more information on the sequential application strategy. Include a non-ionic surfactant. Goosegrass more so than crabgrass has a history of developing herbicide resistance if herbicides with the same mode of action are used in several consecutive years. Kathleen Connolly is a writer with a broad background covering landscaping and design. Combining a higher height of cut with proper fertilization will create a dense turfgrass canopy that will shade the soil and create a more difficult environment for weed seedlings to survive. Thus, when applying a post-emergence herbicide in June, July, or early August, consider including a pre-emergence herbicide unless you plan to seed in the autumn. Goosegrass is most easily identified by its whitish, flattened stem (folded vernation) and prostrate growth habit (Figures 1 and 4). Even though it’s sometimes referred to as nutgrass, it’s not a grass—it’s a sedge (a flowering plant to resembles grass). It can be easily distinguished from lawn grass by its clump-like form. “You almost have to make two applications in order to properly control the weeds.”. is an annual weed grass. Here is the second installment on maximizing control of goosegrass in warm-season fairways. He points out that the choice is all about convenience more than anything. “Companies have perfected the load and spread rate so that liquid and granular applications are similar – we don’t see a big difference.”, ©2020 Total Landscape Care A crabgrass plant can advance from the leaf stage to 3-tiller stage in just a few weeks during the summertime. Microtubule assembly inhibitor (WSSA Group 3). At that point, it is young and not as noticeable. Applications at 2.0 to 3.0 lb ai/A have provided significantly more goosegrass control than prodiamine and dithiopyr in our research. The methods on how to kill goosegrass range from cultural to herbicidal. Products listed below are safe on most cool-season turfgrasses, but always refer to the label for turfgrass tolerance information especially where fine fescue (Festuca spp.) Recommendations below assume conditions for active weed and turfgrass growth are present around the time of application. See the product labels for more information on controlling these and other grasses. Figure 2. These plants germinate in the spring and grow rapidly throughout the summer as warm-season (C4) plants, mature in late summer, and produce seed before dying at the first frost in autumn. Figure 1. Applying granular fertilizer with at least 0.25 lb/1000 ft, Protoporphyrinogen oxidase (PPO) inhibitor (WSSA Group 14) and synthetic auxin (WSSA Group 4). Crabgrass is typically a main target for pre-emergence herbicide applications.Photo: Syngenta. Effectiveness of most organic herbicides is highly dependent on environmental conditions, and often provide more control as relative humidity and air temperature increase. See the product label for more information on use before or after seeding, even if seeding was conducted the previous autumn. Generally speaking, crabgrass germinates at a soil temperature of 55 degrees Fahrenheit and goosegrass at 65 degrees Fahrenheit. Measuring about .5-inch up to 2 feet tall in perfect growing conditions and left untreated, it’s often confused with crabgrass. Goosegrass can be prevented in the lawn by applying a pre-emergent weed control in the spring. A few days later, another leaf (the first true leaf) will emerge and the plant is classified as a 1-leaf stage plant. Both crabgrass and goosegrass are tropical grasses that like hot, dry conditions and climates. In creeping bentgrass, multiple applications at 0.25 fl oz/A on a 2- to 3-week interval are recommended if tillered plants are observed. They’ve perfected the science,” Miller says. “Pre-emergents and fertilizer are routinely blended together,” Miller says. Do not apply SpeedZone to bentgrass maintained at 0.5" or lower in the summertime or bentgrass injury may result. “Warm-season turf is a tropical grass like crabgrass and goosegrass,” Miller says. Some of you will battle these weeds each growing season; for others – especially those of you in the Deep South – crabgrass and goosegrass can be a year-round problem. Smooth crabgrass and large crabgrass. Goosegrass and crabgrass are still relatively easy to control at the 1- to 2-tiller stage. Forsythia is an excellent phenological indicator for crabgrass germination. For example, dithiopyr and prodiamine are common pre-emergence herbicides with the same mode of action (mitosis inhibitor). For broadleaf and grassy weed control with fenoxaprop, use Last Call herbicide. See the product label for use on bentgrass mowed at 0.5 inches or less. Sequential application is another strategy to prevent failures, which divides the single application rate into two lower-rate applications. It is especially important to sweep the product off of sidewalks, roads, and other hardscapes to prevent runoff. Use caution when applying SpeedZone in the summertime as 2,4-D ester can volatilize and cause off-target damage to sensitive plants nearby. After germination when the plant first emerges from the soil, the first leaf is the coleoptile and the plant is in the seedling stage (Figure 5). Be aware that Pylex causes goosegrass and crabgrass leaves to appear bleached for 7 to 14 days after application before plants die (Figure 6). Growth stages of annual grassy weeds. In areas with a history of infestations that cannot be managed with cultural practices and mechanical removal alone, herbicides are an effective and economical option when applied at the proper time and rate. Another option is to choose a chemical control for these weeds that also contains a fertilizer. In the leaf stage, the plant is more susceptible to herbicides or can be easily removed by hand. There are many quinclorac-containing products that contain quinclorac at different rates. We are trying to identify & treat this grassy weed in our lawn that has been spreading aggressively this year. It spreads by seeds from the previous year. See product labels for more information on turfgrass species tolerance and rates, especially where bentgrass or fine fescue species are desired. An inadequate herbicide rate is a common cause of pre-emergence failure. Crabgrass blades can grow up to 5 inches. Goosegrass is especially competitive in soils commonly compacted by foot or equipment traffic and where turfgrass cover is poor. Fine fescue is limited to 0.5 lb ai/A annually. Fenoxaprop-ethyl can provide better goosegrass control than quinclorac. Apply Tenacity at 5 oz/A in perennial ryegrass or fine fescue and 8 oz/A in Kentucky bluegrass or tall fescue. Goosegrass sheaths are compressed, flattened and white near the base, but are also sparsely haired along the edges. Programs that include oxadiazon in combination with dithiopyr, prodiamine, or pendimethalin can provide crabgrass and goosegrass control. These resistant plants will set seed and become the dominant population over time. Pre-emergence herbicides that are commonly used to treat crabgrass and goosegrass are pendimethalin, prodiamine and dithiopyr. I live in the DFW area (8a) and have bermuda grass. Up to 1.5 lb ai/A can be applied annually in Kentucky bluegrass and perennial ryegrass. Multiple applications on 2- to 3-week intervals will be required to provide goosegrass and crabgrass control at < 5.0 fl oz/A. Terms of User and Privacy Policy These weeds are annuals, meaning they germinate from seed when soil temperatures reach a threshold level. Immature goosegrass plants can be removed mechanically, but as plants mature and the central taproot develops, it becomes more difficult to remove the growing point. Especially in areas with a history of moderate to severe infestations, pre-emergence herbicides are more economical and effective than post-emergence herbicides. Smooth crabgrass (left) and goosegrass (right). Do Not Sell My Personal Information, ©2020 Total Landscape Care If you are a non-professional turfgrass manager see FS1308, Crabgrass Control in Lawns for Homeowners in the Northern US. Pin Share Email Maudib / Getty Images . Goosegrass forms leafy tufts which look like they are reclining. Asked April 21, 2017, 4:18 PM EDT. Crabgrass seedheads appear finger-like with spikes (racemes) arising from different points at the top of the stem (Figure 3). Traffic management combined with proper fertilization will increase the competitiveness of desirable turfgrass relative to goosegrass. Herbicides adsorbed to the soil are slowly released into the soil solution over several weeks. Other leaves will continue to emerge until the 4- or 5-leaf stage, at which time the plant begins to tiller. Dallisgrass Crabgrass; Dallisgrass is a more tenacious weed than crabgrass because it can grow back from the root system each year. Plants that germinate in mid-summer after pre-emergence herbicides breakdown will mature much more rapidly due to warmer temperatures. The seedhead (inflorescence) typically contains two to five racemes with seeds arranged in a herringbone pattern. Crabgrass vs quackgrass: Crabgrass is a warm season perennial grass while quackgrass is a cool-season perennial grass. with Rutgers websites to: accessibility@rutgers.edu or complete the Report Accessibility Barrier or Provide Feedback Form. identifying a grassy weed (poa annua vs crab grass?) Both of these are liquid products and Miller points out that there are not really any granular products to treat these weeds post-emergently at this time. In areas with a history of moderate to severe goosegrass or crabgrass infestations, it is more economical and effective to rely primarily on pre-emergence herbicides and use post-emergence herbicides where plants "escape" the pre-emergence herbicide. Notice the hairs along the stem and leaves of large crabgrass, while the smooth crabgrass has a purple stem and is hairless. A single application at 0.5 lb ai/A or sequential applications at 0.25 lb ai/A will often provide season-long crabgrass control in New Jersey. Smooth and large crabgrass (Digitaria ischaemum and D. sanguinalis, respectively) are the most common crabgrass species found in the northeastern United States (Figure 2). The initial application is made at the standard crabgrass pre-emergence timing and the second application occurs 6 to 8 weeks later. Find answers to what is goosegrass and learn how to control it in order to grow a healthier lawn. Goosegrass is a warm season summer annual grassy weed that predominates in exposed, trafficked conditions. Immature leaf-stage plants are much easier to control than tiller-stage plants. Pre-emergence herbicides should be applied to well-established, mature turfgrass. Quinclorac does not control goosegrass but provides excellent control of some broadleaf weeds such as white clover (Trifolium repens). Using one or both herbicides in several consecutive years can select for goosegrass plants that are resistant to these herbicides. Crabgrass Vs. Bermuda Grass. A severe goosegrass infestation may indicate the … On the other hand, granules are more expensive, but require only bags of a product and a spreader. The first step in effectively controlling weeds is knowing what kind of weeds they are. Above the 7-tiller stage most annual grassy weeds are very tough to control and the exact number of tillers present has no practical implications. In New Jersey, the recommended single application rate for crabgrass control is 3.0 lb ai/A or sequential applications at 1.5 lb ai/A. It is important to include methylated seed oil (MSO) or crop oil concentrate (COC) in the tank with Pylex. Updated 09/17/20. Anderson’s Goosegrass and Crabgrass Preventer (oxadiazon + bensulide) is labeled for use on golf course putting greens. Dithiopyr, prodiamine, and pendimethalin are equally effective for crabgrass control at the rates discussed below; goosegrass control varies by product. Written by. Goosegrass can be identified by the whitish stems at the base that are extremely compressed (flattened). Research shows that mowing at the highest height recommended for your particular turfgrass species can significantly reduce crabgrass infestations compared to a low mowing height. Immediate irrigation or rainfall after application is not usually necessary (unless weed seed germination is imminent) but is typically recommended within 2 to 7 days after application. Point of Collection Notice Light and frequent irrigation throughout the growing season is not desirable as it keeps the soil surface moist and encourages weed seedlings to survive and grow. A dense stand of turfgrass is an effective way to prevent crabgrass and goosegrass. I have a guess about what it is but wanted to get your opinion. A sequential application strategy provides better crabgrass control than a single application if the program is initiated several weeks before expected crabgrass emergence and is especially effective on sandy soils with low organic matter. It simply out-competes the cool-season turfgrass in warm conditions. Tank-mix with non-ionic surfactant (0.25% v/v). Granular and liquid formulations are both effective if applied uniformly at the proper rate. This includes mowing at the highest recommended height (typically 3 to 5 inches) for the turfgrass species in the lawn, as well as the proper fertilization, irrigation, and seeding discussed earlier in this publication. Timing with this type of herbicide is much more flexible than that for pre-emergents. As crabgrass matures it can also root at nodes on stems growing along the ground, but these are easily removed as well. “Others use the indicator of when certain plants bloom and assume soil temps are at an approximate level. With the exception of mesotrione, do not apply any of the pre-emergence herbicides listed below if you plan to seed within several weeks after the application, as these herbicides will kill turfgrass seedlings. If an irrigation system is available, irrigate deep and infrequently and only when the desirable turfgrass exhibits signs of low moisture. The best approach to preventing an infestation of these problematic weeds is with an application of a pre-emergent product like The Andersons Goosegrass/Crabgrass Control. If compacted soil is limiting the growth of desirable turfgrass, do not hesitate to aerify even if you have applied a pre-emergence herbicide. Crabgrass species (Digitaria spp.) Soil microbial activity increases with soil temperature, which accelerates herbicide breakdown and reduces the length of weed control. Crabgrass typically germinates mid- to late April in central and northern New Jersey and early to mid-April in southern parts of the state. The seeds are attached closely to the spike and generally germinate two to three weeks after Crabgrass lawn weeds. Figure 4. See Table 3 for more information. Crabgrass (Digitaria spp.) Products discussed are registered for use in cool-season turfgrass and will provide control of crabgrass and/or goosegrass when used according to the label instruction. The grass seeds readily and spreads on the wind from lawn to lawn. They can be especially problematic in low cut turf areas such as putting greens and collar approaches. A pre-emergence herbicide targets the weed as it is germinating, which means you’ll treat before you actually see the weeds. Since seeds can germinate through the summer months, hand removal several times during this period may be necessary. Effective pre-emergence herbicides are listed below (Table 1). Goosegrass is commonly found in highly trafficked areas with compacted soil and poor turfgrass cover. Goosegrass germinates about two weeks later than smooth crabgrass. For more information on turfgrass fertilization and seeding, see FS108, Renovating Your Lawn and E327, Best Management Practices for Nutrient Management of Turf in New Jersey. Rotating herbicide mode of action or using multiple modes of action within the same year can delay the onset of herbicide resistance. When forsythia is in full bloom, crabgrass pre-emergent herbicides should be applied as soon as possible. For example, on a site with a history of moderate to severe infestations, a strong pre-emergence herbicide program is important. In New Jersey, recommended herbicide rates for single applications include dithiopyr at 0.38 to 0.5 lb active ingredient (ai) per acre (A), prodiamine at 0.75 to 1.0 lb ai/A, and pendimethalin at 3.0 lb ai/A. After irrigation, these herbicides are adsorbed to organic matter in the surface ¼- to ½-inch of soil and are slowly degraded over several weeks by soil microbes and rendered ineffective. For goosegrass control, split applications and higher rates are necessary and have provided moderate to good goosegrass control in our research. School of Environmental and Biological Sciences, New Jersey Agricultural Experiment Station, Office of Continuing Professional Education, Commercial Turfgrass and Landscape Maintenance Publications, FS1308, Crabgrass Control in Lawns for Homeowners in the Northern US, E327, Best Management Practices for Nutrient Management of Turf in New Jersey, Report Accessibility Barrier or Provide Feedback Form, Rutgers, The State University of New Jersey, Executive Dean of Agriculture and Natural Resources. Fine fescues and creeping bentgrass are moderately tolerant. Your best bet is to check online for soil temperatures in your area, or monitor them yourself with a soil thermometer, he says. Archived. Organic herbicides are not as effective or consistent as synthetic herbicides. Cooperating Agencies: Rutgers, The State University of New Jersey, U.S. Department of Agriculture, and County Boards of Chosen Freeholders. This publication is intended for professionals who manage lawns, golf courses, athletic fields, and other turfgrass areas with cool-season turfgrass species. Mesotrione will most effectively control crabgrass plants at the 3-tiller stage and smaller. Goosegrass (Galium aparine) is an annual weed found in warm season turf grasses. You can control crabgrass and goosegrass pre-emergently or post-emergently. Liquid products are usually less expensive; however, some lawn care companies don’t like spraying because it involves water, mixing and a larger vehicle with a tank. and goosegrass (Eleusine indica) behave as true annuals in the northeastern United States (Figure 1). If goosegrass and crabgrass are under drought stress, herbicides will be less effective and may injure the desirable turfgrass. Particularly in summers with above-average rainfall, pre-emergence herbicides break down more rapidly and pre-emergence herbicide failure is more common. In areas with a history of infestations that cannot be managed with cultural practices and mechanical removal alone, herbicides are an effective and economical option when applied at the proper time and rate. Individuals with disabilities are Scouting problem areas to find these weeds before plants produce too many tillers will reduce the number of herbicide applications required for control and make hand weeding easier. Supply adequate nitrogen fertility to maintain a dense canopy of desirable turfgrass by applying nitrogen fertilizer in early autumn and, if needed, in spring when cool-season grasses are more competitive than these warm-season weeds. Goosegrass can be identified via its finger-like seed head. You can choose from liquid or granular formulations. Adding a surfactant to Acclaim Extra can improve control. Despite regional differences in climates, you can find them throughout the United States. Quinclorac will generally provide acceptable crabgrass control at the 1-tiller growth stage; control can be inconsistent when applied at the 2- to 4-tiller growth stage. Terms of User and Privacy Policy Dithiopyr provides post-emergence control of leaf-stage (pre-tiller) crabgrass, which is unique among pre-emergence herbicides. species where lower herbicide rates must be used. Multiple applications will be required to control tiller-stage goosegrass. Another difference between the two grass species is that crabgrass has hair on the upper leaf surface and goosegrass does not. It competes very successfully with warm-season and cool-season turfgrasses during summer months. View the product label for Andersons Golf Products Goosegrass / Crabgrass Control from The Andersons, Inc.. See active ingredients, product application, restrictions, and more. As crabgrass or goosegrass mature from the leaf to tiller stage, the application rate of fenoxaprop increases rapidly. Job Opportunities | Webmaster. See the label for more information on application rates to various species. Goosegrass produces seedheads from July to September in Indiana. Quackgrass vs Crabgrass. And like most weeds, they are opportunistic and gain a foothold in turf when turf is stressed. Mesotrione will also provide pre-emergence broadleaf weed control and yellow nutsedge (, Similar to mesotrione, siduron has less residual efficacy than other pre-emergence herbicides but can be safely applied when seeding many cool-season turfgrass species including creeping bentgrass (, Bensulide is less effective against crabgrass and goosegrass than dithiopyr, prodiamine, pendimethalin, and oxadiazon but can be safely applied to golf course putting greens and colonial bentgrass (, Acetyl CoA carboxylase (ACCase) inhibitor (WSSA Group 1), All major cool-season turfgrass species and zoysiagrass (.
