Green kyllinga has narrow grasslike leaves and when left unmowed they can reach up to 15 inches in length. Ideal conditions for the growth of this weed would be lawn areas that receive a lot of sunlight and are poorly drained and/or over irrigated. Green kyllinga appeared to be more difficult to control than false-green kyllinga. and false green kyl-linga (Kyllinga gracillima Miq.). Green kyllinga and false green kyllinga are very similar in appearance, and both are referred to as green kyllinga. False-green kyllinga does not contain underground tubers like yellow nutsedge so physical removal using a sod cutter or fraze mowing is an effective option. and false green kyl- Sedges (Cyperus spp.) False Green Kyllinga Trial. However, many products registered for yellow nutsedge control will only suppress false-green kyllinga. … It is a warm-season perennial weed that emerges in late spring/early summer when soil temperatures increase, and it grows rapidly throughout the summer months before going dormant after the first frost in the fall (Figures 2 and 3). Kyllinga, False Green (Kyllinga gracilima) Kyllinga, fragrant (Kyllinga sesquiflorus) Kyllinga, Green (Kyllinga brevifolia) Mustard, Wild (Brassica kaber (Sinapis arvensis)) Nutsedge, Purple (Cyperus rotundus) Nutsedge, Yellow (Cyperus esculentus) Pennycress, Field (Thlaspi arvense) Here are a few more weeds mentioned on their label. States Counties Points List Species Info. Trifloxysulfuron controls green and false-green kyllinga more effectively than halosulfuron. The best management approach is to prevent new infestations by excluding and monitoring for the weed. Both are perennial species with well-developed rhizomes. Green kyllinga (Kyllinga brevifolia) and false green kyllinga (Kyllinga gracillima) are very similar in appearance, and both are referred to as green kyllinga. Although it is only labeled for control of annual kyllinga and nutsedge species, Rutgers research trials demonstrated excellent efficacy against false-green kyllinga at the low and high label rate. Cockscomb kyllinga is found in fairways and rough. Herbicide applications should be made shortly after kyllinga shoots have fully emerged in the spring. It grows prolifically in poorly drained areas or areas that are frequently wet. When a single stem is viewed from the above these species have three leaves spaced at 120° angles. False-green kyllinga (Kyllinga gracillima) has become increasingly problematic in the Mid-Atlantic and Northeast regions over the past several years. False green kyllinga is a perennial sedge species with well-developed rhizomes (underground lateral spreading stems). – low spikesedge Subordinate Taxa. For more information, visit www.eddmaps.org.

Figure 5. Compared to turfgrass species, Kyllinga sp. Nutsedge or kyllingas treated with sulfentrazone will typically display injury symptoms within 48 hours after application. False kyllinga is a weed that has come up from the south. Green kyllinga was seemingly more difficult to control than false-green kyllinga. The introduction of a new sulfonylurea herbicide, tri-floxysulfuron, has the potential to provide excellent con-trol of green and false-green … Averaged over herbicide and placement level, false-green kyllinga shoot number 30 d after treatment (DAT) and rhizome weight 60 DAT were reduced more than those of green kyllinga. oz./A, control was improved. False Green Kyllinga Trial. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. Individuals with disabilities are A difficult-to-control perennial sedge, false green kyllinga (Kyllinga gracillima) spreads via rhizomes below the soil surface to form a dense mat that can choke out stands of desirable turf species. Means followed by the same letter are not sigificantly different according to Fisher ’s Protected LSD test (p ≤ 0.05) 2 DAT = days after treatment 3 Sedgehammer and Celero applied with non-ionic surfactant (Activator 90) at 0.25% v/v. and kyllingas (Kyllinga linga (Kyllinga gracillima Miq.). False-green kyllinga flowers from late August un-til frost, whereas green kyllinga flowers throughout the summer until frost. Kyllinga is relatively low growing so it thrives under mowing. Yellow and purple nutsedge will produce a cluster of spikes as a seedhead. Sequential applications of bentazone and MSMA, single applications of halosulfuron, sulfentrazone applied at 0.42 and 0.56 kg/ha, and single and sequential applications of trifloxysulfuron controlled false-green kyllinga by at least 10% greater than green kyllinga at 1 YAIT. Yellow nutsedge is typically interspersed within the turfgrass canopy while false-green kyllinga tends to form a dense mat (Figure 6). oz./A); Echelon (8–24 fl.

Green kyllinga (Kyllinga brevifolia) and false green kyllinga (Kyllinga gracillima) are very similar in appearance, and both are referred to as green kyllinga. It also occurs in Hawaii. Origin: Native to the United States and Latin America, and found in the U.S. from Arkansas east to Georgia and north to New York. These weeds thrive under mowing and are prolific in areas that are poorly drained or frequently wet. Vexis is labeled for use on: Warm-Season Turfgrasses: Bermudagrass (common or hybrid) Bahiagrass; Buffalograss; Centipedegrass; Kikuyugrass; Seashore paspalum; St. Augustinegrass (including improved varieties, such as floratam and bitterblue) Zoysiagrass; Cool-Season Turfgrasses: … Field experiments were conducted to evaluate oz./A) Note: Many products contain sulfentrazone in combination with other herbicides but often at rates too low for kyllinga or yellow nutsedge suppression. Both species are native to Asia and are spreading rapidly in turfgrasses in the southern United States. green and false-green kyllinga. Halosulfuron applied sequentially, imazaquin with and without MSMA, and trifloxysulfuron applied singly or sequentially controlled green and false-green kyllinga by 89-99% at 10 weeks after initial treatment. False Green Kyllinga. The dense mat continues to expand as the underground stems (rhizomes) spread outwards ultimately displacing the desired turfgrass. False-green kyllanga injury was assessed 3, 9, 16, 23, and 30 days af-ter treatment (DAT) (Table 2). Figure 6. Further research is needed to assess the potential … About This Subject; View Images Details; View Images; Selected Images. Newly-seeded turfgrass should have received at least two mowings prior to application. Sequential applications of halosulfuron-methyl or single applications of imazosulfuron have provided greater kyllinga control than sequential applications of sulfentrazone at 4 and 6 fl. ISSN : 0890-037X. The seed head is pale green in color initially, often turning brown at maturity. Results may not be evident for up to 3 weeks after application. A close-up of false-green kyllinga seedheads. The major morphological difference between the two species is the presence of denticulate appendages on the lemma of green kyllinga seed, where-as these appendages are absent in false-green kyllinga with Rutgers websites to: accessibility@rutgers.edu or complete the Report Accessibility Barrier or Provide Feedback Form. There are several herbicides that can provide effective kyllinga control when applied according to the label. Apply with a non-ionic surfactant at 0.25% v/v. Cockscomb kyllinga is found in fairways and rough. A single application of imazosulfuron at the low or high rate provided the same amount of control as two applications of halosulfuron-methyl at the high label rate. Habitat Nutsedge and kyllinga species thrives in moist, poorly-drained soils. Sulfentrazone controlled false-green kyllinga <40% at 12 WAIT. Therefore, it is very important to understand that control is achieved with MULTIPLE applications of Dismiss or SedgeHammer. Mode of Action: Protoporphyrinogen oxidase (PPO) inhibitor False-green kyllinga is an aromatic rhizomatous mat-forming perennial, which may tolerate golf course putting green mowing height. They are able to thrive and reproduce at mowing heights ranging from 0.5 in to 3 in. – low spikesedge Subordinate Taxa. Green kyllinga and false green kyllinga are very similar in appearance, and both are referred to as green kyllinga. Echelon is a combination of the pre-emergence herbicide prodiamine and sulfentrazone. Both are perennial species with well-developed rhizomes. belong to the sedge family (Cyperaceae) and are typically larger and more interspersed inat first glance can look like grasses, especially in turfgrass than kyllinga plants and are commonlymowed turf. Control Options Selective Control Herbicides from multiple families provide selective control of sedges and kyllingas in turfgrass (Table 1). of Dismiss per acre in Rutgers research trials. Prodiamine does not provide pre-emergence kyllinga control, but will provide pre-emergence grass control. Habitat. False-green kyllinga fruit development is photoperiod-dependent, beginning in late August and continuing until the first frost. Trade Names: Sedgehammer (0.66–1.33 oz./A), Sedgehammer+, ProSedge 2, Manage (no longer sold), others. Dismiss can be applied at up to 4 fl. For more information, visit www.eddmaps.org. Do not apply to golf course putting greens. oz./A of Dismiss per year. In the past 5 years kyllinga has recently surfaced as a major problem for lawns across New Jersey. Thus, invasion of kyllinga is likely to be more severe on over-irrigated properties. Kyllinga may be indicative of chronically excessive soil wetness, which should always be addressed as part of an overall treatment program. Vexis® Herbicide Granular* uses the proprietary new active ingredient pyrimisulfan to deliver exceptional control of sedge and kyllinga species, plus listed broadleaf weeds. Currently both of our yards are being devoured by wire grass (perhaps Bermuda grass?) A dense mat of false-green kyllinga with seedheads. Of the two predominant sedge species in Tennessee, yellow nutsedge is more easily controlled than purple nutsedge. Pre-emergent herbicides are not an effective means of control. It has been reported as far north as Connecticut and south to the Carolinas. Figure 2. Mode of Action: ALS inhibitor False-green kyllinga (Kyllinga gracillima) has become increasingly problematic in the Mid-Atlantic and Northeast regions over the past several years. Most grass species have leaves on opposite sides of the stem at 180° angles. I believe it to be False Green Kyllinga as it has the small round seed balls. At 12 WAIT, imazosulfuron generally controlled false-green kyllinga more effectively than other treatments at all locations. It is by Charles T. Bryson at USDA Agricultural Research Service. Kyllinga is relatively low growing so it thrives under mowing. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. Trade Name: Celero (8–14 oz./A). Rutgers, The State University of New Jersey False-green kyllinga is in the same plant family (sedges or Cyperaceae) as yellow nutsedge (Cyperus esculentus); both species have a triangular stem and three-ranked leaf arrangement (Figures 4 and 5). Probably the easiest way to distinguish Kyllinga sp. Include a non-ionic surfactant as directed by the label; Sedgehammer+ contains a non-ionic surfactant. Future research will evaluate herbicide programs in combination with seeding. Always consult the product label for information about the proper conditions for application. However, the most common species found in turfgrasses include yellow nutsedge (Cyperus esculentus L.), purple nutsedge (Cyperus rotundus L.), annual sedge (Cyperus compressus L.), green kyllinga (Kyllinga brevifolia Rottb.) The light green areas are kyllinga. Refer to the label for restrictions to newly-seeded areas. There are 2 types of kyllinga – green and false kyllinga. False-green kyllinga is also very similar to green kyllinga (Kyllinga brevifolia), but green kyllinga is typically found in the southern and western U.S. False-green kyllinga is the only species reported in northern regions of the U.S., which is probably due to greater cold tolerance than green kyllinga. Figure 4. Herbicides for control of sedges and kyllingas are only effective when applied to actively growing plants, so applications should be made from May through August. It does show some characteristics of behaving as a short-lived perennial under certain conditions. Currently both of our yards are being devoured by wire grass (perhaps Bermuda grass?) either green- or false-green kyllinga. Much like nutsedge, kyllinga is often found in areas with excessive soil wetness, which likely increases its competitive advantage over desirable turfgrass. It does show some characteristics of behaving as a short-lived perennial under certain conditions. Like most weeds, dense, healthy turf is the first step in effective control of false green kyllinga. Make follow-up applications after re-growth is observed and sufficient shoot tissue is present for herbicide absorption. False-green kyllinga seedhead production is influenced by day-length. Note that SedgeHammer is reported as more effective against false green kyllinga than green kyllinga. When Dismiss was applied at 8 fl. This species is Native to certain parts of the United States but may be invasive to others. This dense mat makes it appear similar to turfgrass in the summertime, but it usually has a lighter green color (Figure 7). False-green kyllinga (Kyllinga gracillima) is a warm-season perennial sedge (Cyperaceae) species that has become increasingly problematic in cool-season turfgrass. Figure 1. (Kyllinga brevifolia Rottb.) thin-leaved flatsedge. False green kyllinga (Kyllinga gracillima) is well-adapted to a wide range of mowing heights, often thriving in stands mowed lower than ¼ inch. Mention or display of a trademark, proprietary product, or firm in text or figures does not constitute an endorsement by Rutgers Cooperative Extension and does not imply approval to the exclusion of other suitable products or firms. Figure 1 shows a significant infestation in a New Jersey athletic field. Rotating herbicidal modes of action is important to prevent populations of herbicide-resistant nutsedge from developing. Re-establishment of desirable grass species is likely required. State List - This map identifies those states that list this species on their invasive … regarding false-green kyllinga control or comparing the two species' responses to herbicides. Sulfentrazone can be applied to most cool-season turfgrasses and is a resistance management alternative to ALS-inhibiting herbicides. While herbicide resistance to kyllinga and sedge species is not thought to be widespread, there are reports of sedge species resistant to the class of herbicides known as ALS-inhibitors in turfgrass. A close relative of yellow nutsedge, it prefers wetter soils with poor drainage as well as areas that receive frequent irrigation. oz./A on creeping bentgrass; do not apply to putting greens or tees. A difficult-to-control perennial sedge, false green kyllinga (Kyllinga gracillima) spreads via rhizomes below the soil surface to form a dense mat that can choke out stands of desirable turf species. Figure 1 shows a significant infestation in a New Jersey athletic field. Kyllinga seeds are flat, oval and can reach about 3mm long. Forming from reddish-purple rhizomes, this lawn weed has dark green leaves and stems. I believe it to be False Green Kyllinga as it has the small round seed balls. New Jersey. Relying on herbicides with the same mode of action for several consecutive years can accelerate the development of herbicide-resistant weeds. (Click image to enlarge.) Image 2100021 is of false green kyllinga (Cyperus brevifolioides ) flower(s). Image 2100021 is of false green kyllinga (Cyperus brevifolioides ) flower(s). and I am curious if this could out grow the wire grass and maybe be a way to get rid of it and maybe then we could remove our "savior" and go back to real grass. Kyllingas tend to have a finer leaf texture and are shorter growing than other … The weed has one to three dark green, glossy, flat, hairless leaves that on average range from 2-2/5 to 6 inches (6–15 cm) long. Green Kyllinga can be identified as a mat-forming perennial grassy weed. Kyllinga Control Controlling green kyllinga in turfgrass requires a combination of control procedures. false green kyllinga Kyllinga gracillima Miq. Green or false-green kyllinga control was equivalent at fairway and rough mowing heights. Flowering stalks of the kyllinga are triangular in cross-section and end in a globular, dense flower head consisting of green flowers. encouraged to direct suggestions, comments, or complaints concerning any accessibility issues Green kyllinga can persist under low mowing heights, and unlike yellow and purple nutsedge, these plants produce flowers even under regular mowing. It is by Charles T. Bryson at USDA Agricultural Research Service. is misdiagnosed as a nutsedge. False-green kyllinga rhizomes are typically closer to the soil surface than those of bermudagrass or other perennial warm-season grasses, so removal is more practical. Cross-section of triangular stem (left) and three-ranked leaf arrangement (right) of sedge and kyl-linga species. Selected Images. Refer to the label for restrictions to newly-seeded areas. Yellow nutsedge typically is interspersed within the turfgrass canopy, while false-green kyllinga tends to form a dense perennial stoloniferous/rhizomatous mat that appears similar to turfgrass. EDDMapS Distribution - This map is incomplete and is based only on current site and county level reports made by experts, herbaria, and literature. Good spray coverage is important for suppression with sulfentrazone. Although false-green kyllinga does not have tubers like yellow nutsedge, its rhizomes make it extremely difficult to control. Follow-up applications to re-emerging shoots may be required to achieve full control. A difficult-to-control perennial sedge, false green kyllinga spreads via rhizomes below the soil surface to form a dense mat that can choke-out stands of desirable turf species. Its seed head is usually round or oblong in shape and clustered at the head, usually with three short leaves below. and false green kyllinga (Kyllinga gracillima Miq.). A close relative of yellow nutsedge, it prefers wetter soils with poor drainage as well as areas that receive frequent irrigation. They are able to thrive and reproduce at mowing heights ranging from 0.5 in to 3 in. regarding false-green kyllinga control or comparing the two species' responses to herbicides. and kyllingas (Kyllinga linga (Kyllinga gracillima Miq.). Kyllinga pumila Michx. This is a warm season weed. False-green kyllinga is related to yellow nutsedge (Cyperus esculentus), and both species have a triangular stem. Top of page. Reproduction is from seeds and rhizomes. Kyllinga species are becoming a more wide-spread problem weed in highly managed turfgrass. Unmanaged, false green kyllinga will go dormant after the first frost, and will return and expand each growing season. Averaged over herbicide and placement level, false-green kyllinga shoot number … Kyllinga infestations can also spread across larger distances by seed. For additional information on control of kyllinga and nutsedge in cool-season turf, review the article “ Identifying and Understanding False-Green Kyllinga in Cool-Season Turf.” Even if rough has been mowed recently, the rapid growth of nutsedge quickly becomes unsightly and makes it difficult to locate and advance a ball. Sequential applications of imazosulfuron controlled false-green kyllinga 100% at 12 WAIT. Click on a place name to get a complete protected plant list for that location. Figure 8.

The advantage of physical removal is that seeding or sodding can be completed immediately after removal with no herbicide residual concerns. A triangular stem, characteristic of nutsedge and kyllinga species (resting on a pen for scale). Figure 1. For example, two applications of SedgeHammer will suppress green kyllinga and probably not kill it unless it is small. Sequential applications of bentazon and MSMA, single applications of halosulfuron, sulfentrazone applied at 0.42 and 0.56 kg/ha, and single and sequential applications of trifloxysulfuron controlled false-green kyllinga at least 10% greater than green kyllinga at 1 YAIT. Rutgers research trials have demonstrated that it provides good false-green kyllinga control after two applications spaced 4 weeks apart. Yellow nutsedge interspersed within turfgrass. New Jersey Agricultural Experiment Station A close relative of yellow nutsedge, it prefers wetter soils with poor drainage as well as areas that receive frequent irrigation. Cooperating Agencies: Rutgers, The State University of New Jersey, U.S. Department of Agriculture, and County Boards of Chosen Freeholders. Kyllinga species are becoming a more wide-spread problem weed in highly managed turfgrass. Kyllinga control provided by Dismiss NXT was similar to Dismiss in Rutgers research trials. Maps. Sedge and kyllinga leaves … Nutsedge plants are typically larger and more interspersed in turfgrass than kyllinga plants and are commonly found in plant beds, ditch banks, and low-lying wet areas. However, this strategy is expensive and can result in the area being unavailable during the renovation. Green and false green kyllinga are found on greens, tees, fairways and rough. Figure 3: A patch of dormant false-green kyllinga surrounded by perennial ryegrass in a golf course fairway. Photo and data courtesy of Rutgers University, 2018. Unlike purple nutsedge and false-green kyllinga, yellow nutsedge does not tolerate lower mowing heights. In general, sedges are more easily controlled by these herbicides than either green- or false-green kyllinga. Herbicides used for false-green kyllinga control/suppression will also provide yellow nutsedge control. While this herbicide has systemic properties, multiple applications will be required for long-term kyllinga control. Sequential applications of bentazon and MSMA, single applications of halosulfuron, sulfentrazone applied at 0.42 and 0.56 kg/ha, and single and sequential applications of trifloxysulfuron controlled false-green kyllinga at least 10% greater than green kyllinga at 1 YAIT. Common names are from state and federal lists. This is a warm season weed. often look pale green and grow in tufts, or bunches. Both species are native to Asia and are spreading rapidly in turfgrasses in the southern United States. with regard to absorption, translocation, or metabolism of either … Endangered. Seeding within 4 weeks of an application can inhibit establishment. All rights reserved. All sedges and kyllingas are perennial plants that are troublesome to manage and control in a turfgrass environment. (Click image to enlarge.) Greenhouse studies were conducted to evaluate shoot number, shoot weight, rhizome weight, and root weight reduction of green and false-green kyllinga at three placement levels (soil applied, foliar applied, and soil foliar applied) and five herbicide treatments (CGA-362622, halosulfuron, imazaquin, MSMA, and imazaquin MSMA). This herbicide is relatively new to the turfgrass market. Common names are from state and federal lists. 88 Lipman Drive, New Brunswick, NJ 08901-8525 Due to the underground rhizomes and dense mat that forms, hand removal of kyllinga is difficult. Halosulfuron-methyl was less effective in Indiana than in New Jersey. Seeding desirable turfgrass into infested areas should also be considered. If solitary plants of green kyllinga are found, they should be grubbed out (i.e., remove the entire plant, roots and all) and the area monitored for several months to ensure removal was complete. and false green kyllinga (Kyllinga gracillima Miq.). To treat Green Kyllinga, we recommend an application of Sedgehammer or Sedgehammer+ (Plus) for post-emergent control. Studies were conducted to evaluate the absorption, translocation, and metabolism of ¹⁴C-halosulfuron and ¹⁴C-trifloxysulfuron when foliar applied to green and false-green kyllinga. The presence of false green kyllinga can indicate a need to adjust irrigation output and/or improve drainage to alleviate perpetually saturated soil. Thus, because of the difficulty in distinguishing these two species mor-phologically, perceived variability in herbicidal control could be the result of misidentification. from yellow or purple nutsedge is to allow the plant to produce a seedhead.
