False kyllinga is a weed that has come up from the south. For more information, visit www.eddmaps.org. This herbicide is relatively new to the turfgrass market. False-green kyllinga fruit development is photoperiod-dependent, beginning in late August and continuing until the first frost. A close relative of yellow nutsedge, it prefers wetter soils with poor drainage as well as areas that receive frequent irrigation. Adequate weed control and safety (no injury) on the desirable turfgrass depends on the herbicide being applied to healthy, actively growing weeds and mature, actively-growing turfgrass at the rate indicated on the product label. Thus, invasion of kyllinga is likely to be more severe on over-irrigated properties. Green kyllinga (Kyllinga brevifolia) and false green kyllinga (Kyllinga gracillima) are very similar in appearance, and both are referred to as green kyllinga. Both species are native to Asia and are spreading rapidly in turfgrasses in the southern United States. Photo and data courtesy of Rutgers University, 2018. Currently both of our yards are being devoured by wire grass (perhaps Bermuda grass?) Yellow nutsedge is typically interspersed within the turfgrass canopy while false-green kyllinga tends to form a dense mat (Figure 6). false green kyllinga Kyllinga gracillima Miq. States Counties Points List Species Info. New Jersey. The light green areas are kyllinga. 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. False-green kyllanga injury was assessed 3, 9, 16, 23, and 30 days af-ter treatment (DAT) (Table 2). The introduction of a new sulfonylurea herbicide, tri-floxysulfuron, has the potential to provide excellent con-trol of green and false-green … Herbicide applications should be made shortly after kyllinga shoots have fully emerged in the spring. False green kyllinga is a perennial sedge species with well-developed rhizomes (underground lateral spreading stems). Rotating herbicidal modes of action is important to prevent populations of herbicide-resistant nutsedge from developing. I believe it to be False Green Kyllinga as it has the small round seed balls. 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. Increasing green kyllinga populations correlated with increasing soil sodium; however, sodium did not reach a level believed to be detrimental to turfgrass growth. These leaves typically taper to a sharp point. Always consult the product label for information about the proper conditions for application. Maps. Maryland. This is a warm season weed. False-green kyllinga is an aromatic rhizomatous mat-forming perennial, which may tolerate golf course putting green mowing height.

False green kyllinga is well-adapted to a wide range of mowing heights, often thriving in stands of grass mowed lower than ¼ inch. A close relative of yellow nutsedge, it prefers wetter soils with poor drainage as well as areas that receive frequent irrigation. from yellow or purple nutsedge is to allow the plant to produce a seedhead. green and false-green kyllinga. and false green kyl- Sedges (Cyperus spp.) (Kyllinga brevifolia Rottb.) State List - This map identifies those states that list this species on their invasive … Individuals with disabilities are However, many products registered for yellow nutsedge control will only suppress false-green kyllinga. It is almost identical to green kyllinga, but green kyllinga is only found in the southern United States.It forms a mat of grass and is light green in color, making it obvious in an otherwise dark green patch of turf. 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. The first application is typically made in late May to mid-June. Kyllinga infestations can also spread across larger distances by seed. A close-up of false-green kyllinga seedheads. While this herbicide has systemic properties, multiple applications will be required for long-term kyllinga 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. Trifloxysulfuron controls green and false-green kyllinga more effectively than halosulfuron. There are 2 types of kyllinga – green and false kyllinga. All rights reserved.

Compared to turfgrass species, Kyllinga sp. Figure 1 shows a significant infestation in a New Jersey athletic field. Cockscomb kyllinga is an annual and spreads by seeds. There are 2 types of kyllinga – green and false kyllinga. False-green kyllinga is related to yellow nutsedge (Cyperus esculentus), and both species have a triangular stem. (Click image to enlarge.) Both are perennial species with well-developed rhizomes. Sulfentrazone controlled false-green kyllinga <40% at 12 WAIT. sedge (Cyperus compressus L.), green kyllinga (Kyllinga brevifolia Rottb.) False Green Kyllinga. Refer to the label for restrictions to newly-seeded areas. Unmanaged, false green kyllinga will go dormant after the first frost, and will return and expand each growing season. False Green Kyllinga. Re-establishment of desirable grass species is likely required. Cross-section of triangular stem (left) and three-ranked leaf arrangement (right) of sedge and kyl-linga species. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. No differences were observed between the two kyllinga spp. False-green kyllinga (Kyllinga gracillima) has become increasingly problematic in the Mid-Atlantic and Northeast regions over the past several years. Three-ranked leaf arrangement characteristic of nutsedge and kyllinga species. Green kyllinga can persist under low mowing heights, and unlike yellow and purple nutsedge, these plants produce flowers even under regular mowing. 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. Dismiss can be applied at up to 4 fl. Treatment. false-green kyllinga flowers only during late summer. Green kyllinga and false green kyllinga are very similar in appearance, and both are referred to as green kyllinga. 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.)

It also occurs in Hawaii. This is a warm season weed. This herbicide should be applied with a suitable surfactant as indicated by the label. 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. Kyllingas tend to have a finer leaf texture and are shorter growing than other … False-green kyllinga rhizomes are typically closer to the soil surface than those of bermudagrass, so removal is more practical. 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. 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. False-green kyllinga tends to thrive at mowing heights common in turfgrass areas all the way from putting greens to lawns. However, this strategy is expensive and can result in the area being unavailable during the renovation. Yellow nutsedge interspersed within turfgrass. Thus, because of the difficulty in distinguishing these two species mor-phologically, perceived variability in herbicidal control could be the result of misidentification. Currently both of our yards are being devoured by wire grass (perhaps Bermuda grass?) Include a non-ionic surfactant as directed by the label; Sedgehammer+ contains a non-ionic surfactant. It grows prolifically in poorly drained areas or areas that are frequently wet. Cross-section of triangular stem (left) and three-ranked leaf arrangement (right) of sedge and kyl-linga species. Both species are native to Asia and are spreading rapidly in turfgrasses in the southern United States. Figure 1: A severe false-green kyllinga infestation in an athletic field. Post-emergent herbicide applications should be made in the late spring or early summer before the plant has time to establish or expand its network of rhizomes. It is important to make sure that you cut or fraze deep enough to remove the rhizomes. Mode of Action: ALS inhibitor Flowering stalks of the kyllinga are triangular in cross-section and end in a globular, dense flower head consisting of green flowers. Green and false green kyllinga are found on greens, tees, fairways and rough. Further research is needed to assess the potential … Long-term weed control is possible only if the underlying cause of the weed's competitive advantage is resolved. These weeds thrive under mowing and are prolific in areas that are poorly drained or frequently wet.

About This Subject; View Images Details; View Images; Selected Images. often look pale green and grow in tufts, or bunches. False-green kyllinga flowers from late August un-til frost, whereas green kyllinga flowers throughout the summer until frost. 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. Trade Name: Celero (8–14 oz./A). I believe it to be False Green Kyllinga as it has the small round seed balls. Green kyllinga appeared to be more difficult to control than false-green kyllinga. Do not seed before 4 weeks after an application. Apply with a non-ionic surfactant at 0.25% v/v. Kyllinga, it may not be a weed you’re familiar with yet, but the quicker you’re able to recognize and control this invasive sedge the better. Top of page.

At 12 WAIT, imazosulfuron generally controlled false-green kyllinga more effectively than other treatments at all locations. Note that SedgeHammer is reported as more effective against false green kyllinga than green kyllinga. Habitat Nutsedge and kyllinga species thrives in moist, poorly-drained soils. 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. When kyllinga is in bloom, look for a somewhat round, green seedhead above three leaves (Figure 8). Prodiamine does not provide pre-emergence kyllinga control, but will provide pre-emergence grass control. Cockscomb kyllinga is an annual and spreads by seeds. This plant has no children Legal Status. It is by Charles T. Bryson at USDA Agricultural Research Service. It does show some characteristics of behaving as a short-lived perennial under certain conditions. False-green kyllinga control and cover were evaluated weekly from 4 to 12 weeks after treatment (WAT) (Tables 3, 5). thin-leaved flatsedge. The best management approach is to prevent new infestations by excluding and monitoring for the weed. These weeds thrive under mowing and are prolific in areas that are poorly drained or frequently wet. Pre-emergent herbicides are not an effective means of control. Results may not be evident for up to 3 weeks after application. and false green kyllinga (Kyllinga gracillima Miq.). False Green Kyllinga Trial. Echelon is a combination of the pre-emergence herbicide prodiamine and sulfentrazone. 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. Sulfentrazone can be applied to most cool-season turfgrasses and is a resistance management alternative to ALS-inhibiting herbicides. The seed head is pale green in color initially, often turning brown at maturity. The presence of false green kyllinga can indicate a need to adjust irrigation output and/or improve drainage to alleviate perpetually saturated soil. and kyllingas (Kyllinga linga (Kyllinga gracillima Miq.). Green kyllinga (Kyllinga brevifolia) and false green kyllinga (Kyllinga gracillima) are very similar in appearance, and both are referred to as green kyllinga. Forming from reddish-purple rhizomes, this lawn weed has dark green leaves and stems. New Jersey Agricultural Experiment Station It does show some characteristics of behaving as a short-lived perennial under certain conditions. It is important to make sure that you cut deep enough to remove the rhizomes. either green- or false-green kyllinga. Rutgers Cooperative Extension, a unit of the Rutgers New Jersey Agricultural Experiment Station, is an equal opportunity program provider and employer. 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). 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). false green kyllinga Kyllinga gracillima Miq. 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. Green kyllinga was seemingly more difficult to control than false-green kyllinga. Be sure to plan herbicide programs well in advance of seeding to make sure they will not reduce seedling establishment. They are able to thrive and reproduce at mowing heights ranging from 0.5 in to 3 in. False-green kyllinga is a perennial sedge that is prevalent in warm-season turf but has also become an issue in cool-season turfgrass. Sequential applications of imazosulfuron controlled false-green kyllinga 100% at 12 WAIT. 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. – low spikesedge Subordinate Taxa.
