[53], Timing is important when applying herbicides, whether you wish to kill the above-ground growth or tranlocate herbicides to the root system. This plant is a viny plant spreading by rhizomes and seed and has an extremely deep and extensive root system. Stems twine and can grow to 5 ft. (1.5 m) or longer. Stems usually trail along the ground or climb foliage and other structures. At the end of the second year the field bindweed was being controlled under both tillage and non-tillage conditions. [6] Quail may retain the seed for 24 hours, ducks, 5, geese, 19, lesser yellowlegs, 6, green jays, 13, ravens, 8, mocking birds, 2 and starlings 10.[6]. Proceedings of the North Central Weed Control Conference, 33:141-142. Not only do hand sprayers allow more precise application of herbicides, Duncan-Yerkes and Weller (1996)[52] showed that lower spray volumes of glyphosate promoted herbicide absorption through better coverage and increased herbicide/surfactant concentration. Alcock and Dickinson (1974)[15] find the species restricted to areas with available moisture throughout the summer and autumn in Australia. [7] Permeability can be achieved artificially by treatments with concentrated sulphuric acid for 45-60 minutes [38][10], ethyl alcohol for 20 hours [38] or by mechanical scarification. 1963a. [7][5][10] Under laboratory conditions optimal temperatures for germination of field bindweed ranged from 20-35°C, but seeds may also germinate at temperature as low as 10°C and as high as 40°C. In general, species that grow vigorously during the winter and early spring may be the best competitive crops, because they force field bindweed plants to compete for light when it grows later in the season.

American Book Co., New York. Pacific Northwest Weed Control Handbook. [7][10] Estimates of the number of seeds in a pure stand of field bindweed range from 50,000 to 20 million per hectare.[7]. PhD. If the above-ground portion of the weed is continually destroyed, the root eventually starves and dies. Field bindweed (Convolvulus arvensis) Click on images to enlarge . Scientific Name Convolvulus arvensis ← → Other Common Names: creeping jenny. Turner, N.R. Bindweed control in the Panhandle of Texas. They are dull green with readily visible veins. Gigax, D.R. University of California Press, Berkeley. In a 1995 survey, managers for The Nature Conservancy preserves ranked the likelihood of control “medium” to “low.” On two preserves, managers successfully reduced field bindweed populations (Youtie, 1994; Swarz, pers. 1993. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. Williams, M.C., F.W. New York Botanical Garden, Bronx, NY. Most herbicides are not absorbed by dormant seeds and are therefore ineffective at controlling them. Government Printing Office, Washington, D.C. Whitesides, R.E. Plunknett, J.V. Heritability of glyphosate susceptibility among biotypes of field bindweed. Scientific name Scientific name (unprocessed) Kingdom Phylum Class Order Family Genus Species Subspecies Identified to rank Name match metric Lifeform Common name ... 356 results for SPECIES: Convolvulus arvensis placeholder. Youtie (1994) used glyphosate applied from backpack sprayers to control field bindweed, and while her infestations persist, they are not spreading. Peeper. 1946. Wiese, A.F. Most researchers suggest that herbicides be applied to field bindweed when the plant is most vigorous. 1978. & G. Kapusta. Phillips, W.M. 1944. Differences in degrees of control were attributed to rainfall variation. [43] Swan (1980)[5] suggests using straw, paper, wood chips or black plastic and stresses the importance of thorough coverage. Field bindweed suffering drought stress and plants grown from seed (instead of vegetative propagules) are more resistant to glyphosate. The effect of 2,4-D formulations on field bindweed with application of 3 rates and 3 stages of growth at Scotland, ND. Nectar is produced at the base of the tube of fused petals, and attracts various pollinators including Halictid bees, honeybees, bumblebees, butterflies and moths. The taxonomic treatment of polymorphic variation. The control was approximately 76% with quinclorac at 0.5 lb/A plus dicamba at 0.25 lb/A and a crop oil surfactant Sun-It at .25 G. The wheat injury was 22%. Field bindweed. ... Nomenclature and Classification > Taxon Record Name > Scientific Name. Sandberg, C.L., W.F. [76] Attempts to extend its range from eastern North America to the western plains in the 1970s were unsuccessful.[77]. [2] Swarz had success using only one cultivation per season (see “The Nature Conservancy Case Study” below). & W.M. Both ‘bindweed’ and ‘wild morning-glory’ are applied to all the weedy species in the genus [2], but ‘field bindweed’ is used almost exclusively to refer to Convolvulus arvensis L. and is accepted by the Weed Science Society of America as the “official” common name. [2] Like other weeds, field bindweed takes nutrients and water that would otherwise be available to desirable species . They are 0.5-1.2 cm long, and their shapes vary, depending on the number produced in the fruit; they are rounder when only one is produced and progressively thinner as more are produced. Seedlings that germinated in August and September reached a soil depth of 25-50 cm by November, but they were unlikely to overwinter because their root systems were insufficiently established. Frazier, J.C. 1943a. Watsonia 10:385-390. Color, brightness and other floral characteristics attracting insects to the blossoms of some Canadian weeds. Mulching improves the soil because it increases the temperature and moisture and, as a result, nitrification. Texas Agricultural Experimental Station Bulletin, #802. A treatment of picloram at 0.25 lb acid equivalent/A plus 2,4-D at 1 lb acid equivalent/A gave 89-100% control. The Nature Conservancy Weed Report for the northeast Oregon Middle Fork John Day on, This page was last modified 19:42, 8 January 2014 by. The website also provides access to a database and images of plants photos and herbarium specimens found at … [10] [36]Brown and Porter (1942)[10] found that 65% of a carefully selected set of plump 55-year old dry-stored seeds were still germinable, and those buried deeply in the soil can persist nearly as long. Journal of the American Society of Agronomists 31:352-357. Weaver, S.A. & W.R. Riley. Scientific Name: Plant Physiology 20:246-257. In agriculture, control has been most successful where tillage is combined with herbicide application, although herbicide application alone can be effective. King County Department of Natural Resources and Parks Water and Land Resources Division, Oregon Department of Agriculture Plant Programs, Noxious Weed Control, http://wiki.bugwood.org/index.php?title=Convolvulus_arvensis&oldid=50175, Center for Invasive Species and Ecosystem Health at the University of Georgia. Cultivators such as rod weeders or shar duckfoot-types with overlapping sweeps should be used. [58], Repeated use of the same or similar herbicides can result in herbicide resistant strains of field bindweed, which can be difficult to control. Crafts, A.S. & P.B. & Anderson, L.E. 1995. University Press of Hawaii, Honolulu. Effects of watering frequency, drought and glyphosate on growth of field bindweed (, Westwood, J.A. Initially, these lateral roots function as feeding roots for above-ground growth [20] but later aid in vegetative reproduction. European morning glory. Waddington, K.D. Flora of Tamil Nadu, VOL. Leaves are mostly hairless, ovate (egg-shaped with broad end at base)-oblong to lanceolate(lance-like) in shape, up to 7.5 cm long by 3 cm width, with a notched base. Youtie successfully halted the spread of the species through herbicide application while Swarz controlled the weed with tillage and competitive species plantings. The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. Wiese, A.F. For best results, the cultivator should be capable of cutting 15cm below the soil surface. 1992. Schoenhals, S. Amosson. Due to its climbing ability, it is able to infest various levels of a plant community (i.e. U.S. Department of Agriculture Farmer’s Bulletin 368. & M.W. Halictid foraging is highest from 8:30-11:30 a.m.[28] Compared to other weed species found in Canada, field bindweed is intermediate in pollinator visitation.[29]. [43] Small areas of field bindweed may be controlled using paper mulch. Likewise, Callihan et al. Furthermore, early and mid-spring grazing should be avoided Beidleman and Knight (1995) (Phantom Canyon Preserve) were unable to establish native species to compete with field bindweed, while Chris O’Brien (see “The Nature Conservancy Case Study” above) at Thousand Springs Preserve successfully established perennial grasses. [68] Control efficiency may depend greatly on the relative humidity. [2] Sheep have been used in controlling the weed but only eat above ground parts, and only when there is no other vegetation. Canadian Journal of Plant Science 43:230-232. Mature leaves are typically 2-6 cm long. There are two varieties: is the Argus tortoise beetle. If you decide to pull field bindweed it should be done frequently (see below for information on timing of cultivation). 1953. 1996. [62] Investigators have unsuccessfully tried to correlate the morphology of field bindweed strains with their herbicide resistance.[60][63]. 1976. Bindweed: How to control it. Field bindweed has deep roots that store carbohydrates and proteins. [21], September treatments were applied in Lincoln, Nebraska, during a period with little rainfall. Jordan & W.H. The bracts are much smaller than those of hedge bindweed. 1996. Best (1963a)[34] investigated the spread of field bindweed by monitoring 25 shoots growing from transplants under non-competitive conditions. Habit. Smith 1960. Relation of root reserves to control of European bindweed. Convolvulus is derived from the Latin, convolere, meaning to entwine, and arvensis means ‘of fields’. Field bindweed may be confused with Polygonum convolvulus L. and with Calystegia sepium (L.) R. Br..[6][15] Polygonum convolvulus L. (black or corn bindweed) is a hairless annual species with fibrous roots and slender climbing stems. 1974. The effect of 2,4-D on field bindweed. D. VanNostrand Company, Inc., Princeton, NJ. 1950b. Field bindweed (. C. arvensis has deep, spreading roots and rhizomes. The time of year, developmental stage of the plants, and rainfall/soil moisture conditions are all important factors to consider.[54]. Managers are generally pessimistic about field bindweed control and question whether eradication is possible. [35][10] Impermeable seeds must wait at least until the next season to germinate, and they may lie dormant in the soil for many years. The root system and rhizomes are extensive, whitish … Proceedings North Central Weed Science Society, p.74. It has been used in traditional medicine, and extracts from the leaves are sold as dietary supplements. 1991. Before the widespread use of herbicides, farmers sometimes disced their fields as much as twenty times per year, starting as soon as field bindweed leaves appeared. Field bindweed is primarily a problem at this preserve’s riparian corridors and mountain-mahogany shrubland/grassland, where it can rapidly choke out native grasses and forbs. [3] Other common names are ‘possession vine,’ ‘creeping jenny,’ ‘creeping charlie’ [4], ‘field morning-glory,’ ‘orchard morning-glory’ [3], ‘European bindweed’ [5], ‘corn-bind,’ ‘morning-glory’ [6], and ‘small-flowered morning-glory’. Wiese, A.F., B.W. (1990)[6] suggest every 14 days. The petiole is flattened, and grooved on the upper side. [25] Bellue suggests that the species was in San Francisco, California prior to 1870, and in southern California by 1890. [7] In Canada flowers are produced late in June and plants continue to bloom as long as the growing conditions are favorable. [5][37] Field bindweed can produce seed within one season of germinating. [6] Repeated cultivation is required for field bindweed control because plants can regenerate from roots as deep as 1.5m. The Atlas of Florida Plants provides a source of information for the distribution of plants within the state and taxonomic information. In Canada, growth begins when day temperatures are near 20oC and night temperatures are at least 14oC. [48][49]Swarz (pers. (1974)[15] suggest the following as general goals in the control of field bindweed: 1. reduce seed in soil, 2. prevent seedling growth, 3. deplete food reserves in the root system, 4. prevent spread of the weed. The amount of field bindweed that can be safely eaten by sheep, cattle, and goats is not known. 1927. The extensive roots can measure 6.6m long and penetrate deeply into the soil.[4]. Contact herbicides such as paraquat kill only tissue that they contact (“chemical mowing”), and should only be used for short-term control of field bindweed.[6]. Almost all current recommendations for cultivation also prescribe some herbicide treatment. [50] This suggests that competitive planting or restoration efforts in low light riparian habitats, where the available light is reduced by tree canopies, may work to control field bindweed. Convolvulus arvensis is a species of bindweed in the morning glory family, native to Europe and Asia. Convolvulus ambigens House : Convolvulus incanus auct. [10], The number of seed per plant varies between 25-300. [42] Callihan et al. Post-emergence applications of glyphosate for field bindweed and hedge bindweed control. Dicamba is effective against broad-leaved plants, like 2,4-D. Host specificity and biology of. Both adults and larvae feed on the leaves of many members of the Convolvulaceae. MacDonald, R.T., J.C. Hall, J.J. O’Toole, C.J. [6] Under dry conditions the application can be made later in the summer if the vines become more vigorous. [21], Application of 2,4-D under drought conditions allowed little control of field bindweed. Dunn, S. & S.C. Datta. [12] Plants with characteristics intermediate to those of these varieties are common in North America, further discouraging the use of the varietal names in the USA. There are other factors that may change the effectiveness of herbicides. 2,4-D is the most widely used herbicide because it controls the weed effectively and is relatively inexpensive. However, if the above-ground portion is allowed to regenerate and feed the root system, the plant can continue to flourish. 1976. This plant is a viny plant spreading by rhizomes and seed and has an extremely deep and extensive root system. [10] Seeds sown at two-week intervals had various germination rates—60-75% (spring), 44-57% (early summer), and 1-10% (midsummer). Experiments with sodium chlorate and other chemicals as herbicides for field bindweed. Water-impermeable seed dormancy. CABI Publishing, Wallingford, U.K. Conners, I.L. There is there is a great deal of information on field bindweed’s effects upon crops, but little is known about its impacts on rangelands or natural areas. & S.C. Weller. 1979. [10] Germination of fresh seed is not stimulated by light. [69], A single application in the fall in Lincoln, Nebraska demonstrated that 0.84 kg/ha glyphosate provided only 50% control but 1.7kg/ha provided 85% control.[70]. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. Growth chamber and greenhouse trials in Indiana studied the effects of adjuvants on field bindweed control. NativeIntroducedNative and Introduced. Bindweed while the leaves of Ipomoea pandurata (Wild Sweet Many Convolvulaceae can also become invasive. Wilson, H.K., L.M. & G. Campobasso. (1996)[21] suggest that drought (e.g. Gray, A. Weeds. Gray’s New Manual of Botany. Field bindweed control entails chemical applications, discing or hand-pulling on a regular basis (perhaps only once per year), plus yearly monitoring. Valentine D.H. 1975. Field bindweed is extremely persistent as seed (Porter & Brown, 1952). [10] While field bindweed might be troublesome in open, newly restored or old-field sites, it may be less persistent in an understory. Dybing. Tillage had no effect on control of field bindweed and under non-tillage conditions winter wheat, a cover crop, performed better. Convolvulus arvensis (field bindweed) is a species of bindweed that is rhizomatous and is in the morning glory family (Convolvulaceae), native to Europe and Asia. Post-harvest treatments for field bindweed control. Indiana Invasiveness Rank: Invasiveness Ranking Summary C. arvensis var. Food reserve depletion and synthesis in Field bindweed, Wiese, A.F., Salisbury, C.D., Bean, B.W., Schoenhals, M.G., Amosson, S. 1996. Picloram is a restricted-use herbicide and is registered only on rangeland and permanent pastures and on fallow grainland east of the Cascades. University of California Press, Berkeley, CA. 1991. 7:22-23. [21], At Rocky Ford, Colorado, dicamba at 2.2 kg/ha provided 93% control after four years. Dall’armellina, A.A. & Zimdahl, R.L. Kennedy. Field bindweed must be managed for several years to bring it under control. 1970. Convolvulus arvensis Taxonomy ID: 4123 (for references in articles please use NCBI:txid4123) current name Calystegia sepium L. is native to the eastern United States, but is now found throughout the country [16][6][17] and occurs in waste areas and fence rows.[6]. [1] The genus Convolvulus contains about 250 species (Zomlefer, 1994). The first true leaves are dull green and may be covered with fine granules on the upper surface. Whitworth, J.W. Sherrick, S.L., H.A. It was tested in the autumn, on pre-frost, wheat stubble (dry loam soil in North Dakota). Almost all research on field bindweed pertains to agriculture. (1.9-2.5 cm) across and are subtended by small bracts. In New York it was observed feeding on field bindweed and C. sepium to the point of complete defoliation while leaving other plants such as rye and corn were untouched. 2014; Mitchell et al. 1978. Cox, H.R. Application of 2,4-D at 1.1 kg/ha alone reduced infestations by only 73%. Comstock Publishing Association, Ithaca, NY. Knight. On the other hand, if it rains too soon after herbicide is applied, the herbicide may be washed off the plant or more rapidly degraded—for example, picloram is more rapidly broken down by microbes when water is abundant. Convolvulus species are referred to as bindweeds. Weeds 8:244. 1956. 1952. Proctor, V.W. (1996)[21] found a significant increase in available soil water following increased control of field bindweed in an agricultural setting. When the above-ground biomass of field bindweed is destroyed, the massive root system forms a new shoot and reserves are thus depleted. Leaves have a continuous, untoothed margin. Gray, G.P. Lym, R.G. Gaessler & W.E. & Lavake, D.E. Biological of hedge bindweeds of Long Island. Seed leaves (cotyledons) are nearly as broad as long, somewhat round, and notched at the tip. [6], A long-term perspective is important for a noxious perennial weed where total eradication is not a realistic short-term goal. Lateral and vertical roots become woody and store starch and sugars [4][12], presumably in the cortex and phloem. Flowers are similar to those of morning-glory, funnel shaped and white to pink in color having 5 united petals. The Nature Conservancy Weed Report for the Idaho Thousand Springs Preserve on. Picloram is known to remain active in soils for a number of years and may contaminate soils to 3m [53]so should not be used in the vicinity of orchards, vines and gardens [72], or water. [7] In Canada the name ‘liseron des champs’ (translation: field bindweed) may be used. Proceedings North Central Weed Control Conference, p. 30. Lee, D.W. Morishita. It is weak-stemmed and prostrate. [51] Callihan et al. In the first year the field was burned and planted with peas and oats. In greenhouse investigations, a glyphosate-susceptible biotype was controlled using 1.1kg acid equivalent/ha glyphosate while a more glyphosate-tolerant biotype required 4.5kg acid equivalent/ha to control. Derscheid, L.A., D.E. In natural environments, such as riparian zones, field bindweed (Convolvulus arvensis) competes with and displaces native bindweeds and other native plants. The use of perennial forage crops for the control of field bindweed at Scotland, ND. [6], Calystegia sepium L. (synonym: Convolvulus sepium L.), commonly called hedge bindweed, glory vine, or great bindweed, is a robust sprawling plant with large trumpet-shaped pale-lilac to white flowers that are approximately 5cm across. The Jepson Manual: Higher plants of California. It may not be as useful as other herbicides for management of preserves as it can persist in soil and damage other plant species. [7], Field bindweed is a persistent, perennial vine of the morning-glory family (Convolvulaceae) which spreads by rhizome and seed. The Alabama Plant Atlas is a source of data for the distribution of plants within the state as well as taxonomic, conservation, invasive, and wetland information for each species. Released in Texas in 1989 and established there, but its impacts are unclear to date. Chris and Mike O’Brien at TNC’s Thousand Springs Preserve had success controlling field bindweed in an agricultural site undergoing restoration, using a combination of tilling and planting competitive crops. Timmons, F.L. [59][60][61] If you plan to use an herbicide it is useful to know if field bindweed strains infesting the area are herbicide resistant. [7] Each flower is subtended by a pair of pointed, linear bracts located approximately 1.5-2.5 cm below the flower and often appressed to the stem.

Investigators suggest using adjuvant but at a concentration of 0.5% w/v to encourage absorption but avoid damage and subsequent decrease in translocation to the roots. When 96-190 cm long, some lateral roots begin growing downward. 1988. 2,4-D is the herbicides most widely used for field bindweed. [4] It is a weak-stemmed, prostrate plant that can twine and may form dense tangled mats. mallow bindweed. Piper, E.M. Coombs, C.E. Bean, C.D. 1986. Derscheid, L.A., D.E. Stahler, A.C. Arny, R.B. Applications were made once in the fall and every spring for four years. Field bindweed (, Hill, J. An extensive list of fungal species found on field bindweed in Canada is given in Conners (1967)[78]. [6] The species was present in every county in Idaho by 1955, occupying 570 km2 (140,000 acres) of cropland. [13] Convolvulus ambigens House is a hairy plant that has been grouped by Gleason (1952)[14] with C. arvensis. 1950a. & S.C. Weller.
