Heritability of glyphosate susceptibility among biotypes of field bindweed. [30] The roots and rhizomes become winter hardy in autumn and can withstand temperatures as low as -60°C. Whitworth, J.W. It is successful in many types of climates, including temperate, tropical, and Mediterranean, but is most troublesome for agriculture in the temperate zones where cereals, beans and potatoes are grown. Mulligan, G.A., J.N. The anatomy of. C. arvensis … 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. [6], A long-term perspective is important for a noxious perennial weed where total eradication is not a realistic short-term goal. Long-distance dispersal of seeds by retention in digestive tract of birds. PhD. Many parasitic organisms have been under investigation for control of field bindweed and one has been approved, but none have yet proven useful. Color, brightness and other floral characteristics attracting insects to the blossoms of some Canadian weeds. 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]. Most researchers suggest that herbicides be applied to field bindweed when the plant is most vigorous. Convolvulus arvensis Taxonomy ID: 4123 (for references in articles please use NCBI:txid4123) current name Food reserve depletion and synthesis in Field bindweed, Wiese, A.F., Salisbury, C.D., Bean, B.W., Schoenhals, M.G., Amosson, S. 1996. Meadows, fields, lawns, woodlands. Leaves have a continuous, untoothed margin. Salisbury, M.G. NativeIntroducedNative and Introduced. (1990)[6] suggest it was introduced to Virginia in 1739. Proceedings North Central Weed Control Conference p. 55-57. Leaves of this species are extremely variable, possibly reflecting variability in soil moisture and fertility. Mulch paper is black or dark and impervious to water. University of California, Agricultural Extension Publication, #4030. 2,4-D at 1.1 kg/ha plus dicamba at 5.6 kg/ha controlled field bindweed by approximately 90% after two years of treatment. Ahrens, W.H. They recommend tilling should be used after herbicide treatments. 1927. The outcome of competition between species can be complicated and unpredictable, but it appears the competitive balance between field bindweed and other species may depend mostly on soil water status ( Bakke, 1939). Hogs may eat the tops of field bindweed, and root deeply to eat rootstock, but as noted earlier, too much may distress them. The Nature Conservancy Weed Report for the northern Idaho Garden Creek Preserve on. Bakke, A.L., W.G. Where annual rainfall is low to moderate (27-50 cm) plants acquire attributes that deter absorption of herbicides, such as: lower leaf area, thicker cuticles, greater cuticular wax content, slowed biological processes, small leaf/root ratio [57], and vertical leaf orientation so herbicide rolls off. Field bindweed begins growing in the late spring or early summer and may persist until the first frost. [10], The number of seed per plant varies between 25-300. Proceedings of the Northeast Weed Control Conference 33:114. 1976. Fernald. Three to five growing seasons are required in agricultural settings to eliminate all seedlings. 1992. Water-impermeable seed dormancy. Scientific Name; COAM10: Convolvulus ambigens House: COIN7: Convolvulus incanus auct. 1995. An annotated index of plant diseases in Canada and fungi recorded on plants in Alaska, Canada and Greenland. Crafts, A.S. & P.B. Herbicides should be applied when they will be most effectively absorbed and translocated to the roots, but before the plants produce seed and new buds. The best average control (86%) was quinclorac at 0.375 lb/A plus glyphosate at 0.38 lb/A plus 2,4-D at 0.67 lb/A with Sun-It surfactant at 0.25 G (the wheat injury was 13%). 1959. Plunknett, J.V. The showy, funnel-shaped flowers of Convolvulus arvensis are unlikely to be confused with Polygonum convolvulus’s clusters of inconspicuous, greenish-white flowers. Field bindweed control by combinations of cropping, cultivation and 2,4-D. Weeds 8:397-401. ... (Convolvulus arvensis). The best control of field bindweed (96%) was achieved using 2,4-D at 3.4 kg/ha for one fall application and a mixture of dicamba at 0.28 kg/ha plus 2,4-D at 0.56 kg/ha for spring applications. The hairless leaves are entire and shaped like arrowheads with rounded tips. 1939. Gleason, H.A. Flowers usually measure 2-3 cm across and are found in clusters of 1-4 in the leaf axils. 2,4-D was more cost effective than dicamba (only $40-55/ha at the above rate). & M.L. (1997)[53] recommend using Landmaster BW (a mix of 2,4-D and glyphosate) at 0.43 to 0.75 kg acid equivalent/ha (54 oz/A) when bindweed runners are at least 25 cm long. Notes on some variations in field bindweed (. 1986. 1991. Isom. [7], Field bindweed is a persistent, perennial vine of the morning-glory family (Convolvulaceae) which spreads by rhizome and seed. [25] Bellue suggests that the species was in San Francisco, California prior to 1870, and in southern California by 1890. Effects of adjuvants and environment during plant development on glyphosate absorption and translocation in field bindweed (. (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. 1927. Meanwhile, O’Brien and O’Brien (1994) found that a very late fall application of Roundup and 2,4-D from a commercial spray rig did little to control field bindweed. 2,4-D is the herbicides most widely used for field bindweed. MacDonald, R.T., J.C. Hall, J.J. O’Toole, C.J. Near Bushman, Texas, the following treatments provided good control (97-100%) of field bindweed at the end of two years: A. tillage every three weeks and 2,4-D at 1.1 kg/ha through the growing season, plus one follow-up treatment to five-week old, vigorous field bindweed. Scientific Name: Convolvulus L. (Convolvulaceae) arvensis L. Related Plants. In northeastern Oregon on the Middle Fork Preserve, it occurs along roadsides and riparian areas (Youtie, 1994). The MON0818 and Tween 20 improved control. Light reduction (by smother crops or mulching) decreases field bindweed vigor (Gray, 1915). Washington Agronomy Experimental Station Popular Bulletin, #176. Absorption and translocation of glyphosate in tolerant and susceptible biotypes of bindweed (. Successful follow-up treatment formulations were: 2,4-D at 0.4 kg/ha and picloram at 0.6 kg/ha; 2,4-D at 0.4 kg/ha and picloram at 0.6 kg/ha plus dicamba at 2.2 kg/ha; 2,4-D at 1.0 kg/ha and picloram at 0.6 kg/ha plus picloram at 0.28 kg/ha. Latshaw, W.L. 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. Veins on the lower surface are raised. The researchers suggest that dicamba is more effective under drier conditions, while 2,4-D is more effective under wetter conditions. Field bindweed (, Hill, J. The biology of Canadian weeds. Alcock and Dickinson (1974)[15] find the species restricted to areas with available moisture throughout the summer and autumn in Australia. Some of the herbicides mentioned below, including 2,4-D, paraquat (Gramaxone®), and picloram (Tordon®) are restricted or prohibited in some states. & W.G. Field Bindweed leaves are shaped like an arrowhead with two pointed basal lobes that usually extend at right angles to the leaf mid-vein. [27][19] Gray (1970)[1] suggests a growth period of June to September for the northeastern United States. Flowers are usually solitary; bracts 3mm long; sepals elliptic-circular or oblong with petalsthat are white or pink or white-tinged pink, 2cm in length. 1964. Bindweed control in the Panhandle of Texas. [42][2] Bakke (1939)[45] in Iowa and Derscheid et al. Released in Texas in 1989 and established there, but its impacts are unclear to date. Meggitt, R.C. Cox (1915)[2] suggests that trees and shading help control the weed, and habitats that are most like agricultural lands (little competition, repeated disturbance and high light) are ideal for growth of field bindweed. Seely, C.I., K.H. Economic evaluation of field bindweed (, Youtie, B.A. Western Society of Weed Science, Bozeman, MT. There was no difference in efficacy of 2,4-D under tilled or non-tilled conditions, but the cover crop (winter wheat) did better under non-tillage conditions. 1974. It has long been known that field bindweed may proliferate if broken into small parts [2], and Frazier (1943b)[20] attributes resprouting to undamaged plant parts left underground. 1979. & F.H. Records of previous herbicide use may be helpful. They are arrange alternate each other on petioles. Gray, G.P. Control of noxious plants. Journal of the American Society of Agronomists 31:352-357. Bakke, A.L. Identify a weed; List of all weeds; Key to weeds in turf; Field bindweed, a perennial broadleaf, is considered one of the most problematic weeds in agricultural fields throughout temperate regions worldwide. The taxonomic treatment of polymorphic variation. Duncan-Yerkes, C.N. Jordan & W.H. Seedlings emerge from the soil erect and ascending. Manual of the Vascular Plants of the Northeastern United States and Adjacent Canada. [54] In any case, the herbicide should be applied before seed set. Spegazzini, C. 1923. Convolvulus / k ə n ˈ v ɒ l v juː l ə s / is a genus of about 200 to 250 species of flowering plants in the bindweed family Convolvulaceae, with a cosmopolitan distribution.Common names include bindweed and morning glory; both names shared with other closely related genera. Caterpillars of this European moth may defoliate field bindweed in the latter part of the growing season. An extensive list of fungal species found on field bindweed in Canada is given in Conners (1967)[78]. Proctor, V.W. European morning glory. Field bindweed: A growth stage indexing system and its relation to control with glyphosate. In the Pacific Northwest William et al. 1978.
