[54], In an investigation in Lincoln, Nebraska during two very dry years (only 6.68 cm of rainfall in 1983 and 3.63 cm in 1984) studied the effects of September applications. in the Great Plains) may decrease the effectiveness of herbicides, perhaps because droughts or frost may cause plants to become dormant or semi-dormant. This species is present in most parts of the world where it has been accidentally introduced as a contaminant of both agricultural and horticultural seed. [13] Convolvulus ambigens House is a hairy plant that has been grouped by Gleason (1952)[14] with C. arvensis. & Muzik, T.J. 1967. Because of its wide distribution, abundance and economic impact, Convolvulus arvensis is considered one of the ten ‘world’s worst weeds’. Search for scientific names; Search for common names; Search by distribution; Info. Pancho, J.P. Herberger. Journal of the American Society of Agronomists 31:352-357. The researchers suggest that dicamba is more effective under drier conditions, while 2,4-D is more effective under wetter conditions. Proceedings North Central Weed Control Conference, p. 88. [64], Picloram (Tordon®) (note: first two entries based upon Down to Earth, a Dow Chemical publication.). Phillips (1978)[25] suggests that introduction to the Atlantic coast occurred around 1790, but Callihan et al. comm.) 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. 1939. Proceedings North Central Weed Control Conference p. 55-57. Swarz believes that the species will always exist as a minor component of the preserve. While 2.24kg/ha glyphosate reduced infestation levels to 24% under conditions of low humidity, in humid conditions control was only to 60%. CABI Publishing, Wallingford, U.K. Conners, I.L. Biological of hedge bindweeds of Long Island. Be sure to focus more effort on individual plants or populations that are tolerant to herbicides. 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. During fruiting, the sepals are retained. Proceedings North Central Weed Control Conference, pp27-28. It was tested in the autumn, on pre-frost, wheat stubble (dry loam soil in North Dakota). 1991. William, R.D., D. Ball, T.C. Entire. Hand sprayers provide more efficient coverage than large sprayers. (1996)[21] found that winter wheat in the Texas panhandle effectively controls field bindweed because it grows early in the season while most plants are still dormant, and reduces the available water. Field bindweed has deep roots that store carbohydrates and proteins. 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. Foraging patterns of Halictid bees at flowers of. It is considered a pest throughout the United States since it twines around crop plants and eventually topples them, although taller crops are considered to be at less risk. Frazier, J.C. 1943b. Derscheid, L.A., D.E. Gaessler. Wiese and Rea (1955)[48] and Wiese et al. [42][2] Bakke (1939)[45] in Iowa and Derscheid et al. Plant Physiology 2:503-506. Brown (1946)[13] found one plant was capable of producing 14 new shoots in one year. With diligence the roots can be removed leaving only the seedlings, however, even with intensive management field bindweed will persist as seed for several years. Flora of Tamil Nadu, VOL. Youtie successfully halted the spread of the species through herbicide application while Swarz controlled the weed with tillage and competitive species plantings. Economic evaluation of field bindweed (. Tests by William et al. Convolvulus arvensis is a species of bindweed in the morning glory family, native to Europe and Asia. Effects of adjuvants and environment during plant development on glyphosate absorption and translocation in field bindweed (. Some leaves are round, ovate or oblong, and some may even be linear. Canadian Journal of Botany 51:1939-1952. 1950a. In the Pacific Northwest William et al. (per Weaver & Riley 1982). [2] Like other weeds, field bindweed takes nutrients and water that would otherwise be available to desirable species . Managers are generally pessimistic about field bindweed control and question whether eradication is possible. Rank: Species. 1988. The MON0818 and Tween 20 improved control. Genus Notes: Calystegia is derived from within the Convolvulus lineage (Williams et al. If you decide to pull field bindweed it should be done frequently (see below for information on timing of cultivation). Field bindweed. The soil moisture relationship of European bindweed growing in corn. Growers Weed Identification Handbook. Control of field bindweed (. 1974. [8] Stems can grow to 1.5m or longer, and its underground rhizomes may range from 5cm to 2.6m long. Cattle will not readily graze on field bindweed and poisoning has been reported. Gaessler & W.E. Dall’armellina, A.A. & Zimdahl, R.L. Color, brightness and other floral characteristics attracting insects to the blossoms of some Canadian weeds. A 1% solution can be used for spot treatments. (1996)[21] found a significant increase in available soil water following increased control of field bindweed in an agricultural setting. Strong sunlight and moderate-to-low moisture appear to be optimal conditions for the growth of this species (Kogan, 1986; pers. Sa’ad, F. 1967. Field bindweed: Biology and management. Texas Agricultural Experimental Station Bulletin, #802. Petals are generally white to very pale pink. Reproductive systems and colonization in Canadian weeds. Dicamba is effective against broad-leaved plants, like 2,4-D. The petiole is flattened, and grooved on the upper side. Whitworth, J.W. Fischer, B.B., A.H. Lange, J. McCaskill. ... Nomenclature and Classification > Taxon Record Name > Scientific Name. [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. However, this mixture and others significantly reduced crop yields after two years.[64]. 1994. Basal lobes point inward toward the petiole. Oregon State University, 76pp. Glyphosate alone does not provide consistent control of field bindweed. 1950b. Some of the herbicides mentioned below, including 2,4-D, paraquat (Gramaxone®), and picloram (Tordon®) are restricted or prohibited in some states. [51] Callihan et al. 1950a. from the surrounding vegetation or restoration efforts), and continuous monitoring for resprouts. The flowers are tightly curled in buds. Absorption and translocation of 2,4-D in several annual broad-leaved weeds. B. no-tillage plus 2,4-D at 1.7 kg/ha after harvest in spring and a following applications to five week old vigorous field bindweed.
