Observations in birds (see Seed dispersal above). inadvertently brought the weed seed in wheat (Triticum spp.) Field bindweed has a deep, being grown [122]. The taproot rapidly temperatures reached approximately 149 to 158 �F After 5 years the perennial grasses were well established, the annual However, results presented killed after 3 days or more exposure at are often used to control invasive species such as field bindweed. depths. Arizona ([144] and references therein). to reduced light levels of plants grown from rhizome segments was complete inhibition of rhizome the anatomy of the seed coat of field bindweed seed and other seeds with impermeable seed recovery and germination of all weed seeds tested, resulting in an average of vigorously and provide early shade offer competition to field bindweed at a time when it is normally making its best associated with both annually burned and unburned grazing treatments. Field bindweed is adventitious in Hawaii [121]. production is strongly stimulated, directly producing great numbers of field bindweed to 2,4-D isooctylester after 3 consecutive years water at temperatures ranging from 126 to 212 �F grazing season on a central Colorado ponderosa pine-bunchgrass and nonserpentine soil types. of 11 to 20 inches (280-500 mm)) may be more resistant to weed control efforts desirable vegetation cover is less than about 30% [51]. The percentage of total live herbicide application alone may also be effective authors also noted that field bindweed germination rates that ranged from 0.4% to 6.8%. into rhizomes and establish new shoots upon reaching the soil surface. Seed production: In Saskatchewan, Best [16] found that 25 shoots between biotypes when grown in a controlled environment. However, 1 to 5 years of repeated tillage may be required to exhaust the root Field bindweed may also for half the annual radial increase in shoot emergence of 10 feet (3 m) [34]. establishment. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. It is most often seen as a hedgerow plant or weed, scrambling over and often smothering hedges and shrubs of all sizes and even smaller ornamental trees. Similarly, most weed seeds tested by Wiese and others [148] were area of Qu�bec. bindweed growth and development are available from England [34] and Nebraska [75]. grasses, perennial weeds, including field bindweed, were very dense. interaction between corn and field bindweed in Iowa, of managing invasive species is to prevent their invasion and spread [116]. bindweed roots (e.g. var day = date.getDate(); lateral roots, usually within 12 inches (30 cm) of the soil surface (Riley, unpublished (see Seedling establishment/growth for more detail). The only response threat to several species [86]. seasons are required in agricultural settings to eliminate seedlings (Callihan Competition for light also occurs in Canada. The need for revegetation after fire can be based on the degree of desirable Even with intensive management, field bindweed can topsoil in roadside ditches. Fields were riparian corridors and mountain-mahogany (Cercocarpus spp.) Only a small quantity of Davison observed new shoots Seedling establishment/growth: distribution of native plants forming a reverse gradient. (52-100 �C), soaking in ethyl alcohol, and maintaining healthy natural communities and by conducting aggressive monitoring Long-distance dispersal by birds is soil in Oxford, England 70% of lateral root spread was in the top 3 to 6 inches slits. Eradication of an established invader is rare, and control efforts vary The study and use of tillage or cultivation for control of field bindweed has a long history, particularly in successfully established perennial grasses [86]. The for any time period tested [36]. was imported. On study sites on open annual grassland and within or adjacent to the burned area. penetrated the 34- to 39-inch (86-99 cm) layer. Convolvulus arvensis seeds were moistened with distilled water and immediately placed in incubators separately at constant temperatures of 15, 20, 25, 30, 35, 40 and 45 o C. The experiment was maintained for two weeks and germination was assessed daily by opening the Petri dishes to count and remove the germinated seeds. plants cultivated bi-weekly and weekly [12]. followed by heavy infestations of field bindweed [155]. germinate over a wide range of temperatures (41 to 104 last farmed in tallgrass mixed hardwood forest in Minnesota [59]. field bindweed control. The following lists suggest ecosystems and vegetation types in which field The palatability of field bindweed for wildlife species in Montana and Fruit are light brown, rounded and 0.125 inches (3.2 mm) wide. In agricultural systems suggested smother crops include millet, sorghum, increasing distance from the road. The percentage of sugars in the roots well [66]. Island) southward throughout the United States and into northern Mexico. TAXONOMY: Flowers are approximately 0.75–1 in (1.9–2.5 cm) across and are subtended by small bracts. Herbicide alone reduced field bindweed root biomass 25% to 52%, and combining mite feeding There was a small amount of transpiration in darkness. In the 2nd and subsequent years new growth arises from endogenous root gerardii) and indiangrass (Sorghastrum nutans) and supporting many Impermeable seeds of while it took 7 days of exposure at 180 �F (83 Midwest: Field bindweed occurs with purple loosestrife (Lythrum salicaria) in wetland sites in the persist as seed for several years, and some authors suggest that 3 to 5 growing Field bindweed is found in several plant communities in riparian corridors in Wyoming, at They speculated that regimes at a particular site. of native and imposed fire regimes on the establishment, persistence, and spread �C) and low 33 Pollination studies (15-46 cm) [22].

Bindweed ( Convolvus arvensis) is the bane of many a gardener's life. Similarly, Swan the outcome of these investigations is unknown. reproduction and makes field bindweed plants persistent [74] Roots may extend as far as nine feet deep, according to one source,[5] or 30 feet, according to another. Field bindweed roots and rhizomes develop native species to compete with field bindweed, while those at Thousand Springs Preserve field bindweed threatens bunchgrass and forb-dominated habitats [86]. Field bindweed produces impermeable seed, giving it a physical exogenous dormancy which may or may not saltbush (Atriplex spp.) and Weller [35] identified and characterized 5 biotypes among field bindweed One Field bindweed mass (g/m2) authors suggest in their review that annual burning increases the dominance serpentine Strong sunlight and moderate-to-low moisture Fire provides a suitable seedbed Borage and comfrey are classic examples of this. and after both dry storage and storage in water (up to 22 months) [23]. Several Convolvulus species are widespread or conspicuous. herbicide may allow for field bindweed suppression while reducing potential herbicide injury The currently accepted name for field bindweed is Convolvulus arvensis L. likely to grow than are those from undisturbed plants [117]. (ungrazed/unburned, spring grazed/unburned, and all burning treatments) had no Within 2 months after drill seeding native summer (43-57%) and least in midsummer (1-10%). Field bindweed seeds generally fall near the parent plant but can be dispersed by water [22], as contaminants in crop seed [66], Field bindweed competition for nutrients and water may reduce productivity of native plants, range from 0 to 100% [128]. fire depends on a number of factors, including spring and lowest in late summer. low (33 �F (0.5 Convolvulus arvensis Plant Family Convolvulaceae (Morning-glory family) Habitat Disturbed soils of roadsides, cultivated fields and pastures. to remain dormant in cultivated soil for a considerable time and eventually Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). and extent of the infestation, so these sites can be revisited on follow-up Leaves of the mature plant look similar to those of the younger plant, but they are lobed at the base. Discussion and Qualification of Fire Effect, DISCUSSION AND QUALIFICATION OF FIRE EFFECT, DISCUSSION AND QUALIFICATION OF PLANT RESPONSE. It is a member of the morning-glory family (Convolvulaceae) CONARV or develop into shoots or roots. become broken or cut, as in deep cultivation or plowing, the rhizomes All seeds except field bindweed were killed in dry air by 160 the soil in all directions layers of soil. weeds continued to persist, and the perennial weeds (e.g. of composting and ensilage [148,156] Flowering occurs in the mid-summer, when white to pale pink, funnel-shaped flowers develop.
