DescriptionTop of page
E. arvense has extensive and deep-seated rhizomes that are dark brown to black, dull, covered with hairs and occasionally bear tubers. The tubers are formed as shortened swollen internodes consisting of starch-filled cells traversed by a few vascular bundles (Korsmo, 1954). The rhizomes send out shoots each year.
The stems are annual, erect or decumbent, hollow and jointed, with sheaths at the joints. The fertile stems are unbranched, 10-25 cm high, terminating in a cone which may be 2.5-10 cm. The cone is formed of shield-shaped, stalked scales from which spores are produced. The spores germinate to produce the minute, sexual stage (gametophyte), which is seldom seen, from which the spore-bearing plants develop. The spores (33-48 µm in diameter) are globose and pale green to yellow. The fertile stem has large, easily separated joints, up to 8 mm thick. The sheaths are 14-20 mm long, with large, partly united teeth, 5-9 mm long, flesh-coloured yellowish or brownish. They are precocious and ephemeral. As small Arctic plants they occasionally persist and become branched and green (Tutin et al., 1964-1980). The sterile or vegetative stems are branched, 20-100 cm high, with smaller joints. The sheaths are cup-shaped, 5-10 cm long, gradually widening upward. The teeth are dark brown to light tan, free or partly united, 1.5-7 mm long, dry thin and membranaceous. The branches are 10-15 cm long with internodes 1.4-4.5 cm long and 0.8-4.5 mm in diameter. Internally, both carinal and vallecular collenchyma are present. Chlorenchyma is present under the ridges but is interrupted under the valleys. The central canal takes up 33-66% of the diameter of the stem.
E. arvense is adapted to dry conditions because it has a silica-coated cuticle, sunken stomata, reduced leaves and an assimilating stem, while the rhizomes bear hydromorphic structures (Borg, 1971). The hollow rhizomes facilitate the passage of air far down into the soil (Uchino et al., 1984) and serve as routes for the uptake of water (Borg, 1971). The roots of E. arvense also associate with several strains of nitrogen-fixing bacteria in a nitrogen-free mineral nutrient solution (Uchino et al., 1984).

Biology and EcologyTop of page
E. arvense reproduces by spores on the fertile stem, but primarily by extensive rhizomes. Williams (1979) reported that about 50% of the rhizomes occupied the upper 25 cm of the soil profile, 25% occur in the next 25 cm of soil and the remaining 25% in the next 25 cm of soil. Under some circumstances, E. arvense reproduce by tubers that grow out from the nodes of the rhizomes and which, detached from the rhizome, may serve as a vegetative propagule.
E. arvense is slow-growing (Andersson and Lundegårdh, 1998a). Rhizomes planted in March attain their maximum shoot growth in July, their maximum shoot height in August, their maximum shoot number in September and accumulate dry matter in the rhizomes until October. The tubers are initiated in late summer and grow in size and number until November (Kvist and Håkansson, 1985; Marshall, 1986).
E. arvense is adapted to sunny habitats. It is dependent on its rhizomes and tubers for growth under heavy shade. For maximum growth, E. arvense has a high potassium demand, especially at high nitrogen levels (Andersson and Lundegårdh, 1998b). The shade sensitivity of E. arvense can partly be explained by its small, scale-like, non-functional leaves at the nodes (Holm et al., 1977). The assimilating capacity of the stem of E. arvense is not known (Borg, 1971). E. arvense seems to be sensitive to direct light competition. However, unfavorable conditions that do not decrease light may favour it. E. arvense is tolerant of low levels of nitrogen but will be overtopped by fast-growing species when competing for increased supplies of nitrogen. An increase in nitrogen supply and reduction in light, both increase the reduction of rhizome dry weight, whereas tuber production can be favoured by low nitrogen supply and high light intensities (Andersson and Lundegårdh, 1998a).
E. arvense can tolerate extended periods without rain because its rhizomes can extend several metres down into the soil (Cloutier and Watson, 1985; Reuss and Bachthaler, 1988) to escape the effects of tillage and herbicides (Williams, 1979). The tubers on the rhizomes act as organs of storage and regeneration, but the tubers may also disseminate the weed (Holm et al., 1977). Tuber size increases with depth (Williams, 1979), contributing to the plant's strong regenerative capacity. It has been reported to emerge through silt layers up to 1 m thick following flooding (Holm et al., 1977).
Notes on Natural EnemiesTop of page
Herbivores that feed on E. arvense include ducks (Hauke, 1966), the homopteran Macrosteles borealis and the hymenopteran Dolerus spp.; the coleopterans Grypidus equiseti, Grypus spp. and Hippuriphila spp. are found associated with E. arvense (Cody and Wagner, 1981).
ImpactTop of page
E. arvense can be toxic owing to the thiaminase that is primarily found in its leaves and stems. Thiaminase is an enzyme that splits the B vitamin thiamine rendering it inactive. Hay containing this weed may be more poisonous than fresh plants in the field. Thiamine is involved in decarboxylation reactions in animals. Deficiency of thiamine leads to accumulation of pyruvate in the blood, with a resulting impairment in energy metabolism and cellular shortage of ATP. Hay that contains E. arvense at a level of 20% or more may produce symptoms of thiamine deficiency in horses in 2-5 weeks. Ruminants are not generally affected by thiamine deficiency because thiamine is made in the rumen (Henderson et al., 1952; Cheeke and Schull, 1985).
E. arvense is an astringent herb and has a diuretic action. Fresh E. arvense can be bruised and applied to wounds to stop bleeding (Hauke, 1978). It has also been used to treat deep-seated lung damage such as that caused by tuberculosis or emphysema (Ode, 1993). What makes E. arvense valuable as a medicine is its mineral and silica content. It contains up to about 7.4 % silica (Carnat et al., 1991). Silica is important in strengthening many tissues in the body including bone, hair and nails. It promotes calcium absorption and helps fight against plaque deposits in the arteries. Historically, the dried stems of E. arvense were used to polish pewter and other metals. Other chemical constituents are flavonoids (0.3%), potassium (1.8%), isquercitroside (0.12%), phenolic acids (0.7%), calcium (1.3%) (Carnat et al., 1991) as well as traces of alkaloids (nicotine, palustrine and palustrinine), saponins, phytosterols, tannins, and the minerals manganese, sulfur, and magnesium (Ode, 1993).
E. arvense accumulates heavy metals, which makes it a suitable indicator for heavy metals such as copper, zinc, cadmium and lead (Ray and White, 1979).

Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.Introduction
E. arvense has a prolonged storage phase in rhizomes and tubers, which lie deep in the soil, this gives it the potential to be a persistent and troublesome weed (Marshall, 1986; Andersson and Milberg, 1996; Andersson, 1997).
A 50-year study of E. arvense showed that annual cultivation, combined with the use of herbicides to control annual broad-leaved weeds, resulted in E. arvense becoming a dominant weed species. This implies it is highly sensitive to competition, with light as a main factor (Karch and Speri, 1979). A large study, conducted in Finland, shows that the abundance of E. arvense decreased significantly in spring cereals from the 1960s to the 1980s, probably due to improved cultivation techniques and new competitive crop varieties (Erviö and Salonen, 1987). Data from a long-term experiment have shown that E. arvense can become a dominant weed species in low-yielding crops receiving little or no nitrogen fertilizer (Andersson and Milberg, 1996). Williams (1979) showed that E. arvense has a weak response to nitrogen at levels corresponding to those given to agricultural crops. That E. arvense is sensitive to crop competition has also been shown by Cloutier and Watson (1985). Cultivation depletes the extensive underground food reserves of E. arvense. However, E. arvense is very persistent because of its extensive underground root and rhizome system. Soil compaction and prolonged cereal rotations (Bachthaler, 1985) increase the abundance of E. arvense. Repeated hoeing during one season has little effect on E. arvense (Cloutier and Watson, 1985) but minimum tillage in monocultures seems, after some years, to favour E. arvense (Légère, 1993).
The increased frequency of E. arvense in nitrogen-free fertilized plots in fields with increased amounts of potassium shows that potassium availability may restrict the growth of E. arvense even in soil unfertilized by nitrogen (Andersson, 1997). Consequently, nitrogen fertilization of crops under field conditions will not favour the growth of E. arvense, instead, it will be suppressed by increased light interception by the crop (Andersson and Milberg, 1996).
There is no effective chemical control for E. arvense. The use of selective foliage-applied herbicides (Marshall, 1984) has no pronounced long-term effect on E. arvense growing in crops because of its deep-rooted system of rhizomes and tuberous storage organs and an extended period of emerging vegetative shoots (Korsmo, 1954; Kvist and Håkansson, 1985; Marshall, 1986). Glyphosate, MCPA, dichlorprop and mecoprop have only a limited effect on the growth of E. arvense the year after application (Hallgren, 1996). There is large variation in the physiological activity of E. arvense which may partly be responsible for the lack of effectiveness of herbicides. However, July-October is significant for rhizome growth, tuber initiation and the sustained storage of assimilates in the underground system (Marshall, 1986). August applications of glyphosate gave consistently better control compared with those earlier in the season, presumably because the increased movement of assimilates during the late summer to the regions of active growth (rhizome apices, nodes, and tubers) is also conducive to translocation (Marshall, 1980).
