Summary of InvasivenessTop of page
I. xanthiifolia is a summer to autumn flowering annual herb native to North America. It produces allergenic pollen, which can induce allergenic diseases and moreover it is a competitive weed in agriculture. It has been introduced to several European countries and occurs most frequently in the warm and continental parts of central and eastern Europe. Because of its significant potential impact on public health and land use, future spread of the species should be monitored and management strategies (e.g. raising awareness, early control) should be implemented (Follak et al., 2013).

Notes on Taxonomy and NomenclatureTop of page
I. xanthiifolia causes contact dermatitis and its pollen is a known agent of hay fever. That this species causes hay fever may be inferred from its common name of "false ragweed" (Pruski et al., 2005). The other frequently used names (marsh-elder, sumpweed) indicate its occurrence in its native range on sandy and silty river alluvials in dry river and stream beds (“in arid soils, near Fort Manden, etc, on the bank of the Missouri”; Jackson, 1960).
DescriptionTop of page
I. xanthiifolia is a summer annual species of 30–200 cm tall. The stem is thick, coarse branching, greyish-green, and arising from a taproot. Leaves are broad, mostly opposite, light grayish-green, ovate, 5-20 cm long and 2.5-15 cm wide, and coarsely toothed. Flowers are greenish-yellow, with greatly reduced corollas, crowded on branching spikes at the top of the stem and upper leaf axils. Male and female flowers are found on the same spike. The achenes are grey to black, triangular with a ridged surface and 2.3-3.8 mm long. In its native range in the north central and north-eastern states, pollen anthesis occurs from July to September. Pollen grains are tricolporate, spheroid to oblate, ranging in size from 18-20 μm in diameter. Furrows are long, approximately 10-14 μm in length, with pores 2.0 μm in longitudinal diameter (Flora of North America Editorial Committee, 2014; Weber, 2002).
Plant TypeTop of page
DistributionTop of page
I. xanthiifolia occurs particularly in western North America (Prairie States) and it can occasionally be found southwards near the Mexican border and in California. It has spread to eastern North America, where it may be found in the northern USA and adjacent Canada. It is found in the more temperate zones of the southern USA, but not in the Gulf Coast subtropical zone (Jackson 1960; Canadensys, 2014; USDA-NRCS, 2014).
Since the middle of the nineteenth century, and in particular the middle of the twentieth century the plant was introduced to many countries throughout Europe. Today, I. xanthiifolia is present in warm continental lowlands (Danubian Lowland and the Pannonian Basin) of Eastern Europe. Invasion hotspots are in southern and eastern Slovakia (districts Bratislava, Nitra, Košice), northern Serbia (Vojvodina), south-eastern Hungary (counties Csongrád and Békés) and eastern Germany (e.g. Dresden Basin) (Follak et al., 2013). Larger populations can be found in the Ukraine and southern and central Russia (Protopopova, 2006; Afonin et al., 2008; Abramova and Nurmieva, 2014).
Throughout most of the other countries in western and northern Europe, I. xanthiifolia is uncommon except for some large cities and areas along main rivers like Rhine (Ruhr, Mainz, and Mannheim) and Elbe (Hamburg). In mountainous regions in the Alps (Switzerland, western Austria) and Carpathians the species is nearly absent (Follak et al., 2013). Further introductions have been recorded for the Far East of Russia (Aistova et al., 2011), the Caucasus (Armenia; Pruski et al., 2005) and New Zealand (Heenan, 2004).

History of Introduction and SpreadTop of page
The invasion of I. xanthiifolia in Europe two main causes: (1) planting in botanical gardens and accidental dispersal and (2) introduction by and transportation of contaminated grain and oil seeds.
I. xanthiifolia first appeared in the Ukraine in 1842 and in Germany in 1858 in the area of Kiev and Potsdam and their vicinity, respectively, through seed dispersal from specimens grown in the local Botanical gardens (Swies and Soroka, 1998; Follak et al., 2013). In Germany, these early introductions were most likely temporary, whereas in Ukraine, the plant expanded its range and became occasionally naturalised building up a secondary distribution area (Guzik and Sudnik-Wojcikowska, 1989; Swies and Soroka, 1998). In other European countries, this species was detected much later. These introductions have been caused by the mass import of grain and oil-seeds (feeding material, but also for human consumption) contaminated with seeds of I. xanthiifolia from infested regions of North America and from its secondary range in the former USSR (Jehlík and Dostálek, 2008). Early records were from the beginning of the twentieth century in Switzerland, UK and Belgium (Verloove, 2006; Stace, 2010; Follak et al., 2013). In Poland (in its contemporary borders), the plant was first collated in 1931 (Wroclaw), in Austria in 1942 (Vienna), in Slovakia in 1934 (Šurany and Ciky), in the Czech Republic in 1947 (Prague), in Hungary in 1950 (Mezohegyes) and in Serbia in 1966 (Novi Sad). In Slovenia and Croatia, I. xanthiifolia was first recorded as late as in 1970 (Škofije) and 1976 (Ðurdanci), respectively (Follak et al., 2013). One of the latest findings was from 1996 in Kostinbrod/Bulgaria (Milanova, 1999).The rapid invasion of I. xanthiifolia has continued across Eastern Europe (Follak et al., 2013).

Risk of IntroductionTop of page
New introductions of I. xanthiifolia may occur through contaminated grain and oils-seeds although propagule pressure by this pathway may be less important, due to effective seed cleaning, high quality standards and changed terms of transport. Currently, the movement of soil and gravel contaminated with seeds of I. xanthiifolia by agricultural machinery or machinery used for construction work is presumed to be an active pathway of dispersal.
The spread of I. xanthiifolia in Eastern Europe appears to be associated with land use, with the species increasingly found in ruderal habitats associated with transport infrastructure (Follak et al., 2013). It is therefore possible that I. xanthiifolia will spread further via roadsides and along railways. In the Vojvodina region of Serbia, Radanovic et al. (2012) found roads and railways to be the primary routes for range expansion for I. xanthiifolia. It has also been frequently found along the rivers Rhine and Elbe, where ship ports provided a point of entry.
Follak et al. (2013) predicted that I. xanthiifolia is most likely to spread further in the lowland regions in the east and south of Eastern Europe, as opposed to the cool mountainous regions in the Alps and most parts of western Germany and Croatia. They listed invasion hotspots as southern and eastern Slovakia (Bratislava, Nitra and Košice districts), northern Serbia (Vojvodina), south-eastern Hungary (Csongrád and Békés counties), the easternmost part of Austria (Burgenland, Lower Austria) and eastern Germany (such as the Dresden Basin).
Edler and Steinmann (2012) concluded that further establishment of I. xanthifolia in northern Germany was most likely in humus-rich soils, although they noted that under changing climatic conditions the spread of the plant in northern Germany may be hampered. Conversely, Follak et al. (2013) reported that even moderate climate warming would result in a significant distribution increase of I. xanthiifolia in Central and Eastern Europe.
HabitatTop of page
Records of I. xanthiifolia are predominately associated with anthropogenically disturbed areas. Most populations grow on waste land, dump sites, along fences and on waste heaps. Moreover, ruderal habitats associated with transport infrastructure like roads and railway areas are regularly invaded by this species (e.g. Guzik and Sudnik-Wójcikowska, 1989; Swies, 1993; Jehlík, 1995; Swies and Soroka, 1998; Radovanovic et al., 2012; Follak et al., 2013; Follak, 2014). As a segetal weed, I. xanthiifolia was probably first found 1925 in the Ukraine (Guzik and Sudnik-Wójcikowska, 1989). In other European countries, it started to invade crop fields since the late 1960s. Early records in crop fields have been observed in 1968 in Slovakia by Krippelová (1969), in 1970 in Hungary by Terpo-Pomogyi (1975) and in 1974 in Serbia by Sainovic and Koljadzinski (1978). It is currently a common agricultural weed in the Slovakian Danubian lowland, Vojvodina and the Southern Great Plain in Hungary, Ukraine and Russia (Afonin et al., 2008; Vrbnicanin et al., 2009; Novak et al., 2009; Follak, 2014). I. xanthiifolia rarely colonizes river banks or other natural and semi-natural habitats (i.e grassland, forest edges) (Jehlík et al., 2005; Radovanovic et al., 2012).

Hosts/Species AffectedTop of page
I. xanthifolia has been recorded infesting sugarbeet fields in Serbia (Marisavljevic et al., 2005). In Hungary, encroaching I. xanthifolia threatens spring-sown row crops, such as sunflower, maize and sugarbeet (Zalai and Németh, 2007). It can also cause considerable damage to sunflower plantations in Hungary (Hódi and Torma, 2000).

Growth StagesTop of page
Biology and EcologyTop of page
The chromosome number of I. xanthiifolia is 2n=26.
I. xanthiifolia reproduces by seeds. The plant has a high fecundity under controlled conditions with a production of 90,000 to 120,000 seeds per plant as demonstrated by Hunyadi et al. (1998). Milanova (2001) showed that the number of seeds per plant varied approximately from 35,000 to 50,000 with a maximum of 105,000 seeds. Seeds remain viable in the soil for up to six years (Abramova and Nurmieva, 2014). Under field-grown conditions, seed production was on average 6,500 in central Russia (Republic of Bashkortostan) (Abramova and Nurmieva, 2014).
Physiology and Phenology
Seedlings emerge from late March to end of April under Central European conditions (Csongrád/Hungary). The seeds require burial for maximum emergence, with optimal burial depths from 1 to 3 cm (Hodi and Torma, 2002). According to Jehlík (1998) seeds start to germinate at a minimum temperature of 6°C to 10°C. The plant is very competitive and a fast growing species with the highest biomass increase in the second half of June and the first half of July (Hodi 2005).
In the lowlands of Slovakia (Šurany, Košice), individual plants reached a height of >300 cm (Krippelová, 1969; Follak, 2014). Lower plant heights have been recorded in central Russia ranging from 72.2 cm (Transural Republic of Bashkortostan) to 128.9 cm (Cisural Republic of Bashkortostan) (Abramova and Nurmieva, 2014).
The association of I. xanthiifolia to ruderal and segetal plant communities has been studied for different European countries (incl. Russian Federation), e.g. Froebe and Oesau (1969), Krippelová (1969), Šainovic and Koljadzinski (1978), Sudnik-Wójcikowska (1987), Swies and Soroka (1998), Kropác and Mochnacký (2009) and Abramova and Nurmieva (2014). These studies show that I. xanthiifolia prefers ruderal annual pioneer communities (Sisymbrietea, Chenopodietea) and, to a lesser extent, communities dominated by perennial herbs and grasses (Artemisietea). It has been suggested that occurrences with a large presence of I. xanthiifolia may be distinguished as a vegetation community in the rank of an association (Ivaetum xanthiifoliae). However, Sudnik-Wójcikowska (1987) and Swies (1993) suggested that those occurrences should be regarded as a derivative plant community, i.e. a poorly characterized rankless plant community devoid of any character or differential species.
I. xanthiifolia is a summer to autumn flowering annual herb and is susceptible to frost. In Slovakia, I.xanthiifolia is most favoured by conditions of at least 540 to 680 mm precipitation per year, as well as high summer temperatures in July and August (average temperature in July 18.5°C to 20.5°C) (Lhotská and Slavík, 1969). The authors concluded that the plant needs more than 100 days above 15°C to complete its life-cycle. The physico-chemical soil properties have been studied by Swies (1993) for ruderal communities in Lublin/Poland. There, plants grew most often on newly-laid heaps composed of loam, silt and sand formation mixed with concrete and bricks, rich in humus and calcium, potassium, phosphate and magnesium compounds. The soil pH was between 7.3 and 8.3. I. xanthiifolia requires full light and will not grow under shade. In its introduced range, in the former Czechoslovakia, the majority of records were found below 250 m a.s.l (Lhotská and Slavík 1969). In Vojvodina, 80% of the recorded populations by Marisavljevic et al. (2007) were below 100 m a.s.l. However, individuals have been found at altitudes ranging from 1040 m (Austria; Janchen, 1951) to 1450 m (Armenia; Pruski et al., 2005). Milanova (2001) found that the optimum soil depth required for emergence of the seeds is 1-2 cm in sandy loam soils.

Soil TolerancesTop of page
Natural enemiesTop of page
Means of Movement and DispersalTop of page
Seeds of I. xanthiifolia lack adaptation to specific modes of natural dispersal. Most seeds fall near the parent plant. Dispersal may occur by water (hydrochory) as seeds are able to float (Froebe and Oesau, 1969; Milanova and Valkova, 2004).
In the past, import of grain and oils-seeds from infested regions in North America and the former Soviet Union and its trade within European countries was most responsible for the accidental introduction of I. xanthiifolia (Jehlík and Hejný, 1974; Jehlík and Dostálek, 2008). New introductions of I. xanthiifolia may occur by this pathway although propagule pressure may be less important, due to effective seed cleaning, high quality standards and changed terms of transport. The movement of soil and gravel contaminated with seeds of I. xanthiifolia is presumed to be a very active pathway of dispersal. Seeds of I. xanthiifolia can be spread from field to field by agricultural machinery (harvester, plough). In the Vojvodina region of Serbia, Radanovic et al. (2012) found roads and railways to be the primary routes for range expansion for I. xanthiifolia.

Impact SummaryTop of page
Economic ImpactTop of page
I. xanthiifolia can locally invade several crops and may cause substantial yield losses. It has become an important agricultural weed in the Slovakian Danubian Lowland, Vojvodina in Serbia and the Southern Great Plain in Hungary, whereas in other countries in Central and Eastern Europe it only occasionally colonizes fields (Follak et al., 2013).
In North America, I. xanthiifolia is a competitive weed mainly in sunflower and soybean in the Midwestern States (USDA, 1971; Olson et al., 2011). In Europe, the plant is a weed in several countries (e.g. Novak et al., 2009; Vrbnicanin et al., 2009; Follak, 2014). It occurs mainly in sunflower, maize, soybean and sugar beet, because these crops are sown late in spring, have wide row spacing and a late crop covering, which favours germination and growth of I. xanthiifolia. It may be also found in winter and spring cereals and winter rape (Týr and Vereš, 2012). If not controlled, I. xanthiifiolia is a competitive and vigorous plant, which overgrows the crop and thus can induce high yield loss. However, interference studies are almost not available either from North America or from Europe. Effects of various densities of I. xanthiifolia on yield of maize and sunflower have only been documented by Hodi (2005). They looked at maize and sunflower in Hungary and found that as few as four weed plants/m2 could result in a yield reduction in maize of 50% and the presence of 12 plants/m2 resulted in an 80% loss in yield when compared to the control. The damage assessment in sunflower showed that 12 weed plants/m2 reduced the yield by nearly 60%. Lactating cows that ingest I. xanthiifolia leaves produce bitter-tasting milk (CBIF, 2009).
Environmental ImpactTop of page
As I. xanthiifolia is restricted to ruderal habitats and arable land, which are of minor importance for biodiversity, no impact on nature conservation is expected.
Social ImpactTop of page
I. xanthiifolia is an important inducer of allergic diseases like rhinitis, conjunctivitis, and asthma according to Wodehouse (1971) and Weber (2002). It is characterised as a “severe allergen” by Pollenlibary.com (2014). Contact dermatitis from this plant was reported by Huber and Harsh (1932) and Frain-Bell and Johnson (1979). Unfortunately, specific pollen hypersensitivity studies for Europe are not available (Mari et al., 2009). However, recent spread of I. xanthiifolia in Lublin (Swies, 1993) was reflected by the occurrence of significant pollen concentrations in the air as demonstrated by Weryszko-Chmielewska et al. (2003). Likewise Ado et al. (1980) showed that the aerial spectrum of Saratov/Russia has been found to contain high pollen concentrations of I. xanthiifolia. Along with Ambrosioa artemisiifolia it is the primary source of allergens in Romania in the summer (Hodis¸an, 2009).

UsesTop of page
Wang et al. (2007) suggested that I. xanthifolia could be used to substitute some components of young rabbit forage, as it was palatable to them and had no toxic effects.
Detection and InspectionTop of page
I. xanthiifolia can be easily detected in the field and identification keys can be found in the Flora of North America Editorial Committee (2014). It can be confused with species of the genera Ambrosia or Xanthium. Although the inflorescence of Xanthium strumarium agg. and I. xanthiifolia is completely different, young plants can be confused due to the similarity of leaf shape and habitus.
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.
Experimental field studies on the chemical control of I. xanthiifolia have been conducted in the USA, Serbia, Hungary and Slovenia in different crops such as sugar beet, soybean, sunflower and maize (e.g. Hodi and Torma, 2002; Hodi, 2005; Konstantinovic and Meseldžija, 2006; Marisavljevic et al., 2006; Macek, 2011; Olson et al., 2011). The authors concluded that I. xanthiifolia can be effectively controlled with standard applications of pre- (PRE) or post-emergence (POST) herbicides in these crops with herbicides with different mode of actions (e.g. acetochlor, metribuzin, imazamox, dimethenamid + phenmedipham + ethofumesate, tembotrione, sulfentrazone).
However, in North America, the widespread use of acetolactate synthase (ALS)-inhibiting herbicides (imazamox, tribenuron-methyl) has already resulted in the selection of resistant I. xanthiifolia biotypes (Heap, 2015).
The choice of physical and mechanical options depends on the population size and phenological state. Mechanical options include uprooting, cutting, and hoeing. Uprooting of plants before flowering and seed ripening is efficient for small to medium sized populations. Mowing is used to prevent seed production and exhaust plants in large populations. Time of mowing or cutting is crucial, as the plant may recover and produce seeds.
Gaps in Knowledge/Research NeedsTop of page
From Follak et al. (2013):
'Because of their significant potential impact on public health, future spread of I. xanthiifolia [in Central and Eastern Europe] should be monitored and management strategies (e.g. raising awareness, early control) should urgently be implemented.'
