Summary of Invasiveness
Top of pageS. rostratum is a taprooted annual plant known to be a noxious weed in parts of the USA and Canada, and is included in the Global Compendium of Weeds as an ‘agricultural weed’, ‘casual alien’, ‘environmental weed’, ‘naturalised’, ‘noxious weed’, and ‘weed’ across tropical and temperate regions of the world (Randall, 2012). It is a fast-growing, vigorous weed native to Mexico and the United States and now widely introduced including into Europe, Asia and Oceania. The species invades ecosystems by forming dense colonies, and a single plant can produce hundreds of seeds (Vallejo-Marin, 2014) which are dispersed by both biotic and abiotic vectors, as well as self-propelled by its dehiscent fruit (Whalen, 1979). The species is a declared noxious weed in the U.S. states of Idaho, Hawaii, Oregon, and Washington state (USDA-ARS, 2014), and is listed in the FDA Poisonous Plant Database (FDA, 2014).

Notes on Taxonomy and Nomenclature
Top of pageSolanaceae, the Nightshade family, consists of 90 genera and 3000-4000 species with great variation in habit and distribution on all continents except Antarctica, with the majority of species diversity in Central and South America (PBI Solanum Project, 2014).
Solanum is one of the largest genera of vascular plants with 1000-1500 species, around 1000 of which are speculated to be of American origin (Hunziker, 1979). Taxonomy of the genus and its seven subgenera have undergone many revisions, but the overall genus consists of herbs, shrubs, trees, or herbaceous or woody vines, usually with spines or prickles, glabrous or pubescent with simple or stellate hairs (Acevedo-Rodriguez, 1996). The Solanum genus includes the wild potato, S. tuberosum, the tomato, S. lycopersicum, and the eggplant, S. melongena, with many other members cultivated for medicinal and ornamental uses. While the etymology of the genus’ scientific name is unclear, it may be derived from the Latin word “sol”, meaning "sun," referring to its affinity for sunlight, or from the Latin word “solare”, meaning "to soothe”, the Latin word “solamen”, meaning "a comfort", or the Akkadian word “sululu”, meaning “happy”, in reference to the narcotic effects of some Solanum species after ingestion (Smith, 1971; Wiart, 2006; Quattrocchi, 2012; NZPCN, 2014).
The genus Solanum has been divided into seven subgenera, which are further divided into sections and subsections. The species Solanum rostratum belongs to the prickly Solanum subgenus Leptostemonum and the section Androceras. The Androceras section consists of c. 12 species and is an unusual Solanum section, as it is characterized by mostly north temperate distribution and distinctive zygomorphic, heterantherous, and enantiostylous flowers and prickly calyx tubes that tightly and completely encase the berries (Whalen, 1979; Stern et al., 2010).
In the literature this species has often and incorrectly been called Solanum cornutum, which is distinct from Solanum cornutum Lamarck. The species name rostratum is derived from the Latin word for “beaked”, in reference to the shape of its flowers (Smith, 1971).
Description
Top of pageIndividual plants reach 1-1.5 m tall, with once- or twice-pinnatifid leaves, and abundant prickles on the stems and leaves. It produces yellow flowers with pentagonal corollas 2-3.5 cm in diameter and weakly bilaterally symmetric (Whalen, 1979). In its native range S. rostratum is pollinated by medium- to large-sized bees including bumblebees (Bowers 1975). Flowers bear two sets of anthers that are unequal in size and may be distinctly coloured (Vallejo-Marín et al.. 2009). The fruit, a berry, is enclosed by a prickly calyx and the seeds are released when the berries dry and split while still attached to the plant. [Taken from Vallejo-Marin, 2014].
Distribution
Top of pageS. rostratum is considered native to Mexico, where it exhibits the greatest genetic diversity (Zhao et al., 2013), as well as to the United States particularly the Great Plains region (Whalen, 1979), and it is widely naturalized and invasive in tropical and tropical regions around the world (Randall, 2012; USDA-ARS, 2014). As an introduced species it is not as common in Africa or India, being a relatively recent introduction there (Deb, 1979; Jaeger and Hepper, 1986), as it is in Australia, where it has in some parts been labeled an agricultural and environmental weed (Randall, 2012).

History of Introduction and Spread
Top of pageS. rostratum is an annual weed originating from the Americas (USDA-ARS, 2014). The species may have migrated north across the USA via cattle or horses from northern Mexico and Texas (hence the common name ‘Texas nettle’) (Todd, 1882; DuBois et al., 1896; Tower, 1906), although it may also be native (USDA-ARS, 2014). S. rostratum was reportedly in Colorado by 1877 and Illinois and Tennessee by 1888 (DuBois et al., 1896). It may have then spread by trade routes connecting the Americas to Asia and elsewhere, as suggested by recent research indicating a shared origin of populations in China with U.S. populations (Zhao et al., 2013). The species was introduced to the British Isles sometime in the 1800’s (Vallejo-Marin, 2014).
Although it is native to North-Central America, S. rostratum does not appear to be widespread or weedy in South America; it is not included, for example, in Forzza et al.’s (2010) flora of Brazil or Funk et al.’s (2007) work on the Guianea Shield. The species was also a ‘recent’ introduction to Africa as of 1986 and is lower priority for invasive concern on this continent (Jaeger and Hepper, 1986).
S. rostratum is a recent introduction to Asia. Som Deva (1976) reported it as a new record to India in 1976. In China, it was first recorded in Liaoning province in 1981, but has since spread across a large area in northern China, where there is ongoing dispersal (Zhao et al., 2013).
Risk of Introduction
Top of pageS. rostratum is widespread in North America, Asia, Australia, and parts of Europe (Randall, 2012). It is known to be toxic to livestock and is included in the FDA Poisonous Plant Database (FDA, 2014). The seeds are dispersed by water, wind, humans and mammals (DEPI-AU, 2014; Vallejo-Marin, 2014), as well as self-propelled by its dehiscent calyx (Whalen, 1979). The species has the potential to grow as a weed on roadsides, agricultural fields, and other disturbed sites (Vallejo-Marin, 2014), and is a seed contaminant of grains, fodder, and soil (Wiersema and Leon, 1999; EPPO, 2001; DEPI-AU, 2014; PBI Solanum Project, 2014). However, it can be well controlled with herbicides. In North America it is generally confined to the wheatbelt and is a strong competitor for cotton crops (DEPI-AU, 2014), and the species’ high competitiveness is often associated more with crop plants in agricultural settings than with native flora. In Victoria, Australia, S. rostratum is not yet known to invade natural ecosystems, although its “spiny nature and toxic fruit may have minor impact on non-threatened fauna” (DEPI-AU, 2014). Considering the toxicity, traits, known invasiveness and widespread distribution, the risk of introduction for this species is high especially in areas near agricultural settings.
Habitat
Top of pageS. rostratum assumes a tight, congested habitat, preferring to colonize sunny, open places, such as disturbed areas, roadsides, abandoned agricultural fields, and dry streambeds (Whalen, 1979). As an agricultural weed it is also found in managed cultivated settings.
Chinese populations usually grown in open, disturbed habitats such as roadsides, fallow fields and along train tracks (Zhao et al., 2013).

Biology and Ecology
Top of pageGenetics
The chromosome count for S. rostratum is n=12, 2n=24 (Vallejo-Marin, 2014).
Reproductive Biology
S. rostratum is pollinated by as many as 11 different genera of bees, including smaller mining bees and five Bombus species (Bowers, 1975; Symon, 1979).
Physiology and Phenology
S. rostratum takes less than a year to become productive; in North America the species germinates in autumn, grows in winter and flowers in late spring and summer (CSU, 2014), The species can reportedly reach reproductive maturity within 4-6 weeks of germination (Vallejo-Marin, 2014). It reproduces by seeds, which its dehiscent fruits propel upon drying and bursting (Whalen, 1979). Each plant can produce 40-80 berries (PBI Solanum Project, 2014), and individual plants have been recorded to produce over 78,000 seeds (Lin and Tan, 2007).
Associations
Both S. rostratum and S. elaeagnifolium are ancestral host plants of the Colorado potato beetle, Leptinotarsadecemlineata. This parasite is considered to have adapted to the potato plant, S. tuberosum, as its’ new host when the American settlers introduced it (Casagrande, 1985).
Environmental Requirements
The species demonstrates resistance to both drought and waterlogging, but prefers dry, exposed soil with plenty of sun (Parsons and Cuthbertson, 2001; CSU, 2014; DEPI-AU, 2014).

Cw - Warm temperate climate with dry winter | Preferred | Warm temperate climate with dry winter (Warm average temp. > 10°C, Cold average temp. > 0°C, dry winters) |
Means of Movement and Dispersal
Top of pageS. rostratum reproduces by seeds, which are numerous and dispersed by both biotic and abiotic vectors. The species has the ability to self-propel its seeds by its dehiscent berries (Whalen, 1979; CSU, 2014). Seeds are also dispersed by water, as the fruit can float (DEPI-AU, 2014), and by the wind, as this species is a common tumbleweed (Whalen, 1979; CSU, 2014). Its prickly fruit easily attach to wool, clothes, and manmade items by which humans may aid in its dispersal. It is also likely that dispersal is facilitated by accidental transport in contaminated grain or forage as it often grows on the margins of crop fields (Zhao et al., 2013). The species is also known to have escaped cultivation (Randall, 2012).

Economic Impact
Top of page
Negative economic impact is likely in areas where tourism is important, as dense, thorny colonies formed by the plant would deter people from passing the area. Similarly, livestock may avoid grazing areas in pastures where this species occurs. Regarding human and animal health, if ingested the plant is poisonous.
As S. rostratum is a weed of agriculture, the species negatively impacts crop production, not only by competing for resources and space, but also by contaminating seeds and products such as wool (DEPI-AU, 2014).
Environmental Impact
Top of pageS. rostratum poses a negative impact to the environment, as it forms dense colonies and, once established, is difficult to eradicate.

Uses
Top of pageS. rostratum is a noxious weed, but has reportedly been used in folkloric medicine to treat coughs (Duke, 2014).
Detection and Inspection
Top of pageIdentification is difficult, often resulting in agricultural seed contamination (Wiersema and Leon, 1999; DEPI-AU, 2014).
Prevention and Control
Top of pageDue 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.
S. rostratum can be physically uprooted from the ground, although the thorny species forms dense colonies, making this difficult. Thick gloves should be worn as protection against the spines.
Effective herbicides include Dicamba, Triclopyr and 2,4-D, and Glyphosate in a 2% solution can be applied as a spot treatment. Herbicides should be applied between late bud and early flower (CSU, 2014).
