Fodder Grass

Abstract E. japonica is a good fodder grass cultivated for pasture in tropical and subtropical regions (Kumar, 2013; USDA-ARS, 2016). It has escaped from cultivation and naturalized principally in disturbed sites. This species behaves as a weed in abandoned pastures, cultivated land, disturbed sites, waste areas, and along roadsides and riparian areas (Barkworth et al., 2004; Flora of China Editorial Committee, 2016; PIER, 2016; PROTA, 2016). Currently, it is listed as invasive in Argentina, Brazil, and Cuba (Zuloaga et al., 2008; Oviedo Prieto et al., 2012; I3N-Brasil, 2016). It is well adapted to grow in seasonally waterlogged conditions and can be found growing in floodplain grassland and swampy grassland (Flora of Pakistan, 2016).

Eragrostis Atrovirens

Abstract Eragrostis atrovirens is a C4 grass cultivated for pasture and hay in tropical and subtropical regions (USDA-ARS, 2016). It has escaped from cultivation and once naturalized it behaves as a weed in roadsides, disturbed sites, waste areas, riparian areas, and grasslands (Barkworth et al., 2004; Flora of China Editorial Committee, 2016; PIER, 2016; PROTA, 2016). This perennial grass has the capability to tolerate drought and high saline conditions as well as seasonally waterlogged conditions. Thus, it can be found growing in floodplain grassland and swampy grassland (Flora of Pakistan, 2016). Currently, it is listed as invasive in Australia, Micronesia, Palau, Chagos Islands, Cuba, and Mexico (Villaseñor and Espinosa-Garcia, 2004; Oviedo Prieto et al., 2012; Simon and Alonso, 2016; PIER, 2016).

Abandoned Lands

Abstract C. rutidosperma is a common herb that grows as a weed in disturbed and ruderal habitats, principally in areas with humid and hot environmental conditions. It is often found as a weed of disturbed ground, roadsides, gardens, crops and abandoned lands, and has also been found growing as an epiphyte on trees, stone walls and cliff faces. This species is included in the Global Compendium of Weeds (Randall, 2012) where it is considered to have moderate economic impacts in a wide range of crops, due to its scrambling habit that smothers and stunts young crop plants. C. rutidosperma has been listed as invasive in China, Malaysia, India, Thailand, Vietnam, Australia, and the Domican Republic (Waterhouse and Mitchell, 1998; Kairo et al., 2003; Flora of China Editorial Committee, 2014, USDA-ARS, 2014). This species has had considerable environmental impacts in South East Asia and Australia. C. rutidosperma also has the potential to be moderately problematic in intensive cropping areas, greenhouses and nurseries.

Abstract E. tirucalli is a many-branched succulent plant widely commercialized as an ornamental, hedge plant, potted plant and for soil conservation (Orwa et al., 2009; USDA-ARS, 2016). It has escaped from cultivation and once naturalized, it often grows forming thickets mostly in disturbed sites, abandoned gardens, deciduous forests, semiarid sites, and along roadsides (Little et al., 1974; PIER, 2016). This species grows very fast, and produces a lot of biomass even under very marginal soil and extreme climatic conditions (Mwine and Damme, 2011). In invaded areas, it is propagating vegetatively by cuttings and stem fragments (Little et al., 1974; PIER, 2016). Currently, this species is listed as invasive in Hawaii and Cuba (Oviedo Prieto et al., 2012; PIER, 2016), but is listed as potentially invasive on many islands in the Pacific and in tropical and subtropical areas of Asia (Nguyen and Sosef, 1999; Flora of China Editorial Committee, 2016; PIER, 2016).

Abstract F. littoralis is a tufted leafy annual or short-lived herb (sedge) included in the Global Compendium of Weeds where it is listed as an agricultural and environmental weed (Randall, 2012). It has escaped from cultivation and become established along waterways and wetlands (Flora of China Editorial Committee, 2014). The species is of particular concern in rice plantations around the world (Holm et al., 1977). It shows allelopathic activity and once established it can change features of ecosystem functions including hydrological cycles, biophysical dynamics, nutrient cycles, and community composition (Holm et al., 1977; Holou et al., 2013).

Abstract Derris elliptica is cultivated mainly for its roots. The powdered root is widely used as a source of rotenone, which is considered an effective natural alternative to regular synthetic chemical insecticides used in horticulture and agriculture (Duke, 1981; de Padua et al., 1999; Orwa et al., 2009; Flora of China Editorial Committee, 2018).
