Summary of Invasiveness

Top of page

Ipomoea carnea subsp. fistulosa is a species of morning glory that has been introduced worldwide as an ornamental and hedge (living fence) plant. The species has escaped from cultivation to become naturalized and invasive mostly in disturbed sites, riparian areas and wetlands, and it behaves as a weed in cultivated fields, such as rice plantations. It is a strong competitor for resources (e.g. nutrients and water), with the potential to outcompete native plants. The species has been listed as a noxious weed in the USA and as invasive in India, Nepal, Egypt, South Africa, Swaziland, Cuba, and in many islands in the Pacific region.

Notes on Taxonomy and Nomenclature

Top of page

Ipomoea is a large and complex genus of vines and shrubs within the Convolvulaceae (Stevens, 2012). The family comprises approximately 700 species grouped in 55-60 genera and is nearly cosmopolitan in distribution, although its members are primarily tropical plants (Stefanovic et al., 2003). The genus Ipomoea includes more than 600 species distributed worldwide, with approximately 500 species occurring in tropical and warm temperate regions of the Americas (Miller et al., 1999).

The taxonomy of many Ipomoea species, including Ipomoea carnea subsp. fistulosa is still unclear and has been the subject of extended discussion. There are nomenclatural problems with what has been called I. fistulosa, I. carnea subsp. fistulosa and I. crassicaulis. These three names have been used extensively in the literature as distinct taxa, but also as synonyms and subspecies of I. carnea. Verdcourt (1963) noted a close relationship between I. fistulosa and I. carnea, while Austin (1977) listed I. fistulosa as a subspecies of I. carnea, although with a different geographical and altitudinal range. On the other hand, the name I. crassicaulis has been commonly synonymized with I. fistulosa. Authors have noted that the taxonomic confusion may be due to the morphological plasticity observed when these plants grow in wet and dry habitats and to their extensive cultivation as ornamentals (Verdcourt, 1963; Austin, 1977; Frey, 1995; Shaltout et al., 2006).

History of Introduction and Spread

Top of page

I. carnea subsp. fistulosa has been intentionally introduced worldwide as an ornamental and hedge plant, and has been repeatedly reported as escaped from cultivation (PIER, 2017; PROTA, 2017; USDA-ARS, 2017). By 1963, the species was reported as “cultivated and naturalized” in tropical East Africa (Verdcourt, 1963). In 2015, it was collected in Saudi Arabia, where it grows as a hedge plant around cultivated fields in the Jazan region (Al-Sodany, 2016). It was probably introduced by the Indian or Egyptian farmers working at these farms.  

Risk of Introduction

Top of page

The risk of introduction of I. carnea subsp. fistulosa is high, because the species is still widely cultivated as an ornamental around the world. Seeds can be easily obtained online on horticulture websites (e.g. Dave’s Garden, 2017).  

Habitat

Top of page

I. carnea subsp. fistulosa is able to grow in a wide range of habitat types, from aquatic to xerophytic conditions (PROSEA, 2017). It grows as a weed in disturbed sites, forest margins, open woodlands, grasslands, gardens and fences, and it also grows along waterways, in riparian areas, irrigation channels, swamps and wetlands. It can sometimes grow on beaches (Frey, 1995; Henderson, 2015; Flora of China Editorial Committee, 2017; PROSEA, 2017). 

Hosts/Species Affected

Top of page

I. carnea subsp. fistulosa is considered a serious weed in cultivated rice fields due to its strong competitive ability (Frey, 1995).

Growth Stages

Biology and Ecology

Top of page

Genetics

The chromosome number reported for I. carnea subsp. fistulosa is 2n = 30 (Flora of China Editorial Committee, 2017).

Reproductive Biology

I. carnea subsp. fistulosa is a perennial and fast-growing species, able to spread vegetatively from stem fragments and by seed (Henderson, 2015; PROSEA, 2017; USDA-NRCS, 2017). Stem fragments can set root within a few days, while decumbent branches root in the soil and grow upwards, becoming new ramets (Al-Sodany, 2016). Individual plants can thus easily expand, covering dozens of square metres. Reproduction by seed is also common. During winter, the dry fruit-wall splits and the hairy endospermic seeds are dispersed, although they do not germinate immediately due to their hard seed coat, which is impervious to water (Eid, 2002).

Physiology and Phenology

I. carnea subsp. fistulosa flowers throughout the year, except during cool periods. Pollinators include butterflies and bees from the families Hesperiidae and Apidae and the subfamily Xylocopinae (Frey, 1995; PROSEA, 2017).

Environmental Requirements

I. carnea subsp. fistulosa is well adapted to tropical, sub-tropical and warm temperate environments, where it grows at elevations from sea level up to 1000 m (PROSEA, 2017). The species can also grow in waterlogged sites, such as swamps and wetlands, up to 2 m deep in the water (Henderson, 2015). I. carnea subsp. fistulosa is not tolerant of shade (Frey, 1995).

Notes on Natural Enemies

Top of page

In Bolivia, Lepidoptera larvae and Coleoptera parasitize the leaves, stems and seeds of this plant. The beetle Megacerus flabelliger (Bruchidae) feeds on the seeds of this species and has been suggested as a potential biological control agent in India (Frey, 1995). Also, the Ipomoea-specific oomycete plant pathogen Albugo ipomoeae-panduratae, white rust, attacks the apical leaves and stems of I. carnea subsp. fistulosa (Frey, 1995).

Means of Movement and Dispersal

Top of page

Natural Dispersal

I. carnea subsp. fistulosa spreads by seed and vegetatively from stem fragments (Henderson, 2015). Seeds are covered by a dense cottony, furry indumentum, consisting of slightly glossy and thick hairs that facilitate wind and water dispersal (Al-Sodany, 2016).

Accidental Introduction

During floods and other natural disasters, plants are swept off river beds and embankments and can become established in habitats downstream.

Intentional Introduction

The species has been widely introduced by humans across tropical and subtropical regions worldwide, primarily to be used as an ornamental and hedge plant (Henderson, 2015; PROSEA, 2017).

Economic Impact

Top of page

I. carnea subsp. fistulosa is considered a serious weed in rice fields and is listed as a weed in pastures (Frey, 1995; Oliveira Júnior et al., 2014). In aquatic habitats, it can form floating mats on the water surface, causing problems such as obstruction, difficulties in irrigation and navigation, and also causing problems for fisheries (Chaudhuri et al., 1994).

Environmental Impact

Top of page

I. carnea subsp. fistulosa is an environmental and agricultural weed. This invasive species has been reported displacing native vegetation in Nepal, Egypt, South Africa, Swaziland, Cuba, and on many islands in the Pacific region (Tiwari et al., 2005; Chandra Sekar, 2012; Oviedo Prieto et al., 2012; Henderson, 2015; PIER, 2017). It has become a serious weed in Swaziland and South Africa, where it is also regarded as a serious threat to wetland habitats (Henderson, 2015; Swaziland National Trust Commission, 2017). In India, it is also invading riparian areas and irrigation channels (India Biodiversity Portal, 2017). In Egypt, it invades canal and drain banks, roadsides and field edges in the Nile Delta (Shaltout et al., 2006).

Social Impact

Uses

Top of page

Economic Value

In India, the plant is grown as a source of green manure. It also shows potential for biogas production due to the high cellulose and volatile solid content of its dried stem material. In some states in India, the species is used as a raw material for paper-bag production (Frey, 1995; PROSEA, 2017; USDA-ARS, 2017).

Social Benefit

The species is used in traditional medicine, especially as an antirheumatic remedy and a topical antiseptic for lesions. The leaves are slightly purgative and eaten as a vegetable, although they are considered toxic to livestock.

Environmental Services

I. carnea subsp. fistulosa is cultivated as an ornamental plant for its attractive flowers, and as a hedge plant along irrigation banks and drainage canals (e.g. Eid, 2002).

Prevention and Control

Top 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.

Control

Physical/mechanical control

Although manual control of I. carnea subsp. fistulosa by stem cutting and digging is commonly undertaken, it is costly and often not very effective. Any stems and seeds remaining in the soil can easily and rapidly re-infest cleared areas. Nevertheless, a study has shown that in Brazil, where the species grows as a weed, I. carnea subsp. fistulosa was effectively controlled by mowing plants in the early dry season, when their production and capability to resprout are reduced (Haase, 1999).

Biological control

I. carnea subsp. fistulosa seeds are heavily infested by the beetle Megacerus flabelliger, which has been suggested as a biological control agent in areas where this plant is a troublesome weed (e.g. India). However, an uncontrolled release of the beetle could have devastating consequences for the crop Ipomoea batatas and its hundreds of associated economically important varieties (Frey, 1995).

Chemical control

The herbicide 2, 4-D (2, 4-dichlorophenoxy acetic acid) is known to be effective against Ipomoea species, including I. carnea subsp. fistulosa. Doses of 1 to 3 kg in 0.05% aqueous solution usually provide over 90% control. Regeneration of about 10% of the original number of plants occurred in areas sprayed at doses of 1 to 2 kg, but not when higher application rates were used (Chaudhuri et al., 1994).

Gaps in Knowledge/Research Needs

The role of the beetle Megacerus flabelliger as a potential biological control agent for I. carnea subsp. fistulosa, as well as its potential effect on native species, should be further studied.
