Plant Protection Research Institute Handbook No. A complete guide to declared weeds and invaders in South Africa. Not listed as a noxious weed by the state or governments in Kenya, Tanzania and Uganda. The editors do not know of any biological control programmes targeted at this species. Slashed stems resprout so there must be follow up and retreatment as necessary to ensure that long term control is achieved. When using any herbicide always read the label first and follow all instructions and safety requirements. Plants can be cut down and stumps painted with a suitable herbicide. Roots can be buried deeply and the remaining plant material left to rot down on site. Plants can be hand pulled and the roots dug out roots (all year round). Consistent follow-up work is required for sustainable management. Control is generally best applied to the least infested areas before dense infestations are tackled. Controlling the weed before it seeds will reduce future problems. If prevention is no longer possible, it is best to treat the weed infestations when they are small to prevent them from establishing (early detection and rapid response). The best form of invasive species management is prevention. Some components of an integrated management approach are introduced below. The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species. purpurea has been listed as an invader in South Africa. Parts of this plant, including the seed are poisonous if ingested. Once established in areas of indigenous vegetation, it is able to outcompete native species for nutrients, water and sunlight. However, it also invades bushland and riparian zones (banks of watercourses) and can be a serious environmental weed in warm moist areas, where it chokes out native plants. crops, roadsides, parks, gardens, fence-lines and waste areas). Ipomoea purpurea is mainly a weed of agricultural areas and disturbed sites (e.g. Ipomoea purpurea was introduced as a garden ornamental and is still occasionally grown in gardens. Sepals finely pubescent all over corolla is white, pink or magenta, and white below. The stalk of the inflorescence ( peduncle) is up to 12 cm long. purpurea are solitary or in few-flowered cymes. The leaf blade is ovate (egg-shaped in outline with broad end at base), entire or 3- lobed, acuminate (gradually tapering to a sharp point) at the apex, cordate (heart-shaped) at the base, glabrous or pubescent (hairy).įlowers of I. Stems of Ipomoea purpurea are hairy and may be trailing or twinning. Ipomoea purpurea is a herbaceous annual twining climber. Ipomoea purpurea invades waste and cultivated ground mainly in riparian (banks of watercourses), wetland and coastal habitats. In East Africa, it occurs in Mengo district (Uganda), Kiambu district (Kenya) and Lushoto district (Tanzania). Ipomoea purpurea is naturalised in parts of Kenya and has been introduced to Tanzania and Uganda. ![]() Introduced, naturalised or invasive in East Africa ![]() Ipomoea purpurea is widely naturalised in the tropics. The exact native range of Ipomoea purpurea is obscure, however it is thought to have originated in South America.
