![]() Solanum mauritianum is easily killed with herbicides applied as foliar, basal bark (painting herbicide onto the bark) or cut stump applications. Small plants may be hand-pulled but mature plants will re-sprout if they are cut down. 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. They serve no economic purpose and possess characteristics that are harmful to humans, animals or the environment) and Australia. It has been listed as a noxious weed in South Africa (prohibited plants that must be controlled. mauritianum has been included in the Global Invasive Species Database (GISD 2006). The fine hairs on the leaves can be an irritant. ![]() All parts of the plant are toxic to humans, especially the green berries. Solanum mauritianum can form dense stands that inhibit the growth of other species through overcrowding and shading. However, this use cannot compensate for this plant's overall negative impacts. Solanum mauritianum can be grown as a nursery plant. The upper leaf surface is green and glossy but the lower surface, leaf stalk and new growth is matted with clumps of soft woolly hairs. ![]() They are Clerodendrum tomentosum, whose leaves often have a purple leaf stalk, and Astrotricha latifolia, whose leaves are often held at an angle of nearly 90° to the leaf stalk. Two native shrubs or small trees, both typical of moist areas such as gullies and rainforest edges, can have large densely furry leaves, particularly on new growth. stelligerum usually has some prickles scattered on the stems, as do most native nightshades found on the south coast, but S. These also have furry grey-green leaves, but they are smaller and narrower, and the plants are usually only 1m high. There are smaller purple-flowered native nightshades ( Solanum species), of which the most similar are Solanum stelligerum (devil's needles) and Solanum densevestitum. Spread from seed in dumped garden waste, and dispersed by birds. It is poisonous for many other organisms, including humans (Olckersa and Zimmermann 1991). mauritianum is a favoured food plant of the African olive-pigeon ( Columba arquatrix). Its fruit are yellow globular berries (10-15 mm across). The flower is purple with a yellow centre are produced in dense branched clusters. One or two ear-shaped leafy structures are usually present at the base of the leaf stalks. Its large oval leaves are grey-green in colour and covered with felt-like hairs. Solanum mauritianum is a large shrub or small tree usually growing 1.5-4 m tall but sometimes up to 10 m. HabitatĪgricultural areas, coastland, natural forests, planted forests, forest margins, riparian zones (banks of watercourses), ruderal/disturbed, urban open spaces. ![]() It is particularly problematic in Uganda in degraded forests and its control is going to very costly as more forests become degraded abetting its further spread. obs.) and Uganda (Haysom and Murphy 2003) and it is present in Tanzania (A.B.R. Solanum mauritianum is invasive in parts of Kenya (A.B.R. Introduced, naturalised or invasive in East Africa Locations within which Solanum mauritianum is naturalised include Australia, southern Europe, tropical and southern Africa, southern USA and in many oceanic islands with warm climates. Native to South America (Brazil, Uruguay and northern Argentina). Solanum mauritianum (Bugweed) Scientific nameīugweed, bug berry, bug tree, bugtree, earleaf nightshade, flannel leaf, kerosene plant, tobacco bush, tobacco weed, tree tobacco, wild tobacco, wild tobacco bush, wild tobacco plant, wild tobacco tree, woolly nightshade. ![]()
