| Notes: | Spread by: vegetative material and/or seeds in garden waste, water, contaminated soil on machinery, vehicles etc; contaminated pasture seeds and contaminated forest mulch. Invades/threats: agriculture, particularly the sugar-cane industry, grazing and the environment. Notes: a serious environmental weed in this region invading roadsides, rainforest margins and vine thickets. More than 20 species of Ipomoea occur in this district with 15 of them being native. Only one native species has been identified as being a problem to agriculture so, as always, correct identification is essential. Exotic species that are now widely naturalised were probably all introduced as ornamentals. The hard seeds have a long viability and most perennial species are also spread by vegetative means. Environmental weed. |
