BIOSIS COPYRIGHT: BIOL ABS. Inkberry (Cestrum laevigatum Schlechtd.) is a small ornamental tree from South America which was planted widely in South Africa early this century. The young leaves and berries are poisonous to cattle and caused many deaths before this was known. It is a declared weed in terms of the Conservation of Agricultural Resources Act (Act 43 of 1983) but is not an aggressive plant because it has only become dense in localized areas where conditions are warm and moist, such as riverine vegetation. In the present study it was easily killed by triclopyr (3,5,6-trichloro-2-pyridinyl)oxy acetic acid) in diesel applies to the lower stem and root crown and triclopyr is now registered for the purpose at a rate of 4,8 g ai l-1. The same mixture and imazapyr (2-(4-isopropyl-4-methyl)-5oxo-2-imidazolin-2-yl) in water were also effective when applied to cut-stumps.
