Ziziphus mauritiana (tree, shrub)
Physical: Mechanical techiques (eg bulldozing) must cut the shoot at least 25cm below ground level to avoid sprouting. Fire kills only a small proportion of the smaller plants (<1m high).
Chemical: Effective herbicides include triclopyr/picloram in a 1:60 herbicide-diesel mixture applied as a basal bark spray during times of active plant growth. The same chemical can be applied to cut stumps ay any time of year. It may also be effective in a high volume spray mixture of 0.35L herbicide:100L water to actively growing regrowth. Soil application of picloram-triethanolamine at 35-45 g/sq m can be used on dense infestations.
Biological: Biological control has not been attempted (Grice, pers.comm. 2002).
