Chemical: For overall spray application, the following herbicides are suitable: Glyphosate (e.g. Roundup G2): knapsack: 100ml per 10 litres of water handgun: 1 litre per 100 litres of water NB: The addition of Pulse penetrant at a rate of 100ml per 100 litres water is recommended to improve herbicide uptake. Escort: knapsack: 5g per 10 litres of water handgun: 20g per 100 litres of water NB: The addition of Pulse, Boost or Freeway at 100ml per 100 litres of water will improve herbicide uptake. Tordon Brushkiller: knapsack: 100ml per 10 litres of water handgun: 1 litre per 100 litres of water. The stem cut and inject method is suitable for privet plants with a stem diameter of 50mm or more. Ring bark the base of the stem with downward axe/machete strokes, cutting into the sap wood. Apply herbicide to the point of runoff into each downward cut immediately after cuts have been made. Suitable herbicides and dilution rates for cut and inject treatment are: Glypohosate (e.g. Roundup G2): Use neat (i.e. undiluted) Escort: 20 g (+ 10ml Pulse penetrant) per litre of water Stump treatment Cut plant off about 50mm above ground level. Apply herbicide mixtures to top and sides of the stump. Pulse penetrant will aid uptake of the herbicide. Suitable herbicides and dilution rates for stump treatment of Privet are: Glyphosate: 2 litres (+10ml Pulse) per 10 litres of water Escort: 5g (+10ml Pulse) per 10 litres of water NB: Herbicide must be applied immediately after stumps have been cut. Herbicide is most effective when applied during Privet's active growing season - spring or autumn in fine weather. If using Escort, avoid use over or nearby desirable plants, or in areas where their roots may extend. (Environment B.O.P. 1998).
Biological: An investigation of possible biological control agents is under way on La Réunion. (Environment B.O.P. 1998)
