    Preventative Measures: A Risk assessment of Cestrum nocturnum for Australia was prepared by Pacific Island Ecosystems at Risk (PIER) using the Australian risk assessment system (Pheloung, 1995). The result is a score of 16 and a recommendation of: reject the plant for import (Australia) or species likely to be of high risk (Pacific).

    In New Zealand C. nocturnum has been included in the Auckland Regional Pest Management Strategy as a "Research Organism" and as such there are no rules or regulations restricting their propagation and growth (ARC, 2007). It has not been included in the National Plant Pets Accord, primarily due to a lack of information on current distribution and potential effects (Biosecurity New Zealand, 2010). While not included in any other Regional Pest Management Strategies, C. nocturnum is apparently prohibited from sale in the Northland Region (Williams, 2008) and Cestrum spp. in the Bay of Plenty Region have been prohibited from propagation, sale and distribution (Environment Bay of Plenty, 2010).

    Physical Control: Small plants can be hand pulled all year round and left on site to rot down (Weedbusters, 2010). As stems can resprout and reinfestation can occur through the seed bank, bared sites should be replanted to prevent regrowth (Weedbusters, 2010).

    Chemical Control: Good control results for C. nocturnum have been reported using triclopyr ester at 20% in crop oil applied basal bark (Katie Cassel, pers. comm.; in Motooka, et al., 2003) with C. nocturnum probably sensitive to foliar application of triclopyr (Motooka et al., 2003). Cutting and painting the cut surface with a herbicide solution can be done all year round (Weedbusters, 2010) with Environment Bay of Plenty (2010) recommending the use of one part Tordon Brushkiller to 20 parts of water (50 ml / L), and Weedbusters (2010) recommending 100 ml / L of Tordon Brushkiller, 100 ml / L of triclopyr 600 EC or 500 ml / L of Yates Hydrocotyle Killer. Larger infestations should be sprayed (Environment Bay of Plenty, 2010), ideally in spring or summer (Weedbusters, 2010) with Environment Bay of Plenty (2010) suggesting the use of 50 ml of Tordon Brushkiller in 10 L of water and Weedbusters (2010) recommending the use of triclopyr 600 EC (30 ml/ 10 L) or Yates Hydrocotyle Killer (15 ml / L).
