Chemical: Cremer (2003) reporst that, \"The main method of controlling S. Cinerea is injection of stems with the weedicide Glyphosate. Painting of freshly cut stems with Glyphosate is particularly effective and the spraying of foliage of shorter plants (< 2m tall) is often effective as well.\" S. Cinerea can sometimes be resistant to this treatment of painting freshly cut stems and may need to be painted several times. Effectiveness is increased if the bark is also sprayed if it is thin or stripped if it is thick (Cremer, 1999).
Biological: The introduction of a biological agent has been considered for control of S. Cinerea in New Zealand, but opposition to the intentional introduction of further non native organisms is likely (Syrett, 2002). As other countries explore the possibilities of biological control agents, similar opposition will most likely arise also.
Harman (2004) has researched and identified a varying number of possible biological control agents for S. Cinerea. The author gives a brief introduction and background on these species and while many species appear promising, extensive research is needed before any agent is ever released. First, each varying degrees of research must be conducted to determine which species have a narrow host range. This is critical to the success of a biological control program for S. Cinerea in New Zealand. There are many Salix hybrids that are beneficial and are used extensively for riverbank protection and soil stabilization and any introduced agent must be specific enough to not damage desirable hybrids and other species present in New Zealand.
