solution to tutsan. Next steps for TAG:  To make more farmers aware of the plant, to keep an eye out for it and once spotted, encourage them to spray. To highlight to regional council weed officers and roading authorities because roadside mowing spreads the seed.  Highlight that biocontrol is the best option to tackle the entrenched infestations that infest and re-infest pasture.  Landcare Research is hopeful that a new rust will be found to attack the plant here. A rust is the most likely biological control agent that will be found as there are several endemic species of Hypericum in New Zealand and rusts tend to be very host specific, meaning less chance of target damage.  To date, a stem-boring moth and a foliage-feeding beetle have been identified in Europe (photos below).  Two types of tutsan have been identified in New Zealand. One originating from the UK (found in the South Island) and one from Europe (found in the North Island).
