Giant buttercups

The buttercup that grows in many gardens is small compared with the giant buttercup (Ranunculus acris), which can reach waist height. Nationally it is estimated to cost $156 million in lost dairy production. It has developed a resistance to spray control, so AgResearch is investigating using a mycoherbicide (living plant pathogen) made from a fungus.
