Potential Tutsan biocontrol agents

Tutsan (Hypericum androsaemum) is a shrubby weed from Eurasia that has become a major problem in the north of the North Island. It is spreading fast, and its presence leads to reductions in agricultural production. Here Hugh Gourlay looks at a couple of potential biocontrol agents that could help solve the Tutsan problem.
