Introducing Mike Cripps
In his new role at AgResearch Mike is investigating biocontrol options for Californian thistle (Cirsium arvense) and shares two stories with us on his current work evaluating the effectiveness of the green thistle beetle (Cassida rubiginosa) and the fungal rust pathogen, Puccinia punctiformis.
What Do Zebra Chips Have to Do with Broom Biocontrol?
There are now six species of Liberibacter known worldwide, all vectored by different psyllid species, including the broom psyllid (Arytainilla spartiophila), and they are associated with some serious plant diseases.
New Project to Begin
An application to develop biological control for field horsetail (Equisetum arvense), put forward by the Lower Rangitikei Horsetail Control Group (LRHCG) to the Ministry for Primary Industries’ Sustainable Farming Fund, has been successful.
New Agent Approved
In January the Environmental Protection Authority approved the release of a fourth biocontrol agent for tradescantia (Tradescantia fluminensis) in New Zealand.
