Huge savings for economy from humble wasp

A humble Irish wasp has saved New Zealand almost half a billion dollars, AgResearch estimates. The estimates also show that the benefits of the introduction of the wasp by AgResearch to control the highly destructive clover root weevil are expected to continue at an ongoing rate of at least $158 million per year. The total […]

Scientists looking for answers as pests fight back

As concern grows worldwide about bacteria developing resistance against antibiotics, AgResearch scientists are looking into how common pests in New Zealand are also fighting back against traditional measures to control them – and whether it all comes back to evolution. Principal Scientist at AgResearch, Professor Stephen Goldson, is working with his colleagues in an area […]

NGB scientists battle kiwifruit disease

AgResearch scientists involved with the Next Generation Biopesticides (NGB) programme are playing an important part in the battle against a bacterium (Pseudomonas syringae pv. actinidiae) attacking New Zealand’s lucrative kiwifruit industry. Dr Sean Marshall, a microbiologist with AgResearch at Lincoln, is part of a team including Emily Gerard and David Wright (also from AgResearch) plus […]

Biocontrol beetle on show

Farmers will be able to observe first-hand the impressive impact of a biocontrol agent that acts against one of the country’s worst agricultural weeds at an upcoming field day hosted by AgResearch and Beef + Lamb NZ. The green thistle beetle (Cassida rubiginosa) was released in 2007 to help fight Californian thistle, a plant recently […]

Ongoing thistle control

Effective management of an invasive farm weed is becoming more simple and robust thanks to ongoing work undertaken by AgResearch scientists. Californian thistle is widespread throughout New Zealand pasture and during its seasonal peak, covers 12% and 6% of grazed land on sheep and sheep/beef farms, respectively, resulting in an annual national revenue loss of […]

Biocontrol beetle shows great promise

Farmers will be able to observe first-hand the impressive impact of a biocontrol agent that acts against one of the country’s worst agricultural weeds at upcoming field days hosted by AgResearch. The green thistle beetle (Cassida rubiginosa) was released in 2007 to help fight Californian thistle. It’s now established in several parts of New Zealand […]
