Pasture pests costing economy billions

25 September 2018

Pests most commonly targeting New Zealand’s pastures are costing the economy up to $2.3 billion a year, an AgResearch study has found.

The study is the first of its kind to estimate the financial impact of invertebrate pests such as the grass grub, black beetle, nematodes and weevils in terms of lost productivity for pastoral farming.

The full science paper has been published this week in the New Zealand Journal of Agricultural Research and can be found here:https://www.tandfonline.com/doi/full/10.1080/00288233.2018.1478860

Of the total estimated annual losses of between $1.7 billion and $2.3 billion in `average’ years, up to $1.4b billion occurs on dairy farms, and up to $900 million on sheep and beef farms.

“Our research shows that the impact of the grass grub alone costs dairy farms up to $380 million, and sheep and beef farms up to $205 million, each year,” says AgResearch scientist Colin Ferguson.

Losses attributable to these pasture pests are usually determined either on the basis of the amount of foliage they consume, or reductions in pasture production.

However, AgResearch’s study has used the reduction in pasture production to estimate the impact on milk production revenue for dairy farms, and on meat production revenue for sheep and beef farms.

“What this provides us is a good picture of the challenge we and farmers face with pasture pests, and it reinforces the need to invest in new and cost-effective ways to better control these pests,” Mr Ferguson says.

“AgResearch is looking at pest control on a number of fronts, including the development of new biopesticides – naturally occurring organisms that can be used to target specific pest species, instead of chemical treatments that can be expensive and have unwanted impacts on the environment.”

The study was initiated as part of Pastoral 21 Next Generation Dairy Systems and funded by DairyNZ, Fonterra, Dairy Companies Association of New Zealand, Beef + Lamb New Zealand and MBIE – and has been completed with funding from AgResearch.
