Genomics revolution promises greener future for New Zealand vineyards

Lincoln University and MGI Tech have teamed up to deploy advanced DNA sequencing, analysing tens of thousands of grapevine samples to identify genetic traits linked to disease resistance and resilience. Traditionally reliant on fungicides, New Zealand’s NZ$2.1 billion wine sector faces growing pressure from climate-driven disease threats and public concern over chemical use.

“The introduction of high-throughput sequencing has changed the game,” said Associate Professor Christopher Winefield of Lincoln University. “Instead of scheduled spraying, farmers can move to targeted, evidence-based treatments.”

Early results suggest significant reductions in chemical use, lower costs, and improved sustainability. The team plans to expand genomic tools across other crops and livestock, potentially transforming agriculture both in New Zealand and globally.
