Issue 221 Crop Action

Perennial ryegrass (Lolium perenne L.) is the main ryegrass species grown for seed in New Zealand, supporting both pasture and turf markets. Canterbury leads production, with around 12,000 ha sown annually. This study pulls together results from ten Canterbury field trials to assess how different fungicide programmes and timings affect seed yield. It compares early versus late applications and offers practical advice to help growers improve rust control and maximise returns.

This book outlines trial-specific yields and individual cultivar disease ratings for autumn sown wheat and barley cultivars included in the 2025-2026 CPT trials.
