Summary
This 2026 Teagasc extension advisory from Crops Specialist Shay Phelan provides practitioner-focused guidance on final fungicide application timing and product selection for spring barley, accounting for the logistical complexity of managing multiple crop cohorts at different developmental stages on Irish farms. As applied extension material rather than experimental research, it synthesises established cereal disease management principles to support farmers in optimising disease control whilst navigating the practical constraint of variable crop maturity across holdings.
Regional applicability
This advisory is directly applicable to Irish spring barley growers and reflects Teagasc's extension service delivery. The phenological and disease management principles are likely transferable to similar temperate maritime growing conditions in the United Kingdom, though UK-specific cultivar choices, disease pressure, and regulatory frameworks may differ.
Key measures
Fungicide timing recommendations, product selection criteria, and phenological stage considerations for spring barley disease control
Outcomes reported
This advisory synthesises guidance on final fungicide application timing and product choices for spring barley crops at different phenological stages. It addresses the practical challenge of managing multiple crop cohorts with varying maturity across individual farm holdings.
