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, addressing the logistical complexity of managing multiple crop cohorts at different developmental stages on Irish farms. The material synthesises established cereal disease management principles to support farmers in optimising disease control whilst navigating variable crop maturity across holdings. As applied extension material rather than experimental research, it likely draws on established agronomic practice and Teagasc trial experience.
Regional applicability
Directly applicable to Irish farming conditions and practice, particularly relevant to the variable spring barley establishment patterns typical of Irish cereal production. Timing and disease pressure principles may transfer to similar temperate maritime climates (including United Kingdom), though UK farmers should cross-reference with AHDB or local disease forecasting services for product approval and local pest pressure.
Key measures
Fungicide application timing relative to crop growth stage; product selection rationale for disease control
Outcomes reported
Guidance on optimal timing and product choice for final fungicide application on spring barley across multiple crop cohorts at different developmental stages.
