Septoria tritici blotch (Zymoseptoria tritici) in wheat - a comparison of early control methods locations
Aims
  • To determine if grazing alone can reduce Septoria tritici blotch (STB) disease pressure.
  • To determine how long flutriafol, applied to the fertiliser, can control STB into the season.
  • To assess the efficacy of the preliminary SDHI seed treatment to control STB.
  • To assess whether the effectiveness of early control with grazing or seed treatments is improved with a foliar application of the foliar fungicide Opera (pryaclostrobin and epoxiconazole) at GS39 (flag leaf emergence).
Key messages
  • Dry conditions reduced the severity of septoria tritici blotch.
  • Timing of fungicide application did not affect (p<0.05) grain yield or quality.
  • Consider using seed or fertiliser fungicide treatment when grazing wheat early in the season.
  • Multiple fungicide applications using different active groups will reduce the risk of fungicide resistance developing in Zymoseptoria tritici.
  • Grazing can add feed value to the wheat crop and reduce disease pressure.
