Impact of fungicide selection on nitrogen utilisation

Nitrogen remains the fundamental building block to yield. Whilst grain prices continue to strengthen, fertiliser availability and cost remains challenging. Appropriate agronomy utilising proven inputs remains crucial to enhancing the benefit of any applied nitrogen, and maximising yield potential.

2022 AHDB report confirms the impact of reduced N on yield

  • For cereals with a current break even ratio of 10, reduce RB209 recommendation by ~50kg N/ha
  • A reduced N rate of 50kg N/ha is expected to reduce cereal yield by ~0.35 t/ha

Where does Revystar® XE fit if nitrogen availability is limited?

ADAS research in 2021 found that Revystar® XE was fundamental to building yield:

In 2021 where visual Septoria was low at the time of fungicide applications:

  • Varietal resistance reduced the yield drag of Septoria in the absence of fungicide.
  • For any given rate of applied nitrogen, Revystar® XE outperformed a conventional fungicide across the two varieties studied.
  • Revystar® XE achieved:
    • The same yield with a lower dose of N
    • Increased yield for any given rate of N
    • Improved economic margin of £70+ /ha
  • If N application is reduced, optimising disease control with Revystar® XE maximises yield potential and nitrogen utilisation.
Adjusting nitrogen rate has minimal effect on optimum fungicide choice.
