This Cereal Update outlines priorities for cereal fungicide applications with a focus on the T0 (GS30-31 end of tillering/start of stem elongation) timing. It includes a decision tree for T0 applications.
- FAR data suggest T0 applications rarely pay their way, even on susceptible cultivars and in high disease pressure seasons.
- Supported by the Fungicide Resistance Industry Initiative, FAR has developed fungicide timing priorities, resistance management guidelines and decision trees.
- The four level priority system is based on the value provided by applications at different timings.
- T0 fungicides are considered a priority three and should only be considered when the season or disease situation demands.
- T0 fungicides are required where stripe rust or powdery mildew are present.
- A T0 Decision Tree has also been developed to support decision making around T0 applications.
