This information will help you match fungicides to the primary disease risk(s) in wheat. Use it alongside our fungicide performance results and resistance management guidance to help maintain control within and across seasons.

Control level

• 5 = Highest
• 1 = Lowest
• - = Insufficient data (check label for information on activity)

Match fungicides to the primary disease risk. This depends mainly on variety, sowing date, location and local weather. Mixtures and alternations of fungicides, with different modes of action, from different fungicide groups, are often most effective and reduce the likelihood that fungicide resistance will develop in pathogens. Resistance poses a significant threat to the performance of fungicides and resistance management must be taken into account when planning fungicide programmes. Fungicides are tested by AHDB in specific performance trials and in other research projects targeting specific diseases. Performance ratings are indicative and are dependent on dose and timing.

[] based on limited or old data

$ Different products may contain different loadings and formulations which may impact on control level.

** Significant resistance risk. Always use SDHI fungicides in mixture with at least one fungicide from an alternative mode of action group which has efficacy against the target pathogen(s).

*** Key products may have significant differences between performance in protectant and eradicant situations, scores shown are for protectant situations.

# Ear blight caused by Fusarium culmorum or Fusarium graminearum. Performance against Microdochium species may differ.
