New interactive cereal disease decision tree launched

Product Update

Syngenta has launched a new, online decision tree to help growers with fungicide decisions in winter wheat and in winter and spring barley.


Available at, the interactive decision tree takes into account factors such as variety resistance, whether the main target disease is yellow rust or Septoria in wheat, or net blotch, Rhynchosporium or brown rust in barley, and whether disease is anticipated or already present.


Syngenta disease expert David Ranner says: “This information is used to help users narrow down options among different types of fungicide active ingredient. Usefully, with yellow rust a heightened concern for this year, the tool will help users to identify the optimum spray timing to apply the fungicide Elatus Era.”


With the loss of chlorothalonil similarly a concern, the interactive decision tree also provides information on when to consider the alternative multi-site fungicide, folpet, says Mr Ranner.


“Other information included in the decision tree includes the use of mildewicides and the targeting of Ramularia in barley. With disease pressures prone to fluctuations, the decision tree will be updated as the season unfolds, so users should check it regularly,” urges Mr Ranner.
