Key messages

• Insecticide management with the Imidacloprid seed treatment Gaucho significantly increased yield by 0.56 t/ha but additional foliar insecticides applied at tillering and at GS31 gave no further yield increases over Gaucho seed treatment alone.
• Adding additional fungicides (prochloraz and azoxystrobin) to the stem base GS31 fungicide based on epoxicionazole (Opus) significantly increased yield.
