Fungicide use in wheat can be reduced

The use of fungicide in wheat can be considerably reduced when using resistant wheat varieties, according to scientists from Aarhus University and other European research institutes.

It is possible to reduce the use of fungicides when growing winter wheat without imparing yields. The secret is to use fungicide-resistant wheat varieties. A closer description of this topic can be found in a new leaflet produced by European scientists, who all participate in the large EU-project ENDURE.

The group includes scientists from the Faculty of Agricultural Sciences at Aarhus University. The advantages of growing resistant varieties are considerable and an important parameter in an integrated plant protection strategy. In a single season the number of fungicide treatments can be reduced by one or two treatments and the dosage can be reduced by 25-50%, depending on the climate and the level of resistance of the wheat variety used.

The average saving when using resistant wheat varieties works out at €20 per hectare according to French investigations. The farmer also has much more flexibility in the timing and rate of application when choosing resistant varieties.

Before the scientists produced the leaflet, they took stock of existing knowledge and research on fungi and fungicides in wheat in Europe. The leaflet sets out the optimal control strategies in both resistant and susceptible wheat varieties at low and high cereal prices.

The leaflet can be downloaded from the ENDURE website.
