Two risk models have been tested for their validity.In a collaboration with different Nordic and Baltic partners two risk models have been tested for their validity.
Septoria is a fungus that can cause great damage in wheat fields and in severe cases can cause great yield losses. Therefore, it is important that the farmer has a clear strategy for how to control septoria in his fields. Usually this is done by spraying the field with fungicides; in Denmark, winter wheat is usually sprayed 2-3 times per season, i.e. to fight septoria caused by the fungus Zymoseptoria tritici. Validations have shown that the number of sprays can be reduced if risk models are used to determine control needs.
The results of the validation experiments have just been accepted for publication in "European Journal of Plant Pathology: "Validation of risk models for control of leaf blotch diseases in wheat in the Nordic and Baltic countries."
