Preface

Sensor-based graduation of fungicide application in winter wheat

The project has been conducted in collaboration between University of Aarhus, Faculty of Agricultural Sciences (DJF) and the Danish Agricultural Advisory Service (DAAS). The basic experimental treatments and the yield determination were performed by DAAS, whereas all disease assessments, measurements of fungicide deposition and sensor measurements were conducted by DJF, who also was responsible for the model development.

The project leader was Jørgen E. Olesen (DJF), and the following researchers from DIAS contributed to the different research topics: Lise Nistrup Jørgensen, Peter Kryger Jensen and Anton G. Thomsen. The following advisors from DAAS were involved in designing and conducting the field experiments. Jens Erik Jensen, Bo J.M. Secher and Hanne Schønning. Ole Møller Hansen from DAAS was involved in the planing process. The following technicians from DIAS and DAAS contributed to the project: Finn Christensen, Uffe Pilegård Larsen, Carsten Sparholt, Søren H. Sørensen and Henning Nissen.

The project was funded under the crop protection research programme of the Danish Environment Agency. Additional funding was provided from "Gluds Legat" for a more detailed analysis of the laser sensors measurements in the project.

The input of the scientific sparring group under the crop protection research programme is gratefully acknowledged. This sparring group had the following members: Tommy Dalgaard, Peter Esbjerg, Lene Gravesen, Mette Jensen, Pernille Kaltoft, Jørn Kirkegaard, Kristian Kristensen, Niels Lindemark, Peter Odderskær, Hanne L.
