How was the summer of 2019, was it wet or dry? What diseases attacked the crops and how did the pesticides work? How about septoria in wheat? And what about diseases in potatoes and beets? Were there any problems with fungicide resistance in wheat? And how can you reduce drift by spraying in potatoes and strawberries? 

Answers to these questions and many more can be found in the 2019 issue of the report "Applied Crop Protection" published by DCA - National Center for Food and Agriculture. It is an annual report with results and advice to farmers, advisers, industry, and researchers on plant protection. 

This year's edition highlights, among other things:

  • Overview of the weather and trial season 2019 and achieved additional yields for spraying
  • Effects of new fungicides, including optimal dosing and timing
  • Results of various mitigation strategies, including testing of decision support systems for the fight against specific harm doers
  • Results regarding fungicide resistance
  • Results from monitoring for diseases in red fescue 
  • The order of resistance of the varieties to Fusarium and yellow leaf spot in wheat
  • Screening for new herbicides to control grasses within the bromes family
  • Opportunities for reducing drift by spraying in potatoes and strawberries
  • Testing of funds for less-grown crops

The report is based on the results of studies carried out in the Department of Agroecology regarding applied plant protection. The report summarises the data considered relevant for practical farming and consulting.

Most of the tests have been carried out in the field, but there are also results from studies in greenhouses and semifields.

Behind the report

Collaboration partners: Staff at Aarhus University (Department of Agroecology and DCA - National Center for Food and Agriculture) - Pesticides and counselling providers from SEGES and local counselling centers have been used in the experiments, but have not been involved in the preparation of the report.

Funding: The report is based on trials funded from many different sources. This is specifically stated for each chapter of the report. Input from the agrochemical companies, processing companies, the kartoffelafgiftsfonden, the sukkerroeafgiftsfonden, the frøafgiftsfonden, as well as direct funding from Aarhus University.

Conflicts of Interest: None
