Plant Protection Centres

The aim of the Plant Protection Centers is to make plant protection in agri- and horticulture both efficient and environment friendly. The centres are located in five different places in Sweden.


The objectives are
  • to achieve optimal integration of the cultivation system and technique with the factors of production while taking environmental concerns into account;
  • to adapt the use of pesticides to need;
  • to help avoid health and environmental hazards in pesticide use; and
  • to obtain a more biodiverse fauna and flora.

What the Plant Protection Centres do

Pest and disease prognoses

The presence of pests, and the need for pesticides, vary much from year to year, and also from field to field in one year. To adapt the use of pesticides according to actual need is therefore very useful both for society's environmental concerns and for the individual farmer's financial situation.

The prognosis and early warning service is an important help for those farmers who wish to adapt their pesticide use to need. For certain pests, prognoses are made that in advance state an expected development. Such prognoses are made regularly for instance for birdcherry aphids, frit flies and eyespot in cereals and sclerotinia disease in spring oilseeds. Prognoses are made also as regards horticulture, for instance for dart moths, carrot flies and apple scab.

Early warning of pests and diseases

For most pests, there is as yet no method of prognosis. For such pests, information on the current situation (early warning) is given based on regular field observations and assessments of pests and diseases. During the growing season, plant protection data is gathered from approximately 1100 fields per week. After processing and analysis of this data, appropriate measures are discussed in the weekly telephone conferences led by the Plant Protection Centres. Participating in those conferences are local advisors as well as market representatives.


In order to correctly adapt pesticide use to need, the right diagnosis must first be made. It often takes special skills and equipment to determine the cause of damage. Every year, the Plant Protection Centres receive a large number of samples from the advisory service and market agents.


There is a great need for information concerning the use of pesticides, and the risks associated with this use. The Plant Protection Centres take active part in a large number of courses, field excursions, telephone meetings, and national and international conferences.

The centres also provide advisory and study material, and take part in studies on environmental, weed, and plant protection issues. Furthermore, most of the Plant Protection Centres' information is published on the Internet.


The Swedish University of Agricultural Sciences (SLU) is responsible for i.a. research and development in the field of environmental and plant protection. This includes among other things development of methods of pest prognosis. The SLU works in close co-operation with the Plant Protection Centres, whose role is primarily to evaluate and spread the methods of prognosis.

Methods of prognosis currently being developed are for example a long term prognosis for aphids by the use of suction traps, risk assessment for winter wheat moulds and a dosage key for weed control.
