Pesticide resistance

Pesticide resistance is a challenge for agriculture in certain crops, where there is development of resistance in both weeds, fungal diseases and pests. This together with the small amount of new active substances and control methods constitutes an increasing global problem. Occurrence of resistance in weeds, insects and plant pathogens is seen more frequently in the field because the usual measures no longer are sufficient. Pests develop pesticide resistance through natural selection; the most resistant individuals survive and transfer their genetic properties to their offspring.  

The goal of the research is to develop and introduce resistance strategies that ensure a targeted and limited use of pesticides by maintaining sensitivity to pesticides in pest populations. The use of IPM - integrated plant protection is an essential element of this strategy. From an evolutionary ecological point of view, we investigate the principles of a pest adaptation to different control systems, which include development of new tools and strategies that can identify and alleviate resistance problems. The research is primarily done with molecular biological methods focusing on the origin, frequency and biological significance of resistance genes.
