Climate change and plant health - increasing importance of biocontrol optionsfor risk management of quarantine pests


Abstract: Plant health is directly or indirectly influenced by climatic factors. The potentialeffects of climate change together with the increasing globalisation of trade with plants and plantproducts will facilitate the introduction, natural invasion and spread of non-endemic phytosanitaryplant pathogen species of economic importance to previously unaffected agricultural,horticultural or forestry production areas. Whereas the introduction of quarantine pests can partlybe prevented by inspections and monitoring surveys, risk management strategies in case of theirestablishment and spread under changed climatic conditions are mainly missing. In this contextfuture research needs on climate change effects on plant pathogens and biological control whichhave been identified are presented and discussed.
