Abstract
This chapter provides a brief introduction on modern strawberry, a domesticated species for production, and on the economic importance of world strawberry production. It then discusses pathogen incidence in strawberry production, focusing on the main fungal pathogens, namely Botrytis cinerea, Colletotrichum spp., Fusarium oxysporum, Phytophthora spp., Verticillium spp. and other genera. Some diagnosis methods and field monitoring techniques of strawberry diseases are described, including molecular methods applied to phytopathogenic fungi, the past and present diagnosis methods, PCR alternatives applied to fungal diagnosis and other molecular techniques used to study fungal pathogens. The web-based decision support systems are also discussed. Some insights on proteomics advances in strawberry fungal pathogens are also given.
