Assessment and testing of strawberry pathogens (SPAT)


Strawberry (Fragaria × ananassa) is an important food crop that is susceptible to a range of pests, including fungi, bacteria, viruses and nematodes. The main fugal pathogens in Europe are Phytophthora cactorum (crown rot), Colletotrichun acutatum, Verticillium dahliae, Botrytis cinerea (grey mould), Mycosphaerella fragariae (purple stain), and Sphaerotheca macularis, while the main bacterial disease is Xanthomonas fragariae (angular leaf spot). The objectives of the project were to make an overview of literature on strawberry diseases in partner countries and on all of the testing methods that are applicable in testing for X. fragariae and P. fragariae. Another objective was to develop and update diagnostic protocols and evaluate their strength and weaknesses by a ring test.
