Unexpected viral incidence in Phytophthora cactorum infecting strawberry

Phytophthora cactorum is a pathogenic Oomycete that can infect a wide variety of plant species, among them strawberry, where it can cause strawberry crown rot and strawberry leather rot of fruits. Both diseases cause economic losses in strawberry production and are controlled mainly by selecting healthy plants for planting and by planting strawberries on ridges to improve drainage and aeration, but also sanitation and fungicides are used.
Viruses infecting Phytophthora species have been discovered relatively recently and up to 2020 only a few have been described. In the frame of Viroplant project, the virus community of P. cactorum infecting strawberry plants in Finland was extensively studied, in order to assess abundance, genetic variability as well as spatial and temporal occurrence. Results showed that the incidence of viruses in strawberry isolates of P. cactorum was unexpectedly high, nearly 100%.
