First report of causing postharvest fruit rot on apples and pears in the Netherlands.

Apple () and pear () are important fruit crops in the Netherlands, with total production of 269,000 tons and 402,000 tons in 2018, respectively. In 2018 and 2019 postharvest fruit rots were observed on the apple variety Elstar (one observation) and pear varieties Conference and Doyenné du Comice (multiple observations). The symptoms were found after storage in controlled atmosphere storage facilities on fruits from different orchards across the Netherlands.

Copper treatment during storage reduces Phytophthora and Halophytophthora infection of Zostera marina seeds used for restoration.

Restoration is increasingly considered an essential tool to halt and reverse the rapid decline of vital coastal ecosystems dominated by habitat-forming foundation species such as seagrasses. However, two recently discovered pathogens of marine plants, Phytophthora gemini and Halophytophthora sp. Zostera, can seriously hamper restoration efforts by dramatically reducing seed germination.

Marine Phytophthora species can hamper conservation and restoration of vegetated coastal ecosystems.

Phytophthora species are potent pathogens that can devastate terrestrial plants, causing billions of dollars of damage yearly to agricultural crops and harming fragile ecosystems worldwide. Yet, virtually nothing is known about the distribution and pathogenicity of their marine relatives. This is surprising, as marine plants form vital habitats in coastal zones worldwide (i.

Phytophthora terminalis sp. nov. and Phytophthora occultans sp. nov., two invasive pathogens of ornamental plants in Europe.

In the past decade several Phytophthora strains were isolated from diseased Pachysandra terminalis plants suffering stem base and root rot, originating from the Netherlands and Belgium. All isolates were homothallic and had a felt-like colony pattern, produced semi-papillate sporangia, globose oogonia and had a maximum growth at ~ 27 C. Several additional Phytophthora strains were isolated from diseased Buxus sempervirens plants, originating from the Netherlands and Belgium, which had sustained stem base and root rot; similar strains also were isolated from Acer palmatum, Choisya ternata and Taxus in the United Kingdom.
