Phytophthora – это грибоподобные организмы, относящиеся к оомицетам. Виды данного рода вызывают заболевания, приводящие к экономическим потерям и оказывающие экологическое воздействие в питомниках, лесах и природных экосистемах. Род включает много видов, которые вызывают корневые и прикорневые гнили, увядание, ожоги листьев и стеблей, язвы, и отмирание стеблей, что приводит к экономическим последствиям по всему миру. Некоторые виды являются особенно разрушительными фитопатогенами и поэтому включены в карантинные перечни различных стран. В статье представлен краткий обзор информации о карантинных видах рода Phytophthora, ассоциированных с древесными, кустарниковыми и декоративными растениями. Приведены виды данного рода, регулируемые в различных странах мира. Дано описание растенийхозяев и морфологических признаков для возбудителей фитофтороза декоративных и кустарниковых растений Phytophthora kernoviae Brasier, Beales & S.A. Kirk, Phytophthora ramorum Werres, De Cock & Man in't Veld и возбудителя фитофтороза ольхи Phytophthora alni Brasier & S.A. Kirk. Описано распространение данных патогенов в мире, а также их фитосанитарный статус и вредоносность. Приведены иллюстрации симптомов и основных морфологических диагностических признаков.

Phytophthora are fungi-like organisms belonging to the oomycetes. Species of this genus cause diseases that lead to economic losses and have ecological impacts in nurseries, forests, and natural ecosystems. The genus includes a lot of species that cause root and basal rots, wilting, leaf and stem blight, cankers, and stem dieback, leading to economic consequences worldwide. Some species are particularly harmful plant pathogens and are therefore included in quarantine lists of various countries. This article provides a brief overview of quarantine species of the genus Phytophthora associated with trees, shrubs, and ornamental plants. Species of this genus regulated in various countries are listed. It gives a description of the host plants and morphological characters of the pathogens that cause late blight of ornamental plants and shrubs – Phytophthora kernoviae Brasier, Beales & S.A. Kirk, Phytophthora ramorum Werres, De Cock & Man in't Veld, as well as Phytophthora alni Brasier & S.A. Kirk. The global distribution of these pathogens, as well as their phytosanitary status and harmfulness, is described. Illustrations of symptoms and key morphological diagnostic characters are provided.
