From Hedera helix and Epipremnum aureum showing necrosis of shoot base spread upwards and on leaves Phytophthora tropicalis was isolated. The species was obtained from ⅞ of Hedera and ¾ of Epipremnum diseased shoot and root parts. Additionally, Botrytis cinerea, Fusarium avenaceum and Rhizoctonia solani was recovered from some of affected plants. The chosen 2 isolates colonised petioles and leaf blades of both host plants. P. tropicalis caused necrosis of leaves of 11 tested cultivars of H. helix and 13 other pot plant species and seedlings of tomato. The fastest spread of necrosis was observed on leaves of Peperomia magnoliaefolia, Pelargonium zonale and Phalaenopsis x hybridum. The development of disease was observed at temperatures ranged from 10 to 32.5°C with optimum 30°C.

PL

Z Hedera helix i Epipremnum aureum, z objawami zgnilizny podstawy pędów, rozszerzającej się ku górze i na blaszki liściowe oraz zgnilizną korzeni, izolowano Phytophthora tropicalis. Gatunek ten stwierdzono na 7/8 analizowanych roślin H. helix i 3/4 E. aureum. Ponadto z porażonych tkanek niektórych roślin wyizolowano Botrytis cinerea, Fusarium avenaceum i Rhizoctonia solani. Wybrane dwa izolaty P. tropicalis kolonizowały liście obu roślin – gospodarzy. Omawiany gatunek powodował nekrozę liści 11 odmian H. helix, 15 gatunków roślin doniczkowych oraz siewek pomidorów. Najszybszy rozwój nekrozy obserwowano na liściach Peperomia magnoliaefolia, Pelargonium zonale i Phalaenopsis x hybridum. Rozwój choroby obserwowano w temperaturze od 10–32,5°C przy optimum 30°C.
