Phytophthora inflata Caros & Tucker was detected together with P. citricola Sawada from rhododendron cv. University of Helsinki with necrotic spots on leaves. Spots were enlarged on tip parts of the stems. The rhododendron plantswere taken from hardy ornamental stock. Inoculation of the leaf blades of 15 species and cultivars of rhododendron with P. inflata and P. citricola resulted in the development of necroses on all of them. Reaction of tested rhododendron species and cultivars for P. inflata and P. citricola was similar. The pathogen also colonized leaf blades of Goultheria decumbens, Kalmia ostroseptice, Vaccinium corymbiferum and V. vitis-idaea. The quickest spread of necroses was observed on K. ostroseptice and V. corymbiferum. In greenhouse trials P. citricola and P. citrophthora caused dieback of more rhododendron plants than P. inflata.

Gatunek Phytophthora inflata wykryto razem z P. citricola na różaneczniku odmiany University of Helsinki z objawami plamistości liści, rozszerzającej się na wierzchołkowe części łodyg. Inokulacja liści 15 gatunków i odmian różaneczników izolatami P. inflata i P. citricola, spowodowała rozwój nekrotycznych plam na ich powierzchni. Reakcja testowanych gatunków i odmian różanecznika na oba gatunki była podobna. Gatunek P. inflata kolonizował również blaszki liściowe Goultheria decumbens, Kalmia ostroseptice, Vaccinium corymbiferum i V. vitis-idaea, przy czym nekrotyczne plamy rozwijały się najszybciej na V. corymbiferum. W doświadczeniu szklarniowym P. citricola i P. citrophthora powodowały zamieranie większej liczby roślin aniżeli P. inflata.
