ABSTRACT
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
