Three species of powdery mildew (Erysiphales) on eggplant ( L.) have been
listed in Korea, namely (now genus Golovinomyces), Leveillula taurica,
and (now genus Podosphaera; syn. ). Since E.
cichoracearum was recorded on eggplant for the first time in Korea in 1969, it has been regarded
as a major powdery mildew agent on that plant. In 1998, the causal agent of powdery mildew on
eggplant was recorded as then as in 2002. During our extensive field surveys
in Korea, we collected 22 samples of eggplant powdery mildews. Our microscopic observations
and molecular sequence analyses showed that all of our samples belonged to the genus
Podosphaera, in the absence of either or suggesting that P. xanthii
is the dominant agent of powdery mildew disease on eggplants in Korea. As there have been no
additional findings on L. taurica after the first report on the species, it seems to be a minor species
that is rarely found in greenhouses. The presence of (syn. Golovinomyces
cichoracearum s. lat.) on eggplants is questionable, as the morphological characteristics of E.
cichoracearum in the original description of the Korean collection deviate from the morphological
variations of this species. In addition, no herbarium material of remains.
Consequently, it seems that P. xanthii is the main species of powdery mildew on eggplants,
whereas L. taurica occurs rarely on eggplants, in Korea. This review provides the historical and
recent taxonomy of eggplant powdery mildews in detail.
