First record of Globodera pallida in Ukraine
In Ukraine, Globodera rostochiensis (EPPO A2 list) was first identified in 1963 in the Western part of the country, in the province (oblast) of Chernivtsi, in the fields of a Research Station. Despite phytosanitary measures, G. rostochiensis spread to other potato-growing regions. At present, G. rostochiensis is recorded in the following 13 provinces, infesting approximately 5500 ha: Cherkasy (181.5 ha), Chernihiv (1323.7 ha), Ivano-Frankivs’k (5.7 ha), Khmel’nyts’kyi (34.6 ha), Kiev (61.5 ha), Lviv (896 ha), Rivne (638.3 ha), Sumy (780.22 ha), Ternopil (22.5 ha), Vinnytsia (17.7 ha), Luts’k (Volyns’ka oblast) (1173.3 ha), Uzhhorod (Zakarpats’ka oblast) (21.3 ha), Zhytomyr (372.6 ha).
A survey using molecular techniques (Multiplex PCR) was conducted in these 13 Ukrainian provinces. Results revealed the occurrence of Globodera pallida in the region of Uzhhorod (Zakarpats’ka oblast). This is the first report of G. pallida in Ukraine. G. pallida was found in mixed populations with G. rostochiensis but was less prevalent. The origin of the introduction of G. pallida into Ukraine is unknown. Phyllogenetic studies showed that the Ukrainian population was very closely related to other G. pallida pa2/3 isolates found in Europe.
The situation of G. rostochiensis in Ukraine can be described as follows: Present, first found in 1963; occurring in 13 provinces (approximately 5500 ha), under official control.
The situation of G. pallida in Ukraine can be described as follows: Present, first reported in 2005 near Uzhhorod (Zakarpats’ka Oblast), under official control.
