Another infection site of a potato pest found in the Tomsk region
-----------------------------------------------------------------
Specialists of the Tomsk office of Rosselkhoznadzor [Federal Service for
Veterinary and Phytosanitary Surveillance] have identified a focus of
infection with golden potato nematode in one private garden. The total area
of the infestation near Mezheninovka is 0.09 hectares [0.2 acres].
 
A phytosanitary quarantine zone was imposed. In 2008, quarantine was
imposed on more than 10 regions of Tomsk where the nematode was found.

[Both golden (_Globodera rostochiensis_, with at least 5 races) and pale
(_G. pallida_) potato cyst nematodes (PCNs) cause serious crop losses in
potato. Other solanaceous crops (such as tomato) and weeds may serve as
pathogen reservoirs. Symptoms on potato include stunting, yellowing, and
wilting of leaves as well as a reduced root system. PCNs may lead to
complete crop failure. Diseased plants first occur in isolated patches and
these become larger with each new crop.
 
The nematodes can survive in soil for up to 20 years as cysts. Spread
occurs via infected soil, water, wind, or on plant material. Disease
management includes exclusion, long crop rotation with non-host species,
use of crop cultivars resistant to specific PCN races, and nematicides.
These control measures can be combined to keep nematode levels below
economic thresholds. Both PCNs have been included on the alert list of the
European Plant Protection Organisation (EPPO).
 
While pale PCN has never been reported from Russia and its immediate
neighbours, golden PCN is widely distributed in the Eurasian area. In
Russia, golden PCN was reported in 2009 from the neighbouring Novosibirsk
(ProMED-mail post 20091109.3882), Krasnoyarsk, and Khakasia (ProMED-mail
post 20091005.3458), and this region of eastern Siberia appears to be
considerably affected by golden PCN. Previous PCN reports from other more
widely spread out Russian areas were also considered likely to be golden PCN.
