project will determine the risks posed to EU wheat by the fungal
plant pathogen, Tilletia indica, the cause of Karnal bunt
in wheat. T .indica has not been recorded in Europe but
has been intercepted on wheat imports. Legislation to protect
EU wheat was enforced by the EC in 1997 based on a theoretical
pest risk analysis (PRA) which concluded that the pathogen had
the potential to establish in Europe and cause reductions in wheat
quality, yield and to damage export markets. International debate
has questioned the justification for legislation, implying such
policies are trade-restrictive. Research will be undertaken to
develop a more accurate PRA for T. indica. Crop and pathogen
modelling and geographical information systems will determine
areas at risk. A socio-economic model will determine the risks
this and related pathogens pose. A PRA based on scientific experimentation
will be produced which can be used internationally by policy-makers
to re-evaluate legislation for T. indica. A risk management
plan will be developed for Europe. The international PRA process
will be developed for plant pathogens.
To accurately predict the risk of Tilletia indica becoming
established in Europe by combining crop and pathogen models and
to use these alongside new pathogen data in pest risk mapping
and pest risk analysis to support and underpin EU plant health
policy and legislation on T. indica.
2. To determine the susceptibility of European wheat cultivars
to T. indica and to estimate potential losses of yield
of these cultivars if T. indica reaches Europe.
3. To determine the survival of T. indica teliospores under
a range of European soil conditions.
4. To determine the abiotic factors that affect dormancy and germination
of T. indica teliospores using controlled environments,
relating the results to European climatic conditions and European
wheat crop phenology.
5. To accurately predict the likely socio-economic impact of T.
indica should it be introduced into Europe.
6. To analyse the risk of entry, establishment and socio-economic
losses for the EU and to develop harmonised risk-management strategies
and contingency plans to deal with actual introductions of T.
indica to Europe, especially aspects of eradication, containment
and control, whilst minimising disruption to free trade.
7. To generalise the specific findings of the project so as to
develop risk analysis techniques for other plant pathogens of
potential threat to the EU, supporting EU and international plant
health policy and legislation.
8. To disseminate project outputs on (a) The risks to the EU from
Tilletia indica and (b) Advances in pest risk analysis
for plant pathogens.This will specifically be achieved through
an internet website established for the project and by holding
a workshop at the end of the project for representatives from
EU Member States, accession countries and other interested parties
(including representatives from national and/or international
plant health organisations).
