Development of specific fundamentals for plant health measures and regulations against quarantine organisms
Project
Project code: JKI-AG-08-0002
Contract period: 01.01.2008

Purpose of research: Applied research
Plant health measures have to be technically justified to avoid barriers to trade as a result of unjustified requirements. Risk analyses play an important role here. For quarantine and new harmful organisms, there are as a rule no scientific data on specific aspects relevant to final risk analysis and the adoption of regulations. In particular, data on host plants of the harmful organisms, the ability to establish, pathways of introduction and spreading are lacking. In many cases it is not known fundamental knowledge of how to identify infections on import is lacking. This is especially true of latent infections (bacteria, viruses, viroids). Where possible, sensitive identification procedures have to be adjusted or the most suitable tests have to be found. Studies have to be carried out especially for the pathogen, the specific situation and to current problems of plant health.
Example: Studies on the pathways of the introduction of Clavibacter michiganensis ssp. sepedonicus (Cms) (causal agent of bacterial ring rot of potatoes) and on its persistence in soil and on various materials have shown that the causal agent can be easily transmitted through contaminated equipment and machines, mixing of healthy and infected tubers and through latently infected seed tubers. Detailed results on persistence in soil depending on soil type and temperature were obtained. The results played a decisive role in the specification of control measures and formed the basis of a national guideline on the control of Cms in Germany. The acceptance of the measures by the competent authorities and associations dealing with potato production could be considerably increased. The results had a great impact on the review of the EU control directive.
