# Commission Regulation (EU) No 546/2011 of 10 June 2011 implementing Regulation (EC) No 1107/2009 of the European Parliament and of the Council as regards uniform principles for evaluation and authorisation of plant protection products (Text with EEA relevance), Division 2.2.1.3

Extent: E+W+S+N.I.

The mode of action of the micro-organism shall be evaluated in as much detail as appropriate. The possible role of metabolites/toxins for the mode of action shall be evaluated and when identified, the minimal effective concentration for each active metabolite/toxin shall be established. Information on mode of action can be a very valuable tool in identifying potential risks. Aspects to be considered in the evaluation, are:
(a)antibiosis;
(b)induction of plant resistance;
(c)interference with the virulence of a pathogenic target organism;
(d)endophytic growth;
(e)root colonisation;
(f)competition of ecological niche (e.g. nutrients, habitats);
(g)parasitisation;
(h)invertebrate pathogenicity.
