Division 2.2.1.3 The mode of action of the micro-organism should be evaluated in as much detail as appropriate. The possible role of metabolites/toxins for the mode of action should be evaluated and when identified, the minimal effective concentration for each active metabolite/toxin should 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:
United Kingdom
- (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.
