FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. The method involves mixing a preparation with water, placing oligochaetes into the obtained solution, holding for 30 minutes with subsequent determination of activity of the preparation from the behavioural reaction of oligochaetes. Activity of the preparation is indicated by oligochaetes not coiling in the presence of an active preparation.
EFFECT: efficient method of biotesting activity of a preparation derived from earthworms using oligochaetes.
