title: Selection of a pesticide with low environmental impact.
abstract: The conditions were analyzed for evaluation of a mean soil biodegradation of a pesticide within a certain region. Different soils from two Czech and two German regions were used for a highly sensitive analysis based on a laboratory incubation of each isolated active soil strain with a radiolabeled pesticide. It was proved for all analyzed soils that the biodegradation activity of the total biomass was caused by only a small part of the present microbial strains. Not only bacteria, but also fungi and yeast have to be taken into consideration in a pesticide biodegradation. The biodegradation products were quantified by radio high-performance liquid chromatography.
