[Effects produced by insecticides on micro-organisms growing on harvest crops (vegetable foodstuff) (author's transl)].

Micro-organisms were isolated from several harvest crops and identified. Their capacity of breaking down pesticides frequently applied over large areas was investigated. It was found that some types of molds regularly found on untreated foodstuffs of vegetable origin have changed in composition and germ density during the last 5 to 10 years and that they are capable of more or less breaking down pesticides only to a limited extent. The particularly great increase of F. oxysporum in maize (corn) and corn flour can, accordingly, be caused by the application of herbicides.
