title: [Mutagenic action of synthetic fungicides and drugs of biological origin on microorganisms].
abstract: Gene-toxical effect of biological and synthetical fungicides on auxotrophic test-cultures of Salmonella typhimuriun TA 100 and TA 98, and Escherichia coli WP2 has been studied. Biological drugs on the basis of hytosan (mycosan and mycosan-new) act as weak mutagens. Synthetical fungicides on the basis of benomil and tiram, on the contrary, cause higher frequency of mutation. The exceeding of the recommended doses of these drugs significantly increases gene-toxical loading. This evidences for a necessity to revise agrotechnologies in the direction of decrease of the existing standard.
