EFFICIENCY OF ORGANOTIN DITHIOCARBAMATE DERIVATIVES AGAINST WOOD DESTROYING FUNGI

The efficiency of several new groups of organotin compounds (dibutylti n dithiocarbamates, tributyltin dithiocarbamates and tributyltin dithi ocarbamate propionates) against wood destroying fungi (Serpula lacryma ns, Coniophora puteana, Coriolus versicolor) was tested. The best resu lts were obtained from tributyltin dithiocarbamates, especially from t ributyltin N-pyrolidine dithiocarbamate and tributyltin N,N-dialkyldit hiocarbamate propionate. The total efficiency of these compounds was n early the same as that of the commercially available products TBTN and TBTA. For the brown-rot fungus C. puteana tributyltin N-pyrolidine di thiocarbamate and tributyltin N-piperidine dithiocarbamate compounds w ere more effective than the standard commercial product TBTA even at t he concentration of 0.0001%. The efficiency of dibutyltin dithiocarbam ates was low both in comparison with the commercial standards and with tributyltin substituted compounds.
