[A comparative evaluation of acute action thresholds during the isolated and combined effects of boricid fungicide and its components (polycarbacin+sulphur)].

The article contains a comparative analysis of the acute action thresholds in isolated and combined actions of boricide fungicide and its components when inhaled. To determine the predominant type of the combined action, a correlation analysis technique of dosage (concentration) dependences was used with regard both to mixtures and isolated components, as it was done in case with the lethality curves studies involving calculation of the combined action coefficient. The coefficient calculation technique used for the lethality levels can be adequately applied to the calculations of acute action thresholds of a permanent composition mixture by CE50 degrees and CE50 min.
