Chemical stability of chlorine dioxide in the presence of prochloraz manganese

摘要

The chemical stability of chlorine dioxide (ClOsub2/sub) in the presence of prochloraz manganese (prochloraz-Mn) as biologically active substances used in agrochemical treatments in the cultivation of mushrooms are presented. For model mixtures of the tested components, a relative decrease in ClOsub2/sub content over time was measured in the proportions applied during the mushroom cultivation cycle. Within 20 min after preparing a mixture of 1 500 ppm prochloraz-Mn and 100 ppm ClOsub2/sub in water, the relative decrease in the concentration of ClOsub2/sub was 20%. The obtained results indicate a possibility of simultaneously introducing the working mixture of ClOsub2/sub and prochloraz-Mn salt into the champignon peat casing, assuming its use directly after preparation.
