Chemical stability of chlorine dioxide in the presence of prochloraz manganese

Abstract

The chemical stability of chlorine dioxide (ClO<sub>2</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 ClO<sub>2</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 ClO<sub>2</sub> in water, the relative decrease in the concentration of ClO<sub>2</sub> was 20%. The obtained results indicate a possibility of simultaneously introducing the working mixture of ClO<sub>2</sub> and prochloraz-Mn salt into the champignon peat casing, assuming its use directly after preparation.
