ABSTRACT

In laboratory experiment the influence of different dosages of fungicides on the activity of acid and alkaline phosphatase, dehydrogenase, urease, b-glucosidase and ATP content in loamy clay soil was determined. The fungicides were applied alone and with additions of an adiuvants applied at field rate and 10-fold and 100-fold higher. The following combinations were used: Miedzian 50 WP (a.i. copper oxychloride), Miedzian 350 extra SC (Miedzian 50 WP + Polybutene emulsion) and Miedzian 50 WP applied together with Rapol 90 EC. The soil sample was submitted to analysis in 1, 3, 7, 14, 28, 56 and 112 days after the pesticides treatment. The investigations showed that soil enzymes activity after use pesticides with adiuvants was lower from activities these enzymes in soil after use of fungicides without adiuvants, it was especially visible in case of dehydrogenase and b-glucosidase. Also ATP content in soil with addition all of three

Key words: fungicide, adjuvant, enzymatic activity, ATP, soil.
