The experiment is a continuation of studies on the effect of mixing order of selected fungicides and zoocides on physico-chemical properties of spray liquids. In the experiment a total of 7 fungicides were tested (Aliette 80 WP, Amistar 250 SC, Discus 500 WG, Folicur BT 225 EC, Mirage 450 EC, Nimrod 250 EC, Proplant 722 SC) as well as 7 zoocides (Admiral 100 EC, Aztec 140 EW, Confidor 200 SL, Marshal 250 CS, Mospilan 20 SP, Nissorun 050 EC, Talstar 100 EC), which were mixed in the recommended order and in the reverse order to the recommended one. Phytoxicity was assessed on the basis of the determined effect of tank mixtures on weight of white mustard seedlings, the evaluation of burn degree and weight loss.
