Aus der "Wissenschaft":
More recently, a synergistic enhancement
of thiacloprid toxicity was found for combinations with azole fungicides in
laboratory toxicity tests. In response to this observation, tunnel studies were conducted to examine whether or not the observed synergism will impact honeybees under field conditions. In these tunnel tests, no increased mortality was observed when honeybees were directly sprayed with a combination of thiacloprid and tebuconazole, an azole fungicide. On the treatment day, a reduced foraging activity was observed in the treated crop but this effect disappeared within 48 hr (Schmuck and Schmidt, submitted).
Zum Glück weiss jeder Imker dass wären der Rapstracht die Sammelbienen 1 Tag arbeiten und dann 2 Tage Pause machen um sich von der Tankmischung zu erhohlen!!!
