Summary

In einem ökologischen Feldversuch wurden die indirekten Auswirkungen einer gezielte Düngung sowie die direkte Behandlung des Rapsglanzkäfers mit Gesteinsmehl und Öl untersucht. Als entscheidenden Parameter wurde die Anzahl der Rapsglanzkäfer/Pflanze erfasst und Wirkungsgrade berechent.

Summary translation

Through missing pollen beetles (Brassicogethes aeneus) regulation, there is no yield stability in organic farming. In 2018 we studied the relationships between a complex fertilisation of organic grown radis (Raphanus sativus) for seedproduction with directly pest managements through Diabas stone flour near Bamberg, Germany. In a splitplot design at field was given fertilisation due to the results of a soil analysis. Through leave treatments after analysis we were able to controll the nutrient ingredient of plants in deficiency range. When pollen beetle appear in BBCH 51, there was a dusting of stone flour or a combination from sprayed rape oil in form of Micula® and dusting stone flour. Statistical calculation was done by JMP. We counted the pollen beetles per plant during the treatment and calculated the efficiency of treatments. Our results didn´t show confident effects. There was no correlation found between soil fertilisation and pollen beetles. By combining oil and stone flour, we have seen reduction of beetles after three days. The dryness in spring and summer of the year 2018 could be the reason for missing results of fertilisation.
