Vergleich verschiedener direkten Regulierungsmöglichkeiten der Trauermücken in der biologischen Topfkräuterproduktion

Summary in the original language of the document

Sciarid flies (or fungus gnat, Bradysia sp.) are the most important pests in organic
production of potted herbs. Our experiments show, that control with the nematode
Steinernema feltiae is most successful, with an efficacy of 69-90 % at 24 °C air
temperature. Azadirachtin (Neem-seed oil) could be an alternative under hot condition
(> 28 °C). Bacillus thuringiensis israelensis, however, showed only a minor effect (1-
54 % efficacy).
