| Abstract:
Sciarids (or ‘Fungus gnat’, Bradysia sp. Diptera: Sciaridae) are one of the most important pests in the organic production of potted herbs. Therefore, a method to easily monitor sciarids in pots was developed and different pest control agents were compared at FiBL CH in 2008. Our experiments showed that control with the nematode Steinernema feltiae was most successful, with an efficacy of 69–90% at 24°C air temperature. Azadirachtin (Neem-seed oil) could be an alternative under hot conditions (>28°C). Bacillus thuringiensis israelensis, however, showed only a minor effect (1-51% efficacy). | |
