Preventive control of sciarid larvae with beneficial nematodes.


Biological innovation in plant protection.

Flies of the Sciaridae family inflict the most damage on crops and are very common in greenhouses. In a dedicated cooperation, the German companies e-nema and Katz Biotech have developed nemaplus®depot. Encapsulated nematodes with a long-term and thus preventive effect protect your plants against sciarid larvae infestation even before any damage occurs.
