nemaplus® depot
PREVENTIVE CONTROL OF SCIARIDS IN GREENHOUSES
nemaplus® depot contains beneficial nematodes of the species Steinernema feltiae embedded in alginate capsules for preventive and long term control of fungus gnat larvae (Bradysia spp., Lycoriella spp.) in the substrate.
| Active ingredient | Steinernema feltiae |
| Formulation | Alginate capsules |
| Package sizes | 25 mio. |
| Shelf life | 6 weeks |
| Listings | FiBL |
APPLICATION OF NEMAPLUS® DEPOT
Mix the capsules evenly into the substrate or insert them into the planting hole when sowing, sticking or potting. All organic substrates are suitable; sterilized substrates containing almost no micro-organisms are not suitable. Cover the capsules with at least 2 cm of substrate.
Commercially available fertilizer spreaders are suitable for machine application. The substrate should remain moist during application. If the capsules cannot be incorporated into the growing media, ensure high humidity or cover them with a fleece.
nemaplus® depot is effective for at least 6 weeks, with the greatest effectiveness recorded during the 2nd to 4th week after application. It is ideal for preventive treatment at the start of cultivation.
Dosage
- Mixing into the substrate: 12 capsules per litre of growing media or 50 million over 2,5m3
- Incporporation during sowing / sticking / potting: 6-7 capsules per litre filling volume
MODE OF ACTION
One nemaplus® depot capsule contains approx. 2,000 nematodes in a water-oil emulsion enclosed in an alginate shell. Upon contact with the soil/ substrate, the alginate shell becomes permeable within a week and the nematodes migrate. Over several weeks, new nematodes enter the substrate and look for sciarid fly larvae in the soil to use as their host. Once a larvae is found the nematodes invade through natural openings into the body cavity, where they release their symbiotic bacteria. The bacteria multiply and kill the insect within 1-2 days. The nematodes feed on the bacteria and propagate. About 1,000 nematodes of the next generation emerge two weeks after application from one sciarid larva.
nemaplus® depot is safe for beneficial insects, plants and humans.

ADVANTAGES OF NEMAPLUS® DEPOT
in contrast to powdered products, where the nematodes are applied with the irrigation water and immediately enter the substrate, the nematodes leave the capsules with a time delay. If the capsules are introduced into the substrate, the shell becomes permeable after about a week and the nematodes gradually migrate out. This slow release process results in twice the duration of action compared to standard application.
