Nematodes or roundworms are used as natural enemies of insect larvae. These natural enemies live in the soil and use their prey as a food source and breeding ground. The nematodes penetrate the prey and secrete bacteria, causing the prey to die within two to three days.

Use of nematodes in horticulture

When you want to buy nematodes or roundworms and use them as biological fighters, it is important to distinguish between two different types of nematodes: Nemaslug and Nemasys. Nemaslug are beneficial nematodes that are used against house and slugs while Nemasys is suitable for insect larvae. Moreover, Nemasys is available in different variants: Nemasys L (Steinernema kraussei), Nemasys F (Steinernema feltiae) and Nemasys H (Heterorhabditis bacteriophora). Biological control with the aid of nematodes fits perfectly into integrated crop protection.

Conditions of application for nematodes

Roundworms perform best in a moist soil with a temperature between 5 and 30°C. Take these conditions into account when using nematodes or roundworms in your crop. Biological control with beneficial nematodes is completely safe for humans, the environment, the crop and other natural enemies. 

Administering nematodes with spraying equipment

Nematodes are administered with the usual spraying equipment and water. Fill the spray vessel or spray tank for three quarters with water. Meanwhile, prepare the nematode solution; fill a bucket with 10L of water and add the entire package of nematodes. Stir the solution well. Then fill the vessel or tank with the required amount of water. Apply the spray liquid immediately after mixing, this will prevent the nematodes from sinking.
