An infected slug stops feeding within 3 to 5 days and then displays a typical swelling of the mantle. The nematodes multiply inside the slug and when it starts to decompose, a new generation of nematodes spreads and starts looking for the next prey
The nematodes can be used applied between May and September. In order to protect young seedlings or cuttings against slugs, it is best to apply the nematodes 1 week in advance of planting. Ensure the soil is moist before applying the nematodes and kept moist for two weeks.
The nematodes provide protection against slugs for approximately 6 weeks.
Biological Control
Slug Nematodes
Slug nematodes are microscopically small worms that are capable of effectively parasitizing and killing slugs.
The nematodes are applied as a drench to the soil surface. They actively search for their prey and invade it via the respiratory opening under the mantle.
