Field slug

The field slug (Deroceras reticulatum) is a common mollusk belonging to the family Limacidae. It is considered a significant agricultural pest, particularly in humid environments, where it can rapidly proliferate and cause substantial damage to a wide variety of cultivated crops.

Slugs are highly polyphagous pests. They feed on a broad spectrum of plants, including vegetables such as lettuce, cabbages, potatoes, and strawberries, as well as field crops like winter cereals. They are particularly attracted to succulent tissues and seedlings, which can be devastated during early stages of growth.

Regarding their biology and lifecycle, slugs thrive in environments with moisture and shade. They spend their days inactive under soil debris, rocks, or dense vegetation. Their reproduction is prolific, with eggs deposited in clusters within damp soil. Depending on ambient temperatures, they can complete multiple life cycles within a single growing season.

The damage caused by these pests is characterized by irregular holes in leaves and deep, hollowing bites in fruits and tubers. Beyond the loss of biomass, the presence of slimy trails and excrement lowers the aesthetic quality and shelf life of the harvest. The wounds created by slugs often serve as entry points for plant pathogens.

• Implement good sanitation by removing hiding spots such as boards or weeds.
• Use physical barriers like copper tape or abrasive mulch around vulnerable crops.
• Install slug traps to monitor and reduce populations manually.
• Apply iron phosphate-based baits, which are safer for the environment.
• Encourage local predator populations such as ground beetles, frogs, and hedgehogs.
