Latin name: Limax spp., Arion spp., Deroceras spp.

Description:

Slugs can be a major problem during harvest when they feed on berries causing loss of quality. Damage is accompanied by slime trails, which can also render fruit unmarketable. They can also be a harvest contaminant. The slug population is closely correlated to weather conditions during harvest. Cool, wet conditions can lead to major slug problems.

Scouting:

  • Check for slime trails and slugs well before harvest to determine their potential as a harvest pest.
  • Small bait stations of slug bait can be put out in the field marked by flags. Check periodically for slug activity.
  • If the weather forecast favors slug activity, scout more often.
  • Slug bait cannot be applied when fruit is close to harvest since t can stick to the fruit and be a contaminant. Appropriate controls should be applied to even lightly infested fields to prevent a problem during harvest.

 
Cultural Controls:

  • Eliminate slug habitat and hiding places.

 

For information about chemical controls, check with our Pesticide Guide.
