Pest description, crop damage and life history


Management-biological, cultural, tactical


Management-chemical control: HOME USE

Baits are the only registered chemical controls. These must be placed where slugs will encounter them in order to be effective. Baits are required year-round in moist, irrigated areas, but are most effective if placed after fall rains in dry conditions. Rain quickly degrades baits, so reapplication will be required. Cereal-based mini-pellets perform best in the PNW.

  • iron (ferric) phosphate bait-Slower activity than metaldehyde baits, and application rate is three to four times higher than that of metaldehyde. Some formulations are OMRI-listed for organic use.
  • sodium ferric EDTA

Management-chemical control: COMMERCIAL USE

  • iron phosphate (Sluggo Snail and Slug Bait) at 0.24 to 0.44 lb ai/A (24 to 44 lb/A). Consult label for REI and PHI.
  • metaldehyde baits. Do not contaminate edible plant parts. Use as needed but not more than once per week.
