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 phosphate bait-Slower activity than metaldehyde baits, and application rate is three to four times higher than that of metaldehyde.
- metaldehyde bait-Broadcast to seedbed around borders and between rows. Do not apply directly to plants. Use this product with caution, as it is toxic to pets.
- sodium ferric EDTA
