Slug Feeding

scouted May 2, 2023

Soybeans were scouted at the VC (cotyledon) growth stage and there was feeding on the emerging leaves. This soybean crop is in a strip-till system, planted into a terminated small grain cover crop.
Slug feeding was confirmed by a NC State Extension Specialist. Insecticidal seed treatments have been shown to increase problems from slugs because they kill beneficial insects, such as ground beetles, that prey on slugs. Therefore, insecticides should be avoided at all costs when slugs are an issue. Best management practices for slugs include tillage, removal of residue at planting (e.g., row cleaners and strip tillage), and ensuring that the furrow closes completely when planting. Waiting for weather to turn hot and dry is often the best slug management tactic.
