Slugs of Lathyrus

Disease Information

Slugs

Symptoms

Damage similar to caterpillars`; these pests are nocturnal and can be found feeding at night.

Management

Rose slugs can be controlled by handpicking. They can also be removed by spraying with water. Once dislodged, they cannot climb back onto the plant. Insecticidal soap and horticultural oil are also effective against rose slugs. Other insecticidal sprays that are labeled for homeowner use include acephate, bifenthrin, carbaryl, cyfluthrin, lambda cyhalothrin, permethrin or spinosad. Sprays should thoroughly cover both upper and lower leaf surfaces. Soil drenches or granular applications of dinotefuran or imidacloprid will control sawfly larvae. Bacillus thuringiensis will only control true caterpillars and not the larvae of sawflies.
