Pests

Weevils on foamflower

Tiarella L.

Foamflower is damaged by the black vine weevil Otiorhynchus sulcatus and Calomycterus setarius, whose larvae destroy the root system, while adults feed on leaf margins.

In the reference 9 varieties crop Foamflower, where this is mentioned in the description.

The primary damage is caused by the larvae, which develop in the soil and feed on the roots, often leading to the death of the crop. Adult beetles leave characteristic notches along the edges of the leaves, which in most cases are only a cosmetic defect.

In cases of severe infestation by Otiorhynchus sulcatus, adult specimens can penetrate the root collar of the foamflower, causing the entire above-ground part of the plant to die off. Foamflower cultivars do not possess specific resistance genes to these pests and are characterized as susceptible.
