In South Africa, cutworms attack the Cape gooseberry in seedbeds, red spiders in the field, and potato tuber moths near potato fields. Hares damage young plants, and birds eat the fruits. Mites, whiteflies, and flea beetles can be problematic. Powdery mildew, soft brown scale, root rot, and viruses may affect plants. In New Zealand, plants can be infected by "Candidatus liberibacter" subsp. "solanacearum".
