If the powdery mildew is severe, using a fungicide that includes sulfur can help to manage the disease.
Another disease that might affect Berkheya seminivea is leaf spot disease. Leaf spot manifests as small dark spots on the leaves, which can turn yellow and fall off.

Encouraging the presence of natural predators such as ladybirds and lacewings can also help control the population of aphids.
Berkheya seminivea can also be affected by spider mites. Spider mites cause yellowing of leaves and a fine webbing on the plant. The best way to manage spider mites is to remove any infested parts of the plant and use insecticidal soap to control the population.
