Keep out of reach of children Do not breathe spray Use only outdoors or in a well-ventilated area If medical advice is needed, have product container or label at hand. Do not over-fertilise (especially not too much nitrogen) as succulent growth is particularly susceptible Most powdery mildew fungi have a host range restricted to a relatively few, related plants, but these can include wild relatives which can be sources of infection, e.g. wild crab apples may be sources of infection for apple orchards. Ensure clean healthy plants with Fungus Fighter Plus Ready to Use, Fungus Fighter Plus is a systemic fungicide that gives long-lasting control for up to 3 weeks.

Symptoms may take the form of purple or brown rings enclosing a green or yellow centre, or they may be solid purple or brown circles Careful pruning of junipers to remove rust infections from the stems, or simply removing whole plants from the vicinity of pear trees will reduce the likelihood of infection, but note that the spores are airborne over quite long distancesPrompt removal of infected leaves early in the season may delay the build-up of the disease slightly, although weather conditions havethe greatest influence over the speed of spread. Dispose of plants at the end of the season. We independently research, review, and recommend the best products. If you buy something through our links, we may earn a commission. Learn more.

Powdery mildew fungi produce microscopic air-borne dispersal spores from the fungal growth on the plant surface. These have an unusually high water content, enabling them to infect under drier conditions than most other fungal pathogens. We independently research, review, and recommend the best products.

These products will also give incidental control of powdery mildew, another foliar disease that can affect antirrhinums.

Prune shrubs to give an open structure (which will again improve air circulation and reduce humidity) The fungus originates from western North America on related species, but proved highly infectious to the European Antirrhinum majus when accidentally introduced to the UK and mainland Europe in the last century. It releases dark brown spores from the pustules on the lower leaf surface and these are spread by the wind to initiate new infections on leaves.
