Prolonged leaf wetness is not required for infection by p owdery mildew, but high humidity is, so providing good air circulation is still important. Damaged or senescent plant parts are a very common way in which the fungus gains entry to the plant. It kills the fungus at its root, and appears to be effective against a number of different types of fungus, including blackspot, powdery mildew, box blight, and rust.The following products contain a combination of both insecticide and fungicide, enabling the control of both damaging invertebrates and disease: triticonazole containing acetamiprid (Roseclear Ultra, Roseclear Ultra Gun). In some circumstances a systemic shoot infection can develop, leading to leaf death and shoot die-back.
Additionally, the fungicides tebuconazole (Provanto Fungus Fighter Concentrate) and triticonazole (Fungus Clear Ultra) are labelled for the control of other diseases on ornamental plants, and could therefore be used legally on Cornus(at the owner’s risk) to try and control anthracnose.The rust fungi are described as biotrophs; that is, they grow within the living tissues of the plant and extract nutrients fromthe cells over an extended period. Spray at the first signs of disease and repeat every seven to fourteen days, depending on disease levels.
