Ensure that any leaves falling prematurely from an infected plant are collected up and disposed of (by burning, burial or consigning to the council green waste). Heavily-infected shoots could be trimmed off and disposed of in the same way. Pour liquid from the dosing chamber into the sprayer and make up to 1 litre with water. Replace cap A white powdery fungal growth on the surface of leaves, buds, petals and shoots of roses and many other plants. The foliage may become discoloured, heavily infected young leaves may be curled and distorted, and the plant’s vigour may be reduced. powdery mildew ( Podosphaera fuliginea) and grey mould ( Botrytis cinerea).

Spray at the first signs of disease and repeat every seven to fourteen days, depending on disease levels.Spray the whole plant evenly until just before run-off (before drips start to form at the tips of leaves). Theproducts above also have recommendations for control of powdery mildew, as do products containing sulphur(Fungus Clear Ultra 2, Mildew Clear for Edibles, Roseclear 3-in-1 action (with fatty acids)). Stemphyliumsp. causessmall, dark brown or purple spots on the leaves. The spots do not merge together, nor enlarge in size. The centre of the lesion can sometimesbecome pale in colour. The infected leaves shrivel prematurely and can either remain on the plant or drop off.

Under certain environmental conditions some Stemphylium speciesare thought to be able to produce a sexual stage, and spores liberated from the fruiting bodies of the fungus in this scenario could account for the overwintering survival of the fungus and its long distance dissemination. PLEASE NOTE: Turf, Wildflower Turf, Sedum Mats and bulk Bag products are delivered on a pallet and can only be delivered to the kerbside.Distorted leaves are often the first sign of infection, especially with the larger-leaved cultivars. A grey/mauve felt-like 'fungal' growth appears on the under-surface of the leaves, with diffuse purple-red or yellow patches developing on the corresponding upper surface. Pour liquid from the dosing chamber into the sprayer and make up to 1 litre with water. This will treat a lawn area of up to 20m² The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivarselection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner. Non-chemical control

Apply no more than four times per year on roses and ornamentals and no more than six times per year on box trees. How to Use Then rinse sprayer thoroughly after use and dispose of washings safely by pouring onto bare soil. Once the bottle is empty, RINSE CONTAINER THOROUGHLY before disposal by manually rinsing three times. This can be done by filling the dosing chamber with clean water, replacing the cap and tipping the water into the bottle. Repeat steps 1 – 4 above to add washings to sprayer at time of filling and dispose of empty container safely.Downy mildewrequires cool wet weather for infection and spread. The 'fungal' growth seen on the underside of the leaves produces large numbers of asexual spores.Downy mildews are host-specific, so for example thedowny mildew affecting a Veronica will not infect a rose or vice versa. Prolonged leaf wetness is not required for infection by p owdery mildew, but high humidity is, so providing good air circulation is still important. Avoid drought stress and the overuse of nitrogenous fertilisers.
