HOW TO CONTROL POWDERY MILDEW

Prune out infected shoots of plants and destroy, by burning if possible. Keep plants well spaced and improve ventilation around them.

Fruit trees, grapes and vegetables > Apply ORGANIC SUPER SULPHUR as advised on the label instructions.

Roses and ornamentals > Apply SUPER SPECTRUM regularly every 14 days to treat infected plants. Once disease is controlled you can use SPECTRUM as a preventative treatment.

Disease is often carried between plants by sap sucking insects. Use ORGANIC SUPER SPRAYING OIL to control these insects before they can spread disease.
