Dramatically reduces and inhibits common scab, such an unsightly blemish on potato skins. Contains 90% elemental sulphur and 10% clay as a binding agent. Completely safe not harmful to people, plants or animals. Since the Clean Air Acts, sulphur deposition from atmospheric pollution has fallen dramatically. Sulphur is essential for plant growth.When applying Brimstone, the soil oxidizes to form a weak sulphuric acid which provides a seasonal lowering of soil pH and a controlled release of the nutrient sulphate. Apply a continuous band of Brimstone along the potato ridge after planting, 15g/metre (--oz/yard). A 600g pack will treat 40 metres of row and the soil will remain acidified until autumn.Also excellent for onions and shallots, and ericaceous plants.
