David Grays Lime Sulphur 500ml – Insecticide & Fungicide Concentrate for Fruit Trees & Roses

David Grays Lime Sulphur 500ml: Dual Insecticide and Fungicide Concentrate

David Grays Lime Sulphur is a dual-action insecticide and fungicide that controls both fungal diseases and certain pests on fruit trees, roses, other ornamentals and berries. The active constituent is sulphur (present as polysulfide sulphur), supplied as a 500ml concentrate that's diluted with water before spraying. It's a long-established garden treatment valued for tackling disease and mites in one product, particularly as a clean-up spray on dormant deciduous fruit trees over winter.

On the disease side it controls leaf curl, shot hole, freckle, rust, black spot and powdery mildew, and it also controls scale. As a miticide it works on two-spotted mite, bryobia mite and red spider mite. That broad activity makes it a common choice for a winter clean-up program, knocking back overwintering pests and disease spores before the new season's growth begins.

What It Controls

• Diseases: leaf curl, shot hole, freckle, rust, black spot and powdery mildew
• Scale
• Mites: two-spotted mite, bryobia mite and red spider mite
• For use on fruit trees, roses, other ornamentals and berries

Important Timing and Plant Cautions

Lime sulphur has some specific restrictions that matter for avoiding plant damage, so check these before spraying:

• Do not apply during the growing period to apricots, peaches or other sulphur-sensitive plants
• Do not use on Delicious or Cox's Orange Pippin apples
• Do not apply when freezing weather is expected, or during abnormally hot periods
• Do not apply within a few weeks of an oil spray such as white oil, as sulphur and oil together can burn foliage

Because of these cautions, lime sulphur is most often used at the right growth stage, such as on dormant trees in winter, rather than sprayed indiscriminately during active growth.

How to Use It

Lime sulphur is a concentrate, so mix it with water at the rate on the label for the plant and problem you're treating, and spray to give thorough coverage of the plant, including stems and both sides of the leaves. Rates differ between dormant and growing-season use, so follow the label for the correct dilution and timing. It has a strong odour and can stain surfaces, so avoid spraying near paintwork, paving and light-coloured surfaces, and wear gloves and eye protection when mixing and applying.
