Superior Lime Sulphur | Horticultural Dormant Spray | Fungicide & Insecticide | 1 Litre

Lime Sulphur Horticultural Dormant Spray

Take control of fungal diseases and overwintering insects before the growing season begins. Superior Lime Sulphur is a time-tested horticultural concentrate used as a dormant spray on fruit trees, ornamentals, and perennials. Applied in late winter or early spring before bud break, it eliminates fungal spores, mites, scale insects, and other pests that overwinter in bark crevices and garden debris.

Key Features

• Dual-action formula — controls both fungal diseases and overwintering insects and mites in a single application
• Dormant spray use — apply in late winter or early spring before plants leaf out for maximum effectiveness
• Penetrates bark crevices — reaches fungal spores and pest eggs hiding in fissures and plant debris
• Soil application — can also be sprayed around the base of previously infected plants to reduce soil-borne spore load
• In-season use — diluted solution can be applied to actively growing plants showing early signs of fungal disease (avoid hot, sunny days)
• Concentrate formula — economical; mix to the appropriate rate for dormant or in-season applications

How to Use

1. Dormant application (recommended): Mix with horticultural oil and water. Apply in late winter or early spring before bud break. Spray all bark surfaces, crotches, and surrounding soil thoroughly.
2. In-season application: Mix at 1 tsp per gallon (5 mL per 4 L) of water. Apply to all plant surfaces on a cool, overcast day — avoid hot or sunny conditions to prevent leaf burn.
3. Allow the mixture to sit on plants for 15–20 minutes, then rinse thoroughly with clean water.
4. Spray the soil around the base of plants that have been previously infected or are prone to fungal disease.
5. Repeat as needed, following label directions for timing and rates.
