Lime Sulphur | Horticultural Dormant Spray | Fungicide & Insecticide | 10L

Lime Sulphur Horticultural Dormant Spray – 10L Concentrate

Tackle fungal diseases, mites, and overwintering insects at scale with Lime Sulphur 10L — a proven, OMRI-registered horticultural concentrate for fruit trees, small fruit, and ornamentals. Applied as a dormant spray in late winter or early spring before bud break, it penetrates bark crevices to eliminate fungal spores, scale insects, and mite eggs before the growing season begins. The 10L size is ideal for orchards, hobby farms, and acreage operations requiring larger-volume applications.

Key Features

• OMRI registered — approved for use in certified organic production programs
• 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 — spray 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)
• Bulk 10L size — economical for orchards, hobby farms, and multi-tree or multi-row 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 on a cool, overcast day — avoid hot or sunny conditions to prevent leaf burn.
3. Allow the mixture to sit on plant surfaces 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.
