How It Works: Mode of Action
A contact, multi-site fungicide that interferes with several fungal metabolic processes and inhibits spore germination.
- Surface exposure: Susceptible fungal spores and growth encounter chlorothalonil on treated plant surfaces.
- Multiple processes affected: The active ingredient disrupts several fungal enzyme and metabolic processes rather than one narrowly defined target.
- Germination inhibited: Disruption of these processes interferes with spore germination and further fungal development.
Changing the brand name alone does not change the mode of action. Follow label and local resistance-management advice; control of resistant populations is not guaranteed.

Dosage & Application Guide
The quantities below are from the manufacturer’s product information. Confirm the complete current pack programme before application; a stated product amount does not supply missing directions.
Crop-Specific Product Quantities & Application Checks
| Crop | Product quantity | Spray water | Harvest interval | Method |
|---|---|---|---|---|
| Grapes | Approx. 80.94 g/acre | Confirm on pack | 60 days | Foliar spray |
| Potato | Confirm on pack | Confirm on pack | 14 days | Foliar spray |
| Cauliflower | 2 g/L of water | Confirm on pack | 3 days | Foliar spray |
| Watermelon | 2 g/L of water | Confirm on pack | 3 days | Foliar spray |
| Chilli | Approx. 324 g/acre | Confirm on pack | 10 days | Foliar spray |
| Groundnut | Confirm on pack | Confirm on pack | 14 days | Foliar spray |
| Apple | Approx. 80.94 g/acre | 10 L/tree | 45 days | Foliar spray |
Grapes and apple: the manufacturer states 200 g/ha, equivalent to 80.937128448 g/acre (approximately 80.94 g/acre). Chilli: 800 g/ha equals 323.748513792 g/acre (approximately 324 g/acre). Each per-hectare product quantity is multiplied by 0.40468564224 to give the per-acre quantity. Cauliflower and watermelon remain at 2 g/L of water; apple water remains 10 L/tree.
Potato and groundnut product amounts have unresolved scale conflicts and require pack confirmation. Water quantities for crops other than apple lack a clear area basis. For grape and apple canopies, confirm the full current label programme; the apple acre quantity and per-tree water do not establish a tank concentration without a verified orchard programme.
Do not mix with oils. Confirm the exact crop stage, spray interval, maximum applications and re-entry on the current pack. A surface-persistence claim is not a repeat-spray instruction.
How to Apply: Best Practices
- Confirm the exact use: Check the formulation, crop and target against the supplied label before preparing a spray.
- Use the stated route: Follow the manufacturer’s foliar-spray directions under the current crop-specific label.
- Do not mix with oils: Follow this manufacturer restriction. Do not assume compatibility with other products, and do not exceed the labelled dose.
- Record and observe: Record the product, crop and treatment date. Follow label harvest and field-entry requirements.
