Product details
Ergon Fungicide by Rallis India
Kresoxim-methyl 44.3% w/w (500 g/L) SC for the listed crop–target uses.
What it controls: The listed diseases in rice, grapes, potato, chilli, maize, cotton, soybean and wheat.
When to use it: The Rallis formulation leaflet describes foliar treatment at disease appearance, from early vegetative to reproductive stages.
What to include: Use the matching crop programme and current pack directions. Do not add a sticker, fertiliser or pesticide without a verified recommendation.
Why Choose This Product? Key Benefits
- 🍃Local leaf penetration: Rallis describes translaminar activity, which means movement through treated leaf tissue.
- 🌫️Surface redistribution: The manufacturer also describes vapour activity. This is not a substitute for coverage or a promise to protect all new growth.
- 🍇Grape mildew coverage: The listed grape targets are powdery mildew and downy mildew.
- 🌾Eight-crop disease scope: All eight crops in the manufacturer’s scope are retained, with their targets kept separate.
- ⚙️Respiration inhibition: Group 11 activity interrupts fungal energy production at the Qo site of mitochondrial complex III.

How It Works: Mode of Action
- Redistribution around treated tissue: Ergon has the local penetration and vapour action described by Rallis as mesostemic activity.
- The respiratory chain is blocked: Kresoxim-methyl acts at the quinone-outside site of complex III in fungal mitochondria.
- Energy supply is reduced: Interference with respiration restricts susceptible pathogen development. It does not establish a fixed duration of protection.
Compare FRAC groups, not just brands, when planning resistance management. A different brand with the same active ingredient is not a different mode of action. Use only approved crop options and local resistance-management advice.

Dosage & Application Guide
Rates and foliar directions are from a Rallis Indian formulation leaflet, cross-checked against the 2025 CIBRC formulation compilation. Neither establishes that every direction is current for the pack in hand; the conflicting PHIs are held below.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 242.8–283.3 600–700 ml/ha |
202.3 500 L/ha |
See note* | 7 |
| Rice | 202.3 500 ml/ha |
202.3 500 L/ha |
See note* | 30 |
| Maize | 202.3 500 ml/ha |
202.3 500 L/ha |
See note* | 25 |
| Other five crops* | 202.3 500 ml/ha |
202.3 500 L/ha |
See note* | See note* |
*Other five crops means potato, chilli, cotton, soybean and wheat. Their dose and water agree across sources, but their PHIs conflict and must be confirmed from the current pack before use. No separate label dilution is established for any row.
The Rallis crop table gives potato 23, chilli 3, cotton 26, soybean 43 and wheat 34 days, while the 2025 formulation reference lists 25 days for each. Do not choose the shorter interval or borrow another crop’s interval.
The leaflet records 24-hour re-entry and 2–3 foliar sprays depending on disease pressure. This is not a fixed repeat interval or permission to treat near harvest.
Acre figures are approximate conversions of the stated hectare quantities using 0.40468564224. Keep product and water paired. No per-litre or tank rate has been calculated from area rates.
PHI is the minimum time between the last treatment and harvest, not the worker re-entry interval. Follow current label and local restrictions; missing instructions must be resolved before application.
How to Apply: Best Practices
- Check disease and harvest timing: Identify the matching crop–disease pair. Resolve the five held PHIs before using those crop programmes.
- Use the documented foliar route: The Rallis formulation leaflet specifies high-volume foliar spraying with a hollow-cone nozzle. It describes early vegetative to reproductive stages, at disease appearance.
- Prepare and apply: Premix the measured fungicide with a little water, then add the remaining crop water volume while stirring. Use calibrated equipment for even foliage coverage.
- Choose suitable conditions: The leaflet favours morning or evening and excludes rainy, windy and hot sunny periods. Do not apply at crop maturity or just before harvest.
- Plan later work: Observe the documented 24-hour re-entry and verified crop PHI. Follow disease-pressure and resistance guidance rather than an automatic repeat schedule.
Frequently Asked Questions
1. Is Ergon a fully systemic fungicide?Rallis describes it as mesostemic, with translaminar and vapour actions. Do not interpret those properties as guaranteed movement into every untreated part of the plant.
2. Why is the grape rate different?The Rallis formulation table lists 600–700 ml/ha for grapes, compared with 500 ml/ha for the other seven crops. Each uses 500 L/ha in that table.
3. Why are five harvest intervals held?The Rallis crop table and the later formulation compilation disagree for potato, chilli, cotton, soybean and wheat. A current pack or manufacturer clarification is needed; the crops and agreed doses are not omitted.
4. Can I repeat it every 10–15 days?No fixed repeat interval has been verified. The leaflet describes 2–3 foliar sprays according to disease pressure, with harvest and resistance constraints.
5. Can I mix it with other products?No blanket tank-mix compatibility is established here. Use a mixture only when the current labels and qualified crop advice support it; a physical jar test alone does not prove crop safety or legal approval.
