Tata Ergon is a broad-spectrum systemic fungicide containing Kresoxim-methyl 44.3% w/w, equivalent to 500 g/L, SC. It is manufactured and marketed by Rallis India Limited, a Tata enterprise, for managing important fungal diseases in rice, grapes, chilli, soybean, potato, cotton, wheat and maize.
Ergon belongs to the strobilurin or QoI fungicide group. It helps control disease by interfering with fungal respiration, inhibiting spore germination and restricting fungal growth. Its translaminar movement, surface redistribution and vapour activity support effective coverage of treated plant parts.
Timely application helps protect healthy plant tissue, preserve functional green leaf area and support crop yield and quality potential. For best performance, use Ergon preventively or during the initial stage of disease development.

Kresoxim-methyl is a FRAC Group 11 Quinone Outside Inhibitor. It binds at the Qo site of the cytochrome bc1 complex and blocks electron transfer between cytochrome b and cytochrome c1 in fungal mitochondria.
Blocking mitochondrial electron transport disrupts ATP and energy production. This inhibits spore germination, fungal growth and development of the disease. The product is particularly effective when applied preventively or during the early stage of infection.
| Crop | Target Disease | Dose per Hectare | Approx. Dose per Acre | Water per Hectare | Waiting Period |
|---|---|---|---|---|---|
| Rice | Blast and sheath blight | 500 ml | Approximately 200 ml | 500 litres | 30 days |
| Grapes | Powdery mildew and downy mildew | 600–700 ml | Approximately 240–280 ml | 500 litres | 7 days |
| Chilli | Powdery mildew, fruit rot or anthracnose, dieback and twig blight | 500 ml | Approximately 200 ml | 500 litres | 3 days |
| Soybean | Rust | 500 ml | Approximately 200 ml | 500 litres | 43 days |
| Potato | Late blight and early blight | 500 ml | Approximately 200 ml | 500 litres | 23 days |
| Cotton | Leaf spot and grey mildew | 500 ml | Approximately 200 ml | 500 litres | 26 days |
| Wheat | Rust and leaf blight | 500 ml | Approximately 200 ml | 500 litres | 34 days |

Dose-conversion note: Acre doses are rounded conversions from the registered hectare recommendations. Always give priority to the dose printed on the supplied Ergon label.
The registered label permits 2–3 foliar sprays, depending on disease pressure. The actual number and interval should be based on disease severity, crop stage, weather, previous application and label directions.
Do not repeat Ergon continuously without rotating to an effective fungicide having a different FRAC mode-of-action group.
In rice, Ergon is registered for blast and sheath blight. Apply at the early stage of disease using 500 ml per hectare in 500 litres of water.
In grapes, Ergon controls powdery mildew and downy mildew. Use 600–700 ml per hectare according to disease pressure and label directions. Thorough coverage of foliage and bunch-bearing portions is important.
In chilli, Ergon is registered for powdery mildew, fruit rot or anthracnose, dieback and twig blight. Use 500 ml per hectare as an evenly applied foliar spray.
In soybean, it is recommended for rust management. Early intervention helps protect functional foliage during crop and pod development.
In potato, Ergon is registered against early and late blight. Begin disease management according to field monitoring and locally favourable infection conditions.
In cotton, Ergon controls leaf spot and grey mildew. Disease management helps retain productive foliage during crop development.
In wheat, Ergon is recommended against rust and leaf blight. Apply during the labelled crop stage and observe the 34-day waiting period.
In maize, Ergon is registered for Turcicum leaf blight and rust. Uniform foliar coverage is necessary for effective protection.
Kresoxim-methyl belongs to FRAC Group 11. Repeated application of Group 11 fungicides can select resistant fungal populations. Ergon should therefore be used within an integrated disease- and resistance-management programme.
Tank mixing may be considered only when the labels of all products permit the combination. Conduct a small jar test before preparing an unfamiliar mixture. Do not use mixtures that produce sediment, flakes, heat, excessive foam or separation.
Compatibility does not automatically confirm crop safety or biological effectiveness. Obtain crop-specific expert advice before combining Ergon with unfamiliar pesticides or fertilizers.
Ergon is known for good retention and redistribution after drying. However, a fixed rainfastness period is not stated in the available registered label information. Allow sufficient drying time and avoid spraying immediately before expected rainfall.
| Safety Requirement | Label Direction |
|---|---|
| Re-entry Period | Do not enter the treated crop for 24 hours after spraying without appropriate protection |
| Pre-Harvest Interval | Observe the crop-specific waiting period stated in the dosage table |
| Unlisted Crops | Do not use on crops other than those specified on the current label |
Ergon is used for managing label-approved fungal diseases in rice, grapes, chilli, soybean, potato, cotton, wheat and maize.
It contains Kresoxim-methyl 44.3% w/w, equivalent to 500 g/L, in a suspension concentrate formulation.
The approximate dose is 200 ml per acre for rice, chilli, soybean, potato, cotton, wheat and maize. For grapes, the approximate rate is 240–280 ml per acre. Follow the hectare dose printed on the label for accurate application.
Apply 500 ml per hectare, approximately 200 ml per acre, in 500 litres of water per hectare for blast and sheath blight.
Apply 600–700 ml per hectare, approximately 240–280 ml per acre, in 500 litres of water per hectare for powdery and downy mildew.
The label recommends 2–3 foliar applications depending on disease pressure. Rotate with a fungicide from a different FRAC group to manage resistance.
Ergon provides contact protection along with systemic and translaminar redistribution. Its vapour activity also contributes to movement around treated plant surfaces.
Ergon is described as having protective, early curative and eradicative activity. Performance is generally best when it is applied preventively or at the beginning of infection. It cannot restore plant tissue that has already been severely damaged.
The registered label specifies a re-entry period of 24 hours after spraying.
The waiting period is 3 days for chilli, 7 days for grapes, 23 days for potato, 25 days for maize, 26 days for cotton, 30 days for rice, 34 days for wheat and 43 days for soybean.
A tank mixture should be prepared only when the labels of all products permit it. Conduct a compatibility test and obtain expert advice before combining unfamiliar products.
Choose Tata Ergon for systemic and translaminar management of labelled blast, blight, mildew, rust, fruit rot, dieback and leaf-spot diseases. Apply during the early disease stage using the crop-specific dose, water volume, application frequency and waiting period stated on the label.
