Sumil Chemicals S-cross Fungicide (Tebuconazole 10% + Sulphur 65% WG) is a broad-spectrum combination fungicide designed for the management of important fungal diseases in chilli and soybean. It combines the systemic action of Tebuconazole with the contact and vapour activity of Sulphur for complementary crop protection.
S-cross provides both preventive and curative fungicidal activity. It is recommended against powdery mildew and fruit rot in chilli and leaf spot and pod blight in soybean when applied at the recommended crop and disease stage.

| Activity | Preventive and Curative |
| Application Method | Foliar Spray |
| Recommended Crops | Chilli and Soybean |
| Active Ingredient | Content | Function |
|---|---|---|
| Tebuconazole | 10% | Systemic fungicide with preventive and curative activity |
| Sulphur | 65% | Contact fungicide with protective and vapour-phase activity |
| Formulation | Water Dispersible Granules (WG) | |
| Crop | Target Disease | Recommended Dose | Approx. Dose per Acre | Water Volume |
|---|---|---|---|---|
| Chilli | Powdery Mildew & Fruit Rot | 1.25 kg/ha | Approx. 500 g/acre | 500 L/ha |
| Soybean | Leaf Spot & Pod Blight | 1.25 kg/ha | Approx. 500 g/acre | 500 L/ha |
The registered recommendation for this formulation is approximately 1.25 kg per hectare, equivalent to about 500 g per acre, using approximately 500 litres of water per hectare. Always confirm the current S-cross label before application.
Apply S-cross at the early appearance of fungal disease. Early application helps protect healthy crop tissues and manage infection before disease pressure becomes severe.
The registered formulation guidance allows approximately 2–3 sprays depending on disease infestation. Application frequency should always follow the current product label and field conditions.
| Crop | Waiting Period |
|---|---|
| Chilli | 5 Days |
| Soybean | 26 Days |
The registered re-entry period is approximately 24 hours. Follow the latest product label for final harvest and re-entry instructions.
Tebuconazole is a systemic triazole fungicide that interferes with sterol biosynthesis in susceptible fungal pathogens. Sterols are essential for normal fungal cell membrane formation, and disruption of this process restricts fungal growth and development.
Sulphur acts primarily as a contact fungicide and also provides vapour-phase activity around treated plant surfaces. It interferes with fungal respiration and other metabolic processes, helping reduce spore germination and disease development.
The combination provides internal systemic protection together with protective surface activity for broader disease management.
Powdery mildew generally appears as white or grey powder-like fungal growth on chilli leaves and other plant surfaces. Heavy infection can reduce photosynthetic area and weaken crop development.
S-cross is recommended at approximately 500 g per acre for management of powdery mildew and fruit rot in chilli. Apply at the early appearance of symptoms for better disease suppression.
Fruit rot can affect developing chilli fruits and may produce lesions, tissue breakdown and reduced marketable quality under favourable disease conditions.
The combination of Tebuconazole and Sulphur helps protect susceptible plant tissues and manage fungal development when applied according to the recommended schedule.
Leaf spot diseases can produce discoloured or necrotic lesions on soybean foliage. Severe infection can reduce healthy leaf area and interfere with normal crop growth.
S-cross provides systemic and contact fungicidal activity for management of label-recommended soybean leaf spot disease.
Pod blight can affect reproductive plant parts and may interfere with pod and seed development when disease pressure is high.
Timely application at the early appearance of disease helps protect developing soybean plants and pods from susceptible fungal infection.
The Sulphur component provides protective contact and vapour-phase fungicidal activity. Sulphur is also known to have secondary activity against susceptible mites in appropriate crop-protection uses.
However, S-cross should only be used against crop diseases and other targets specifically permitted on the current product label.
Apply S-cross when fungal disease is first observed or when environmental conditions favour disease development. Preventive or early-stage application is generally more effective than waiting until severe infection develops.
Avoid spraying during extreme weather conditions and follow the current product label regarding rainfall, temperature and crop-stage precautions.
S-cross combines the internal activity of Tebuconazole with the external protective action of Sulphur. Tebuconazole moves into treated vegetative tissues, while Sulphur remains primarily on plant surfaces and provides protective contact activity.
This two-way approach helps provide preventive and curative disease-management benefits when the product is applied correctly.
