Product details
Centaurus Fungicide | Tebuconazole 6.7% + Captan 26.9% SC
Centaurus combines systemic tebuconazole with contact captan for specified diseases in chilli and apple. The formulation brings a sterol-biosynthesis inhibitor together with a multi-site protective component.
What it controls: Specified diseases in chilli and apple.
When to use it: Within a preventive or permitted early-disease programme.
What to include: Complete canopy coverage and the correct crop water basis.
Why Choose This Product? Key Benefits
-
๐ฟSystemic and contact components: Tebuconazole acts within treated plant tissue while captan provides activity at the treated surface.
-
๐ฏDifferent modes of action: The combination joins Group 3 sterol-biosynthesis inhibition with Group M04 multi-site activity.
-
๐ฑSpore-germination protection: Captan interferes with thiol-containing fungal enzymes and helps prevent spores from establishing infection.
-
๐ฌUptake through plant tissue: Tebuconazole is absorbed by vegetative parts and moves upward through the xylem.
-
๐ก๏ธTwo distinct crop programmes: The chilli and apple uses cover different disease sets. Keeping those programmes separate avoids copying orchard directions into a vegetable crop.

How It Works: Mode of Action
Centaurus combines a systemic DMI component with a multi-site contact protectant. Their movements and biochemical targets are different.
-
Protect treated surfaces: Captan acts on fungal spores at the plant surface and inhibits germination through multi-site enzyme effects.
-
Move within the plant: Tebuconazole is absorbed into vegetative tissue and translocated acropetally in the xylem.
-
Restrict fungal membrane synthesis: Tebuconazole inhibits sterol demethylation, limiting fungal membrane formation and growth.
Use the mode-of-action group, not the brand name alone, when planning resistance management. Avoid repeated reliance on the same group.

Dosage & Application Guide
Chilli uses an area-based foliar programme. Apple uses a per-tree water basis and must not be assigned a guessed water volume per acre.

Approximate acre equivalents retain the original hectare figures below them. Match each product amount with its stated water volume and harvest interval.
Apple scab: foliar spray at 2.5 ml/L (0.25%) using 10 L water/tree; leave 10 days between the last spray and harvest. This is a concentration-and-tree programme, not an acreage rate.
Apple powdery mildew and Alternaria leaf spot/blight remain supported targets, but their complete numerical programme is withheld here. The leaflet combines an area-based product amount with per-tree water without establishing the tree-density link needed for a complete recipe. Confirm the full product, water, stage, repeat and harvest programme for the supplied pack before treatment; do not infer a per-tree dose or copy the separate scab programme.
No additional per-litre chilli rate is derived. Use its area-based product amount and matching water volume.
How to Apply: Best Practices
-
Application route: Foliar spray, using the crop-specific water basis and thorough canopy coverage.
-
Timing: Apply preventively during the vegetative stage or at disease appearance as directed by the leaflet. For the verified chilli and apple-scab programmes above, repetition is at 15-day intervals according to weather and disease pressure; observe the corresponding harvest interval. This does not clear the separately withheld apple powdery-mildew/Alternaria programme.
-
Equipment and coverage: Use a knapsack or foot sprayer fitted with a hollow-cone nozzle. Cover the crop evenly and do not spray in windy conditions.
-
Use restrictions: Do not use for post-harvest application or in areas where pisciculture or aquaculture is practised.
-
Mixing: Use only the mixtures and preparation directions allowed by the supplied label. A physical mixing test does not establish crop safety.
-
After use: Clean application equipment safely, wash exposed skin and change contaminated clothing. Keep washings away from drains and surface water.
Frequently Asked Questions
What does the formulation code mean?
SC means suspension concentrate. Centaurus contains tebuconazole 6.7% w/w and captan 26.9% w/w; neither percentage is a spray concentration.
Are the chilli and apple directions interchangeable?
No. Apple is an orchard crop and chilli is a vegetable crop. Their disease lists, water basis and harvest restrictions must remain matched to the appropriate use.
Is Centaurus only a contact fungicide?
No. Captan is the contact multi-site component, while tebuconazole is systemic. Neither component removes the need for careful canopy coverage.
Can it be mixed with another pesticide or nutrient?
Use only a mixture permitted for the exact crop and products by their supplied labels. A jar test checks physical mixing only; it does not prove crop safety, efficacy or approval.
What should be checked before application?
Check the supplied label for product amount, water, timing, harvest and re-entry restrictions, protective equipment and any crop-specific precautions.
Safety & Disclaimer
Read and follow the supplied product label and accompanying leaflet. Use only for the stated crop, target and application conditions, and observe the applicable dose, waiting periods and precautions.
Avoid inhalation and contact with eyes and skin. Do not eat, drink or smoke during mixing or application. Store closed in its original container away from food, feed, heat and children.
Do not reuse empty pesticide containers. Follow label disposal instructions and keep product and washings out of ponds, streams and drains. Wear suitable respiratory protection, protective gloves, chemical-resistant boots and goggles or safety glasses. Wash protective clothing before reuse and wash hands thoroughly after handling. The product can irritate the eyes, skin and upper respiratory system and cause skin sensitization. Seek medical attention promptly after suspected poisoning, taking the product label. Do not induce vomiting unless directed by the attending physician, and never give anything by mouth to an unconscious person.
