Why Choose This Product? Key Benefits
-
🛡️ Preventive protection: The leaflet directs preventive treatment against its named crop–disease combinations.
-
🌿 Systemic fungicide: AgroStar describes protective and curative activity; correct diagnosis and timely treatment still matter.
-
⚙️ Two modes of action: Azoxystrobin acts on fungal respiration, while tebuconazole acts on sterol production.
-
💧 Liquid SC formulation: Measure the suspension concentrate and mix it with water for the crop-specific spray programme.

How It Works: Mode of Action
Correct target identification, label-directed timing and coverage are essential to responsible use.
-
Respiration inhibition: Azoxystrobin inhibits electron transfer at the Qo site of fungal mitochondrial complex III, affecting energy production.
-
Sterol-biosynthesis inhibition: Tebuconazole inhibits C14-demethylase, disrupting the production of sterols needed for fungal cell membranes.
-
Use both actives responsibly: The combination brings together FRAC Groups 11 and 3. It does not remove resistance risk; follow the supplied label and an appropriate fungicide-rotation plan.
Target Crops & Diseases
Use only the following crop–target combinations on the current supplied label. A target listed for one crop does not authorise its use on another.

Dosage & Application Guide
Use each row only for that crop and its disease pairing in the target table. Product quantities below refer to the formulated fungicide, not pure active ingredient. For potato, rice and wheat, obtain the complete crop-specific dose, water, timing and harvest directions from the current supplied label and a qualified crop adviser before mixing.

Route and timing: Apply as a foliar spray preventively. The leaflet gives a 15-day repeat interval depending on weather conditions and disease pressure; this is not an instruction to spray automatically. Follow the current label’s treatment limits.
Acre quantities are approximate conversions of the original hectare rates retained in the table. Apple is a concentration-based programme with water per tree, not a per-acre dose. Do not derive a universal per-litre, pump or pack-coverage recipe from the field rates.
Harvest and entry: Keep the stated waiting period after the last spray before harvesting. PHI is not a worker re-entry interval; follow separate entry restrictions and protective measures. An unstated harvest or worker-entry interval must not be treated as zero.
How to Apply: Best Practices
-
Match crop and disease: Check the current supplied Roztam label and identify the crop–disease pair. Do not transfer potato late-blight directions to tomato.
-
Measure accurately: Use a dedicated measuring tool for the stated amount of formulated product. Match the treatment area or apple tree programme, not the size of the bottle.
-
Prepare the mixture: Add the measured fungicide to a small quantity of water. Stir thoroughly with a stick or rod, add the remaining required water and stir again.
-
Apply to foliage: Use calibrated spray equipment and the specified crop water volume. Avoid inhaling mist and prevent drift or runoff into water bodies.
-
Plan repeats carefully: Apply preventively and reassess weather and disease pressure before a label-permitted repeat. Observe the crop’s final-spray-to-harvest interval.
-
Protect aquatic life: Do not use near aquaculture. Keep spray liquid, washings and containers away from drains, ponds, streams and other water sources.
AgroStar lists compatibility with sticking agents. This is not approval for every adjuvant or tank mixture: confirm the exact partner, rate and crop on both current labels before mixing. A jar test alone does not establish legal use, crop safety or effectiveness.
Frequently Asked Questions
SC means suspension concentrate. Roztam contains azoxystrobin 11% plus tebuconazole 18.3% w/w and is measured as liquid product before mixing with water.
No. Pack size is the quantity purchased, not an application rate. Match the crop, disease, treatment area and label water volume; apple has a separate per-litre and per-tree programme.
No. The Roztam leaflet pairs tomato with early blight only. It lists both early and late blight for potato, and those directions must not be transferred between crops.
The label uses 1 ml of formulated product per litre of water with 8–12 litres of water per tree and a 10-day harvest interval. Apply preventively as directed; do not turn this into an assumed per-acre rate.
