Active chemical composition and dual biochemical action
Merivon combines a carboxamide (SDHI) with a strobilurin (QoI) to establish comprehensive multi-stage fungal disease control.
Fluxapyroxad inhibits complex II (succinate dehydrogenase) in the fungal mitochondrial respiratory chain, while Pyraclostrobin blocks complex III electron transfer. This dual energy shutdown arrests fungal spore germination, germ tube elongation, and mycelial growth.
- Fluxapyroxad (250 g/L SC): Advanced Xemium carboxamide delivering continuous systemic mobility and curative kickback.
- Pyraclostrobin (250 g/L SC): Broad-spectrum strobilurin providing protective surface adherence and plant health enhancement.
- AgCelence benefit: Improves crop physiological stress tolerance, enhances photosynthesis, and improves marketable fruit finish.
Target horticultural crops and approved disease spectrum
Merivon is registered for managing destructive fungal pathogens across premium commercial fruit orchards and vegetable crops in India.
It is celebrated for delivering pristine disease control and superior fruit finish in apple, mango, and grape production.
- Apple: Apple scab (Venturia inaequalis) and powdery mildew (Podosphaera leucotricha).
- Mango: Powdery mildew and anthracnose blossom blight.
- Grapes: Powdery mildew on leaves, canes, and developing berry clusters.
- Chilli & Tomato: Powdery mildew and Alternaria leaf spots.
Application timing, dosage adherence, and safety
Apply Merivon preventively at critical phenological stages such as pink bud and petal fall in apples, or flower panicle emergence in mango.
Ensure uniform foliar and fruit cluster coverage using high-pressure orchard sprayers operated at container label recommended dilution rates.
- Preventive timing: Initiate spraying before disease symptoms appear or immediately upon disease forecast alerts.
- Resistance management: Limit consecutive sprays to 2 applications per season, rotating with non-SDHI/non-strobilurin chemistries.
- Protective measures: Wear protective eyewear, rubber gloves, and clean work clothes; respect statutory pre-harvest intervals.
