Dual active chemistries and physiological action
Merivon combines two complementary modes of action for superior disease management.
Technical breakdown of constituents:
- Fluxapyroxad (Xemium - 250 g/L): Belongs to the carboxamide / SDHI group (FRAC Group 7), inhibiting fungal succinate dehydrogenase (Complex II) in cellular respiration.
- Pyraclostrobin (F500 - 250 g/L): Belongs to the strobilurin / QoI group (FRAC Group 11), blocking electron transfer at Complex III in fungal mitochondria.
- Dual-stage mobility: Fluxapyroxad moves continuously within the plant xylem while forming crystalline depots on the leaf surface for sustained redistribution.
- AgCelence plant health benefits: Pyraclostrobin promotes nitrate reductase activity, decreases ethylene stress synthesis, and enhances leaf greening and fruit firmness.
Target crops and major plant diseases
Merivon is registered for protecting premium horticultural and cash crops:
Primary disease spectrum:
- Apples: Apple scab (Venturia inaequalis) and powdery mildew (Podosphaera leucotricha) during pre-bloom and petal-fall stages.
- Grapes: Powdery mildew (Uncinula necator) and anthracnose.
- Chilli: Anthracnose fruit rot and powdery mildew.
- Mango: Blossom blight, anthracnose, and powdery mildew during panicle emergence.
Application guidance, pricing and resistance safeguards
Apply Merivon preventatively before disease symptoms emerge or at early infection onset using CIBRC-prescribed label rates. Retail pricing depends on pack size, local distribution, and dealer networks. To safeguard these premium chemistries against resistance, limit consecutive applications and rotate with multi-site contact fungicides. Wear appropriate protective clothing and observe mandatory pre-harvest intervals.

Common questions
What active ingredients make up Merivon fungicide?
Merivon contains Fluxapyroxad 250 g/L (SDHI) plus Pyraclostrobin 250 g/L (Strobilurin) SC.
How does Merivon deliver curative as well as preventive disease control?
Fluxapyroxad penetrates internally to stop existing fungal hyphae, while Pyraclostrobin and surface deposits prevent new spore germination.
What factors influence the retail price of Merivon fungicide?
Packaging size (e.g. 80 ml, 250 ml), dealer distribution logistics, and seasonal demand determine local retail prices.
