Dual Modes of Action and Cellular Respiration Targets
This advanced fungicide combines Fluxapyroxad (succinate dehydrogenase inhibitor - SDHI) with Pyraclostrobin (quinone outside inhibitor - QoI).
By shutting down fungal mitochondrial respiration at two distinct cellular sites (Complex II and Complex III), it stops ATP energy synthesis in pathogenic fungi with exceptional efficacy.
- Fluxapyroxad (SDHI): Inhibits mitochondrial Complex II, providing long-lasting systemic translaminar protection
- Pyraclostrobin (Strobilurin): Inhibits Complex III respiration, providing potent spore-kill and physiological vitality
- Superior mobility: Rapidly redistributes within plant waxes and translocates across leaf surfaces
Target Crop Diseases and Physiological Benefits
The combination is registered to manage stubborn fungal complexes in soybean, cotton, groundnut, and horticultural crops.
Beyond disease protection, the strobilurin component enhances nitrate reductase activity, decreases ethylene stress synthesis, and optimizes water use efficiency.
- Soybean: Control of sheath blight, target spot, and rust complexes
- Groundnut: Suppression of early and late leaf spots (Tikka) and stem rot
- Physiological vitality: Promotes greener foliage, delayed senescence, and enhanced seed filling
Spraying Instructions and Resistance Management
Apply preventively at the onset of disease-favorable weather conditions or at the earliest visible foliar lesions.
To safeguard this chemistry against pathogen resistance development, avoid sequential applications exceeding label limits and rotate with multi-site contact fungicides.
- Spray calibration: Use hollow cone nozzles with adequate clean water to ensure thorough foliar coverage
- Spray rotation: Alternate with contact fungicides like Mancozeb or Chlorothalonil across crop seasons
- Harvest intervals: Observe pre-harvest waiting periods as specified on the registered product container

Common questions
What chemical classes do Fluxapyroxad and Pyraclostrobin belong to?
Fluxapyroxad belongs to the carboxamide/SDHI class, while Pyraclostrobin is a strobilurin/QoI fungicide.
How does this combination improve crop physiological greening?
The strobilurin component reduces ethylene production during environmental stress and enhances photosynthesis, keeping leaves green longer.
Is the fungicide mixture translaminar?
Yes, both active compounds penetrate leaf tissues and redistribute translaminarly to protect both upper and lower leaf surfaces.
