Dual-Action Fungicide Chemistry
Priaxor pairs a succinate dehydrogenase inhibitor (SDHI, FRAC Group 7) with a QoI strobilurin (FRAC Group 11). This dual-mode mechanism inhibits cellular respiration in fungal mitochondria at two distinct biological sites, suppressing spore germination, germ tube elongation, and mycelial growth.
The active ingredients exhibit excellent systemic mobility, redistributing continuously through plant vascular systems as foliage expands.
- Soybean: Frogeye leaf spot, anthracnose, Rhizoctonia aerial blight, and Asian soybean rust.
- Groundnut: Early leaf spot (Cercospora), late leaf spot (Phaeoisariopsis), and rust.
- Cotton: Alternaria leaf spot, grey mildew, and Corynespora leaf spot.
- Plant health: Enhances nitrate reductase activity and chlorophyll retention, supporting stress resistance.
Recommended Application Practices
Preventative application at early disease onset delivers optimal efficacy. Ensure thorough canopy coverage using a hollow cone or fine mist nozzle fitted to a calibrated sprayer.
Applying before heavy fungal pressure develops preserves leaf area and maximizes photosynthetic grain filling.
- Spray early in the morning when wind drift is minimal and ambient humidity facilitates uniform leaf drying.
- Alternate with fungicides of different FRAC groups to prevent the development of resistant fungal strains.
- Always observe approved pre-harvest intervals and water volumes specified by the official product label.

Common questions
What active ingredients constitute Priaxor?
Priaxor contains Fluxapyroxad (Xemium carboxamide) and Pyraclostrobin (strobilurin), delivering synergistic preventative and curative disease control.
Does Priaxor help crops withstand environmental stress?
Pyraclostrobin is documented to promote physiological benefits including enhanced nitrogen assimilation and reduced ethylene accumulation during dry spells.
When should Priaxor be applied in soybean?
Preventative application at the initiation of flowering or early pod formation protects foliage against mid-to-late season foliar blights.
