Chemical active ingredients and dual mode of action
- Fluxapyroxad (Xemium active): Advanced carboxamide / SDHI (FRAC Group 7) that inhibits succinate dehydrogenase at Complex II; possesses unique lipophilic and hydrophilic mobility, penetrating waxy cuticles and redistributing continuously through plant vascular systems.
- Pyraclostrobin: High-potency strobilurin (FRAC Group 11 / QoI) that blocks mitochondrial electron transport at Complex III; inhibits fungal spore germination on contact.
- AgCelence physiological benefits: Enhances nitrate reductase enzyme activity, reduces ethylene stress production, and boosts photosynthetic greening for improved pod filling.
CIBRC approved crops and target fungal diseases
Approved in India for managing Target leaf spot, Aerial web blight, and Anthracnose in soybean; Tikka disease (early and late leaf spot) and Rust in groundnut; and Corynespora leaf spot in cotton. Applying preventively or at initial disease symptom onset preserves green leaf area index during pod and boll development.
Application timing, dosage and safety
- Apply at 40 to 45 days after sowing in soybean and groundnut during vegetative branching or early flowering stages.
- Dilute according to CIBRC approved label recommendations in 150 to 200 liters of water per acre using a hollow cone nozzle.
- Observe the mandatory Pre-Harvest Interval (PHI) specified on the container label before harvest.
- Wear personal protective gear and avoid spraying during high wind conditions.

Common questions
What are the active chemical ingredients in Priaxor fungicide?
Priaxor contains Fluxapyroxad (167 g/l) + Pyraclostrobin (333 g/l) formulated as a Suspension Concentrate (SC).
What physiological benefits does Priaxor provide to oilseed crops?
Through its AgCelence physiological effect, Priaxor enhances nitrogen assimilation, reduces stress ethylene synthesis, and keeps leaves green longer for fuller seed filling.
Which major crops is Priaxor recommended for in India?
It is widely recommended for disease control in soybean, groundnut, and cotton under CIBRC label approvals.
