Active chemical nature and advanced SC formulation
Contaf Plus contains Hexaconazole formulated as a 5% SC (suspension concentrate), offering distinct physical and biological advantages over older emulsifiable concentrate (EC) formulations.
Its fine water-based micro-particles ensure superior foliar coverage, enhanced translaminar absorption, and reduced phytotoxicity risk during sensitive flowering and young flush stages.
- Active chemical: Hexaconazole 5% SC.
- FRAC classification: Group 3 (Demethylation inhibitor / DMI triazole).
- Advanced SC formulation: Water-based, solvent-free, non-flammable, and gentle on delicate crop blossoms.
- Systemic acropetal mobility: Absorbed rapidly by green foliage and translocated upward via xylem vessels to protect emerging shoot growth.
Target crops and approved fungal disease spectrum
Contaf Plus is registered across major cereal, plantation, oilseed, and horticultural fruit crops in India.
It is celebrated for managing sheath blight in rice, powdery mildew in grapes and mango, and tikka disease in groundnut.
- Paddy (Rice): Sheath blight (Rhizoctonia solani) and blast suppression.
- Grapes: Powdery mildew (Uncinula necator) on leaves and berry clusters.
- Mango: Powdery mildew on delicate flowering panicles.
- Groundnut: Tikka leaf spot and rust.
- Apple: Scab (Venturia inaequalis) and powdery mildew.
Application timing, dilution, and safety directions
Apply Contaf Plus preventively at the initial forecast of disease-conducive weather or upon observing the very first symptoms.
Ensure uniform canopy coverage using calibrated knapsack sprayers operated at container label recommended dilution rates.
- Spraying technique: Thoroughly wet foliage and stems, ensuring penetration into lower canopy layers.
- Resistance management: Alternate with multi-site contact protectants like Mancozeb to prevent pathogen resistance.
- Protective measures: Wear protective clothing, chemical-resistant gloves, and face shield; respect statutory pre-harvest intervals.
