Active chemical nature and systemic mode of action
Folicur contains Tebuconazole 25.9% EC, a potent systemic compound belonging to the triazole (demethylation inhibitor / DMI) chemical class.
It works by inhibiting the biosynthesis of ergosterol, a vital component of fungal cell membranes. Deprived of ergosterol, the fungal pathogen cannot maintain cell wall integrity, halting fungal hyphal growth, haustoria function, and spore formation.
- Active chemical: Tebuconazole 25.9% EC (emulsifiable concentrate).
- FRAC classification: Group 3 (Sterol biosynthesis inhibitor).
- Acropetal translocation: Rapidly absorbed by foliage and moved upward through xylem tissues to protect emerging leaves and shoots.
Target crops and approved fungal disease spectrum
Bayer Folicur is registered across major cereal crops, commercial oilseeds, spices, and fruit orchards in India.
It is celebrated for controlling sheath blight and blast in rice, yellow rust in wheat, and powdery mildew across diverse crops.
- Paddy (Rice): Sheath blight (Rhizoctonia solani) and blast management.
- Wheat: Yellow rust (Puccinia striiformis) and brown rust.
- Chilli: Powdery mildew and fruit rot / anthracnose.
- Groundnut: Tikka leaf spot and rust.
- Onion & Garlic: Purple blotch (Alternaria porri).
Application timing, spray techniques, and safety
Apply Folicur preventively upon early forecast of cool, humid weather or at the very first visual appearance of fungal lesions.
Ensure uniform foliar coverage using hollow cone or flat fan spray nozzles, strictly following container label dosage recommendations.
- Spraying technique: Thoroughly wet the entire plant canopy, ensuring penetration into lower rice sheaths.
- Resistance management: Alternate with non-triazole contact fungicides (such as Mancozeb or Copper) to avoid pathogen resistance.
- Protective measures: Wear protective overalls, chemical-resistant gloves, and face shield; respect prescribed pre-harvest intervals.
