Chemical Class and Demethylation Inhibitor Mechanism
Tilt features the active ingredient Propiconazole 25% EC, belonging to the triazole chemical group. It functions as a Demethylation Inhibitor (DMI) by targeting the C-14 demethylase enzyme involved in fungal ergosterol biosynthesis.
Without ergosterol, fungal cell membranes lose structural integrity and leak vital contents, halting mycelial growth, haustoria formation, and secondary spore propagation within plant tissue.
- Active ingredient: Propiconazole 25 percent w/w EC
- Fungicide group: FRAC Group 3 (Sterol Biosynthesis Inhibitors - DMI)
- Systemic mobility: Rapid acropetal translocation via xylem conduits
- Activity spectrum: Broad-spectrum protective, curative, and eradicative control
CIBRC Approved Target Diseases and Crops
CIBRC registers Propiconazole 25% EC for high-pressure foliar and stem diseases across cereal crops, oilseeds, and orchard plantations.
Timely application at early infection onset halts latent mycelial development, preserving functional leaf area during grain filling and flowering stages.
- Wheat: Stripe / yellow rust (*Puccinia striiformis*) and leaf rust (*Puccinia triticina*)
- Paddy / Rice: Sheath blight (*Rhizoctonia solani*) and false smut (*Ustilaginoidea virens*)
- Groundnut: Early and late leaf spots (*Cercospora arachidicola* / *Phaeoisariopsis personata*)
- Tea: Blister blight (*Exobasidium vexans*) in plantation bushes
Application Guidelines, Timing, and Safety
Tilt delivers optimal disease suppression when applied preventively or upon early appearance of disease lesions. Ensure calibrated spray water volumes for uniform leaf and sheath coverage.
To prevent fungal resistance, avoid consecutive repeat applications of single-site DMI fungicides; rotate or tank-mix with multi-site contact protectants like Mancozeb or Chlorothalonil.
- Application timing: First spray at disease onset or flag leaf stage in cereals
- Anti-resistance strategy: Rotate with FRAC multi-site protectants (Group M)
- Water volume: 500 liters per hectare for knapsack sprayers on field crops
- Personal protection: Wear nitrile gloves, safety goggles, and protective apparel

Common questions
How does Propiconazole protect wheat crops from yellow rust?
Propiconazole penetrates wheat foliage rapidly and translocates upward, inhibiting ergosterol production in fungal rust spores and stopping mycelial development.
Is Tilt rainfast after application?
Yes, because Propiconazole is absorbed into plant vascular tissues within 1 to 2 hours after spraying, it exhibits excellent rainfastness under moderate weather conditions.
Can Tilt be applied preventively before disease symptoms appear?
Yes, preventive sprays prior to disease flare-up provide a systemic protective barrier that inhibits initial spore penetration and fungal infection.
