Fungicides
Propiconazole
Propiconazole inhibits the demethylase enzyme, thereby blocking ergosterol biosynthesis in fungi. This inhibition prevents the formation of fungal cell membranes, leading to cessation of fungal growth.
Propiconazole 25% EC
(Emulsifiable Concentrate)
Systemic Fungicide with Protective and Curative Action
Trade Name: Tilt
Chemical Group: Triazole
Mode of Action:
Propiconazole inhibits the demethylase enzyme, thereby blocking ergosterol biosynthesis in fungi. This inhibition prevents the formation of fungal cell membranes, leading to cessation of fungal growth.
It exhibits systemic movement within the plant — translocating upward (acropetal) through the xylem from roots to leaves and vice versa.
Application Management:
- Systemic fungicide with both protective and curative properties.
- Recommended for preventive application or at the early stages of infection for best efficacy.
Recommended Crops, Target Diseases, and Application Rates:
| Crop | Disease | Rate and Timing of Application |

| Rice | Sheath Blight | 1 L/ha as foliar spray (apply when ~30% of rice stems show infection) |
| Wheat | Rust | 1 L/ha |
| Wheat | Fusarium Head Blight | 1 L/ha — at least one foliar spray at the flowering stage; repeat after 7 days if necessary |
