Active chemistry and biochemical mode of action
- Active ingredient: Hexaconazole 5% SC (suspension concentrate formulation, FRAC Group 3 / DMI).
- Mode of action: Demethylation inhibitor (DMI) that halts ergosterol biosynthesis, causing fungal cell wall disruption.
- Systemic mobility: Exhibits acropetal xylem translocation, protecting newly emerging leaves and tillers.
- Formulation advantages: SC formulation provides smooth dilution in water, lower worker toxicity, and superior foliage adherence.
Approved crop spectrum and fungal disease control
- Rice (Paddy): Highly effective for the control of sheath blight caused by Rhizoctonia solani.
- Chilli: Controls powdery mildew (Leveillula taurica) and fruit rot / anthracnose (Colletotrichum capsici).
- Groundnut: Manages early and late leaf spot (Tikka disease) caused by Cercospora species.
- Mango & Grapes: Controls powdery mildew (Oidium mangiferae / Uncinula necator).
- Apple: Effective against apple scab (Venturia inaequalis).
Application timing and resistance management
- Application window: Spray at the first appearance of disease symptoms or during disease-favorable humid weather.
- Spray equipment: Use knapsack or motorized mist blowers with hollow cone nozzles to achieve uniform foliar coverage.
- Resistance management: Rotate with non-triazole contact fungicides like Mancozeb or Chlorothalonil to prevent fungal resistance.
- Waiting period: Respect the CIB&RC approved pre-harvest interval (PHI) before harvesting edible produce.

Common questions
What is Hexaconazole 5% SC used for?
It is a systemic triazole fungicide used to control sheath blight in paddy, powdery mildew in chilli and grapes, and tikka disease in groundnut.
What is the mode of action of Hexaconazole?
It inhibits ergosterol biosynthesis in fungal cell membranes, stopping fungal growth curatively and preventively.
Can Hexaconazole 5% SC be mixed with insecticides?
It is generally compatible with common non-alkaline insecticides, but a jar test is recommended before tank mixing.
What does SC stand for in Hexaconazole 5% SC?
SC stands for Suspension Concentrate, which is a liquid dispersion of fine active particles in water.
