Dual Chemical Chemistry and Mode of Action
Sporium unites a strobilurin QoI inhibitor (azoxystrobin) with a triazole DMI inhibitor (difenoconazole).
Azoxystrobin prevents fungal spore germination by blocking cellular respiration in mitochondria, while difenoconazole halts mycelial growth by disrupting ergosterol cell membrane synthesis.
- Azoxystrobin (Strobilurin): Systemic and translaminar protection preventing spore germination and appressorium formation
- Difenoconazole (Triazole): Fast xylem-mobile systemic action stopping established hyphal development inside leaf tissues
- Greening and Vigor: Promotes physiological canopy health, supporting prolonged photosynthesis during yield formation
Target Crops and Fungal Diseases
Sporium is formulated for commercial crops facing complex fungal blights and fruit rot pathogens.
In paddy, it is widely used to prevent sheath blight and neck blast, while in chilli it protects flowers and fruit pods from dieback.
- Chilli: Anthracnose fruit rot (dieback) and powdery mildew
- Paddy (Rice): Sheath blight, blast, and false smut prevention
- Tomato and Potato: Early blight and Septoria leaf spot
- Grapes and Cucurbits: Downy mildew and powdery mildew mitigation
Application Guidelines and Resistance Prevention
Spray preventively or at the first onset of visible fungal lesions, ensuring thorough coverage of the lower and middle foliage.
To safeguard strobilurin and triazole chemistries from fungal resistance, alternate with multi-site contact protectants like mancozeb.
- Water Volume: Use 200 liters of water per acre with fine hollow-cone nozzles for complete canopy coverage
- Weather Timing: Apply early in the morning after dew dries, or during calm late afternoons
- Pre-Harvest Interval: Review CIBRC label directions for official crop-specific withholding intervals

Common questions
What is the technical composition of Sporium fungicide?
Sporium combines azoxystrobin and difenoconazole, pairing strobilurin and triazole systemic chemistries.
Can Sporium be used on chilli for anthracnose?
Yes, azoxystrobin plus difenoconazole combinations are widely recommended for controlling anthracnose fruit rot and dieback in chilli.
Does Sporium have curative action?
Yes, the difenoconazole triazole component provides curative activity against early established fungal infections inside plant tissues.
