Introduction
UPL Saaf Fungicide is a well-established and widely trusted fungicide known for its dual mode of action—systemic and contact protection. It combines Mancozeb 63% and Carbendazim 12% WP, making it highly effective against a broad spectrum of fungal diseases in crops.
Due to its acropetal movement through the xylem vessels, it offers long-lasting protection from fungal infections. Saaf is extensively used for foliar sprays and seed treatment, ensuring robust disease management.
In this comprehensive guide, we will explore its mode of action, effectiveness, recommended crops, targeted pathogens, technical specifications, and frequently asked questions to help farmers make an informed decision.

Saaf fungicide composition:
Carbendazim (12%) + Mancozeb (63%)
Mode of Action
UPL Saaf Fungicide operates through a dual mode of action—systemic and contact:
- Carbendazim (12%): A systemic fungicide that penetrates the plant tissue and moves intercellularly through the xylem. It inhibits β-tubulin synthesis, effectively stopping fungal growth at the cellular level. This provides curative and residual protection.
- Mancozeb (63%): A multi-site contact fungicide that disrupts essential enzymatic functions in fungal cells, leading to their destruction. It forms a protective barrier on plant surfaces, preventing fungal spores from germinating.
Together, these ingredients prevent, cure, and protect against fungal infections, ensuring healthier crops and higher yields.
Effectiveness of UPL Saaf Fungicide
The combination of Mancozeb and Carbendazim makes Saaf an exceptionally effective fungicide due to its broad-spectrum activity:
Key Benefits
- Dual protection: Provides both systemic (internal) and contact (external) defence against fungal infections.
- Acropetal movement: Carbendazim is absorbed by the plant and moves upward through the sap stream, ensuring total protection.
- Long-lasting residual effect: Continues to work even after application, reducing the need for frequent spraying.
- Resistance management: Effective against fungal resistance due to its multi-site action.
- Safe and cost-effective: Proven for consistent results while being economical for farmers.

Saaf fungicide: How to use
UPL Saaf Fungicide is a dual-action fungicide that provides systemic and contact protection against fungal diseases in crops. Here’s how to use it effectively:
Application Method
- Foliar Spray:
- Mix 2-3 grams of Saaf per litre of water.
- Stir well to ensure proper dissolution.
- Spray evenly on affected plants, covering both upper and lower leaf surfaces.
- Apply every 10-15 days or as soon as the first signs of fungal infection appear.
- Seed Treatment:
- Mix 2 grams of Saaf per kg of seeds.
- Thoroughly coat seeds before planting to prevent early-stage fungal infections.
- Soil Drenching (for root diseases):
- Mix the recommended dosage in water and apply directly to the soil around the plant base.
Precautions
- Wear protective gloves and masks while handling.
- Avoid spraying during high temperatures or strong winds.
- Maintain a pre-harvest interval of 7-14 days to minimise residue levels.
