Saaf Fungicide: Carbendazim + Mancozeb Active, Uses, and Safety

Saaf is a proven combination fungicide containing Carbendazim 12% and Mancozeb 63% WP. It provides dual-action systemic and contact protection against a wide spectrum of seed-borne, soil-borne, and foliar fungal diseases in field and horticultural crops.

Last reviewed: 10 November 2026

Dual Fungicidal Chemistry and Spectrum

Saaf combines Carbendazim (a systemic benzimidazole, FRAC Group 1) with Mancozeb (a broad-spectrum contact dithiocarbamate, FRAC Group M03). Carbendazim translocates through plant tissues to disrupt fungal tubulin assembly, while Mancozeb forms a multi-site protective barrier on leaf surfaces that prevents new spore germination.

This synergistic interaction broadens disease coverage while reducing the likelihood of pathogen resistance.

  • Groundnut: Tikka disease (early and late leaf spots) and collar rot.
  • Paddy: Blast (Magnaporthe oryzae) and sheath blight.
  • Chilli: Anthracnose fruit rot and dieback.
  • Potato and tomato: Early blight and damping off in seedlings.

Application Methods and Seed Treatment

Saaf is versatile and registered for dry seed dressing, wet slurry treatment, seedling root dip, and foliar spraying.

Treating seeds before sowing creates a sanitized rhizosphere zone that prevents early fungal damping off.

  • Seed treatment: Mix recommended dry powder per kilogram of certified seed to eliminate surface and internal fungal pathogens before sowing.
  • Foliar spray: Apply preventatively or at initial symptom appearance using thoroughly agitated spray solutions.
  • Safety and storage: Wear protective gloves and a dust mask when handling the dry powder, and store securely away from food and water sources.
