Taqat Fungicide (Captan + Hexaconazole): Diseases and Uses

Taqat is a combination fungicide manufactured by Tata Rallis containing Captan 70% and Hexaconazole 5% WP. It provides dual-action contact and systemic defense against powdery mildew, anthracnose, leaf spots, and scab across chillies, apples, grapes, and vegetables under CIBRC standards.

Last reviewed: 10 November 2026

Synergistic Systemic and Contact Mode of Action

Taqat combines Hexaconazole (a systemic triazole, FRAC Group 3) with Captan (a multi-site protectant phthalimide, FRAC Group M04). Hexaconazole translocates through plant xylem to inhibit fungal ergosterol biosynthesis from within, while Captan forms a multi-site protective shield on leaf and fruit surfaces.

This synergistic pairing provides strong curative suppression of established fungal hyphae alongside preventative barriers against new spore germination.

  • Chilli: Anthracnose fruit rot (dieback) and powdery mildew.
  • Apple: Apple scab (Venturia inaequalis) and powdery mildew.
  • Grapevines: Powdery mildew and anthracnose.
  • Vegetables: Early blight and leaf spots in tomatoes and potatoes.
  • Resistance management: The multi-site Captan component prevents pathogens from developing resistance against systemic triazoles.

Spray Timing and Application Guidelines

For optimum crop protection, apply Taqat preventatively at the earliest visual symptom appearance or during favorable weather for disease development.

Ensuring uniform canopy wetting provides complete contact and systemic uptake.

  • Mix the wettable powder thoroughly in clean water to ensure a homogenous, lump-free spray suspension.
  • Apply using calibrated knapsack sprayers fitted with hollow cone nozzles during calm morning hours.
  • Observe label pre-harvest intervals and wear personal protective equipment during handling.

Common questions

What active ingredients make up Tata Taqat fungicide?

Taqat contains Captan 70% (a contact protectant) + Hexaconazole 5% WP (a systemic triazole).

How does Taqat control anthracnose fruit rot in chillies?

Hexaconazole moves systemically to halt fungal growth inside tissues, while Captan protects developing fruitlets against new spore germination.

Does Taqat offer both preventative and curative control?

Yes, Captan provides surface preventative protection while Hexaconazole provides curative eradication of established early infections.
