Active ingredient and biochemical mode of action
Carbendazim interferes with fungal cell division by binding specifically to beta-tubulin subunits, inhibiting microtubule assembly during mitosis. It is rapidly absorbed by plant roots and green foliage and moves acropetally through the xylem, protecting untreated new growth.
- Active ingredient: Carbendazim 50% WP (wettable powder)
- Chemical group: Benzimidazole systemic fungicide (FRAC code 1)
- Mechanism of action: Mitotic spindle inhibitor disrupting beta-tubulin polymerization
Registered crop diseases and applications
- Seed treatment: Dry dressing or wet slurry treatment for wheat, paddy, pulses, and groundnut to control seed-borne loose smut, blast, and collar rot.
- Soil drenching: Applied to nursery beds and root zones to manage damping-off and root rot in vegetables and fruit seedlings.
- Foliar spray: Controls anthracnose, powdery mildew, Tikka leaf spot in groundnut, and blast in rice.
Safety handling and resistance management
Repeated exclusive use of benzimidazole fungicides can induce fungal resistance. Farmers should rotate carbendazim with fungicides having distinct modes of action (such as strobilurins, triazoles, or contact protectants like mancozeb). Strictly adhere to CIBRC approved label dosages, wear protective clothing, and follow recommended safety intervals.

Common questions
What is the active ingredient in Bavistin?
The active ingredient is carbendazim 50% WP, a systemic benzimidazole fungicide.
How is Bavistin used for seed treatment?
It is mixed dry or as a slurry with seeds at label-recommended rates before sowing to protect emerging seedlings from seed-borne fungal diseases.
Why is alternating fungicides recommended to prevent resistance?
Repeated use of single-site fungicides like carbendazim can cause fungal strains to develop resistance, which alternation prevents.
