Bavistin

• Verified active ingredient: Carbendazim 50% WP is a registered Indian fungicide formulation.
• Systemic action: the active ingredient acts within treated plant tissue against susceptible fungal pathogens.
• Multiple application roles: the current Indian record includes area-based sprays, tree-specific treatments and wet-slurry seed treatments.
• Clear mode-of-action identity: FRAC classifies Carbendazim in Group 1, allowing it to be distinguished from genuine different-group rotation products.
• Resistance-aware positioning: FRAC rates MBC fungicides as high risk for resistance, so repeated Group 1 use should be avoided.

1. Systemic uptake: the fungicide is taken into treated plant tissue when applied according to the label.
2. Tubulin disruption: Carbendazim interferes with beta-tubulin polymerisation and normal microtubule formation.
3. Cell-division inhibition: susceptible fungi cannot complete normal mitosis, limiting continued germ-tube elongation and infection growth.

FRAC notes that resistance is common in many fungal species and that Group 1 members generally show positive cross-resistance. Another Carbendazim, Benomyl, Thiabendazole or Thiophanate-methyl product must not be presented as a different-mode resistance rotation.

The government table also contains an “aerial phase” entry and tapioca and chilli rows whose extracted crop/disease, dose or water-volume presentation is ambiguous. They are intentionally omitted here until the current physical Bavistin label is inspected. A dash in the government PHI column is not permission to harvest immediately; check and follow the current pack.

• Confirm the exact crop, disease, rate, water volume, method and any local restriction on the current physical Bavistin label before use.
• For a wet-slurry seed-treatment row, measure both product and water for the stated seed weight. Coat the seed uniformly and follow the pack's drying, handling and sowing directions.
• For a spray row, measure the treated area and use the listed total water volume. Do not turn an area rate into a universal grams-per-litre rate.
• This page makes no tank-mix or simultaneous-use recommendation. Apply Bavistin only as its own label directs.
• Wear the gloves, protective clothing, eye protection and respiratory protection specified on the current Bavistin label; avoid skin and eye contact and avoid breathing dust or spray mist.
• If the crop is intended for export, confirm the destination-market residue requirements and the buyer's crop protocol before use; an Indian registration does not by itself guarantee compliance with another market's MRLs.
• Keep the product away from food, feed, children and animals. Prevent spray, wash water and packaging from reaching ponds, drains or aquaculture.
• Store locked in the original labelled container in a cool, dry and ventilated place. Follow the current pack for first aid, disposal and medical guidance.

FRAC classifies Carbendazim as a high-resistance-risk Group 1 fungicide. Avoid repeated Group 1 treatments. Where another treatment is necessary, choose a separately applied product from a genuinely different FRAC group only when its current Indian label covers the same crop and disease. Follow the dose, PHI, timing and maximum-use restrictions of each product independently.

Always read and follow the current Crystal Bavistin label and leaflet. The physical pack is the final authority for approved crops and diseases, dose, water volume, timing, repeat-use limits, PHI, re-entry, PPE, first aid, environmental precautions, storage and disposal. This verified guide does not replace the label, local regulation or qualified agronomic advice.
