What it is

Bio-repellent (bio-insecticide) is an organic ferment used to control crop pests — caterpillars, piercing and sucking insects, coffee berry borer, scale insects and more — and to protect plants from fungal diseases. Its power comes from the strong smell and taste of garlic, chilli, onion and ginger, sharpened by vinegar and alcohol and fermented with Mountain Microorganisms.

On the Nutritive Cycle: This is an all-stages protective input. It doesn't feed a growth stage — it defends the crop, raising resistance to pests and diseases whenever they appear.

When to use it

  • After germination — begin applying once seedlings are up.
  • On attack — spray again each time you see pests attacking your crops.
  • Dosage250 cc in a 20 L spray pump, sprayed on affected crops.
  • Also — repels ecto-parasites on animals.

Signs it worked / troubleshooting

  • Good: a sharp, pungent smell and taste — that bite is the repellent action.
  • ⚠️ Weak or flat smell = under-fermented → give it the full 15 days sealed.
  • 🚫 Rotten off-smell rather than pungent = air got in → keep it airtight next batch.

How to store

Kept sealed and stored well, the bio-repellent lasts up to 1 year. Keep it cool, dry and out of direct sun.
