Description
Agniastra (“fire weapon”) is one of the stronger natural-farming protection sprays. It is traditionally used when borers — stem borers, pod borers, fruit borers — are attacking a crop, usually after gentler sprays like Neemastra.
We don’t sell Agniastra. It is made by boiling locally available ingredients and we recommend preparing it on your farm. Because it is strong, it’s worth learning in person the first time — request a farm visit.
Ingredients (for 1 acre)
| Desi cow urine | 20 litres |
| Neem leaves, crushed to a pulp | 5 kg |
| Tobacco (powder or leaf) | 1 kg |
| Hot green chilli, ground | 500 g |
| Local garlic, ground | 500 g |
How to prepare
- Put everything into a metal vessel and mix.
- Bring to the boil and let it rise five times (bring to boil, let it settle, repeat), then take off the heat.
- Cover and leave to cool and steep for about 48 hours, stirring twice a day.
- Filter through a fine cloth.
How to use
- Dilute about 6–8 litres of Agniastra in 200 litres of water for 1 acre.
- Spray only when borers are present, not as a routine.
Storage & shelf life
Traditionally kept up to about 3 months in a closed container in the shade.
Good practice & safety
- Tobacco, chilli and garlic are strong irritants. Boil outdoors, wear gloves, a mask and eye protection, and keep children and animals away.
- Always dilute. Never spray neat, and never on young seedlings.
- Leave a gap of at least a week between the last spray and harvest, and wash produce.
- Test on a few plants first.
