Tobacco contains nicotine, which is a very toxic organic poison. Leaves and stems of the tobacco plant are used to prepare extracts which can be applied to control aphids, caterpillars, thrips, leaf miners and mites.
The materials required for preparing 6 liters of the solution aretobacco100 gram, bar soap 24 gram and water6 litre.
Soak 100 gram of tobacco in 900 ml of water for 24 hours. Then squeeze the tobacco and remove all debris by filtering the extract through a muslin cloth or a strainer. Slice 24 g of bar soap into thin flakes and dissolve in 100 ml of water in another vessel.
Instead of bar soap six packet of shampoo sachet can also be used. Pour the soap solution into the tobacco decoction under violent agitation. Dilute this stock solution by adding 6 litres of water. This will give 7 litres of tobacco decoction and use the preparation immediately.
Maintain a waiting period of at least 4 days, before harvesting products that were sprayed with tobacco extracts.
