The main principle of the method is: the food of insects will be covered with a layer of dust, and they will have nothing to eat. After a while, they will start to die. With this method, plants can be treated in open areas and in greenhouses.

Spray Decoction and Infusion

To prepare the decoction,

  1. Mix half a cup of tobacco dust in 1 liter of water and boil for about half an hour.
  2. Add water to the initial level during evaporation.
  3. Leave the broth in a dark place for a day.
  4. Filter the solution and add 2 liters of water.
  5. Mix a small piece of soap (10-15 g) or 1 -2 tablespoon of liquid soap. You can also add onion peel or garlic cloves in the solution.

Spray the plants with a ready solution. The event takes place 2-3 times every 7-10 days. Spray the solution on fruit trees less than 2 weeks before harvest.

The infusion of tobacco is very similar to a decoction. You need 2-3 days to make an infusion. To prepare the infusion-

  1. Take 1/2 cup of tobacco dust and pour in 1 liter of hot water.
  2. Infuse the solution for 24 hours and stir it periodically.
  3. Filter the infused solution.
  4. Add 1-2 liters of water and a piece of soap or 1-2 tablespoon liquid soap.
  5. Pour the solution in a spray bottle and use it immediately after preparation.

Another Recipe:

To make infusion-

  1. Take a cup of wood ash and a cup of tobacco dust and pour it in 1 liter of hot water.

  3. Filter the resulting infusion and pour it into a bucket, add water to the full extent.
  4. Add 2 tablespoons of liquid soap. Stir and spray the garden thoroughly.


This method is suitable for pest control of fruit trees. Fumigation should apply only after the flowering period is over. If you are fumigating in the flowering stage, it can scare the bees and other pollinating insects that prevent pollination. In addition, it is important to guess the direction of the wind: the bottom line is that the tobacco smoke does not go to the house or the neighbors.
