The alkaloid nicotine, which is found in large quantities in the leaves and stems of tobacco, is a poison for many insects, working in the composition of plants as their natural defender against pests. And gardeners know this for a long time.
As far back as the 17th century, nicotine extracted from tobacco was already used as an insecticide, and a century later the plants affected by insects began to be treated with tobacco smoke. Why do not you try to use this cheap and effective means to combat garden and garden pests?
Moreover, tobacco is not only an effective insecticide, but also a real fertilizer - in addition to alkaloids, it contains many useful organic and mineral substances that can enrich the soil.
How to use tobacco in the garden and garden? There are several methods.
Dusting plants and soil with tobacco dust
The easiest and simplest, but, nevertheless, an effective way to combat insect pests on the site - dusting the plants themselves and the soil around the tobacco dust. You can make this dust yourself if you grow tobacco - the collected leaves just need to be dried and crushed. But it is easier and faster to buy the drug in a specialty store. At the same time, you can use both clean tobacco dust and its various mixtures (Tabazol is a mixture of tobacco with ashes, Tabagor is a mixture of tobacco with mustard, etc.), which will act not only as an insecticide, but also as fertilizer for soil.
Although all of these mixtures are harmless to humans and animals, fine, sharp-smelling dust can cause allergic reactions, especially getting on the mucous membranes. Therefore, spray it in a dry form or spray in solutions should be in closed clothes, gloves and a respirator.
The maximum effect of dusting tobacco is observed when growing crops of the cruciferous family, affected by cruciferous flea and cabbage fly. To combat these insects, beds with cabbage (radish, turnip, radish, etc.) are simply powdered with tobacco dust at the rate of 20 g per 1 sq. M - it is possible in its pure form, with various additives like ash, hydrated lime, and pepper powder, etc. Especially this treatment is useful for plants at the stage of cotyledons and the first tender leaves.

Tobacco dust to grown plants will help get rid of such misfortunes as slugs. Just make the grooves with honey in rows of plantings and put tobacco dust in them. Through such a "drying moat," the slug will not get over without harming itself.
Also, do not like dusting plants with tobacco caterpillars, cabbage butterfly, onion fly, onion hover, strawberry leaf beetle (processing is carried out only in early spring, because tobacco can worsen the taste of berries) and the raspberry beetle.

The dusting of the beds with tobacco dust is done in overcast windless weather, preferably in the evening. It is not recommended to carry out such treatment more than 2-3 times per season (this should be done at intervals of 1-2 weeks).
Spraying of plants with infusion and decoction of tobacco
To combat leaf-eating insects (aphid, thrips, listoblushki), caterpillars, spider mites, not dusting, but spraying the plants with decoction and tobacco-based infusions is better suited.
To prepare the infusion, dissolve 2 cups of tobacco dust in 10 liters of hot water and leave for 2 days, stirring occasionally. After a specified time, strain the solution and add 1 tbsp. liquid soap as adhesive. Such an infusion will be more effective with the addition of ash (1 cup per specified volume of solution).
To make tobacco broth, 1/2 cup of tobacco dust must be filled with 1 liter of water and boiled for half an hour, adding water to the original level. The broth must be insisted for another day, and then filtered and diluted with water 1: 2. In order to better decorate the leaves on the leaves during spraying, you can add 10 g of soap to it.
Similar infusion or decoction, abundantly wetting the plants, can be processed:
- fruit trees after flowering, in order to protect them from sucklings, or no later than 2 weeks before harvest;
- garden plants against aphids - spraying them in the morning on the leaves 2-3 times per season with a difference of 7-10 days;
- indoor plants from spider mites - treated every 10 days, no more than 3 sprays are allowed;
- potato from the Colorado potato beetle - 2-3 times with an interval of 5-8 days.

Fumigation of plants with tobacco smoke
Fumigation with tobacco dust is another possible use of tobacco at the dacha for plant protection. For fumigation use special tobacco smoke bombs or simply burn small wood or bark in a metal container, where clean tobacco dust is poured from above.
Where and when can tobacco smoke be applied?
- In greenhouses and greenhouses - with the preventive purpose in empty structures for 2-3 days before the start of sowing or transplanting.
- In greenhouses and greenhouses, where crops are already growing - subject to the presence of a large number of pests.
- In vegetable stores, if mass reproduction of insects or mice is noticed.
- In the garden - fruit trees are fumigated with tobacco dust after flowering, so as not to scare away insect pollinators, but to cope with pests.
Indoors it is more appropriate to use not open fire, but smoke bombs, which slowly smolder with evolution of carbon dioxide, but without a significant increase in temperature. Processing time tobacco smoke is about 2-3 hours. For closed rooms, the calculation is 5 grams of tobacco dust (powder) per 1 cubic meter of space. Of course, when fumigating plants with smoke, you must use protective equipment and avoid being in a greenhouse (storage) at the very moment of fumigation.
Tobacco dust as a fertilizer
As we have already mentioned, tobacco dust, in addition to toxic substances, contains organic substances (proteins, carbohydrates, aroma oils) and minerals (nitrogen, calcium, potassium, phosphorus, magnesium, sulfur) that are useful for plants and soil. Therefore, it can be used in the garden as a fertilizer.
Tobacco dust is usually added to mineral fertilizers or used independently in the composition of the above mixtures with other beneficial substances (Tabazol, Tabagor, etc.).
Tobacco dust is usually applied as a fertilizer to a vegetable garden for digging up soil for seedlings or planting holes when planting tree saplings and shrubs. The application rate is 150-350 g / sq.m.
On weakly acid and alkaline soils, the rate of tobacco dust should be about half as much as on strongly acidic.
It is possible to use tobacco to enrich the soil with microelements and for transplanting houseplants - 1/2 tsp is added to 10 liters of soil. tobacco dust.
As you can see, tobacco dust is a wonderful tool in the arsenal of the gardener and gardener. It gives a quick and noticeable result in the fight against plant pests, is affordable and cheap, very easy to use in practice, harmless to the soil and people. Do you use this folk remedy on your site?
