The warm and humid environment of polycarbonate greenhouses provides ideal conditions for the proliferation of microorganisms, bacteria and insects. To prevent crop contamination, shelters must be regularly disinfected. A safe treatment method is fumigation with tobacco smoke. The polycarbonate tobacco stick for the greenhouse is reliable and safe. The coating and frame will not be damaged by it, because the active ingredient is nicotine.
Advantages of using tobacco shanks for greenhouses
The main advantages of tobacco checkers are:
- ease of use;
- they destroy diseases and pests without harming the crops planted in the greenhouse;
- tobacco smoke repels rodents and bees;
- the smoke screen completely disinfects the greenhouse, penetrating even hard-to-reach places;
- The highly concentrated carbon dioxide released during smoldering is an excellent natural preservative, it improves plant photosynthesis, accelerates the period of fruit ripening, and the green mass becomes thicker, juicier and fleshier;
- tobacco sticks do not contain chemicals, their action is based on the destructive effect of nicotine on parasites;
- Fumigation can be used to treat any size area.
In what cases is the treatment of greenhouses with a smoke bomb used?
Treatment with smoke products is carried out if the vegetables in the greenhouse grow and develop poorly, and their leaves are affected by pests and diseases. This is especially true for greenhouses made of polycarbonate, the air humidity inside of which is greatly increased, which leads to the proliferation of bacteria and parasites.
Fumigation with smoke bombs effectively destroys:
- aphids;
- copperhead;
- spider mite;
- ground fleas;
- Whitefly butterfly;
- thrips;
- late blight.
Tobacco sticks can be used to prevent plant damage, as a routine disinfection of greenhouses, to stimulate the growth of vegetable crops, and to increase the safety of fruits. The nicotine they contain is absolutely harmless to plants, and in some crops, for example, potatoes, eggplants, peppers and tomatoes, it is contained in small quantities.
Varieties of tobacco smoke bomb
Tobacco checkers are presented in several types:
- Hephaestus;
- Volcano;
- Late blight.
All of them effectively destroy pests and infectious diseases in greenhouses, and at the same time are harmless, unlike sulfur bombs (“Fas”).
Hephaestus
The Hephaestus tobacco checker consists of tobacco crumbs and an incendiary mixture. The packaging has a cylindrical shape and is available in weights of 160 or 250 g. Effectively fights against many types of pests: spider mites, copperheads, aphids. Stimulates active plant growth. When opened, it quickly loses its properties. It is advisable to store unused products away from flammable substances, in a dry room at +20÷25ºС. To fumigate a greenhouse with an area of 25 m², one piece is enough.
Late blight
Tobacco smoke bomb "Late blight" is designed to combat fungal diseases: powdery mildew, late blight, rust and other types of fungi. In addition to tobacco crumbs, an igniter and a combustion stabilizer, it contains an increased amount of sodium bicarbonate, which completely destroys the fungal microflora. The product has the shape of a cylinder, weighing 220 g, one piece is enough to treat an area of 35 m². Repeated fumigation of the greenhouse with a tobacco stick “Fitblight” is carried out after 48 hours. If the packaging of the product is broken, it self-destructs.
Volcano
Tobacco checker "Vulcan" is effective in the fight against late blight and all known pests of garden crops, and has many positive reviews. The cylindrical product consists of tobacco dust, ignition mixture and cardboard membranes. To treat a greenhouse to stimulate crop growth, you will need 1 tube per 50 m², and to kill insects, one tube is used per 30 m². The substances are not addictive to insects.
How to use a checker in a greenhouse
Before fumigation with a smoke bomb, the greenhouse must be thoroughly cleaned, getting rid of all possible carriers of diseases and insects.
- Clear the top layer of soil, removing leaves and dead plant bushes.
- Disassemble the racks.
- Take out all unnecessary items: boxes, pallets, containers with water.
- Wash the greenhouse covering with soap and water, paying special attention to joints and seams where insect larvae and microorganisms may be located.
- Loosen the soil to facilitate the penetration of combustion products into it. Mold, parasites and their eggs in the soil will die.
- Seal the greenhouse. Seal all gaps and cracks in doors, windows and joints.
- Lightly moisten the walls and soil. A smoke bomb smolders better in a humid environment.
- Evenly arrange stands of bricks or unnecessary metal utensils. If one checker is used, then it must be installed in the center.
The calculation of the required number of tobacco sticks is made based on the area of the greenhouse and the degree of its damage.
When to burn a saber in a greenhouse
Greenhouses must be disinfected in spring and autumn. To get rid of all damaging factors, and not to be afraid that the planted plants will become infected, the procedure is carried out for 2-3 days in a row. In the spring, smoke treatment of the greenhouse with a tobacco bomb should be carried out three weeks before planting vegetable crops, and in the fall - after harvesting. After the procedure, the room is ventilated and closed until spring.
Checkers can also be used during periods of active growth. There is no need to remove vegetables from the greenhouse; tobacco smoke will not harm either the plant or the fruit.
How to light a saber in a greenhouse
It is necessary to light a tobacco smoke bomb outdoors. Having placed it on a pedestal of bricks, they light the wick and step back a little so that the flaring flame does not touch the clothes. After 20 seconds, the fire will go out and intense smoldering will begin.
This means that you can bring it into the greenhouse. Having laid out the checkers around the perimeter of the room, you should leave, closing the door tightly. The smoking will last for several hours. After fumigation, the room is ventilated and a few days later the procedure is repeated.
Reviews of people who use Hephaestus, Phytophthora or Vulcan tobacco sticks claim that after the 1st treatment only insects die, and after the 2nd fumigation, the larvae, which have already become adults, also die. Smoke has no effect on eggs.
Security measures
A tobacco smoke bomb will not cause harm to humans, plants, or polycarbonate coating, but when fumigating a greenhouse, simple safety precautions must be observed:
- If several smoke products are used, to prevent tobacco smoke from corroding the mucous membrane of the eyes, it is recommended to wear safety glasses before the procedure.
- Long sleeves will protect exposed areas of the body from hot smoke.
- When placing checkers, you must hold your breath or wear a mask.
- Ensure the room is airtight to prevent smoke from escaping.
- Do not be in the greenhouse during fumigation.
- Do not enter it earlier than a few hours after the checker has finished smoldering. The carbon monoxide should dissipate.
Work in a greenhouse after using a smoke bomb
After using the Hephaestus, Vulcan, and Phytophthora smoke tobacco bombs, no special work is required.It is necessary to thoroughly ventilate the room until carbon monoxide and the smell of smoke have completely disappeared, after which you can begin daily work in it. If you need to enter the greenhouse a little before the smoke clears, it is recommended to use a protective mask.
Conclusion
Tobacco block for greenhouses made of polycarbonate can be used throughout the season. It does not contain chemicals, is easy to use, and effectively destroys diseases and insects that cause damage to vegetable crops. We must not forget that smoke products require caution and all actions must be performed strictly according to the instructions.
