Gray checkers for greenhouses are an excellent tool for disinfection of interior space. A gray polycarbonate polisher is considered one of the most affordable and effective means for preventing plant diseases, as it allows you to quickly get rid of various pests and microorganisms. During disinfection, the air of the greenhouse room is dried, which further prevents the formation of mold and fungus. Fumigation should be carried out periodically, in addition to mandatory autumn treatments.
What is a sulfur checker for greenhouses and how does it work
A sulfur checker is available in the form of tablets containing the active substance - sulfur. The kit can contain from 5 to 10 tablets. In order to find out how much money is required for a certain area, you should calculate its volume. On average, 20 tablets of substance will be needed for 40 cubic meters.
Sulfur gum has acaricidal properties - it kills insects and mites, for a while it repels rodents
Useful properties of drafts:
- Efficacy against fungal organisms, insects and bacteria;
- Easy to use;
- Good penetrating power;
- Accessibility and economy.
It is possible to distinguish its toxicity from the minuses, so use requires care and strict compliance with the enclosed instructions.
The fact is that due to the interaction of smoke and water, an acid is formed, capable, besides pests, to kill the organisms necessary for soil fertility.
A gray checker does not apply if the frame of the hotbed is made of metal elements, since sulfurous anhydride is destructively affecting the metal. In addition, fumigation does not affect the deeper layers of the soil, and it can not be carried out at the beginning of sowing and during the entire growing season.
When the treatment is carried out frequently, the polycarbonate coating may lose its transparency and become cracked.
In which cases should the treatment of the greenhouse be selected with a sulfur checker
Different greenhouse premises have their problems, therefore fumigation can be carried out by different types of smoke.
A gray checker can be used in any greenhouse and greenhouse made of polycarbonate or with film and glass coating
In addition to sulfur bars, the following smoke sources exist:
- Permethrin-based guns used in the presence of ticks, aphids, And caterpillars - they can be used when disinfection is required during vegetation and even when the fruits are ripe;
- Preparations with bromide content, in addition to insects, are designed to combat rot and fungal infections;
- Hexachlorane agents are effective in combating worms and mites that feed on plants;
- Checkers with nicotine are used to get rid of caterpillars and butterflies, aphids and spider mite.
As for the preparation in which the active substance is sulfur, it is suitable not only for decontamination of the soil, but also for the structure itself. This is ideal for a greenhouse with a polycarbonate coating.
Sulfur grit is selected if there are microorganisms in the greenhouse such as mites, lice, as well as fleas and lice.
Well fumigated sulfur in the presence of woodworms. Also, the agent can be used for fungal infection and mold.
Tips for gardeners: when to process a greenhouse with a sulfur checker
Many greenhouse owners are wondering when it is better to make fumigation with a sulfur checker and how often it can be done.
When contaminating the soil, experts recommend using the greenhouse checker
The testimonials of experienced gardeners show that the optimal options are:
- Preventive treatment in the autumn;
- When there are many pathogens in the greenhouse, an additional procedure in the spring.
If necessary, work can be done in the summer. When the air of the greenhouse with polycarbonate coating is strongly moistened, there is always the risk of multiplying all kinds of bacteria. This, in turn, leads to the defeat of young immature plants with harmful viruses and parasites.
This situation can continue from year to year, as some of these organisms are extremely tenacious, so it is in autumn that the greenhouse should be treated with smoke.
Due to its high penetration, sulfur smoke can effectively disinfect large areas. In the spring, fumigation is repeated only for a very good reason.
How to use a sulfur checker in a greenhouse
Before, sanitizing, you should prepare the interior space of the greenhouse.
Tools from sulfur compounds are detrimental to harmful organisms
Instruction for use:
- Complete removal of all plants from beds, weeds are weeded out, all remains and tops are better burned;
- After that, the walls of the greenhouse are cleaned - for plain polycarbonate, you can use ordinary detergents and a soft sponge, dust and dirt on the frame parts are washed;
- The room must be tightly sealed before fumigation, otherwise the effectiveness of the sulfur checker will be significantly reduced;
- Since the smoke from sulfur smolder can penetrate only a small depth( 5 cm), it is desirable to loosen the soil well;
- If a sulfuric agent is used in a greenhouse with a metallic skeleton, it is necessary to apply to the structural elements of the solidol;
- For safety reasons, a protective suit, rubber gloves, and a gas mask or respiratory mask should be used before the procedure;
- For better results, the hothouse walls and soil are moistened with a hose;
- The checker with sulfur should be placed vertically on the refractory material, as it is used to heat up when smoldering;
- When the flame of the wick becomes stable, you must immediately leave the room, if necessary, pasting the existing gaps.
Decay lasts for 2-3 hours - it depends on the humidity of the air. Since the effect can last about 3 days, it is not necessary to enter the greenhouse at this time. After that, the building is ventilated and the polycarbonate and the frame structure are washed again.
Features of application of a sulfur checker in a greenhouse in the spring
When, for some reason, fumigation was not performed before winter, and also in case of severe soil contamination, the sulfur check is used in the early spring. Usually this is done in late March or early April, just after the last snow comes down.
For the sanitation of the greenhouse, different drafts are selected depending on the purpose of use.
Basic rules for preparing the room:
- All collected garbage and tops must be burned;
- In the treatment of the coating and the frame, a soap solution is used, if the crops were subject to diseases last season, antibacterial agents should be added;
- Shelving and tools from polymeric materials should be bleached, formaldehyde or ordinary boiling water;
- Details of wood can be treated with a calcareous test.
In the rest of the spring, the process of using sulfur smoke is no different from autumn disinfection.

As the polycarbonate greenhouse provides high humidity inside the greenhouse space, this leads to the appearance of many pathogenic microorganisms. Therefore, the annual fumigation procedure with different smoke means is necessary. When decontaminating, it is important to follow the instructions and observe all the safety rules to avoid damage to your health.
