Sulfur checker for polycarbonate greenhouse: processing instructions

Greenhouse conditions become ideal not only for the development of plants planted in the ground, but also for various infections. Disinfection of greenhouses and greenhouses helps to reduce the likelihood of the spread of diseases. Consider the benefits and possible harm of a sulfur bomb for a polycarbonate greenhouse, the principle of its operation, the terms of use in spring and autumn, the rules for use and safety.

The benefits and harms of sulfur bombs for greenhouses

What does the processing of a polycarbonate greenhouse give:

disinfection of walls and ceiling, structure foundation, soil surface;
smoke penetrates into all cracks, that is, into all hard-to-reach places where liquid solutions cannot get;
1-2 treatments will be required for complete disinfection.

The tool also has disadvantages:

Smoke from a sulfur bomb is toxic, without observing safety precautions it can cause poisoning;
greenhouse material becomes cloudy after many treatments, small cracks appear on it;
metal structures are damaged;
sulphurous acid, one of the constituents of smoke, destroys all bacteria, not only harmful ones, negatively affects the soil.

Fumigation of a polycarbonate greenhouse cannot be carried out shortly before planting plants in it, which limits the period of use of the sulfur bomb.

Working mechanism

Sulfur balls are produced in the form of tablets (5-10 pcs in a pack).), which contain 750 g of active ingredient per kg of product. After ignition, they begin to smolder and give off smoke, which contains sulfurous anhydrite and sulfurous acid. Poisons kill microorganisms and pests, repel rodents.

Smoke envelops the walls of the room, internal structures, disinfecting them. After processing, pests, bacteria, viruses die even in the most inaccessible places. That is, complete disinfection of the premises is obtained, unattainable with the help of other chemicals.

Terms of application and instructions for use

The greenhouse is treated with sulfur 1 or 2 times a year, at the beginning or end of the growing season - in spring or autumn, that is, when there are no plants in it. It is unacceptable to fumigate when seedlings or seeds have already been planted or during the growing season. Sulfur can burn the leaves, plants will be lost.

Fumigation is carried out in an empty greenhouse, without strangers. Before starting work, it must be prepared: remove all unnecessary that may interfere with the free spread of smoke. Close all cracks from where smoke can seep into the street. Lightly dampen the polycarbonate surface with water.

Put a checker in the middle of the greenhouse or place several at an equal distance from each other on a hard surface: brick, cinder block, metal plate. For ignition, use paper, a wick. Kerosene and explosive gasoline are prohibited. After igniting, exit the greenhouse and close the door tightly. Staying inside is strictly prohibited.

The effect of sulfur smoke persists not only on the day of fumigation, but also for the next 2-3 days. Then the greenhouse needs to be ventilated.

Spring

At the beginning of the season, use a sulfur checker at least 2 weeks before planting seedlings. Therefore, the start time of work is calculated according to which crop will be grown.

But the following conditions must also be taken into account: the air temperature must not be lower than 10 ºС, the soil must dry to a depth of 10 cm. The soil must not be wet so that sulfurous acid cannot enter the soil, where it will negatively affect soil bacteria .

Autumn

Autumn treatment with a sulfur checker of a polycarbonate greenhouse is carried out after the harvest is harvested and all plant residues are removed. As in spring, you need to focus on the air temperature in order to have time to process before the onset of cold snap and frost.

You need to fumigate the greenhouse until the tablets are completely burned, this may take 1-1.5 hours. The calculation of the number of tablets is carried out depending on the volume of the greenhouse and is 50-150 mg per cubic meter. m.

Safety rules

When handling a smoke bomb, precautions must be strictly observed - the smoke is poisonous to animals and humans. It is necessary, first of all, to take care of the protection of the respiratory organs and eyes, wear a respirator and goggles. If you inhale smoke, you need to urgently go to fresh air.

Store sulfur checkers in their original packaging, hermetically sealed. Moisture should not penetrate to them so that they do not become damp. Storage temperature - room temperature. The shelf life of the disinfectant is 5 years.

Do I need to wash the greenhouse after the sulfur bomb

This is not necessary, it is recommended, on the contrary, to leave everything as it is for the best effect. 2 days after airing, you need to inspect the walls of the greenhouse, if there was mold on them, it should soften. In this state, it is easy to clean off surfaces.

To restore the soil after exposure to sulfuric smoke, add biological preparations containing beneficial bacteria or organic matter in which they are also present.

Fumigation with a sulfur bomb of a polycarbonate greenhouse is used in spring or autumn as a means of disinfection. It is especially effective when it is necessary to destroy pests or pathogens of bacterial infections, mold, fungi, which often affect greenhouse plants and can be resistant to folk and chemical agents.

Sulfur balls are used after growing the same crop in a polycarbonate greenhouse for several consecutive seasons, when the likelihood of pathogen reproduction increases. With timely treatment of the premises from pests and pathogens, the chances of secondary infection are significantly reduced. This helps protect future crops from dying or partially reducing yields.
