Before beginning treatment, the greenhouse must be completely tidied up. Even after harvesting, plants leave seeds and roots in the soil, which may harbor pests or their eggs. Therefore, it will be necessary to thoroughly remove all plant debris and remove at least seven centimeters of old soil.

It's essential to dig over the soil in the greenhouse for the winter. This will cause many larvae to rise to the surface and die from the cold during the winter. For example, this is an extremely important measure for controlling mole cricket larvae. As for cockchafer larvae, they reside in the dense soil layer, so you'll have to till the soil by hand to get rid of them. Additionally, it's recommended to treat everything with a solution, and do so before the first frost.

Advice! When carrying out preparatory work before starting to treat the greenhouse in the fall from pests and diseases, to improve fertility next year, remove dried dirt from the walls.

Proper soil disinfection

To combat late blight and pests, greenhouse soil must be properly treated in the fall. This means not only using a special solution, but also adding other ingredients depending on the specific disease or pest you want to prevent. For example, to get rid of spider mites, sulfur burning is essential.

If using sulfur, prepare special wooden or metal structures. Fill them with sulfur, ensuring there is up to 100 grams of the substance per square meter. You can also use ready-made sulfur candles, each containing 60 grams of the substance. In this case, the treatment must be carried out very carefully, and a gas mask must be worn. To increase the toxicity of the sulfur, pre-wet the greenhouse with water. After treatment, ventilate the greenhouse and rinse it thoroughly.

Sulfur checkers are excellent for antibacterial treatment of greenhouses and their interiors. When burned, they produce smoke that penetrates all microcracks and crevices, even the topsoil. methods of autumn processing of currants.

Rules for processing with a sulfur checker:

1. Before starting treatment, tightly close all cracks, windows and doors to prevent smoke from escaping from the room.
2. Place a sulfur candle in the center of the greenhouse. If multiple candles are used, arrange them symmetrically throughout the space.
3. Light the wick and leave the greenhouse, closing it tightly so that the smoke does not escape.
4. Leave the greenhouse closed for a day, then ventilate it well and wash the walls with water.

Events after

After using sulfur checkers, there will be acid on the greenhouse walls, which must be removed. As mentioned before, the walls need to be washed. Regular water can be used, but a 1-2% pemoxol solution works best. After treating the walls, remove any remaining solution using nylon brushes. Finally, rinse with regular water.

About soil preparation

Any video on how to treat a greenhouse for pests and diseases in the fall will tell you to dig up the soil. Don't forget to fertilize the soil during the fall preparation period. Be sure to add some peat moss, humus, and manure at a rate of half a bucket of fertilizer per square meter.

After fertilizing, sprinkle sand or ash around the greenhouse at a rate of one liter per square meter. Finally, cover the soil with resin. In winter, you can also add snow to the greenhouse: it will protect the soil from freezing in winter and provide sufficient moisture in the spring.

Determining processing times

Pest and disease treatments for the following year are mandatory in the fall. Spring treatments for this purpose are also available, but they are not as effective. Much will depend on the soil temperature: the lower the temperature, the faster the gas released during treatment is absorbed.

Again, it's important to remember that sulfur should be used sparingly for treatment. It produces an acid that can negatively impact the quality of the future harvest. Treatment can be carried out any day in the fall, but it's important to do it before the onset of frost. Important stages of autumn garden pest control.

Other possible methods of autumn treatment:

1. For plastic greenhouses, it is recommended to remove the material from the frame and dry it thoroughly. The structure is treated with bleach (400 ml of bleach per bucket of water, let it sit for four hours). The resulting solution can be used to spray the soil.
2. A wooden greenhouse is treated with copper sulfate. Treating a wooden greenhouse in the fall against pests and diseases with copper sulfate helps keep the structure in good condition until spring. Scald the containers used for growing crops with boiling water.
3. A steel greenhouse does not require any serious treatment; it can simply be coated with lime or simply painted.

To ensure a good harvest in your greenhouse next year, it's essential to prepare it for winter and the arrival of spring in advance. This is because in late autumn, just before the first frost, pests have already gone into hibernation and laid their eggs. This presents a unique opportunity for gardeners to eliminate pests when they are completely defenseless.
