Rules for processing greenhouses in spring with copper sulfate before planting seedlings
Greenhouses protect plants from adverse weather conditions, but harmful microorganisms, insects and fungi can easily get inside. Processing the greenhouse with copper sulfate in spring or autumn can effectively disinfect the soil and the entire structure.
Processing is carried out after the end of the summer cottage season or in early spring, when at least a couple of weeks remain before sowing or planting. There are many products available for home disinfection. But copper sulfate is universal. A summer resident can spend the spring copper sulfate treatment land in the greenhouse. The same remedy will help where water is powerless, that is, it will clean the inside and outside of greenhouse structures of all types.
It is especially important to keep the greenhouse clean and regularly treat the greenhouse with copper sulfate in the spring if the plants showed signs of bacterial or fungal diseases last season.
Copper sulfate is a highly active inorganic fungicide that has the properties of an antiseptic that works on all surfaces, as well as a microelement additive that replenishes the lack of copper in the soil. All the beneficial properties of the chemical are found in horticulture and horticulture.
Safety measures when processing greenhouses with copper sulfate in spring
Copper sulfate is moderately toxic. In acceptable dosages, the product will not harm the skin, but it can burn the mucous membranes. The blue powder or solution is washed off with plenty of water. However, when a chemical enters the digestive tract, more effective measures are taken:
- the esophagus and stomach are washed with a pink solution of potassium permanganate;
- cause gagging;
- give diuretics and laxatives.
Following the instructions will help to avoid the unpleasant consequences of contact with copper sulfate. In autumn and spring, the treatment of the greenhouse with copper sulfate is carried out with gloves and a mask, using non-food non-metallic dishes.
Before treating the greenhouse with copper sulfate in the spring, make sure that children, unprotected family members and pets are not allowed to be near the irrigated area.
How to dilute copper sulfate for greenhouse processing
To clean the greenhouse, a solution is prepared on the basis of copper sulfate, with which the soil, frame and coating are successively treated. At the same time, the concentration of the chemical for soil disinfection should be much lower. This is due to the increased acidity of copper sulfate, its negative effect on the fertility of the substrate and the ability to accumulate.
Before diluting the copper sulfate for processing the greenhouse, all plant residues are carefully removed inside, the working tools, irrigation containers and reusable containers for seedlings are taken out and disinfected separately. Then comes the soil's turn. In this case, the content of copper sulfate should be no more than 50 grams per bucket of water, and the consumption should be about 2 liters per square meter.
In spring, soil cultivation in the greenhouse with copper sulfate in combination with lime, which neutralizes the increased acidity of the solution, reduces the toxicity of the chemical. At the same time, the summer resident will be able not to lose the fungicidal effect of the liquid on pathogenic fungi and other pathogens of plant diseases.
You can get the desired composition by separately mixing solutions of copper sulfate and lime, and then, gently stirring, pouring the blue liquid into the milk of lime. After stirring and straining, the product can be applied.
How to treat a greenhouse with copper sulfate in spring? To wash the film, polycarbonate, metal or plastic frame, a solution is used, which is prepared at the rate of 100 grams of vitriol per 10 liters of water.
- While stirring, the powder is dissolved in a small volume of warm water.
- Then the concentration is adjusted to the desired concentration by adding the required amount of water.
- To improve the adhesion of the solution to the material and enhance the detergent properties, 150 grams of liquid or crushed laundry soap is added to the water.
How to process a greenhouse with copper sulfate in spring
After cleaning and burning plant residues, all structures are washed with soap or other household product:
- It is useful to prime and paint the metal frame. This will extend the life of the greenhouse and prevent corrosion.
- The wooden frame is pre-impregnated with a saturated solution, at the rate of 700 grams per 10 liters of water, with a solution of copper sulfate, whitewashed with slaked lime or covered with a layer of paint for trees.
When the sanitization is completed, it is time to move on to mixing the copper sulfate solution and irrigating the inner space of the garden structure with it. Especially carefully the lower coating elements in contact with the ground are treated. After complete drying, the treatment is repeated.
How to cultivate the land in the greenhouse with copper sulfate? In its pure form, the chemical accumulates and can degrade the quality of the soil. Therefore, it is advisable to use a solution of copper sulfate in the fall and once.
It is much safer to use bordeaux or burgundy liquid. The solution is poured over the entire area of the greenhouse, including the paths. It is better to carry out the treatment after watering, then the solution is more easily absorbed. The action of copper sulfate begins 1-3 hours after mixing and ends after 10-14 days. To achieve the maximum efficiency of the greenhouse processing with copper sulfate, dry, windless, but not hot weather is chosen in spring.
