The traditional treatment of trees with copper sulfate in spring is used as a preventive measure and is aimed at protecting crops from the most common pathogens and plant parasites. When working with copper sulfate, it is very important to observe safety precautions and be sure to use a respirator such as "Petal".
Terms and conditions for spraying the garden
It is recommended to treat fruit trees and berry bushes with well-known iron or copper sulfate in our country in early spring. In the first decade of spring, before the stage of active budding of the buds, spraying from diseases with vitriol is required. Before flowering, it is necessary to treat the plants from pests such as gall midges, sawflies, ticks and aphids. To this end, you can apply "Karbofos " or Actellik. Before budding, the fruit stands can be sprayed with a solution Nitrafen at the rate of 0.3 kg of the drug per 10 liters of water.
Spring spraying of trees and shrubs is carried out immediately after flowering, and then after a couple of weeks. Processing is carried out on a cloudy and warm day, at a temperature of 18-20 ° C, in the early morning. Proper prevention of diseases and pests of garden plantings involves a set of measures. Of the most commonly used preparations containing copper sulfate, one can name such affordable, but effective, as Bordeaux mixture and "HOM".
|Garden culture||Damaging factor||The concentration of the drug before budding||The concentration of the drug during the growing season|
|Vine||Mildew infection||3% solution||1% solution|
|Apple trees||Infection with scab, moniliosis and bacterial cancer||3% solution||1% solution|
|Peaches||Infection with curly leaves and bacterial cancer||3% solution||Not used|
|Apricot||Spotting, moniliosis||3% solution||1% solution|
|Cherry||Infection with hole spotting, moniliosis, bacterial cancer||3% solution||1% solution|
|Sweet cherry||Infection with kleasterosporiosis, bacterial cancer, moniliosis||3% solution||1% solution|
|Pear and quince||Infection with scab, phylosticosis, spotting, moniliosis and drying||Early spring spraying at the rate of 2-5 liters per tree at a concentration of 100 g per 10 liters of water||Not used|
|Gooseberries and currants||Infection with anthracnose, septoria and spotting||50-100 g per 10 liters of water||Not used|
Spraying the garden plantings with urea or urea not only helps protect fruit trees from pests, but also delays the flowering of plants, which helps to avoid yield losses due to the negative effects of spring return frosts.
Types of spring spraying
Terms and rules for spraying the garden
Preventive treatment with copper sulfate is widespread in the disinfection of soil in a greenhouse or greenhouse. For spraying garden plants, a 2% solution of the agent is used. Plants with severe disease damage should be treated with this drug at a concentration of 5%.
In the spring, it is necessary to spray plants with a solution of malathion at the rate of 30 g per 10 l of water. This tool has proven itself in the protection of garden strawberries from ticks, as well as other plantings from aphids and tinnitus. Garden soil under berry bushes should be pollinated with 12% dust of hexachloran at the rate of 50 g per bush before the beginning of active leaf blooming. Pollination of the soil allows you to save the garden from damage by such common pests in our country as gall midges, ognevka and gooseberry sawfly.
The prepared 1% solution is used for the following purposes:
- prevention of late blight, alternariosis and black bacterial spotting on tomatoes;
- prevention of late blight on potatoes;
- prevention of peronosporosis, rust and rot onion crops;
- prevention of anthracnose, peronosporosis, olive spotting and bacteriosis on cucumbers.
The use of copper sulphate as a fertilizer also works well.. Copper sulfate is introduced once every five years. This type of feeding is carried out in the early spring or in the fall with the consumption of one gram per square meter. Before use, the drug should be thoroughly crushed and mixed with soil. For foliar feeding of vegetative plants, the standard concentration of the solution is 1-2 g of copper sulfate per bucket of water. To destroy black cabbage, tomato rot, Fusarium or yellowness on cabbage crops, as well as diseases that affect radishes, turnips and swede, watering is carried out at a rate of 5 g of copper sulfate per bucket of water.
Terms and rules for spraying soil in a greenhouse
Experienced vegetable growers recommend spraying greenhouse soil with well-established chemical products, which allows the planting of popular vegetable plants such as tomatoes, peppers, eggplant and cucumbers in the land clean from pathogenic microflora. Proper and timely use of chemicals reduces the risk of accumulation of harmful substances in the resulting vegetable and green products. Currently, several methods of processing greenhouse soil are practiced, including biological, thermal, in the form of heating and steaming, as well as chemical.
Most often, Bordeaux liquid, which consists of a mixture of lime and copper sulphate, is used to disinfect the soil in closed ground conditions. A pair of enameled containers should be filled with hot water and dissolved in it copper sulfate and hydrated lime in an amount of 0.3 kg. The lime solution should be filtered and combined with a solution of copper sulfate. The correctness of the preparation of the composition can be checked using a litmus test: it turns blue. Ready-made mixtures based on copper and iron sulfate are also popular in home gardening and horticulture.
It is necessary to begin spring processing of the garden before the snow completely melts. In February, a thorough inspection of fruit plantations and berry bushes should be carried out. During this period, it is required to inspect the cultures for the presence of nests of wintering plant parasites. All pests found should be destroyed. Damaged shoots must be removed and burned. The next step in early spring processing is the whitewashing of the stem and the main skeletal branches.
Additional activities should also include the following spring work:
- cleaning fallen leaves and plant debris, where a significant amount of pathogenic microflora and wintering plant parasites;
- loosening of soil in near-stem circles and removal of all weed vegetation;
- conducting mulching of the soil in near-stem circles using organic matter;
- the introduction of nitrogen-containing fertilizers in the form of slurry, bird droppings and mullein.
In the spring, it is necessary to install trellises and props necessary for the full growth and development of climbing plants. In the same period, decorative conifers planted, as well as basic fertilizers. When planting and immediately after flowering, mineral fertilizers or organics should be applied. Nitrogen-containing fertilizers are applied at the rate of 45-50 g of ammonium sulphate and 20-25 g of ammonium nitrate per square meter. Sowing green plants gives a good result, which can be mowed twice during the growing season and plowed into the ground.
Spraying trees: blue vitriol
In the first decade of spring, you can engage in the division of flowering perennials, which allows rejuvenation of plants with minimal cost. It is very important to carry out protective measures when there is a threat of late spring frosts. You can use smoke or sprinkling, as well as use almost any covering material. Compliance with agricultural technology and the timely conduct of the main spring events allows you to get not only healthy, but also abundantly bearing garden and horticultural crops.
