The drug Hom (copper chloride): use in gardening

The fight against garden diseases is one of the components of growing vegetable crops. Fungus is the most common. Therefore, fungicides come to the rescue - special preparations that can remove fungal spores in a short period of time. Finding a potent substance is always difficult.

The problem is that not all of them preserve the harvest or have a beneficial effect on the soil. Hom or copper oxychloride is popular.

It is characterized by productivity during treatment for fungus, good time indicators, and positive characteristics in preserving the harvest. Use is allowed both in the vegetable garden and flower beds. Which is also a positive thing.

Description and characteristic properties of the drug

The drug Khom is known to gardeners, flower growers and gardeners as not only a therapeutic, but also a preventive remedy. Widely used for all crops:

• vegetable;
• fruit;
• for ornamental crops.

If diseases and pests encroach on a plot of land, then the fight will be easier with Khom.

Helps remove:

• moss on fruit trees;
• late blight on tomatoes, potatoes;
• peronosporosis on onions, cucumbers;
• leaf curl, which is more common on peaches;
• scab on apple and pear trees;
• rot and mildew in vineyards;
• spotting and rust.

The product called “Hom” is universal and easy to use. It is considered a substitute for Bordeaux mixture. The appearance also resembles the above mixture:

No additional additions are required when diluting the powder with water. Hom is immediately ready for use. The only negative is that it is quickly washed off when watering from a watering can during the rainy season.

Need to know! Experts recommend using a simple method for long-term effects and preservation of diluted “Homa”: add milk. Proportions to add: 1% of the total volume.

Pros and cons of use

Copper oxychloride is an analogue of Bordeaux mixture. There is a small drawback to using this drug: the product is poorly retained on plants. The copper oxychloride solution is also quickly washed off by rain.

In conditions of highly moistened crops that are particularly sensitive to preparations that contain copper, the preparations very often cause netting on the fruits and burns of the leaf blades.

When copper gets into the soil, it does not decompose, but accumulates.

The advantage of its use is the ease of preparing the solution. That is, all that needs to be done to prepare it is to mix copper oxychloride with water, in which it dissolves very quickly.

Another advantage is that the drug has no side effects on plants.

Copper oxychloride is a universal product that is used to treat fruit trees, vegetables, berries, shrubs and flowering plants.

The drug can additionally be used to repel the Colorado potato beetle.

If the norm recommended for use is observed, the drug almost completely decomposes in the soil with the formation of chlorine and copper ions within 1 to 6 months.

Copper oxychloride is an inexpensive fungicide of moderate toxicity. The shelf life in undamaged packaging is unlimited.

The drug also combines well with most pesticides, and when used wisely it shows very high efficiency.

To increase the retention (“stickiness”) of a copper oxychloride solution on plants, shrubs, and vegetable crops, experienced gardeners recommend adding a small amount of one percent skim milk to the prepared solution.

Intended use of the product

The drug oxychome is a contact agent, which indicates the effect while it is on the surface. By covering the leaves with a thin layer, the trunk of the Hom plant prevents the penetration of a fungus or other disease or parasite inside.

But the effect lasts as long as the product is on the surface. During the first rainfall, the substance is washed off and no longer has the necessary protective effect.

Instructions for use indicate the possibility of use at all stages of plant development, except flowering. But there is also one more disadvantage: Hom helps only in the initial stages of infection.

Treatment will help in the presence of pathogenic microorganisms until sporulation occurs. If you skip this moment or start it, the desired result will not be obtained.

Hom can perfectly fight moss on apple trees. It will be useful in the garden if protection is needed for plums, apricots, peaches or cherries. Removes consequences and initial development:

• clusterosporiasis;
• coccomycosis;
• curliness and moniliosis.

But the use of copper oxychloride in gardening requires a larger amount of working solution: 1 tree will require at least 2 liters, but no more than 5 liters. Useful for quince and pear as well.

Recommended in vineyards, as the vine is a tasty morsel for scab, mushrooms and curls. Often affected by mildew and anthracnose. But Hom will help in this case too.

Composition, effects

For agronomic purposes it is produced as crystalline hydrate, in the form of a wettable powder (SP).

HOM is chemically resistant. This is explained by the low mobility of positively charged copper ions. Therefore, they do not actually penetrate plant tissues, which means they do not pose a danger to them. But when combined with biological microorganisms, the situation changes. Fungal pathogens activate copper mobility, resulting in their death. Such interaction is possible only with barely germinated spores; mature mature microorganisms are not subject to the control of HOM; it cannot cope with them.

Therefore, copper oxychloride is used as a prophylactic or in the initial stage of plant infection, since, in the later stages of disease development, the drug is completely useless. In other words, this fungicide is beneficial only before the fungi enter the sporulation stage. As a last resort, before their hyphae fill the infected plant. That is, it should be used when the first signs of the disease appear.

It is extremely difficult to diagnose at an early stage. If there is an error, the drug will not work. But, due to the fact that it is used at the beginning of the development of pathogens, there is time to replace it with another drug.

Arguments in favor of the use of copper oxychloride are its detrimental effect on many types of pathogens. In addition, the substance does not accumulate in plant tissues, therefore it is not dangerous for humans.

Advantages and disadvantages

Hom fungicide is a fast-acting, broad-spectrum fungicide. Rescues and protects from pests. Positive qualities include:

• the pricing policy allows all segments of the population to buy the drug;
• accessibility when using;
• compatible with most substances that are often used in the garden;
• Hom is processed not only as a therapeutic agent, but also as a preventative;
• The spectrum of action extends not only to fruit and berry crops, but also to ornamental plants.

Analogues of the drug

Currently, there are a huge number of drugs on sale based on copper oxychloride.

The most popular is "HOM". Its popularity is due not only to its high efficiency when used, but also to the fact that it is a ready-made product that does not require any additional additives.

Less popular, but no less effective: “Copper Oxychloride”, “Zoltozan”, “Vitigran”, “Devicooper”, “Kuprikol”, “Kupritoks”, “Blytox”, “Bakarni-krag”, “Mikropiy”, “Perecid 50” ", "Rekop", "Bladkupfer", "Rodiacuvir", "Varikuvir", "Kauritil", "Cobox", "Koskisan", "Kaloidox", "Copesan" and many others.

Recommendations for use

Khoma's working solution must be liquid. To do this, the powder will need to be well dissolved in water. As for watering, each plant has its own dosage and certain recommendations. Initially, a concentrate is made.

Then it is further diluted and applied to the crop. The standard application of fungicide is spraying. They try to cover not only the leaves, but also the trunk parts, as well as the ground around the root.

How to prepare a solution for treatment

Hom product is sold in dry form for ease of unpacking and use. The required amount is added to a small volume of water. This is how the working concentrate is obtained. Gradually adding liquid, the mixture continues to stir.

Application should be even. You should use a spray bottle. It is recommended to dilute it with milk for spraying. This method prevents the substance from quickly disappearing after application.

After preparing the solution, it is not recommended to store the working mixture. The entire area is treated without exception. Thus, for ornamental crops, it is undesirable to apply Hom during the flowering period.

The maximum protective effect lasts up to 30 days. Taking into account rains, up to 7-10 days.

Required dosage

Oxychom fungicide to protect vegetable crops or garden trees should be diluted at a certain dosage per 10 liters of water. The dilution procedure is carried out according to the standard procedure: first, the working solution. Then only complete receipt of the processing substance:

• grapes, hops – 40 g;
• onions, tomatoes, cucumbers – 40 g;
• beets, potatoes – up to 40 g;
• all flowers - no more than 30 g.

Treatment of the garden with Hom against all fungal diseases should be carried out by diluting 40 g of powder per 10 liters. water.

What is copper oxychloride and what is its principle of action?

Copper oxychloride is a contact fungicide that is moderately toxic. This substance is used to make various drugs that help cope with many diseases.

The activity of the element is aimed at suppressing the mineralization of organic compounds. The substance is considered easy to prepare and use. To prepare the solution for spraying, it is recommended to mix 90% of the powder with water. The disadvantage of the substance is the rapid evaporation from the surface of the foliage after precipitation. In addition, with frequent treatments there is a risk of large amounts of copper accumulating in the soil.

Copper oxychloride is part of many products that are used to prevent pathologies and treat plants. The substance helps with the following ailments:

• scab;
• powdery mildew;
• coccomycosis;
• anthracnose

This is not a complete list of problems that the substance helps solve. It successfully copes with fungal infections, various types of rot, and parasites.

Rules for applying fungicide

All vegetable and berry crops, as well as trees, are treated with Hom during the growing season. Ornamental crops are the opposite: either before or after flowering. During the appearance of buds, Hom is capable of causing harm. The working mixture is applied to the leaves and root parts carefully. Look for full coverage.

Application is prohibited at temperatures above 25 degrees. It is better to do this in the early hours or in the evening. The weather is calm. The working mixture is valid for only 24 hours.

But experts say that the best result will be achieved if the application is carried out 1-2 hours after dilution. Stir additionally before spraying.

For vegetable crops

For cucumbers, onions or turnips, Hom is useful for peronosporiasis, bacteriosis and anthracnose. The permissible number of treatments is a maximum of 3. For spotting, the number of treatments increases to 4 times. And against late blight for potatoes or tomatoes, it is better to do it 5 times. The solution is made into 10 liters.

For berry bushes

For wild strawberries, strawberries and grape bushes, up to 4 treatments can be carried out during the gardening season. For prevention or in the early stages of the disease, 150-250 ml of the working mixture is consumed per bush. The recommended dosage for grapes is 30 g.

For trees

Khom is used for trees as a prophylactic or medicinal drug. The dosage does not change. 40 g per 10 liters. Spraying over the entire trunk, branches and leaves.

Need to know! Green spaces are not treated if the crop has not been sick before and fungal infections have not been observed on the soil - Hom is not used. For healthy soil and plants, biological products are chosen for prevention.

Application in horticulture

Gardeners know that there are many preparations in which the main active ingredient is copper oxychloride . The drug Hom has become very popular; Zoltozan, Blytox and others are also selling well and are well-deserved by gardeners.

Copper oxychloride is a fungicide. It is usually sold in the form of a ninety percent emerald crystalline powder with a blue note. Packaging is done in polyethylene bags. The net weight of each package of the product is two hundred grams.

The drug is used to combat the following diseases of horticultural crops:

1. Fruit tree scab
2. Coccomycosis and the like
3. Anthracnose
4. Pest extermination
5. Rot and fungi
6. Powdery mildew

It should be borne in mind that the effect of the drug lasts approximately two weeks, and in case of precipitation, the treatment must be repeated immediately.

No negative reactions of plants to the use of copper have been identified, however, you should be aware that young leaves may get a little burned.

The preparation method is extremely simple - the powder is diluted with water and quickly dissolves, then the solution is brought to the required volume with water.

Shelf life and requirements

Toxicity class – 3. This indicates low toxicity. In this case, it is better to use protective equipment: respirators, goggles. The ban on spraying during the flowering period arose due to the negligible threat to bees and their products after nectar collection.

Reviews say that Hom does not cause side effects, i.e. it is environmentally friendly. Accumulation occurs for up to 3 weeks, after which it evaporates without residue from the soil and plant. Gets along well with other fungicides.

But it should be used wisely, with a time gap. The shelf life in sealed, dry packaging is unlimited. The liquid cannot be stored. Use immediately after dilution.

Precautions for use

When contacting copper oxychloride, you must use protective equipment: gloves, mask, goggles.

If the drug accidentally gets on the skin or in the eye, it must be washed off immediately with plenty of clean running water.

If ingested, the drug can cause inflammation of the gastrointestinal tract.

Copper oxychloride is non-toxic for bees, but it is better to isolate insects before treatment, and after treatment they must be left for an additional 6 hours.

HOM drug - instructions for use

When working with the drug XOM, the instructions for use must be followed. The drug is in the form of a water-soluble green powder, it is packaged in small packages of 20 and 40 g, as well as in large boxes of 10 and 20 kg. The first type of packaging is suitable for home use, the second is more profitable for industrial cultivation of crops.

It is not used in its pure form; for spraying, the drug must be prepared according to the following algorithm:

• measure the required amount of concentrated powder in a large container (it should not be metal);
• dilute with water in the proportions indicated in the table and stir;
• pour the working solution into a container with a spray bottle;
• distribute the liquid evenly over the above-ground parts of the plants;
• the drug is not stored in diluted form - it should be prepared for one use and used immediately.

HOM fertilizer, according to the instructions, is allowed for use throughout the entire growing season, except for the period of flowering and fruiting. The harvest becomes suitable for consumption only after 3-4 weeks, and cucumbers and tomatoes - after a week.

Pharmacological properties of the fungicide "Hom"

To understand the essence of the drug’s effect on fungal pathogens, you need to understand what copper oxychloride is and how it affects microorganisms. Penetrating into their cells, the substance interferes with the processes of mineralization of organic substances, disrupting and neutralizing them. Thus, the cells gradually die, and along with them the causative agent of the disease itself. It is noteworthy that the drug is not addictive to microorganisms and has a 100% effect on them in every case.
