Copper oxychloride: application in gardening


Copper oxychloride (or "Hom", copper oxychloride, blitox, cupricole, zoltosan, cupritotox) refers to fungicides of moderate toxicity. It allows you to quite effectively deal with various plant diseases: with brown spot, macrosporosis, late blight, scab, curly, powdery mildew, rust.

Chloroxide copper (the average price is 16-18 rubles. Per pack of 40 grams) does not have side effects on the treated plants. Contact requires protective measures (gloves, mask, goggles). A preparation that accidentally gets on the skin or eyes should be immediately washed away with plenty of running clean water. For bees, the fungicide is low toxic, however, it is better to isolate the hives before treatment (with an exposure time of at least 6 hours after treatment).

The drug copper oxychloride is an analogue of the Bordeaux mixture (substitute). A small minus, associated with a weaker retention on the plant, is neutralized by a significant advantage, hidden in the simplicity of preparing the working solution (the drug is simply mixed with water and dissolves quickly in it).

Plants are recommended to spray only during the growing season.

Methods of use for protection against diseases

1. To protect against moniliosis and scab, six sprays of the tree are required, the first spraying should be when the buds appear pink (pink), the second - immediately after flowering, then - with an interval of 15 days (if necessary). Consumption rate - 35 gr. on a bucket of water (on average).

2. Against the curly leaves of apricot, cherry, peach, plum and cherry, against coccomycosis and klyasterosporioz four spraying will be required: first - with buds that are still swollen, but not bloomed, the second - immediately after flowering, two more with a two-week interval. Consumption rate - 35 gr. on a bucket of water (on average).

3. To protect potatoes from macrosporosis and from late blight, five treatments are required: when budding, the first treatment (for insurance), if there are signs of one of the aforementioned diseases, the next treatment, three subsequent ones, if necessary, with a two-week interval. Consumption - 40 gr. on a bucket of water. On the treated areas, the larvae of the Colorado beetles are also dying, and mature insects of the treated landings are avoided.

4. To protect the crops (planting) of onions or cucumbers from peronosporoza, treatment is carried out only when signs of one of these diseases are detected. Re-treatment - after two weeks. Consumption - 40 gr. on a bucket of water.

5. With peronospora hop, the treatment is carried out when a disease is detected, then every 16 days, further, if the weather is dry, and every 10 days, if it rains.
The last treatment can be carried out three weeks before the harvest, regardless of the type of crop.

To increase the retention (stickiness) of the solution, it is recommended to add a small amount of 1% skim milk.

Copper oxychloride is largely non-phytocidal for most of the cultures, however, tender, especially sensitive plants can later be burned.

The drug is well combined with many pesticides and with reasonable use shows very high efficacy. The shelf life of copper oxychloride packed in paper bags is practically unlimited.

Application in gardening

Gardeners know that there are many drugs in which the main active component - it is copper oxychloride. The drug Hom became very popular, it also sells well and enjoys the deserved respect of gardeners Zoltozan, Blitoks and others.

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

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

  1. Scab of fruit trees
  2. Coccomycosis and the like
  3. Anthracnose
  4. Pest Control
  5. Rot and fungi
  6. Mealy dew

It should be borne in mind that the effect of the drug lasts about 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 burned a little.

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

Work with the drug

Copper chlorine refers to substances with moderate toxicity, but, despite this fact, of course, you should observe the precautions when working with the substance. Be sure to wear a protective mask and gloves. Clothes, like shoes, should be closed, you should wear a hat, scarf, hat or other headgear on your head.

In case of contact with skin, especially mucous membranes, allergic reactions, irritation, itching are possible. Therefore, it is necessary to immediately wash the skin on which the drug fell, a large amount of running water. In severe cases, you should consult a doctor. In any case, after working with the drug, you need to thoroughly wash your face and hands with laundry soap.

If an accidental ingestion of an agent has occurred, it is necessary to try to induce vomiting, then take activated charcoal or another sorbent, at the slightest deterioration of the condition, immediately contact the clinic. When working with the solution is not recommended to eat, drink, smoke.

Naturally, all drugs must be stored. out of the reach of animals and children, preferably in a closed container, away from food. Storage should be dry, without direct exposure to ultraviolet rays, storage temperature from minus ten to plus twenty-five degrees, the shelf life of the drug is not limited.

Tip: the solution may harm the health of the bees, so during flowering processing is not performed, and a few hours before spraying crops isolate hives. After spraying, the hives can be placed on the site after about five hours.

Well proven the use of the drug in the vegetable garden. Potatoes can be processed no more than five times per season, this will protect the potato from late blight. By the way, the drug deters the Colorado potato beetle and kills its larvae. Prepare the tool must be in such a way that a hundred meters of the field used no more than ten liters of the finished product.

  1. Processing of cucumbers is carried out three times, during the growing season. Spraying protects against diseases such as bacteriosis and peronosporoz. The money spent in the same amount as in the case of potatoes.
  2. Tomatoes are processed up to four times per season, which will protect the brown spot, macrosporosis and the like from spotting. The expense will make one liter of ready means on ten square meters of landings.
  3. Beets are sprayed no more than three times per season, which will allow to avoid chalcosporosis. The amount of consumption does not differ from the consumption when processing the remaining vegetables.

Tip: Any vegetable crops are processed during the growing season. Spraying is carried out every ten days, taking into account the total number of maximum treatments. It is important that the last treatment can not be later than twenty days before full maturity.

In the garden, all of these drugs, based on copper oxychloride, are also applicable. They are good at processing cherries, plums, peach and other trees. Spraying will effectively protect the trees from curl, coccomycosis, moniliosis and other diseases. Each tree will need up to four liters of the finished (diluted) drug. Apple and quince drug protects against scab.

Vines of grapes can hit anthracnose. To protect the plants from this scourge, it is necessary to process the vines during the growing season. Spraying of vineyards is carried out no more than six times per season. Consumption will be about two liters of diluted, according to the instructions, the drug for ten meters of the vineyard.

Flowers are sprayed no more than twice a season, the first - before flowering, the second - after. Hom will help to cope with rust and spotting on the leaves of flowers. Consumption - about one liter per ten square meters of flower beds.


Copper Oxide Preparations quite inexpensive and affordable for almost everyone gardener or gardener. They were used in Soviet times, and have not lost their relevance to this day. Ease of use and effectiveness will allow the use of the drug and professionals, and novices, and large farms, and small auxiliary areas. That is why it is possible to recommend the purchase and use of copper oxychloride to every gardener and gardener.

Chloride of copper: purpose, principle of action, application

Copper oxychloride is a fungicide of protective and contact action of moderate toxicity.

Preparations based on it are effective means of preventing and treating many plant diseases: brown spot, macrosporosis, late blight, scab, curly, rust, powdery mildew.

The best result from the use of the drug can be observed when plants are sprayed with them for prophylactic purposes, that is, before the first signs of the disease appear.

Instructions for use in gardening

Immediately it should be noted that in one season this preparation can be carried out from two to six sprays with an interval of 10-14 days. The treatment solution is made at the rate of 40 grams per 10 liters of water.

The finished solution of copper oxychloride can be used for spraying fruit trees (apricot, cherry, peach, plum, apple, pear) and vineyards.

When spraying flower ornamental crops, the solution can be made to have a weaker consistency. For its preparation, you can reduce the amount of copper oxychloride to 30 grams, and the amount of water left unchanged - 10 liters.

The use of a solution of copper oxychloride in the garden and in the vineyards

To prevent such fruit tree diseases as: coccomycosis, cluster sporosis, curly, moniliosis, scab, during the growing season they must be sprayed with a solution of copper oxychloride.

Up to 2 liters of solution should go to each young tree, up to 10 liters to a fruiting adult tree. You can process up to four times, and with a disease like scab, the number of treatments can be increased to 6.

To combat grape diseases such as: anthracnose and mildew, during the growing season, the plant is treated with a solution using one and a half liters per 10 m 2. For grapes, the number of treatments can be increased up to 6 times.

Flower culture is recommended to be processed only twice: before flowering and after it. Spotting and rust can be removed by spraying them at the rate of one and a half liters per 10 m 2.

Processing with copper oxychloride solution of vegetable crops

Copper oxychloride solution can also be used in the processing of vegetable crops:

  1. Potato processing. Potatoes in one season can be processed with this solution up to 5 times. This will help protect the crop from late blight and macrosporosis. For every 100 m 2 it is required to use up to 10 liters of the finished product.
  2. Processing cucumbers. Spraying cucumbers can be carried out three times and only during the growing season. Consumption is similar to the amount recommended for potatoes (per 100 m 2 - up to 10 liters). This will help protect the culture from anthracnose, perinospora, and bacteriosis.
  3. Tomato processing. Copper oxychloride solution helps protect tomatoes from macrosporosis, late blight, and brown spot. This vegetable crop can be sprayed no more than 4 times, spending no more than 1 liter of solution for every 10 m 2.
  4. Beet processing. The tool also effectively fights with beet germosis. To achieve a positive effect, the vegetable should be processed three times. The consumption of the solution is similar to the volume that needs to be spent on processing cucumbers and potatoes.
  5. Processing onions. To prevent such diseases as peronosporosis, onions must be processed three times in one season. The volume of the required solution: 1 liter for every 10 m 2.
  6. Hop processing. In case of re-incidence of hops, treatment is started immediately after the first signs of the disease are detected. The interval between treatments, if the weather is sunny and dry, is 16 days, and if it is cloudy and rainy, 10 days.

It should also be noted that the last spraying of any crop should be carried out no later than 20 days before the time of the planned harvest.

Pros and cons of use

Chloride copper is an analogue of the Bordeaux mixture. In the application of this drug there is a small minus: the tool is weakly retained on plants. Copper oxychloride solution is also quickly washed off by rain.

In conditions of strong moisture of crops that are particularly sensitive to drugs that contain copper, the agents very often cause a grid on the fruit and burns the leaf plates.

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

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

The advantages also include the fact that the drug has no side effects on plants.

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

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

At observance of the norm recommended for use, the drug almost completely decomposes in the soil with the formation of chlorine and copper ions within 1 - 6 months.

Copper oxychloride is an inexpensive, moderately toxic fungicide. Shelf life in undamaged packaging is not limited.

The drug is also perfectly combined with most pesticides, and with reasonable use shows a very high efficiency.

To increase the retention (“stickiness”) of copper oxychloride solution on plants, shrubs, and vegetables, experienced gardeners recommend adding a small amount of 1% skim milk to the finished solution.

Precautions for use

In contact with copper oxychloride it is necessary to use protective equipment: gloves, mask, goggles.

In the event that the drug accidentally gets on the skin or in the eye, it is required to immediately wash it off with plenty of clean running water.

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

For bees, copper oxychloride is non-toxic, but it is better to isolate insects before processing, and after processing it is necessary to additionally endure at least 6 hours.

Analogs of the drug

Currently on sale there are a huge number of drugs created on the basis of 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 tool that does not require any additional additives.

Less popular, but no less effective: Copper Oxychloride, Zoltozan, Vitigran, Devikooper, Kuprikol, Kupritoks, Blitoks, Bakarni-Craig, Micropy, Peretsid 50 ”,“ Recop ”,“ Bloodcupfer ”,“ Rodiakuvir ”,“ Varikuvir ”,“ Kaurilit ”,“ Koboks ”,“ Koskizan ”,“ Kaloidoks ”,“ Kopezan ”and many others.

Variety of remedies

Copper chlorosulfide is a chemical agent designed to kill plant pathogens. Regardless of the name of the drug, the best result from its use is observed when plants are sprayed with them for the purpose of prevention, even before signs of onset of the disease appear.

On sale you can find several trade names of drugs, the main active ingredient in which is copper oxychloride. One of the most famous is HOM, but also Kuprikol, Copper Oxychloride, Zoltozan, Kupritoks, Blitotox are popular on sale.

Use of the tool in the garden and in the vineyards

Choosing a drug to protect your plants, you need to know what pests can effectively deal with copper oxychloride. The instruction to the above preparations allows you to find out that it destroys the pathogens that cause such diseases of fruit trees as coccomycosis, cluster sporosis, curly, moniliosis, scab. To prevent these diseases it is necessary to spray trees during the growing season. Each should take from 2 to 5 liters of solution. You can process them up to 4 times, with scab the maximum number of sprays increases up to 6 times.

Grapes can affect diseases such as anthracnose and mildew. To combat them during the growing season, plants are treated with products containing copper oxychloride. Применение препаратов рекомендуется и для обработки декоративных культур. При этом учтите, виноградники можно опрыскивать до 6 раз, используя 1,5 л разведенного средства на 10 м 2 . А вот цветочные культуры можно обрабатывать лишь дважды: до и после цветения. Препараты позволяют убрать пятнистость и ржавчину, если опрыскивать их из расчета 1,5 л на 10 м 2 .

Обработка овощных культур

Experts recommend using these drugs not only in the garden, but also in the garden. Up to 5 times per season it is permitted to process potatoes using copper oxychloride. It protects these plants from macrosporosis and late blight. The solution is prepared in such a way that 10 liters are used to treat every 100 m2 of planting.

It is possible to plan cucumber spraying only during the growing season, it can be done three times. Consumption means will be the same as in the processing of potatoes. Chloroxide copper can protect them from bacteriosis, anthracnose, peronosporaz.

Tomatoes can be sprayed no more than 4 times, for every 10 m 2 of planting should be spent 1 liter of solution. Protect these plants from macrosporosis, late blight, brown spot.

Preparations also help to prevent the development of beet chickens. For these purposes, the plants are processed three times. The consumption of the prepared means should be the same as in the processing of other vegetable crops.

Preparation of the solution and basic recommendations

To protect the trees from clastrereporosis, moniliosis, coccomycosis, curl, 40 g of copper oxychloride is diluted in 10 liters of water. They are processed during the growing season. Apricots, cherries, plums, peaches are susceptible to these diseases. For processing vineyards, the solution is made in the same concentration. But for spraying flower ornamental crops, 30 g of the preparation can be diluted in 10 liters of water.

For processing vegetable crops, the solution is prepared in a standard way. Every 10 liters of water must be diluted with 40 g of product.

All plants can be sprayed only during the growing season. For maximum protection, the procedure should be repeated every 10 days - 2 weeks. At the same time remember that the last spraying should be carried out no later than 20 days before the time of the planned harvest.

Indications for use

In the general title of the article “prophylactically” it is not for nothing that is put in the first place. XOM fungicide is the next link in the fight against fungal diseases of plant crops after safe prophylactic agents such as Gliokladina and Trichotsin. HOM, in contrast to them, does not require time for the development of a pathogenic antagonist fungus: “chemistry” begins to act instantly. Also, HOM does not suppress, but kills harmful fungi and acts more strongly - with copper chloroxide, the disease that has begun can be cured. In contrast to more effective copper-containing agents (Bordeaux mixture), XOM, if properly used (see below), is almost as safe as biologics.

The treatment of HOM makes it possible to cure plants from a number of fungal diseases (see below), which cause leaf spotting, stem rot, scab and fruit rot, i.e. HOM is effective for plants at all phases of their development. But, if the disease is started up to the stages shown in Fig., Copper in the form of oxychloride will not help: you will have to resort to stronger, but also more stringent and dangerous means.

Symptoms of fungal diseases of plants cured by copper preparations

We emphasize: the use of HOM for plants is effective only in the initial stages of the disease, when pathogenic fungi have not yet entered the time of sporulation, or, in extreme cases, when their sporangia have not yet been emptied and the hyphae have not filled the affected specimen. In practice, this means that you must start an XOM immediately after the onset of the initial symptoms of the disease. Diagnostics of plant diseases may not be simpler than human ones, therefore we recommend readers - novice breeders to watch a video about clearly expressed and especially harmful fungal diseases of widespread garden and greenhouse crops:

More experienced owners of XOM may be useful as a substitute for stronger copper-containing drugs for treatment in early stages of plant diseases that are more difficult to diagnose “by drop”:

Note: the use of XOM facilitates its storage stability. Warranty period of storage of the drug in a carton box for 2 years, in evacuated sachets of 20 and 40 g is almost unlimited. If the HOM is poured out of the box immediately after purchase into an airtight container and taken out of it as needed in parts, then the drug will remain effective for 5 years or more. That is, the stock HOM is convenient to keep on hand, especially since it is inexpensive.

Order of use

The use of HOM for plant protection is carried out by spraying a tank solution. First, prepare, as usual, uterine, dissolving a dose of JV approx. in a liter of water. The mother liquor is poured into a 3/4 of the consumption rate (see below) filled in a sprayer tank, filled with water and sprayed.

An indispensable condition for successful treatment is that the day (preferably 2-3 days) after it does not rain: the easily soluble HOM is immediately washed off the plants. Therefore, the use of HOM is highly desirable only in the evening: the morning dew will wash it off too. The cultivated crops must first be watered properly so that after treatment they have enough soil for 2-3 days or more - irrigation water washes away HOM no worse than rainwater.

Schemes and doses

Chloroxide copper is not exclusively a fungicide. On plants with thin permeable covers, HOM can cope with some bacterial diseases. Instructions for the use of XOM for common types of garden crops are given in the table below. Explanations to it: first, in some cells of the “Use” column, the consumption rates for vegetables are given with a spread. In such cases, a large dose of treatment, it is given when there is evidence of disease.

Instructions for use of copper oxychloride for plants

Secondly, if last year the plants in the area did not suffer from these diseases, XOM, like the other “chemistry” from them for preventive purposes, is better not to use, limiting itself to prevention with biologics. But this indication is not valid if the neighbors or, for holiday villages, in the entire array, such diseases were.

The third - the general scheme of application is as follows:

  • Therapeutic treatments are carried out immediately when signs of the disease appear.
  • The first prophylactic treatment is carried out not earlier than a week after transplanting or full blooming of perennials.
  • Subsequent treatments are carried out not earlier than a week after the previous ones.
  • At the beginning of budding, the prophylactic use of XOM is stopped and resumed after the formation of ovaries.
  • Medical treatment during flowering is carried out in exceptional cases only in the evening. At the same time, the apiary protection zone is at least 2 km, the time of bee production is from 12 hours after processing, the summer time is up to 6 hours.
  • The last treatment is carried out no later than the time of action of the drug + week before harvest.
  • The multiplicity of treatments indicated in the table is not obligatory, it is the maximum allowable of its values. Practically in cases of high multiplicity of treatments, they are carried out as closely as possible in time, as long as they fit in the growing season.

Note: The instructions in the onion table are not valid for onions and other green onions! Their preparations with copper are not treated!

HOM and sulfur

Chloroxide copper at the time showed high efficiency in combination with colloidal sulfur. The drug Sulfur + HOM was patented in the Russian Federation, it coped with the Colorado potato beetle.

The results of field tests of Sulfur + HOM are given in Table. in fig. below. They are really impressive. Notice the sign at the bottom right: the synergy coefficient shows that XOM with sulfur can almost double the effect of each other.

Figures: results of field trials of the drug Sulfur + HOM

However, it is useless to type in the search for “Sulfur + HOM to buy” - there is no production of this tool. The formal reasoning reason is the high danger of sulfur. No less weighty - sulfur is the raw material for the handicraft production of explosives. Therefore, colloidal sulfur is currently excluded from free circulation. And, as they say, thank God - biologics against the same Colorado potato beetle are much safer and more effective.

Description of the drug:

Copper oxychloride is a chemical drug that destroys the causative agents of such diseases as late blight, rust, powdery mildew, spotting. It is effective at all stages, but shows the best results when used in the early stages of the disease and as a prophylactic agent. Once on the leaves, XOM does not allow pathogenic fungi to penetrate inside. In addition, when processing potatoes, the drug deters the Colorado potato beetle and kills its larvae.

Chloroxide copper is used for spraying plants during the growing season. Three to six treatments are performed per season at intervals of 1.5–2 weeks. The last processing is possible no later than 20 days before harvesting, for grapes the period is extended up to a month.

HOM is a good alternative to Bordeaux. The main advantage is the ease of preparation of the solution. The drug is compatible with most modern insecticides and fungicides that do not contain lime. However, it must be borne in mind that it is less resistant to washing off by rain.

Mode of application:

Copper oxychloride is produced in the form of a wetting powder, goes on sale in packages of 20 and 40 g. The recommended drug consumption rate is 30–40 g per 10 liters of water. To prepare the suspension, the green powder is mixed with a small dose of liquid to a creamy state, then, while stirring, add the rest of the water. Immediately after preparation, the leaves are uniformly moistened with a solution. The duration of the fungicidal effect is 10-14 days.

Processing should not be carried out at air temperatures above + 30 ° C, as well as in cold weather and high humidity. In such conditions, HOM, like all copper-containing preparations, burns the leaves. The use of suspensions is prohibited during flowering.

Precautionary measures:

Chloroxide copper is recognized as a moderately hazardous compound (III hazard class) for humans and low hazard for bees. Subject to the norms of consumption, the drug is not phytotoxic.

When preparing the suspension in a separate container and spraying it is necessary to wear rubber gloves, glasses, a cotton-gauze bandage. In addition, it is necessary to remove children and pets from the treatment area.

During spraying it is forbidden to drink, eat, smoke. After work, wash hands and face with soap and rinse your mouth.

In case of contact with the skin or eyes, rinse immediately with clean water. If ingested, immediately drink 0.5 liters of water and take activated charcoal.

HOM should be stored in a dry and cool place, separate from food and medicine. An expired product is not suitable for use.
