In the “struggle” for the harvest, farmers have to deal with various pests and plant diseases. One of the popular drugs is Ordan, which has shown its effectiveness in the fight against late blight, powdery mildew and peronospora. According to the owners of dachas in the regions of Russia, the use of fungicides makes it possible to protect plantings from diseases and save crops from insidious infections.
Carefully follow the instructions for use, observe the dosage of the drug, and the result will definitely be achieved.
Description of the drug
The manufacturer of the fungicide is Russian, known for its preparations for plant protection in household plots, as well as in agricultural production.
The company's catalog contains 110 products from various groups, including herbicides, pesticides, fungicides, and adjuvants. Wettable powder Ordan (Ordan) is intended for preventive spraying and treatment of vegetable crops against dangerous diseases, such as:
- late blight;
- Alternaria blight;
- peronosporosis.
The composition contains two active ingredients:
- copper oxychloride (external action);
- cymoxanil (internal).
Oxide remains on the surface of the leaves, blocks the mineralization of organic substances in fungal spores, contributing to the death of pathogens. The effect of cymoxanil is different, since this substance penetrates plant tissue, destroys fungal spores in the internal structure and at the same time participates in the regeneration of damaged cells.
These two components determined the complex action of Ordan:
- disease prevention;
- inhibition and destruction of pathogens;
- treatment of infected areas.
Duration of action:
- for prevention - 1-2 weeks;
- during treatment - 2-4 days.
Packaging
The manufacturer offers convenient packaging of the fungicide - sachets of 12.5 and 25 g, which allows you to treat small areas, greenhouses and hotbeds. For large farms they are produced in packages of 1 and 3 kg, bags of 15 kg.
To increase the accuracy of dosing and avoid direct skin contact with the substance, special water-soluble bags are used for the Ordan fungicide.
The drug has the form of a wettable powder, which, after dilution with water, turns into a suspension. This form of solution is best preserved on the leaves and trunk of plants.
Reviews from gardeners
- Mikhail 38 years old, Volgograd. In humid climates, tomato diseases develop very quickly. Without the use of fungicides it is impossible to get a good harvest. To process greenhouse vegetables, I regularly use Ordan, which destroys pathogenic microorganisms.
- Maria 28 years old, Krasnodar. Previously, I constantly lost part of the harvest due to late blight, which affected vegetable crops. To prevent infection, I started using Ordan. However, processing conditions must be taken into account. Read the instructions carefully before using the drug.
- Olga 45 years old, Yoshkar-ola. Late blight is a dangerous disease that affects potatoes and tomatoes. Folk remedies do not always help cope with the disease. To process vegetable crops I use Ordan, which is capable of quickly destroying harmful bacteria. Now I regularly get a good harvest even in such difficult climatic conditions.
Composition and principle of operation
The drug "Orda" refers to inorganic fungicides. Its characteristic feature is its complex effect on the infection, since the product contains several active substances. One penetrates deep into the plant, kills the pathogen and heals damaged cells, while the other provides protection, remaining on the surface, stopping the development of fungal spores. Manufacturers produce two types of pesticides. They have different designations, purposes and composition, but the described principle of operation is the same.
Ordan SP is approved for use on private farms. It consists of copper chloride (CHOM) and cymoxanil, which is less toxic (hazard class for bees and humans - 3). Release form: wettable powder. Sold in bags of 12.5 and 25 g, in boxes of 1 kg.
Ordan MC is intended for use on farms and peasant farms, in agricultural fields. It has a class 2 hazard for humans, class 3 for bees. This change in toxicity occurred when HOM was replaced by mancab, a dithiocarbamic acid derivative, to make it easier to treat large areas. It is also available commercially in powder form, but in larger packages starting from 2 kg.
When purchasing a fungicide in a commercial network, you must carefully study the label, since treating your garden plot with a more aggressive drug can result in negative consequences.
Active substance and release form
The manufacturer of this product is (Russia), which produces the famous fungicide “Topaz”. It contains 2 active substances - copper chloride in the amount of 689 g per 1 kg and cymoxanil 42 g per 1 kg. The fungicide is available in powder form, packaged in 1 kg cardboard boxes and 15 kg bags.
According to the method of penetration, Ordan belongs to contact and systemic pesticides, and according to the nature of action - to protective and medicinal fungicides.
Precautionary measures
- Ordan belongs to the group of drugs with moderate toxicity. It corresponds to hazard class 2-3. If the solution gets into the stomach, inflammation may begin.
- During processing, it is necessary to protect the eyes and respiratory tract.
- Before using Ordan, you should carefully study the instructions.
- Spraying in sunny weather can cause burns.
- Before spraying, you must wear protective clothing that will cover all exposed parts of the body.
- Be sure to use goggles and a respirator.
- Hands are protected with rubber gloves.
- Do not drink water or smoke during treatment.
- If the solution gets on your skin, wash it off with water.
From what diseases
Thanks to the contact and systemic action of the drug, the use of Ordan fertilizer strictly according to the instructions provides double protection of vegetable, ornamental and berry crops from a number of diseases:
- late blight;
- peronosporosis of cucumbers;
- Alternaria (mold);
- powdery mildew (oidium, mildew);
- cladosporiosis.
Ordan fungicide works most effectively when applied in the early stages of the disease, before the first symptoms appear. It is not addictive and maintains the sensitivity of pathogens to active substances. Thanks to the fungicide, the intervals between treatments when growing cucumbers and tomatoes, potatoes, onions, strawberries, grapes, roses, indoor plants and ornamental plants become longer than when using other drugs.

Both active components, acting simultaneously, are able to prevent the penetration of fungi and their spores into plant cells. Ordan treats diseased garden and vegetable crops and can suppress and kill various pathogens.
However, its effect on the infection lasts no more than 6 days after treatment, and if Ordan is used as a prophylactic agent, then its period of action is 1-2 weeks.
Purpose
The fungicidal drug Ordan acts in three directions: it destroys fungal spores, restores the cells of garden crops, and is also used for preventive purposes. Fungi can affect fruit trees, vegetables, berry bushes, and flower beds. It is to combat them that fungicides are used (from fungus, i.e. mushroom and caedo - to kill). There are a huge variety of fungi, and, depending on their type, garden crops develop one or another disease. Ordan instructions for use:
Vineyards
Grapevines are susceptible to mildew and late blight. Ordan is an excellent choice for a gardener to combat these diseases. For prevention, the drug is used during the growing season; in the spring, each vine should be treated with a three percent solution; in the autumn, after harvesting, the treatment is repeated. If the vines are already infected, it is necessary to treat them at least three times with a break of ten days.
Tomatoes
Brown rot is a type of fungal disease that can affect young tomatoes.
To avoid infection, it is enough to follow simple rules: when the tomato seedlings have already taken root in the greenhouse or open ground (about twenty days after planting), you need to spray the seedlings with Ordan's solution. The second time the treatment is done in August, since rains and temperature differences (night and day) can lead to a recurrence of brown rot. If the plant is already infected, you can try to cure it by spraying it at least five times, about once a week. If the tomato cannot be cured, the plant should be removed and destroyed, and the soil should be disinfected.
cucumbers
Powdery mildew is a dangerous disease that can destroy cucumber seedlings. The spores of these fungi are very persistent and can persist in the soil for several years. Mildew affects cucumbers regardless of the development phase. The reasons are high humidity, cold precipitation, temperature differences between day and night, a large amount of condensation on the greenhouse film, incorrectly applied fertilizers, etc. As soon as signs of this disease appear, the following measures should be applied:
- Stop fertilizing and greatly reduce watering
- In cold weather, provide cucumbers with additional insulation with film or other material
- When the humidity is reduced, the plants should be treated with Ordan's solution, and this spraying should be carried out at least three times, an interval of seven days.
- When the harvest is harvested, spray the plants well, and after a day remove them with the rhizomes and disinfect the ground.
Flower crops
Garden flowers can be affected by rust. It is easy to identify - orange spots appear on the stem and leaves, the leaves dry out and fall off. In this case, Ordan will also help. It is necessary to treat each bush with the working solution of the drug at least three times, the interval is ten days.
Instructions for use
The working composition is prepared before direct use, acting strictly in accordance with the instructions. The mixture must be mixed, shaken well, repeating this action from time to time during spraying.
Spray the leaves and stems of plants so that the product moisturizes the surface well. Aqueous solutions are not suitable for storage, so they are all dispensed on the day of preparation.
Working solution for spraying:
- potatoes and tomatoes against late blight - 25 grams of the product are diluted in 5 liters of water;
- cucumbers against peronosporosis - 25 grams of the drug per 8 liters of water.
The proportions must be observed exactly, otherwise, at a lower concentration, cymoxanil will not work; at a higher concentration, the medium will be alkaline due to copper chloride.
Handle plants wearing thick protective clothing, a mask or respirator, and gloves. If the solution gets on your skin, rinse the area immediately with cool, clean water. If accidentally swallowed, drink large amounts of water while attempting to induce vomiting. Then take activated charcoal and contact your doctor.
For tomatoes (in a greenhouse, open ground)
With high humidity and large temperature changes, tomatoes are often infected with Alternaria and late blight. As noted in the instructions, Ordan carries out the prevention of these diseases both in the tomato greenhouse and in the open ground. It should be noted that the first spraying should not be done immediately after planting; it is necessary to allow the plants to take root and strengthen for about three weeks. Then, at intervals of 7-10 days, the procedure can be repeated. As a treatment, Ordan on tomatoes is effective only during the first two days.
For grapes
A fungicide is used to prevent powdery mildew. This infection is dangerous for grapevines, causing great damage to plantings.
Ordan is used in the early stages of the disease using a standard solution (25 ml of product per bucket of water). Usage per cell is 6 liters, the total number of procedures is three times.
There should be a two-week break between treatments, but do not use Ordan during the period of budding and flowering of the grapevine.
The first spots of powdery mildew appear on the underside of the leaf. Therefore, during processing it is necessary to lift the leaves and thoroughly wet them on both sides.
For cucumbers (in a greenhouse, open ground)
The drug "Ordan", according to the instructions for use, is used for the prevention and treatment of cucumber diseases such as downy mildew. Both gherkins that grow in greenhouses and greenhouses, as well as those in open ground, are treated. Prevention with fungicides is carried out after the plants have rooted and the first 6 leaves appear, but before flowering. The next spraying is carried out after 7-10 days.
For roses
Roses are delicate plants and are susceptible to fungal diseases. In the prevention and treatment of the initial stages of rust and peronosporosis, flower growers successfully use the Ordan fungicide. For this, a highly concentrated solution is used in the ratio: 5 g of the drug per 1 liter of water. One bush requires no more than two liters of working solution; the stems and leaves are treated on both sides. As in the case of vegetable crops, it is recommended to spray flowers no more than three times per season.
Treatment of other garden flowers
Ordan is excellent for combating the first signs of mold and rust on roses and other garden flowers.
As soon as you notice the first signs of the disease on the stems or leaves, you need to dilute 25 g of Ordan powder in 5 liters of water. One bush accounts for about 15 liters of finished product.
The plant will begin to recover within 3-4 days; 2-3 treatments are necessary to completely destroy the fungus.
For strawberries
The insidious pathogens of brown spot and gray rot are capable of thwarting all the efforts of gardeners and destroying the harvest. Treatment with Ordan will help: per hundred square meters of bed you need 5 liters of the prepared solution. Not only the strawberry bushes themselves are sprayed, but also the surface of the soil around them and the row spacing.
For the bow
Used against powdery mildew. Processed greens are not cut into feathers.
Bulbs can be dug up 21 days after the last spraying.
For potatoes
The working solution for spraying potatoes is prepared in the same way as for spraying cucumbers and tomatoes, i.e. 25g:5l. If you want to treat the crop as a preventive measure, then this is done before the tops appear in the rows. If the potatoes are already infected with fungi, the plant is treated 2 days after signs of the disease appear.
Subsequent procedures are carried out after 7 days. Harvesting can be done no earlier than 3 weeks after the last spraying. The maximum number of procedures is 3.
Use 5 liters per 100 m2.
For indoor flowers
The use of Ordan fungicide is not recommended in residential areas. If necessary, plants are sprayed outside, taking the pots out into the open air.
Working solution: 1 gram of powder per liter of water. Carry out the treatment according to the recommendations, no more than three times, with a mandatory interval of 10-12 days.
Impact speed
Depends on the crop being sprayed and the amount of substance spent on treatment per unit area.
- In vineyards, when they are affected by mildew fungus, the spraying rate is 1 sq. m of culture is 25 - 30 ml of Ordan's solution.
- For cucumbers and tomatoes in case of damage by late blight, alternaria and downy mildew, a volume of 30-32 ml of solution per 1 sq.m. is used for treatment. planting areas.
- And to prevent peronosporosis in onion beds, you need to treat it using aerosol spraying in an amount of 23 ml per sq. m. area sown with onion sets.
With this degree of exposure, the effect of Ordan will appear within 3 days, although bacteriological analysis shows the destruction of spores on treated surfaces within the first 2-3 hours. The rest of the time is needed to influence the deep layers of the cytoplasm under the outer protective shell and treat tissues affected by fungi, if this is still possible.
Not every type of fungal infection can be treated, and it is not always possible to completely get rid of the consequences of infection.
Therefore, the postulate that it is easier to prevent than to treat is 100% correct when using Ordan.
The protective effect of the fungicide lasts on average 30 days, which makes it necessary to treat areas approximately three times during the entire growing season. The drug is insensitive to precipitation, so there is no fear that it will be washed off from the leaves of crops treated with it.
Treatment of plants is also stopped at different times in anticipation of harvesting. The final treatment of potatoes should be done at least 29 days before the planned harvest date, that is, around the beginning or middle of September. For cucumbers in open ground, the last spraying is done a week before the start of harvesting, and if they were cultivated entirely in greenhouses, then in conditions of elevated temperatures, the harvest can be harvested within two days after treatment.
How to make treatments safe and effective
- When watering, use personal protective equipment: gloves, mask, safety glasses.
- For spraying, choose morning or evening time, this will help avoid burns on the leaves.
- To avoid poisoning, do not perform manual work in the garden earlier than 5-7 days after treatment.
- In windy, rainy and too hot weather, the effectiveness of fungicides is reduced. At a temperature of 26-28º C it evaporates faster than it is absorbed.
- Apiary for fungicides - no closer than 1.5 km, residential buildings - 15 m, playgrounds - 150 m, people without security - 50 m.
What can be mixed with, compatibility with insecticides
Ordan is compatible with most fungicides, pesticides, insecticides and fertilizers. The most important thing is that the accompanying product has neutral acidity or low acidity. Mixing Ordan with alkaline compounds is strictly prohibited. As a result of mixing, part of the active substances precipitates, and the mixture does not have a therapeutic or protective effect on plants.
Before mixing drugs, perform a compatibility test. Stir one drop of the prepared solution in a glass of water. If no sediment appears in the container, and the color, temperature and smell remain unchanged, they can be used simultaneously.
Ordan's analogues
On the fungicide market you can find analogs of Ordan; they will not have such a comprehensive effect as it, but are also effective in combating plant diseases:
- HOM – contains only copper oxychloride;
- Oxychom - contains copper oxychloride paired with oxadixil;
- Kurzat;
- Abiga Pik - the fungicide is based on copper.
Toxicity
Ordan has a hazard class of 3 for humans and warm-blooded animals, that is, it is a moderately dangerous substance. For bees, it has a hazard class of 2. This means that it cannot be sprayed during mass flowering. In other cases, treatment should be carried out early in the morning or after sunset, when bees are not flying. Ordan is practically harmless to birds. However, spraying near fishing waters is prohibited.
In treated plants, Ordan components are quickly destroyed and do not accumulate. In solutions, the half-life is 2 days, in garden soil - 2 weeks, in greenhouse soil - up to 3 weeks. The components do not migrate into groundwater and do not suppress soil microflora. Completely under the influence of soil microorganisms, the remains of the drug decompose from 1 to 6 months.
First aid
The following instructions are intended to provide FIRST aid only, after which you should immediately consult a doctor and follow his instructions! DO NOT TREAT YOURSELF !
- If the drug gets into the gastrointestinal tract, you should drink crushed activated carbon in the amount of 1 g per 1 kg of body weight with several glasses of water and induce vomiting. Then drink the same mixture again, but do not induce vomiting.
- If the drug gets on your skin, remove it with a cloth or cotton wool, being careful not to rub it, and then rinse the area with a weak soda solution or running water.
- If fungicide vapors enter your lungs, leave the area and change clothing.
- If Ordan gets into your eyes, rinse them with clean running water for 10 minutes.
- After providing first aid, consult a doctor immediately!
Advantages and disadvantages
The main “advantage” of this drug is its ability to suppress the most common and dangerous diseases, which reduces crop losses.
Benefits also include:
lack of pathogen resistance to the drug;
complex effect on plants;
no plant inhibition;
universal use (effective on vegetables, berries, ornamental plants);
low toxicity to humans, subject to compliance with all rules of use.
Ordan's active substances are completely broken down and removed from the soil during the season; they do not accumulate in the soil.
Product Disadvantages:
toxic to fish (processing near water bodies is prohibited);
large packaging is inconvenient to use and store;
Large scale processing requires large quantities of powder.
It is considered a focal drug, so it produces effects in areas that do not have chronic pathogen damage.
Features of use
Cymoxanil is able to penetrate inside the plant within an hour, which explains its high resistance to washout by rain. The mechanism of action on fungi is based on suppression of RNA synthesis in cells. To prevent pathogenic organisms from developing resistance to the drug, copper oxychloride is added to the composition. This substance itself has a strong bactericidal effect. After processing the grapes, the saturation of organic compounds with minerals is blocked; as a result, the spores do not receive nutrients and die.
The product is considered relatively safe for living organisms. After the decomposition process in the soil is completed, the drug will play the role of microfertilizers. To save labor costs and increase the efficiency of treatments, Ordan can be combined with various chemicals that do not have an alkaline reaction.
To avoid mistakes, the manufacturer recommends mixing the components for the tank mixture in small volumes first. If there is no sediment, the resulting solution can be used for its intended purpose according to the instructions.
