Fungicides for flowers


Agat-25K is a biological preparation for protecting plants from diseases and increasing yields. Increases seed germination, enhances the development of the root system. It is intended for garden crops, but it is successfully used for indoor plants as a prophylactic and light fertilizer. The active ingredient is inactivated bacteria Pseudomonas aureofaciens, biologically active substances of plant and microbial origin, macro-and microelements. Available in the form of fluid paste in bottles of 10g. 1 scoop of the drug is diluted in 3 liters of water until completely dissolved, then the plants are sprayed three to four times with an interval of 20 days.

Alirin-B - a biological drug against diseases of indoor and garden plants. Contains bacteria Bacillus subtilis. Effective against powdery mildew, downy mildew (mildew), gray and white rot, late blight, anthracnose, septoria, alternariosis, cladosporia, root and stem rot, rust fungi. The consumption rate of the drug: 2 tablets per 10 liters of water for watering plants, and 2 tablets per 1 liter of water for spraying. Re-treatment after 5-7 days, up to 3 treatments in total.

Baktofit - a biological drug to protect plants from diseases, helps protect plants from powdery mildew: especially carnations, roses, delphinium, fruit and berry bushes - gooseberries and currants, when it is not possible to use chemicals. The drug is especially effective in cool weather during the period of regular precipitation, but spraying and watering should be done a day before the rain, at most, 6 hours before the rain, and repeated after 4-5 days. The drug can be used for preplant treatment of cuttings, seeds and tuber storage.

Baktofit - instructions for use, reviews, consumption rates.

Bordeaux liquid - one of the most powerful tools in the fight against fungal or bacterial diseases. For the preparation of Bordeaux liquid, it is recommended to use quicklime in the form of lumps or fluff. For the preparation of a 3 percent solution of Bordeaux liquid, 300 grams of quicklime will be required (lime is pre-quenched with water) and the same amount of copper sulfate per 10 liters of solution. Copper sulfate and lime are each dissolved in 2-3 liters of hot water in a separate non-iron pot, then the volume of each solution is adjusted to 5 liters using very cold water. Lime solution is filtered through a double gauze, and then the solution of copper sulfate is poured with a stream with constant stirring into a lime solution.

The mixture should have a beautiful bright blue color and not contain an excess of copper. Copper acts as a poison in this preparation, and lime is introduced as an acid neutralizer. If you add less lime than you need, you can burn the plant. To determine the acidity of the liquid, an iron nail is dipped into it. In the case of an acid reaction, after 3-4 minutes the iron surface is covered with a red coating of copper. With a neutral and alkaline reaction, red bloom is not formed. The reaction of Bordeaux liquids can also be set to the litmus test. When acidic, the blue litmus paper turns red, and when alkaline, the red paper turns blue.
The solution should be used on the day of preparation. During the day, you can save it by adding sugar (5-10 g per 10 l).

The given proportions of substances are high - a very strong solution is obtained, this is how it is used on severely affected plants. Usually, for indoor plants, the following proportions are recommended: 100 g of copper and lime per 10 liters of water. All the details and warnings read: Bordeaux Liquid - instructions for use

The most common fungicides in indoor floriculture

In the arsenal of each experienced grower and gardener there are fungicidal preparations in the form of an emulsion, powder or suspension. In the fight against fungal diseases of plants, they are simply irreplaceable. On sale you can find similar agrochemistry of different types of exposure. Consider the most popular fungicides for indoor plants and analyze each name in terms of the sensitivity of pathogenic fungi to it.


The drug is a organic fungicidebased on grain substrate and active soil bacteria Trichoderma lignorum, whose vital activity contributes to the suppression of fungal spores.

“Trichodermina” can cope with 70 types of pathogens of fungal diseases of plants. In particular, such as: seed infections, fusarium, macrosporosis, root rot, phytophthora, rhizoctoniosis.

The tool begins to act on contact with microorganisms, not poisoning the culture. It is distinguished by its ability to improve the fertility of the land, stimulate the nutrition of the roots, and increase the germination of the grains.

Externally, it is a light powder, which comes to be sold in packages of 10 g capacity. To disinfect indoor flowers for root lesions, the contents of the package are diluted in 1 liter of water and moistened with a suspension in a pot. And for the treatment of the aerial parts of the flowerpots, the entire preparation from the bag is dissolved in 5 liters of water. Also "Trichodermin" is recommended for prophylaxis when transplanting plants (a pinch is added to the substrate), when rooting the cuttings of Saintpaulia (slightly poured into water).

The remaining unused solution is better to put in a closed container in the cellar and store no more than 4 weeks. When re-using, wait until the product reaches room temperature.

It is a biological fungicide for plants in the garden and in a house containing bacteria called Bacillus subtilis. They affect the causative agents of fusarium, powdery mildew, gray and white rot, blight, leaf spot, keel, mildew (downy mildew).

Released "Gamar" in the form of tablets. For watering flowering and ornamental crops, 1 tablet must be dissolved in 5 liters of water, and 2 tablets and 1 l of water are needed for spraying. To achieve the desired result, disinfection is repeated throughout the week. three times a day.

Bordeaux liquid

This fungicide is in the list of the most powerful drugs against pathogenic microbes and fungi. It can be purchased in finished form, and you can cook yourself.

To do this, in separate non-metallic containers, you need to fill in with boiling water (not steep) 300 g of quicklime and copper sulphate. Then in each bowl, bring the composition to the desired volume (up to 5 liters) with cold water.

After filtering the mortar through the gauze folded in several layers, slowly add to it the contents of the second dish. The result should be a bright blue 3% mixture with active copper and acid neutralizing lime.

Be careful: non-observance of proportions will harm plants. For example, if you donate lime powder, the flowers after treatment with this remedy will get severe burns. The above ratio of components is intended for volumetric foci of infection. At the initial stages of the disease, it is recommended for vases to prepare Bordeaux liquid in a ratio of 100 g: 100 g: 10 l.

If the solution remains after treatment, it can be stored for 24 hours by adding a teaspoon of sugar (per 10 liters).

Acts on parasites contact and systemic. Available in the form of a white or yellowish 15% soaking powder with parallel names “DuPont Fungicide A”, “Aspor”, “Tiudou”, “Ditex”, “Novozir”, “Zineb”.

The fungicide is intended for spraying the aerial parts of plants and affects the pathogens for 2 weeks, does not suppress the reproduction of powdery fungal spores.

It interacts well with organochlorine and organophosphorus substances, but it should not be mixed with Bordeaux liquid.

A biological fungicide designed to combat parasitic fungi and bacteria. Its main constituents are microorganisms. Bacillus subtiliswhich resist well to causative agents of powdery mildew, late blight, stem and root rot, Alternaria, mildew, anthracnose, rot, septoria, cladosporia, rust.

It is released in the form of tablets. For processing of underground parts of plants, 2 tablets are placed in a bucket of water, and for spraying the stems and branches - 1 l of water and 2 tablets of "Alirina" are enough. For severe infections, it is recommended to repeat disinfection in a week. The maximum number of treatments - 3.

Is a biological product of anti-fungal and antibacterial action. After its use, there is an increase in yield on vegetable crops, an increase in seed germination and the development of a powerful rhizome.

For these qualities, gardeners fell in love with gardeners, but with success it is used as a preventive agent and as a fertilizer gardener.

The active substance "Agatha" are microorganisms. Pseudomonas aureofaciens. The drug goes on sale in 10-gram bottles with fluid paste. The working solution is prepared from the calculation of 3 liters of water per 1 scoop of fungicide. Processing of the pots obtained composition is made three times with a 20-day interval.

Processing can be carried out by foliar and root methods. In addition, it is recommended to use "Fitosporin" for soaking seed, rhizomes of seedlings during planting, protection of flower tubers and bulbs when laying in the cellar for the winter.

This biological product is also an antidote, fungicide and growth stimulant.

Agronomists recommend it for the restoration of plants after herbicidal stress, prolonged droughts, hailstorms, during various fungal lesions, with poor germination of grains and low yields. The drug does not have a toxic effect on vases and people. With the aim of preventive and therapeutic measures it is used for root rot, bacteriosis, leaf spot. The active substance "Albit" does not cause addiction in pathogens. Very effective to use for indoor plants.

"Albite" can be added when watering vases. To do this, 1-2 ml of the drug is diluted in 10 liters of water. Root processing is carried out in such a way that the tool falls on the foliage of the culture. To soak the seed need 5 ml of fungicide dissolved in 1 liter of water.

Potassium permanganate

Among agrochemists, this drug is called potassium permanganate, or potassium permanganate. It is used in many spheres of human activity, and in plant growing it is referred to as fungicidal agents, which are used for moistening seedlings, seedlings and adult cultures during infections with fusarium, black leg and bacteriosis.

Also, the drug is recommended for soaking seeds and disinfecting garden tools.

Active ingredients of potassium permanganatemanganese and potassium. Getting to the roots, trunk and leaves, they contribute to the rapid growth of flowers and create a reserve of their strength, resistance to attacks of diseases and pests. To process the grains, it is enough to dip the material into a solution of 0.5 g of potassium permanganate and 100 ml of water for 20 minutes. After the procedure, the grain must be washed with clean water and dried.

To disinfect the soil from nematodes and various bacteria, fungi that provoke the appearance of black legs and phytophtoras, 5 g of potassium permanganate crystals in 10 liters of water should be diluted. And for feeding plants suitable solution of 3 g of the substance and 10 liters of water. To save foliage from powdery mildew, 3 g of potassium permanganate is dissolved in 1 bucket of water and 50 g of potassium nitrate is added to it. Prepared by means of spraying the aerial parts of crops.

Contact fungicide actions

When using these drugs, their penetration inside the plants is excluded. They cover the outer part of the plant, if there are reproductive and vegetative organs on the surface of the fungus, they are suppressed. All drugs act for a different period, which is determined by the duration of the solution on the surface of the plant. The best results can be achieved if processing at least 3-5 times at intervals of 10-12 days.

A feature of contact fungicides is the local nature of the impact. They are not used to treat affected plants, they are designed to suppress pathogens located on the surface or directly in plant tissues. Due to the fact that these fungicides are not able to spread to other parts of the plant, such treatment before the formation of the fruit prevents their penetration.

Systemic preparations act a little differently: as a result of processing, they penetrate into the internal organs of the plant, spread through the tissues, making changes in the physiological and biochemical processes occurring in the organs of plants. As time goes by, their decomposition inside plantsthat ends with the formation of metabolites. In this state, they begin to have a depressant effect on the harmful fungus.

It is believed that decomposition products, which are formed inside the plants, are more harmful than the drug itself. In order to avoid possible complications, it is best of all to carry out processing in vegetable gardens and in private farms with the help of chemical preparations of precisely contact action. At the same time, the deadline for their use is the period when one month will remain until harvest.

Types of fungicides and methods of their application

In stores for gardeners fungicides are offered in various forms: in the form powder, suspension, emulsions, well soluble in water.

Depending on the composition, the following types of fungicidal drugs are distinguished:

  • Inorganic. Within this group, drugs of classes 1–4 of danger to humans and warm-blooded creatures are isolated.
  • Organic The main component in them are active microorganisms that inhibit pathogenic fungi.

More preferred for use on the suburban areas biofungicides, because in addition to high efficiency, they cause minimal damage to plants.

Chemical fungicides

Often, gardeners buy new products for effective pest control, especially if they provide high efficacy with a small dose of use. However, doing so is wrong. You can expect good results only if you use proven drugs. Within the group of chemical fungicides that proven effective when used for protection during the growing season of various garden crops, the following can be distinguished:

  • Bordeaux liquid
  • copper sulphate,
  • abiga-peak, sun,
  • oxy
  • zineb,
  • Thiram
  • potassium permanganate (manganese),
  • soda ash using adhesive (soap green).

Biological fungicides

In recent years, many biological contact fungicides have appeared on the market. In their manufacture using a slightly different approach than in the case of chemicals. The main component of biofungicides are active bacteria, whose activities have a depressant effect on the causative agents of fungal diseases.

The use of contact biofungicides is more preferable, since they do not cause or cause minimal harm to humans, warm-blooded animals, fish and bees. Consumers who are going to use biofungicides at home should pay attention to the following types of drugs:

  • Hamair P,
  • Trichodermin,
  • alirin B,
  • albite,
  • phytosporin,
  • baktofit,
  • agate,
  • planzir,
  • barrier and others.

Treatment with chemical fungicides of contact action can only before flowering and after harvesting. The advantage of biofungicides is that they can be used throughout the growing season. At the same time, there are such products on sale that can be used at the stage of crop maturation. It should be borne in mind that the drugs of contact action are effective in the prevention. If the drug reaches the causative agent of the disease, then this leads to his death. If the plants are already affected by the disease, then they cannot be saved with the help of these drugs.

Rules for working with contact fungicides

Прежде чем использовать фунгицид, необходимо позаботиться о собственной безопасности: для этого нужно подготовить закрытую одежду, резиновые перчатки и очки и головной убор. After processing, clothes are sent to the wash, and hands and face should be thoroughly washed with soap and water.

It is necessary to carry out processing of plants in advance prepared solution. The exception is when the instruction prescribes the use of fresh composition.

In the process of preparing a solution for the treatment of plants, it is necessary to strictly follow the recommendations specified in the instructions, maintaining the optimum consumption rate taking into account the phase of plant development.

It is possible to use fungicides in the most favorable conditions for this: in the early morning or in the evening, provided that it is worth dry windless weather.

For the sprayer, you must select the mode of operation for fine spraying. The solution cloud coming out of it should flow onto the plants from below and above.

It is forbidden to use chemical fungicides in relation to those plants whose green parts of the above-ground mass are to be consumed. For safety reasons, all crops should be processed before the flowering and fruit set phase.

It is impossible to clean the dishes, in which the solution was prepared, in reservoirs. Disposal of used pesticides should be done only in specially designated areas.

The place where it is supposed to store fungicides and other drugs with a chemical composition should have limited access. Drugs must be placed sealed.
