Description of the 24 best fungicides for the garden, mechanism of action and instructions for use

When caring for plants in a garden in a suburban area, you need to practice an integrated approach. An important point of care is the use of protective fungicides for the garden. Special products protect green spaces and reduce the risk of infections.

What are fungicides

A fungicide is a substance of biological or chemical origin used to suppress the formation of fungi. Fungi are the causative agents of many infections that affect vegetation. Without a protective substance, plants lose their immunity, wither and develop slowly.

Advantages and disadvantages

Fungicides used in the garden have a number of positive characteristics. The main advantages include the following:

• substances penetrate inside plants in a short period and have an active protective effect;
• due to their resistance to moisture, fungicides are not washed off with water even in heavy rain;
• after treatment, pathogens are eliminated in all tissues;
• influence on a wide range of fungal diseases.

In addition to the obvious advantages, the drugs have several disadvantages.

As a result of disinfection, a partial disruption of the favorable microflora occurs, which can affect the growth and development of green spaces. If fruit plants are processed, the harvested crop can be eaten only after some time.

Validity

The exact duration of the protective effect depends on the specific type of drug used. The average is 10-12 weeks, after which re-treatment is required. Since the vegetation does not develop resistance to the effects of drugs, there is no need to wait between sprayings.

Classification

Depending on a number of characteristics, fungicides can be divided into classes.

When choosing the appropriate option, you need to take into account the condition of the plants, the presence of fungal diseases and signs of their manifestation, as well as other factors.

Depending on chemical properties

According to this indicator, fungicides are classified into organic and inorganic. The former do not contain heavy metals, so they easily dissolve in liquid and can be used in combination with other substances. However, they are considered unstable compounds and remain in the ground for a short time.

The inorganic variety is copper-containing. It may also contain compounds of nickel, potassium, sulfur and other elements. They are compatible with fewer drugs and can accumulate in the ground and remain there for a long period.

Depending on the effect on the pathogen

Based on the method of influencing the pathogen, systemic and contact fungicides are distinguished. Systemic substances easily penetrate into plants, move through blood vessels and enter all parts, which provides reliable protection against possible infections. Some types of systemic drugs can be used for preventive purposes.

Contact fungicides interact with the pathogen only on the visible part of the plantings, without penetrating into the tissue. This allows you to destroy pathogens at the stage of their development and provide protection against gray mold, anthracnose and a number of other diseases.

To achieve the effect, you need to carefully treat the plants so that the solution gets to all parts.

By purpose of use

Medicines for fungal diseases are divided into several types, taking into account the purpose for which they are used. The following groups are distinguished:

1. Seed protectants. Seed processing is important for a large number of crops. Disinfection using combined agents demonstrates the greatest effectiveness.
2. Means for disinfection of greenhouse soil. They are used to protect annual crops grown by seedlings. Fungicides of this group also help get rid of late blight.
3. Fungicides for spraying perennials during the dormant period. Spraying is carried out to destroy pathogens in wintering parts of plantings, as well as powdery mildew and rust.
4. Preparations for spraying during the growing season. These drugs are actively used during the period of plant growth and development.

Depending on the nature of distribution within plant tissues

Based on the distribution of the substance within plant tissues, local and intraplant fungicides are distinguished. The former are active on the outside of the stems and leaves, while the latter penetrate deep into the tissues and have a complex effect.

Operating principle

The specificity of the action of protective drugs depends on their category. When purchasing fungicides, you must definitely find out the variety in order to properly treat the plantings in the future.

Chemical fungicides

The mechanism of action of chemical fungicides is varied and consists of many processes. After spraying plants, nuclear division in fungal cells is suppressed, metabolic products are formed that act as an antibiotic, and areas of necrosis are formed, which serve as a barrier to the entry of pathogens into uninfected tissues.Certain elements of chemicals interfere with the formation of nucleic acids and suppress energy metabolism.

Biological drugs

Substances of natural origin increase plant immunity and provoke the production of substances that prevent infection. When spraying plants infected with a pathogen, organic products release toxins to kill the pathogens.

Instructions for use

The process of using fungicides depends on the object being treated. To achieve the desired effect, you should read the instructions for use.

For soil

Powdered fungicides intended for soil are applied during digging. Using natural substances soluble in water, they spill over the surface of the soil to destroy pathogenic fungi.

For plants

Fungicides for flowers and trees can be used by spraying or dusting. As a rule, green spaces are treated with liquid copper-based substances. Broad-spectrum drugs are used several times during the season. As a rule, processing periods occur in early spring and late autumn.

For seeds

Seeds are treated immediately before sowing. It is most convenient to use soluble substances for processing seed material. After wrapping the seeds in gauze, they are placed in the solution and kept for the time indicated on the package.

List of drugs

When choosing suitable fungicides for use in the garden, it is recommended that you familiarize yourself with the list of the best options. Each of them has individual characteristics and features.
