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

Taking care of plants in the garden on a suburban area requires 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 infection.

What are fungicides

A fungicide is a biological or chemical substance used to suppress the formation of fungi. It is fungi that 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 benefits include the following:

substances penetrate into 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;
the effect is on a wide range of fungal diseases.

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

As a result of disinfection, there is a partial violation of the favorable microflora, which can affect the growth and development of green spaces. If the processing of fruit plants is carried out, then it will be possible to eat the harvested crop only after some time.

Validity

The exact duration of the protective action 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 influence of drugs, there is no need to wait between sprays.

Classification

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

When choosing a suitable 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 contain no heavy metals, so they easily dissolve in liquid and can be used in combination with other substances. Moreover, they are considered unstable compounds and remain in the ground for a short time.

The inorganic variety is copper-bearing. Also, the composition may contain compounds of nickel, potassium, sulfur and other elements. They are compatible with fewer drugs and are able to accumulate in the ground and remain in it for a long period.

Depending on the action on the pathogen

According to the method of action on the causative agent, fungicides of a systemic nature and contact are isolated. Systemic substances easily penetrate into plants, move through the vessels and get into all parts, which provides reliable protection against possible infections. Some types of systemic drugs can be used for prophylactic purposes.

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

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

By application

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

Seed disinfectants. Seed handling is important for a large number of crops. The greatest efficiency is demonstrated by disinfection with combined agents.
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 phytophthora.
Fungicides for spraying perennials during dormancy. Spraying is carried out to destroy pathogens in the wintering parts of the plantings, as well as from powdery mildew and rust.
Preparations for spraying during the vegetative period. These drugs are actively used during the period of plant growth and development.

Depending on the nature of distribution within plant tissues

Local and intra-plant fungicides are isolated according to the distribution of the substance inside the tissues of the plantings. The former are active on the outer side of stems and leaves, while the latter penetrate deep into tissues and have a complex effect..

Operating principle

The specificity of the action of protective drugs depends on their category. When purchasing fungicides, it is imperative to find out the variety in order to competently process the plantings in the future.

Chemical fungicides

The mechanism of action of chemical fungicides is diverse and consists of many processes. After spraying the plants, nuclear fission 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 chemical preparations prevent the formation of nucleic acids and suppress energy metabolism.

Biological preparations

Substances of natural origin increase the immunity of plants and provoke the production of substances that prevent infection. In the case of spraying plants infected with a pathogen, organic preparations release toxins to destroy the pathogens.

Instructions for use

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

For soil

Fungicides intended for the ground in a powdery state are introduced during digging. Using natural substances dissolved in water, they shed the surface of the soil to destroy pathogenic fungi.

For plants

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

For seeds

The seeds are processed immediately before sowing. For seed treatment, it is most convenient to use soluble substances. Having wrapped the seeds in cheesecloth, they are placed in a solution and kept for the time indicated on the package.

List of drugs

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