In a rainy summer, a large number of diseases can be found on plants. But you always want to get a good harvest of fully ripe fruits. Growers go to a specialty store to purchase chemicals and fungicides to protect their crops, including tomatoes.
Often the choice is made in favor of the products recommended by the sellers themselves. But not always with their help it is possible to achieve the desired results. The bushes continue to wither and die before our very eyes. To avoid such troubles, you should be well versed in fungicides that can create reliable protection.
These drugs are great for fighting with bacterial diseases and fungi... They are constantly being improved by plant protection specialists, who develop new drugs, taking into account the immunity of garden crops.
In the process, a large selection of fungicides is formed, from which it is rather difficult to choose the most effective formulations. For this, it is recommended to know the types of drugs and the peculiarities of their use.
Fungicidal preparations by their origin and composition are divided into:
There are groups of drugs by objects of application:
All fungicides are distributed according to the principle of influence:
By their type and level of effect, fungicidal ones are simple and combined. The second group is able to work together with other fungicidal agents, insecticides, fertilizers, retardants.
These protective drugs affect pathogenic elements in several ways:
Seeds are processed in summer or autumn season after collecting and drying... They can be pollinated with dry powders, soaked in solutions or suspensions, covered with a mixture that forms a thin film, and drageeted.
Plant seedlings and tubers are best processed in spring, just before planting.
Perennials are best during the dormant season process on "bare" trunks... This procedure is performed in autumn or spring days, when there is no foliage on the plants, and the buds have not yet activated to grow.
In greenhouses, the soil composition must be processed in the fall, when harvesting is done. With the help of fungicidal preparations, disinfection of soil and organic residues... If you apply fungicidal agents on the eve of planting, it will slow down growth and extend the growing season.
Features of processing vegetative crops:
To avoid the formation of resistance to systemic formulations, it is recommended to alternate the drugs.
For indoor plants, treatment with fungicidal agents is carried out in order to improve their immunity, in case of diseases or risks of infection. When replanting a culture, the substrate is moistened with solutions of biological fungicides or low-toxic chemical compositions.
Fungicides that can provide effective assistance in the fight against diseases include the following drugs.
Quadris is a new systemic remedy with a wide range of effects that can protect plants from many diseases. It belongs to a new class of funds - strobilurins.
The composition, barely hitting the foliage, suppresses painful pathogens. Its effect helps to stop the spread and development of infections in the beds. The drug is able to reliably protect cultures from powdery mildew, late blight, downy mildew, spotting etc.;
Today it is used from phytophthora more often. The tool is especially popular in the southern regions of the country. Fungal bacteria have not yet been able to acquire resistance to this agent.
The systemic and contact action of Ridomil will perfectly help against pathogens late blight and alternaria... The granules of the product are convenient to use, they do not generate dust. The composition is perfectly compatible with many pesticides.
A biological agent intended to protect against diseases, stimulate seeds and plants during their growing season, improves the immune system cultures.
Contact agent recommended for use before planting to protect the crop from rot... It helps to preserve the harvest.
The drug is systemic and contact action. It is realized in the form of a wetting powder composition of white color, has a faint odor of irritating effect.
Contact action tool, proven over the years. Perfectly protects tomatoes from fungus... In addition, the composition effectively helps in the fight against the most common diseases.
As you can see, there are really a lot of fungicidal preparations. But only your personal experience in growing tomatoes in specific conditions on fertile soil will reduce the burden of "medicinal" nature and get an excellent harvest of tomatoes.
Tomato anthracnose is a fungal disease that can destroy already adult plants along with the fruits. Even a mild lesion, when only 1–2 leaves and their petioles are affected, leads to a decrease in yield by 45–50%. The earlier treatment is started, the less losses will be. Better yet, get it done in advance.
Many summer residents are afraid to plant large tall varieties in the garden. Even southerners prefer to choose low tomatoes for open ground that do not require pinching, yielding a crop very early in order to get away from late blight. For them, resistance to this disease of tomatoes with large fruits is a matter of paramount importance.
Residents of the Middle Lane used to have to measure their desires with their capabilities. Large determinant or indeterminate tomatoes simply did not have time to ripen, since their brushes begin to tie over 8-9 or 10-12 leaves, respectively. They were planted only in greenhouses and greenhouses.
Now a number of varieties of Siberian selection have appeared, including those with large fruits, intended specifically for areas of risky farming. Moreover, these tomatoes give a good harvest, and the taste is not inferior to the southern ones.
Siberian variety by V. N. Dederko, included in the State Register in 2006. Determinant, ripening period - medium, salad designation. Bread Salt is recommended for open ground, where it grows to a height of 80 cm.

Tomato Pink honey bred by O. V. Postnikova and V. N. Dederko, included in the State Register (2006). Determinant, mid-season, undersized variety with large (up to 1.5 kg) fruits. They are crimson, resemble a truncated heart (see photo), with a great honey taste.
The bush is slightly leafy, 60-70 cm high. Nevertheless, it requires a garter and formation of 2-3 stems. When growing record-breaking fruits, the tomato is led into 1 trunk.
To understand how to pinch tomatoes, you need to understand what stepsons look like and where they most often begin to form. After all, not everyone knows exactly which shoots need to be removed in order to improve productivity.
The stepson is a shoot that begins to form from a bud located between the stem of the bush and its leaves. The growth of this shoot is not limited in any way. Over time, flowers, leaves and even fruits will begin to form on it. It is imperative to pinch tomato seedlings with such extra shoots, since a bush that is too thick does not bear fruit well. Leaves are also sometimes trimmed. However, this will not help to completely stop thickening of the plants. Only a complete pinching of the tomatoes will help in stopping thickening. It is recommended to do this when the plant grows to 50 cm, and the length of the shoots will reach 5-8 cm.
Large varieties of tomatoes attract with their yield and large weight (from 300-800 g). These include:
Tomato variety "Brown sugar"
