7 best fungicides for greenhouse and outdoor tomatoes


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.

The use of fungicides for tomatoes in the greenhouse and open field

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:

  • chemical inorganic (containing copper, sulfur, iron compounds, salts and other elements);
  • chemical organic (phthalimides, carbamates, morpholines, triazoles, strobilurins);
  • biological compositions for plants (from fungus, from bacteria, from plants).

There are groups of drugs by objects of application:

  • for dressing seeds and sowing material;
  • antiseptic compounds and antibiotics for substrates;
  • for processing perennial plants during dormancy;
  • compositions in the growing season.

By destination:

  • prophylactic agents;
  • immunizing;
  • of a therapeutic type, which are excellent in the first three days with a disease.

All fungicides are distributed according to the principle of influence:

  • contact - they cover all the bushes, acting as a kind of barrier;
  • systemic - through the integument they enter the conducting systems of cultures, circulate inside along with the juices.

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:

  • destroy the respiratory centers;
  • perform sterilization of microorganisms, block nuclear fission;
  • stimulate cultures to produce antibiotics and phytoalexins;
  • create necrotic barriers that protect unaffected plant tissues;
  • neutralize toxins of bacteria and fungi;
  • destabilize cell membranes by suppressing the production of ergosterol;
  • interrupt the process of synthesis of acidic compounds of the nucleic group;
  • upset the energy metabolism.

How to apply correctly

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:

  • the seedlings are protected and strengthened if you use the chemical compositions of the biological or immunizing group for contact and systemic effects;
  • the timing and number of procedures will depend on the properties of the drug used, the growth phase of the plant, and climatic conditions. Contact formulations create protection for ten to fifteen days (if there is no precipitation), systemic ones differ in a longer period lasting three weeks.
  • as soon as signs of the disease are detected, it should be performed extraordinary preventive treatment.

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.

What is the danger of tomato anthracnose and how to treat it?


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.


Large-fruited tomatoes for open ground

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.

The appearance of the stepsons

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.
