Application of fungicide for tomatoes in a greenhouse and open field

These drugs are great helpto fight with bacterial diseases and fungi .They are constantly being improved by plant protection specialists, who develop new products, 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. To do this, it is recommended to know the types of drugs and features of their use.

Fungicidal preparations according to their origin and composition are divided into:

  • chemical inorganic ( with the content of copper, sulfur, iron compounds, salts and other elements);
  • chemical organic ( phthalimides, carbamates, morpholins, triazoles, strobilurins);
  • biological compounds for plants( from a fungus, from bacteria, from plants).
Treatment of tomatoes with a fungicide during the growing season

There are own groups of preparations for the application objects:

  • for seed and seed treatment;
  • antiseptic formulations and antibiotics for substrates;
  • for treating perennials in a dormant period;
  • formulations in the growing season.

By purpose :

  • prophylactic agents;
  • immunizing;
  • is of a medical type, which is excellent for the first three days in case of illness.

All fungicidal agents are distributed on the principle of impact :

  • contact - they cover all the bushes, acting as a kind of barrier;
  • system - through the covers enter the conductive systems of cultures, circulate inside with the juices.
Fungicidal in their appearance and level of exposure are simple and combined. The second group is able to work together with other fungicidal agents, insecticides, fertilizers, retardants.
Protective preparations can directly affect individual elements of tomato

These protective preparations affect pathogenic elements in several ways:

  • destroy the respiratory centers;
  • sterilize microorganisms, block nuclear fission;
  • stimulates cultures to produce antibiotics and phytoalexins;
  • creates necrotic barriers that protect unaffected plant tissue;
  • neutralize toxins of bacteria and fungi;
  • destabilizes cell membranes, inhibiting the production of ergosterol;
  • interrupt the synthesis of acidic compounds of the nucleic group;
  • upset energy metabolism.

How to properly apply

Peculiarities of treating vegetative crops:

  • protects and strengthens seedlings, if you use chemical compositions of the biological or immunizing group for contact and systemic effects;
  • terms and number of procedures will depend on the properties of the preparation used, the growth phase of the plant, climatic conditions. Contact formulations create protection for ten to fifteen days( if there is no precipitation), systemic differ by a longer period lasting three weeks.
  • As soon as symptoms of a disease are detected, should be performed with an extraordinary prophylactic treatment of .
To avoid the formation of resistance to systemic compounds, it is recommended to alternate the preparations.
