Crop protection tank mixes: recipe table and how to cook

Tank mixtures for plant protection and nutrition are made up of compatible ingredients. All these chemicals are highly soluble in water and do not react with each other. It can be difficult to choose preparations for the preparation of a tank mixture on your own. It is necessary to take into account not only the compatibility of the main components, but also various additives, surfactants. It is advisable to use ready-made mixtures of various chemicals.

Purpose and benefits of tank mixes

In order to protect cereals, vegetables, berries and fruits, it is advisable to use ready-made solutions or, as they are called, tank mixtures consisting of several chemicals dissolved in water.Multicomponent preparations are characterized by high efficiency, allow timely response to various adverse factors (presence of weeds, slow growth of crops, development of fungal diseases, insect infestation). The composition may include insecticidal, various fungicidal, herbicidal preparations, as well as growth stimulants, top dressing.

Benefits:

  • expanding spectrum;
  • protection period increases;
  • allows you to combine activities to protect, feed and care for crops;
  • reduces pesticide load;
  • reduce the negative effects of multiple chemicals;
  • saves financial, labor resources;
  • reduces water consumption, fuel and lubricants;
  • reduces the dosage of each of the chemicals included in the composition;
  • reduces mechanical damage to field crops;
  • reduces the number of sprays.

Tank mixtures are used in trailed and self-propelled vehicle sprayers. Reducing the number of trips of agricultural equipment will lead to a decrease in mechanical damage to field crops, and will also help preserve the loose structure of the soil.

Types of tank mixes:

  • factory solutions;
  • self-made from several preparations.

It is important to remember that when several chemicals are used together, the dosage of each is reduced by 10-30 percent.

Multicomponent solutions can significantly reduce costs. It is recommended to choose the right preparations for formulating the mixture.

Not all chemicals can be mixed in the same solution. In addition, there is a certain order in which permitted components are added, that is, it is necessary to adhere to the correct sequence of mixing substances.

Features of compilation

Which chemicals can be used in tank blending:

  • with the same functions, but different way of action (contact + system);
  • for various purposes (insecticide + herbicide, growth regulator + fungicide);
  • fertilizers + pesticides for application with irrigation water;
  • dry fertilizers + pesticides;
  • liquid fertilizers + pesticides + growth regulators + microfertilizers;
  • solid fertilizers + liquid pesticides;
  • fungicides + microfertilizers + growth regulators (for seed treatment).

Factors to consider when formulating blends:

  • coincidence of terms of use of chemicals;
  • physical and chemical compatibility of the components used;
  • water characteristics;
  • correct sequence of mixing substances.

Rules for adding compatible chemicals:

  • Water-soluble polymer bags with pesticides are added at the very beginning;
  • powders, dispersion granules are added before oil preparations and liquid top dressings with a high s alt content;
  • oil-containing components are added with care, they lead to the "coagulation" of dissolved fertilizers;
  • in the presence of surfactants after oil-containing substances, water-soluble components can be added to the solution (surfactants envelop the oil, prevent flocculation);
  • at the very end add aqueous solutions and concentrates;
  • fertilizers are added after protection.

It is advisable not to experiment, but to buy ready-made factory multicomponent solutions.The physico-chemical properties of the chemicals included in the composition of self-prepared mixtures may change. As a result of such a change, the toxicity of the resulting solution in relation to the treated crops will increase. In addition, the precipitate that precipitates in the event of a reaction often disables the sprayer's atomizer.

Incorrectly formulated mixture may not immediately, but later, show its phytotoxicity to crops, for example, when the air temperature rises.

Compatibility rules

When self-composing tank mixtures, it is necessary to adhere to the rules of physical and chemical compatibility of various chemicals. The instructions for any drug provide information about the features of its use. Before formulating mixtures, it is necessary to study the recommendations of the manufacturers.

Rules for the preparation of tank mixes, taking into account compatibility rules:

  1. Prepare the solution on the day of spraying.
  2. Read instructions.
  3. Make sure the components are compatible.
  4. Do a compatibility test.
  5. Watch the reactions.
  6. Prepare stock solution.
  7. Reduce the dose of each chemical by 10-30 percent.
  8. Follow the rules for adding components.
  9. Connect mother liquors in the tank.

Before pouring chemicals into the tank, it is advisable to do a compatibility test. For testing, a three-liter glass jar is suitable. The drugs in the dosage indicated in the instructions are added, observing the order. A jar of chemicals and water is closed with a lid, shaken well and the result is evaluated immediately and after thirty minutes.

If no precipitate has formed, the solution has not become cloudy, has not exfoliated, has not become like a curd mass, has not heated up, does not emit gas, does not form foam, then the reaction is neutral, and chemicals are allowed to be used together.The mixture must be homogeneous, without flakes and solids in the composition, in which case it will not clog the spray tubes and will not cause crop burns.

What can not be mixed in a common tank?

Chemicals that must not be mixed in the same tank:

  • contact and systemic herbicides;
  • some crop protection products with fertilizers;
  • boron supplements and oil preparations;
  • calcium products and preparations with iron, zinc, magnesium, manganese;
  • feeding with calcium and top dressing with sulfur and phosphorus;
  • two kinds of multicomponent liquid fertilizers;
  • several different growth regulators.

How to properly spray plants

Factors to consider:

  • wind speed less than 4 meters per second;
  • air temperature +12… +24 degrees Celsius;
  • humidity - no more than 60 percent;
  • spraying is carried out in the morning, after the dew has dried, or in the evening;
  • process crops only in clear weather (but not in the heat);
  • probability of precipitation in the coming hours should be minimal;
  • water for the preparation of solutions is taken warm (+10 … +25 degrees), clean, soft, neutral or slightly acidic, without impurities, suspended particles.

Crop spraying regulations:

  1. The sprayer tank is filled 1/3 or 2/3 with water.
  2. Alternately, following the correct sequence, pour in the prepared stock solutions.
  3. All components are mixed.
  4. Water is added to full volume.
  5. Spray only he althy crops that have not been affected by frost or drought.
  6. Agitators must be constantly running while spraying.
  7. After the treatment, the remaining solution must be drained from the tank, and the container itself should be thoroughly rinsed.

Safety precautions

Mixing chemicals, preparing stock solutions, spraying fields is allowed only with the use of protective equipment. It is necessary to protect the respiratory organs (respirator), eyes (glasses), hands (rubber gloves), legs (rubber boots), body (special protective suit).

It is forbidden to inhale the vapors of the mixture, use chemicals. If the solution comes into contact with the skin, it is recommended to wash the contaminated area with clean water. In case of accidental use of chemicals, it is recommended to induce vomiting and seek medical attention.
