Table of recipes for tank mixtures for plant protection and how to do it correctly

Tank mixtures for protecting and feeding plants consist of compatible components. All these chemicals dissolve well in water and do not react with each other. It can be difficult to independently select preparations for preparing a tank mixture. It is necessary to take into account not only the compatibility of the main components, but also of various additives and surfactants. It is advisable to use ready-made mixtures of various chemicals.


Purpose and advantages of tank mixtures

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 and allow timely response to various unfavorable factors (the presence of weeds, slow crop growth, the development of fungal diseases, insect damage). The composition may include insecticidal, various fungicidal, herbicidal preparations, as well as growth stimulants and fertilizing agents.

Advantages:

  • the spectrum of action expands;
  • the protective period increases;
  • allows you to combine measures for protecting, fertilizing and caring for crops;
  • reduces pesticide load;
  • negative consequences from the use of several chemicals are reduced;
  • saves financial and labor resources;
  • reduces water and fuel consumption;
  • 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 visits of agricultural machinery will entail a reduction in mechanical damage to field crops, and will also help maintain the loose structure of the soil.

Types of tank mixtures:

  • factory solutions;
  • independently prepared from several drugs.

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 select the correct preparations for the mixture.

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

Features of compilation

What chemicals can be used when preparing tank mixtures:

  • with the same functions, but different modes of operation (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 mixtures:

  • 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:

  • at the very beginning, water-soluble polymer sachets with pesticides are added;
  • powders and dispersion granules are added before oil preparations and liquid fertilizers with a high salt content;
  • oil-containing components are added with caution, they lead to “curdling” 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 and prevent flocculation);
  • at the very end, add aqueous solutions and concentrates;
  • Fertilizers are added after protection products.

It is advisable not to experiment, but to buy ready-made factory multicomponent solutions. The physicochemical properties of the chemicals included in self-prepared mixtures may change.As a result of this change, the toxicity of the resulting solution towards the treated crops will increase. In addition, the sediment that falls in the event of a reaction often damages the sprayer nozzle.

Expert:
An incorrectly composed mixture may not immediately, but later, manifest its phytotoxicity to crops, for example, when the air temperature rises.

Compatibility Rules

When preparing tank mixtures yourself, you must adhere to the rules of physical and chemical compatibility of various chemicals. The instructions for any drug provide information about the specifics of its use. Before preparing mixtures, it is necessary to study the manufacturers' recommendations.

Rules for preparing tank mixtures taking into account compatibility rules:

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

Before pouring chemicals into the tank, it is advisable to do a compatibility test. A three-liter glass jar is suitable for testing. Drugs are added in the dosage indicated in the instructions, observing the order. Close the jar with chemicals and water with a lid, shake well and evaluate the result immediately and after thirty minutes.

If a precipitate does not form, the solution does not become cloudy, does not separate, does not become like a curdled mass, does not heat up, does not emit gas, does not form foam, then the reaction is neutral, and the chemicals can be used together.The mixture must be homogeneous, without flakes and solids in the composition, in which case it will not clog the sprayer tubes and will not cause crop burns.

What cannot be mixed in a common tank?

Chemicals that should not be mixed in the same tank:

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

Recipes for tank mixtures for plant protection

Popular recipes for preparing mixtures for different crops (table):

Name of crops Mixture components Action Yield increase percentage
Potato Fungicide + fertilizer “Aquarin” (3 kg per 1 ha) The risk of late blight is reduced, the volume of green mass increases By 15-20%
Tomato “Lignohumate” (0.05 percent solution) + pesticides Vigorous growth, powerful root system, long-lasting fruiting By 10-20%
Cabbage Humic fertilizers (0.04 percent solution) + pesticides Large leaves, drought tolerant By 10-15%
Grape “Acrobat” + “Collis” + “Fastak” or

"Ridomil" + "Tiovit Jet" + "Karate"

Protection against mildew, oidium, leafhopper larvae, thrips On 10 %

How to spray plants correctly

Factors that are recommended to pay attention to:

  • wind speed is 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;
  • cultivate crops only in clear weather (not in the heat);
  • the probability of precipitation in the coming hours should be minimal;
  • The water for preparing solutions is warm (+10...+25 degrees), clean, soft, neutral or slightly acidic, without impurities or suspended particles.

Rules for spraying crops:

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

Security measures

Mixing chemicals, preparing stock solutions, and spraying fields is permitted only with the use of protective equipment. It is necessary to protect the respiratory system (respirator), eyes (goggles), hands (rubber gloves), feet (rubber boots), body (special protective suit).

It is prohibited to inhale the vapors of the mixture or use chemicals. If the solution gets on the skin, it is recommended to rinse the area of ​​contamination with clean water. If you accidentally ingest chemicals, it is recommended to induce vomiting and seek medical attention.
