Grain dressing helps to protect future crops from diseases and pests. Fungicides are considered the best in terms of fighting fungi. Modern drugs are low-toxic and do not pose a particular danger to humans and the environment. One of the effective remedies is Triaktiv fungicide, which consists of three active ingredients.
Composition
Triaktiv is the newest means of fighting fungal diseases of grain crops. The drug consists of three active ingredients:
- azoxystrobin - 100 g / l;
- cyproconazole - 40 g / l;
- tebuconazole - 120 g / l.
Each constituent substance is an active fungicide.
Act
Considering the instructions for use about Triactive fungicide, it is worth paying attention to the action of each active substance:
- Azoxystrobin is a means of contact as well as translaminar action. The active ingredient protects and heals crops from fungus. The fungicide inhibits the growth of mycelium and the awakening of spores. The active ingredient has a systemic effect. After spraying crops, the fungicide can be redirected to neighboring plants in contact with foliage.
- Tebuconazole and cyproconazole have a similar systemic effect. Immediately after spraying, the substances are absorbed and distributed throughout the plant. The components destroy the cells of the fungus, prevent them from developing, which leads to the complete destruction of the fungal organism.
Thanks to the successful combination of three components, Triaktiv cures a whole range of diseases of grain crops, and also has protective preventive actions.
Positive qualities of the fungicide
The usefulness of Triaktiv is confirmed by five advantages:
- A successful combination of three active ingredients with different actions.
- Triactive effectively protects and heals foliage, stems, ears from fungal diseases.
- The fungicide has a long duration of action. Active protection prevents re-infestation of crops, preserves the integrity of the foliage.
- Thanks to azoxystrobin, grain crops develop resistance to stressful conditions.
- Triaktiv ensures a grain harvest even in bad weather conditions.
The disadvantages of the fungicide have not yet been identified.
The Importance of Chemical Grain Etching
Chemical dressing of grain allows for integrated protection. It is not only the seed that is affected. Protection extends to shoots, root system, leaves, stems and mature ears. Harmful microorganisms are destroyed by the fungicide at different stages of development.
The causative agents of fungal diseases are not only found on grains or growing crops. Microorganisms take root well in the soil, hibernate, and in spring they wake up and begin to spread over fresh crops. Winter and spring flies, aphids, carrying the causative agents of the disease of yellow dwarfism in barley, are of great danger.
A systemic fungicide used for seed dressing protects crops early from windborne fungus.Farmers do not need early spraying of plantings from powdery mildew.
Methods for chemical etching of grain
Chemical dressing of grain is carried out using machines or special devices. For each treatment method, use its own form of the drug. There are four main methods of dressing grain:
- The simplest method of dressing grain is dry processing. The process takes place in a specialized machine. The disadvantage of this method is the uneven coating of all grains with a chemical preparation. The active substance is poorly retained on the shell of dry seed. During the pickling process, a lot of dust is generated.
- The semi-dry method of dressing provides for light moistening of the grain. No more than 10 liters of water is sprayed on 1 ton of dry seeds. From such an amount of liquid, the moisture content of the grain remains unchanged, which eliminates the need for additional drying. The processing process takes place in a specialized machine. The chemical is dissolved in water, which is sprayed on the grains.
- The wet method of dressing is based on a strong moistening of the grain. Seed material is sprayed, watered or completely soaked in water with a dissolved chemical. At the end of the pickling process, the grains are subjected to additional drying to the optimum moisture content.
- Good performance is obtained by treating grain before sowing with a fungicide and a polymer substance. The process is called hydrophobization. After processing, a thin but very strong film is formed on the surface of the grain. The fungicide is firmly adhered to the seed coat under the polymer. The method allows to ensure good activity of the fungicide, increases the germination process and yield. Grains after hydrophobization are easier to tolerate low soil temperatures
Of all the methods of dressing, hydrophobization makes it possible to more effectively protect grain from diseases and negative natural factors.
The process of dressing grain with a fungicide
All cereals, especially winter crops, require dressing before planting. Farmers who want to save money are trying to limit themselves only to autumn fungicide treatment. Unjustified savings lead to a large loss of yield. Expenses increase, since the invested funds do not bring profit.
Conventionally, the entire etching process can be divided into five steps:
- Grain material is sent for phyto-examination. The causative agents of diseases are determined in the laboratory. Based on the data obtained, a chemical preparation is selected.
- Before dressing, the grain material undergoes a preparation stage. Seed of the middle fraction is selected. Impurities of dust, weed grains, as well as damaged seeds are sifted out. Etching without a selection process is irrational. About 20% of the fungicide is used for other purposes, since the drug is consumed on unnecessary impurities.
- According to the result of the examination, a dressing agent is selected that belongs to the desired chemical group. Additionally, not only the name of the drug is taken into account. It is important to choose the right fungicide according to the mechanism of action. Contact drugs form a protective shell around the grain, but do not penetrate into the tissues themselves. Systemic fungicides act from the inside, penetrating the seed and also disinfect the soil around the grain. Complex preparations perform the functions of contact and systemic fungicides. As an example, we can take the disease of head smut, where only drugs of systemic action are able to cope. And a simple contact fungicide will save you from hard smut. Means containing triazole are effective against root rot and the appearance of mold on seed material.Considering that a grain crop can be infected with any disease, Triaktiv is considered effective for processing.
- The fourth step can be called the most important. At this stage, the fungicide formulation is selected. The quality of the dressing depends on the intensity of adhesion of the agent to the seed coat. Powdered fungicides, even when wetted, do not adhere well to the seed. It is better to use concentrated suspensions. And in this regard, Triaktiv wins.
- The last steps are related to setting up the machine. The mechanisms are adjusted so that the seed is fed evenly and treated with the working solution. Achieve uniform mixing of the grain during pickling. The working solution supply is adjusted so that the deviation from the norm does not exceed 5%. In this case, the completeness of seed dressing should be more than 80%.
Violation of the seed dressing technology threatens with a loss of yield in the range of 20–80%. The approximate consumption of the fungicide Triaktiv per 1 ton of winter wheat is 0.2–0.3 liters.
When processing crops, the drug has shown itself to be an effective fungicide that protects crops from powdery mildew, fusarium and black ears, rust, and other types of diseases. Consumption of concentrated Triaktiv for spraying an area of 1 hectare is from 0.6 to 1 liter.

The broad-spectrum preparation Triaktiv provides comprehensive protection of grain crops from diseases. For a farmer, this is a triple success in work, cost savings and a stable harvest.
