DuPont's "Abrusta" fungicide is considered a unique substance that provides reliable protection of cereal plants from various pathologies. The product is considered an effective fungicidal drug that has a complex effect on the roots and above-ground fragments of plants. In addition, the substance helps increase the activity of the photosynthesis process. In order for the use of the composition to produce results, you must strictly follow the instructions.
Composition and release form of the product
This Dupont product includes 2 active components at once. 1 liter of substance contains the following:
- 150 grams of penthiopyrad;
- 60 grams of cyproconazole.
The preparative form of the product is considered to be a suspension concentrate. The product belongs to the chemical class: pyrazole-carboxamide + triazole. It is sold in 5 liter canisters.
Principle of operation
The fungicide contains 2 active substances. These include penthiopyrad, which is considered a carboxamide compound, and cyproconazole, which is part of the triazole class. This combination provides a noticeable therapeutic and preventive fungicidal effect. The product helps strengthen cereal plants at the stage of intensive cultivation and ensures a good harvest with high-quality grains. As a result, growing crops becomes more profitable.
Penthiopyrad's principle of action differs significantly from many fungicidal substances. This component of the drug provokes the suppression of succinate dehydrogenase, which is a special enzyme, and complex II. They are considered fragments of the mitochondrial chain, which is required to move electrons.
As a result, there is a disruption of metabolic processes at the cellular level. At the same time, pathogens are faced with a sudden lack of energy. Penthiopyrad is considered a powerful preventive and therapeutic substance, which has a clear physiological effect on plants.
This is due to its unique ability to quickly and easily be absorbed and move throughout the plant.At the same time, the product does not lose its effectiveness even with temperature fluctuations. It is characterized by excellent healing characteristics and a long period of protection.
For what purposes is it needed?
Key indications for use of the substance include the following:
- pyrenophorosis;
- powdery mildew;
- septoria leaf and ear blight;
- brown and yellow rust;
- net spot;
- rhynchosporiasis;
- ramulariasis.
Consumption rate
When using the substance, it is important to follow the dosage. It is shown in the table:
Culture | Pathologies | Application rate, liters per hectare | Payment deadline |
Winter wheat | Pyrenophorosis, septoria, rust, powdery mildew | 0,7-1 | The stage of the beginning of egress into the tube, the ligula stage |
Spring and winter barley | Net spot, ramularia, rust, rhynchosporium, powdery mildew | 0,7-1 | Growing season |
It is necessary to apply 200-300 liters of working solution per hectare of plantings. The waiting period before harvesting should be at least 1 month. Fungicide "Abrusta" can be used 2 times. When using the substance to treat barley in the south, it is recommended to spray the crops regularly. This should be done in the T1 phase.
Instructions for use of the fungicide "Abrusta"
Barley and wheat should be treated with a fungicidal substance at the end of the tillering stage or at the beginning of booting. This will help protect crops from pathologies and ensure their resistance to adverse external factors.
The substance provides biological and physiological protection. At first, “Abrusta” helps to maximize the potential of the plant, protects it from diseases, improves root development, and increases resistance to lodging and drought.
Precautions for use
To avoid the negative effects of the fungicide on the body, it should be used very carefully. It is important to use personal protective equipment.
Terms and conditions of storage
The substance can be stored for 2 years. This can be done at temperatures from 0 to +35 degrees.
Analogs
Analogues of the substance include:
- "Tyler";
- Flint Star;
- "Madison."
The fungicide "Abrusta" is highly effective and successfully copes with fungi. For the use of the substance to be successful, it is important to strictly follow the instructions and observe safety precautions.
