Fungicide "Abrusta" by "DuPont" company is considered a unique substance that provides reliable protection of cereal plants from various pathologies. The tool is considered an effective fungicidal preparation that has a complex effect on the roots and ground plant fragments. In addition, the substance helps to increase the activity of the photosynthesis process. In order for the use of the composition to give results, you must strictly follow the instructions.
Composition and form of release of funds
This Dupont product includes 2 active ingredients at once. 1 liter of the substance contains the following:
- 150 grams of pentiopyrad;

A suspension concentrate is considered a preparative form of the agent. The product belongs to the chemical class: pyrazole-carboxamide + triazole. It is sold in 5 liter canisters.
Principle of operation
There are 2 active substances in the fungicide. These include pentiopyrad, which is considered to be a compound of carboxamides, and cyproconazole, which is part of the triazole class. This combination provides a noticeable therapeutic and prophylactic fungicidal effect. The product helps to strengthen cereals during the intensive cultivation phase and ensures a good harvest with high quality grains. As a result, growing crops becomes more profitable.
According to the principle of action, Pentiopyrad has significant differences 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 thought to be fragments of the mitochondrial chain that is required to move electrons.
As a result, there is a violation of metabolic processes at the cell level. In this case, pathogens are faced with a sudden lack of energy. Pentiopyrad is considered a powerful prophylactic and therapeutic agent with a pronounced physiological effect on plants.

Cyproconazole inhibits the production of ergosterol and other fungal sterols. Unlike other drugs from the triazole group, cyproconazole has a wide range of effects.
This is due to its unique ability to quickly and easily be absorbed and move around the plant. At the same time, the tool does not lose its effectiveness even with temperature fluctuations. It is characterized by excellent healing properties and a long protection period.

For what purposes is it needed
Key indications for use of the substance include the following:
- powdery mildew;
- septoriasis of foliage and ears;
- brown and yellow rust;
- net spotting;
Consumption rate of funds
When using the substance, it is important to observe the dosage. It is shown in the table:
|Culture||Pathology||Application rate, liters per hectare||Deadline for entering|
|Winter wheat||Pyrenophorosis, septoria, rust, powdery mildew||0,7-1||Beginning stage of going into the tube, stage of ligula|
|Spring and winter barley||Net spot, ramulariosis, rust, rhynchosporia, powdery mildew||0,7-1||Growing season|
It is required to make 200-300 liters of working solution per hectare of planting. The waiting period before harvest must be at least 1 month. Fungicide "Abrusta" can be used 2 times.

Instructions for the use of the fungicide "Abrusta"
Treat barley and wheat with a fungicidal agent at the end of the tillering stage or at the beginning of stemming. This will help protect cultures from pathologies and provide them with 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, 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.
