Fungicides are agrochemicals designed to prevent and treat various plant infections. There are a huge number of products on the market, some designed for vegetables, others for forage grasses and cereals, and still others for protecting fruit trees and shrubs. For example, the fungicide "Alpari" is designed for treating grain crops and sugar beets, and today's story explores its capabilities.
What is included in the composition and existing forms of release
This product is a two-component systemic fungicide. It is available as a concentrated emulsion. The presence of two components, both triazoles, enhances its effectiveness.
The active ingredients of Alpari are:
- propiconazole - 250 grams/liter;
- cyproconazole - 80 grams/liter.
This product is a contact and systemic pesticide with preventative and therapeutic effects. It is available in 5-liter plastic canisters.
Mechanism of action
The two components of this fungicide provide a comprehensive effect on the treated plants. The pesticide begins to work immediately after application to the infection site.
Propiconazole inhibits ergosterol biosynthesis, stops fungal spore formation, and stops the infection from spreading within two days of spraying. The substance stimulates plant development and growth, enhancing photosynthesis in the flag leaves of cereals.
Cyproconazole, transported within the stems and leaves of plants, targets various types of smut, inhibiting sterol biosynthesis, even at low concentrations. This complex action provides:
- protection of sugar beets from most fungal infections;
- preventive and therapeutic effects on cultivated crops;
- protecting plants from powdery mildew;
- effective action from the first hour after application;
- long-term protection of crops, up to 28 days;
- can be used throughout the growing season.
What is it used for?
Alpari is used for spraying sugar beet, spring and winter wheat, barley, winter rye, and oats. The fungicide prevents the development of various types of rust and spot, powdery mildew, and septoria.
Calculation of consumption
The drug is used according to the manufacturer's instructions; it is unacceptable to exceed the concentration of the fungicide when preparing the working solution.
| Fungicide consumption (concentrate), in liters per hectare | Plants to be processed | What infections does it protect against? | Consumption of working fluid, in liters per hectare, processing time |
| 0.5-0.7 | Sugar beet | Powdery mildew, phomosis, cercospora | 300. Growing season, 1 treatment upon detection of the disease, 2 – 2 weeks after the first spraying. |
| 0.4-0.5 | Winter and spring barley | Striped, net, dark brown spot, dwarf, stem rust, powdery mildew, rhynchosporiosis. | 300. Growing season |
| 0.4-0.5 | Winter and spring wheat | Brown, yellow, stem rust, powdery mildew, pyrenophorosis. | 300. Growing season |
| 0.4-0.5 | Winter rye | Stem and brown rust, rhynchosporiosis, powdery mildew, septoria | 300. Growing season |
| 0.4-0.5 | Oats | Red-brown spot, crown rust | 300. Growing season |
For cereals, one treatment is sufficient. Spraying should be done in cloudy, windless weather.
Instructions for use
Crops are treated with a working solution of the preparation. It is prepared before spraying and stored for no more than 24 hours. Preparatory work is carried out in a specially equipped area. One-third of the required volume of water is poured into a tank with the agitator running, the emulsion concentrate is added, and water is added to the calculated volume, constantly stirring. The prepared solution is poured into the sprayers.
Precautionary measures
Plant treatments are carried out wearing protective suits, respirators, and special gloves. Personnel undergo preliminary safety training for working with fungicides. Smoking and eating are prohibited during work. Alpari is classified as hazard class 3 (moderate toxicity) for humans and bees. It is not used in water protection zones.
How much and how to store
Agrochemicals are stored in dry, cool, well-ventilated areas. Warehouses are located separately from residential buildings; animal feed and additives for poultry are not stored nearby. Fungicides are kept in tightly sealed, factory-sealed packaging with legible information about the name, purpose, and composition of the product. The fungicide has a shelf life of two years.
Analogues
Preparations identical in active substance: "Alto Super" EC; "Atlant Super" EC; "Virtuoz" EC; "Maestro" EC; "Profi Super" EC.
