Fungal diseases cause significant damage to crops. They reduce yields, spoil the quality of fruits, and sometimes completely destroy crops. Modern agricultural technology involves the use of antifungal drugs to protect and cure plants. Kolosal Pro is a two-component systemic fungicide used by professionals in highly productive agricultural production.

Composition, release form and purpose of the drug Kolosal Pro
The product for combating fungal infections includes 2 active ingredients:
- propiconazole – 300 grams per liter, that is, 30%;
- tebuconazole – 200 grams per liter, 20%.
These substances belong to the group of triazoles - organic compounds that inhibit the synthesis of sterols in the body of fungi.
High fungicidal properties are ensured by the fine dispersion of the solution - Kolosal particles do not exceed 200 nanometers.
The fungicide is produced in plastic canisters of 5 and 10 liters. The developer and manufacturer of the drug is Avgust LLC, Russia.
Kolosal was created for the industrial treatment of agricultural crops over large areas against fungal infection. Areas of application:
- Cereals. Rust – brown, yellow, stem, dwarf. Spotting – dark brown, netted, striped. Powdery mildew.
- Grapes are oidium.
- Sugar beet – fomoz, cercospora, powdery mildew.
- Soybean – ascochyta blight, cercospora blight, alternaria blight, septoria blight, anthracnose.
- Rapeseed - phomosis, powdery mildew, alternaria.
- Peas - anthracnose, rust, powdery mildew, ascochyta blight.
The drug is defined as a nanoemulsion; the smallest particles are easily sprayed and distributed throughout the tissue structures of plants in a short time.
Mechanism of action of the fungicide
The components of Kolosal Pro, which are in a state of fine suspension, rise up through the plant conduction system and are distributed throughout all tissues. Both active substances suppress and stop the synthesis of ergosterol in the membranes of fungal cells. The death of fungi leads to a stop in the growth of mycelium (mycelium as a whole).
Tebuconazole and propiconazole have different areas of activity. The combined action suppresses all types of pathogenic flora. For infected crops, Kolosal Pro serves as a medicine, freeing it from pathogenic flora that have penetrated inside.
Propiconazole also stimulates vegetation in crops, as it increases the rate of photosynthesis.
Period of protective action and speed of exposure
2-4 hours after spraying, Kolosal spreads throughout tissue structures and begins to work. It stops the growth of mycelium, kills fungi that have penetrated inside and are destroying the plant.
Activity against pathogenic flora persists for 4-5 weeks. Precipitation does not affect the effectiveness of Kolosal. As the temperature rises, the fungicidal properties increase.
Positive and negative sides
The undoubted advantages of the drug include:
- activity against most known fungi;
- high penetrating ability into all plant tissues;
- speed of action and long-term activity of the drug;
- pronounced medicinal properties - eliminates fungi from completely affected crops;
- used in any weather conditions, the effect covers almost the entire growing season;
- does not have an inhibitory effect on soil microorganisms.
The negative aspects of the impact and use of Kolosal Pro are considered:
- does not stop the formation of spores in some types of fungi, which requires repeated treatments;
- the drug is difficult to neutralize, therefore it is not used in homestead conditions;
- highly toxic to bees, beneficial insects, fish;
- It does not eliminate some types of fungal infections, in particular fusarium and root rot.
The drug is not used to protect seedlings and seedlings.Cereals should be pollinated before they emerge into the tube, since it does not penetrate into the ears later.
Consumption rate for different plants
The manufacturer suggests using Kolosal in the following quantities:
Culture | Liters of product per hectare | Working fluid volume (liters) | Waiting time (days) |
Cereals | 0.3-0.4 | 300 | 38 |
Grape | 0.2-0.3 | 800-1000 | 30 |
Rape | 0.5-0.6 | 200-400 | 40 |
Legumes | 0.4-0.6 | 200-400 | 40 |
Sugar beet | 0.4-0.6 | 200-400 | 30 |
The upper permissible value of the amount of fungicide is chosen if the crops are heavily infected.
How to prepare a working solution
The mother liquor is not diluted separately. The required volume of the drug is poured into a container half filled with water and stirred. Add the remaining water. Stirring is also carried out during spraying.
The remaining solution is disposed of and cannot be stored.
Application procedure
According to the instructions, the earlier the crops are treated, the more effective the fungicide is applied - at the beginning of the spread of the fungus and on young growing crops. Rules of application:
- grains – 1 time during early growing season;
- grapes - 3-4 times, the first time - before flowering, the last time - when the grapes are the size of peas;
- sugar beets, legumes, rapeseed - 1-2 times.
Crops are treated before the fungi damage the internal structures of the plants, in order to prevent crop loss.
Safety rules for use
When working with fungicide, you must follow the prescribed safety rules:
- Pour into containers on special platforms (concrete, compacted earth). Distance from housing, premises for animals, pastures, water sources - 200-500 meters.
- When diluting the fungicide and spraying, use protective suits - overalls, boots, respirators, goggles, gloves.
- Upon completion of work, wash thoroughly.
- Remains of the fungicide solution are disposed of using special means.
Store canisters in isolated storage rooms, separate from things, equipment, and products.
Information: there is no antidote for Kolosal; in case of poisoning, the usual means are used - gastric lavage, taking adsorbents.
Possibility of resistance
The drug is a systemic fungicide; the development of resistance in pathogenic flora, when used correctly, is not observed.
Degree of toxicity of the fungicide
Kolosal Pro is classified as a highly dangerous class 2 drug.
Is it compatible with other products?
All crop protection products from August are compatible and can be used together. Pesticides and herbicides are mixed in a container with water, and Kolosal is added last.
The fungicide is not combined with concentrated alkalis or acids. After preparing the solution, a control test for phytotoxicity is required before treatment.
Storage of the drug
The fungicide, located in closed factory packaging, is stored in special premises for no more than 2 years. Permissible temperature range – from -15° to +35°.
Similar means
To protect and treat different types of crops, fungicides with one or more active ingredients are used:
- PropiChance Universal. Complete analogue containing active components in the same proportions. Manufacturer: Agro-Alliance.
- Altazol. Manufacturer: Technoexport. Contains 2 active ingredients – propiconazole and cyproconazole. Used for grains, sugar beets.
- Forecast. Systemic fungicide with propiconazole as an active ingredient.
- Soligor. Used for grain crops. Contains 3 active ingredients. Systemic fungicide.
If the type of pathogen is determined, fields can be treated with a smaller-spectrum fungicide with one active component.
The use of Kolosal Pro is a reliable and proven way to protect plants and obtain a stable harvest. Knowing the rules and strictly following the instructions for using a fungicide reduces the risk of toxic effects on the land, crops and humans.
