Fungal diseases cause significant damage to the crop. Farming is now impossible to imagine without fungicides. In Russia, the company "August" produces the fungicide Kolosal, which helps farmers to resist a wide range of diseases of cereals and industrial crops.
Composition of the preparation
The fungicide is produced in the form of a concentrated microemulsion that is sold in 5-liter canisters. A system of substances was specially selected for the preparation, with the help of which the particle size of the fungicide in the working fluid is less than 200 nanometers. This structure enables the drug to be more fully incorporated into plant tissues. This fact explains its high protective activity.
Systemic fungicide Kolosal Pro consists of two components: propiconazole and tebuconazole, combined in a ratio of 300 g / l: 200 g / l. The chemicals belong to the same class, inhibit different groups of fungi at the cell level, and combine to provide an effective drug. Fungicide Kolosal Pro protects cereals, peas, soybeans, rapeseed, sugar beets and grapes from common diseases.
Propiconazole and tebuconazole are harmful to pathogens. Propiconazole simultaneously inhibits the formation of spores and is a growth regulator for cereals, which contributes to their rapid recovery after infection. The substance acts on pathogens that cause powdery mildew. The action of tebuconazole is directed against fungi, pathogens of fusarium, alternaria, and rust.
Mechanism of action
The active substances of Kolosal Pro are absorbed by the plant at the cellular level and pass up the stem and leaves. The whole plant becomes protected from fungi in 2-4 hours after the working solution hits the surface. The high rate of penetration of the fungicide into the tissue of crops and the uniform distribution of active active ingredients throughout the plant creates a strong barrier against fungi.
Both fungicides in the composition of Kolosal Pro also show a prophylactic effect over a long period. Treated plants are protected for 25-35 days. Germinating introduced spores will be destroyed by active chemicals.
Spectrum of influence
In accordance with the instructions for the fungicide Kolosal, the drug must be used against certain fungal infections on plants.
- The tool is able to resist such diseases of cereals: brown, stem, dwarf, yellow rust, dark brown, reticulate, striped spots, rhinhosporium, pyrenophorosis, septoria;
- Fights against infection of sugar beet with powdery mildew, phomosis, cercosporosis;
- Protects rapeseed from phomosis, powdery mildew, Alternaria;
- Suppresses pathogens spreading to soybeans: alternariosis, anthracnose, ascochitosis, septoria, cercospora;
- Destroys the causative agents of pea diseases: rust, anthracnose, ascochitosis, powdery mildew;
- Protects grapes from powdery mildew.
Benefits
An effective drug is chosen by agronomists of many farms, positively assessing its antifungal effect.
- The combination of two potent substances makes it possible to use the fungicide Kolosal Pro on many crops against a wide range of fungal diseases;
- The improved structure of the fungicide provides a high penetrating ability of the drug into plant tissues;
- Due to its fast penetration into green fabrics, the product is resistant to rain;
- When using Kolosal Pro, the expected result is guaranteed in a short period of 2-3 days;
- The drug of systemic action effectively destroys the mycelium. The best indicators are obtained at the initial stages of culture infection;
- Plants are protected for a long period;
- Prevention and treatment are complemented by growth stimulation;
- The drug is economically beneficial: a little effective substance is consumed on the most important crops.
How to achieve maximum effect
The instructions for use of the fungicide Kolosal Pro emphasize that the best results are obtained in the early stages of a crop disease. The disease is just beginning to develop, the plants have suffered little, and the fungicide will cope with the nascent colonies of fungi and improve the crops.
- The fields with cereals are sprayed in the growing stage, when the first symptoms of the disease are noticed;
- Sugar beet begins to be processed when the mycelium has spread. The second treatment, if necessary, is carried out after one and a half or two weeks;
- The development of spring rape is monitored especially closely in the phase of growing stems and the formation of pods of the lower layer, so as not to miss the possible onset of infection;
- Winter rape is processed twice. The first spraying is carried out as a preventive measure in the fall, when 6-8 leaves will develop on the plants. The second time processing may be forced if in the spring during the creation of pods in the lower tier a disease appears;
- Kolosal Pro is used for soybeans and peas during the growth period;
- Fungicide will help grapes to improve their health before or after flowering, while forming small ovaries or berries the size of a pea.
Multiplicity of treatments
Given the effectiveness of the potent fungicide Kolosal Pro, the instruction regulates the number of maximum treatments for different crops.
- A single spraying is carried out on spring and winter wheat, barley, other grain crops and on spring rape;
- Once or twice, depending on the need, apply the fungicide on crops of winter rape, peas, soybeans, sugar beets;
- The grapes are allowed to be processed three to four times at the agreed stages of its development.
Waiting period
It is necessary to spray crops, calculating the timing of their ripening.
- All cereals can be processed at least 38 days before harvest;
- The waiting period for grapes and sugar beets is 30 days;
- Peas and rapeseed can be harvested 40 days after processing.
Application
To work with the drug, no stock solution is prepared. The instructions for use of the fungicide Kolosal emphasize that the working solution is prepared immediately before spraying. The tank is filled with water in half and the entire volume of the drug required for operation is poured. Add water while stirring. Stir the working solution during spraying to maintain uniformity. Use the entire volume of the prepared chemical. The solution cannot be stored.
Kolosal Pro can be mixed with all herbicides and insecticides produced by August. Composing tank mixtures, Kolosal fungicide is added to the tank last. Before using the mixture, you need to check it for compatibility, and also make sure that it is not phytotoxic to the culture that is going to be processed.
Consumption rates
For a hectare of grain crops, only 300 liters of the working solution of the Kolosal Pro preparation are required. The instruction specifies that the processing of peas and soybeans requires 200 - 400 liters per hectare. The consumption of the working solution on grapes increases to 800 - 1000 l / ha.
The drug is effective against fungi, but it must be carefully applied in relation to the environment.
