Fungal diseases cause significant damage to the crop. It is now impossible to imagine farming without fungicides. In Russia, the August company produces Kolosal fungicide, which helps farmers resist a wide range of diseases of cereals and industrial crops.
Composition of the drug
The fungicide is produced in the form of a concentrated microemulsion, which is sold in 5-liter canisters. A system of substances was specially selected for the drug, with the help of which the particle size of the fungicide in the working fluid is less than 200 nanometers. This structure allows the drug to penetrate more completely into plant tissue. This fact explains its high protective activity.
Systemic fungicide Kolosal Pro consists of two components: propiconazole and tebuconazole, combined in a proportion of 300 g/l:200 g/l. The chemicals belong to the same class, suppress different groups of fungi at the cellular level and, when combined, represent an effective drug. Fungicide Kolosal Pro protects grain plants, peas, soybeans, rapeseed, sugar beets and grapes from common diseases.
Propiconazole and tebuconazole have a detrimental effect on 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 affects 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 the drug Kolosal Pro are absorbed by the plant at the cellular level and pass up the stem and leaves. The entire plant becomes protected from fungi 2-4 hours after the working solution hits the surface. The high speed of penetration of the fungicide into crop tissue and the uniform distribution of active ingredients throughout the plant creates a strong barrier for fungi.
Both fungicides in Kolosal Pro also exhibit a preventive 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 should be used against certain fungal infections on plants.
- The product is able to resist the following diseases of grains: brown, stem, dwarf, yellow rust, dark brown, net, striped spot, rhynchosporium, pyrenophorosis, septoria;
- Fights infection of sugar beets with powdery mildew, phomosis, cercospora;
- Protects rapeseed from fomoz, powdery mildew, alternaria;
- Suppresses pathogens spreading on soybean: Alternaria blight, anthracnose, ascochyta blight, septoria blight, cercospora blight;
- Destroys pathogens of pea diseases: rust, anthracnose, ascochyta blight, powdery mildew;
- Protects grapes from oidium.
Advantages
The 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 Kolosal Pro fungicide on many crops against a wide range of fungal diseases;
- The improved structure of the fungicide ensures high penetration of the drug into plant tissue;
- Thanks to its rapid penetration into green fabrics, the product is resistant to rain;
- When using Kolosal Pro, the expected result is guaranteed in a short period, measured in 2-3 days;
- The systemic drug effectively destroys mycelium. The best results 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 small amount of the effective substance is consumed on the most important agricultural crops.
How to achieve maximum effect
The instructions for using the Kolosal Pro fungicide emphasize that the best results are obtained in the early stages of crop disease. The disease is just beginning to develop, the plants have suffered little damage, and the fungicide will cope with the nascent colonies of fungi and improve the health of the crops.
- Fields with cereals are sprayed at the growth stage, when the first symptoms of the disease are noticed;
- They begin to process sugar beets after noticing the spread of mycelium. The second treatment, if necessary, is carried out after one and a half or two weeks;
- The development of spring rapeseed is monitored especially carefully in the phase of growing stems and the formation of lower tier pods, so as not to miss the possible onset of infection;
- Winter rapeseed is processed twice. The first spraying is carried out for preventive purposes in the fall, when the plants develop 6-8 leaves. The second time, treatment may be forced if in the spring, during the creation of pods, a disease appears in the lower tier;
- Kolosal Pro is used for soybeans and peas during the growth period;
- The fungicide will help improve the health of grapes before or after flowering, when small ovaries or berries the size of a pea are formed.
Frequency of treatments
Considering the effectiveness of the potent fungicide Kolosal Pro, the instructions regulate the number of maximum treatments for different crops.
- A single spraying is carried out on spring and winter wheat, barley, other grain crops and spring rape;
- Once or twice, depending on the need, apply the fungicide to the crops of winter rapeseed, peas, soybeans, and sugar beets;
- Grapes are allowed to be processed three to four times at specified stages of their development.
Waiting period
It is necessary to spray crops, calculating the timing of their ripening.
- All grains 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 treatment.
Application
To work with the drug, do not prepare a stock solution. The instructions for use of the Kolosal fungicide emphasize that the working solution is prepared immediately before spraying. The tank is filled halfway with water and the entire volume of the drug required for work is poured in. While stirring, add water. The working solution must be stirred during spraying to maintain uniformity. Use the entire volume of the prepared chemical. The solution cannot be stored.
The drug Kolosal Pro can be mixed with all herbicides and insecticides produced by the August company. When 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 crop that is going to be processed.
Consumption rates
For a hectare of grain crops, only 300 liters of working solution of Kolosal Pro is required. The instructions specify that when processing peas and soybeans, 200 - 400 liters per hectare are required. The consumption of the working solution on grapes increases to 800 - 1000 l/ha.
The drug is effective against fungi, but it must be used carefully in relation to the environment.
