The fungicide "Kolosal" is a systemic product with therapeutic and preventative properties. It helps combat a wide range of fungal diseases. It is commonly used on rapeseed, grapes, rice, and cereal crops. For the product to be effective, it must be applied correctly. To ensure this, it is recommended to strictly follow the instructions.
Composition, existing forms of release and purpose
"Kolosal" is a systemic medication that consists of two components. One liter of the product contains the following ingredients:
- 300 grams of propiconazole;
- 200 grams of tebuconazole.
The substance is produced as an emulsifiable concentrate. It is used to combat various types of rust, powdery mildew, and fusarium. It also helps combat Alternaria, powdery mildew, and leaf spot.
How does the product work?
The active ingredients of the drug inhibit the production of ergosterol in the cell membranes of plant pathogens. As a result, the cell walls of harmful microorganisms are destroyed, and mycelial growth is stopped. The active components migrate acropetally and are quickly absorbed by the vegetative parts of crops. Tebuconazole has preventive properties and a therapeutic and systemic effect. It effectively eliminates powdery mildew and rust.
Propiconazole has both preventative and therapeutic properties. It helps suppress spore formation in pathogens and combat various types of spotting. It also promotes growth, improves carbon dioxide uptake by crops, and enhances photosynthesis.
How long does the effect last and how quickly does it work?
This fungicide penetrates the plant's structure through the leaves and stems. This occurs within 2-4 hours after application. The substance is evenly distributed throughout the plant tissues, preventing the spread of pathogens.
Pros and cons
The product has virtually no drawbacks. The only drawback is the need to strictly follow the instructions and safety rules.
Calculation of consumption
The application rate of the working solution depends on the crops to be treated. For grain crops, 300 liters per hectare is required. For rice, 200-300 liters of liquid per hectare are used.
Rules for preparing the working mixture
