When choosing agrochemicals for plant protection, it can be difficult to find a universal option suitable for a variety of crops. Copper-based products are used to prevent fungal infections. A description of the properties of the fungicide "Kumir," designed to protect vegetable beds, fruit trees, and grapes, helps gardeners and farmers make the right choice.
Composition and existing forms of release
The product is used on various crops for preventative plant treatment against a number of fungal diseases. It is available as a suspension concentrate. The active ingredient in the fungicide is tribasic copper sulfate. Its concentration in the product is 345 grams per liter.
It belongs to the chemical class of inorganic substances + copper compounds. It is a protective pesticide. It penetrates through contact. Manufactured by August JSC, it is supplied to the market in 10-liter polymer canisters.
Operating principle and purpose
The product is used to treat vegetable crops (potatoes, tomatoes), fruit trees (pears, apples), and grapes. Copper-based preparations protect crops from a range of fungal infections, inhibit mycelial growth, enhance metabolic processes during the growing season, and increase chlorophyll production. The advantages of "Kumira" include:
- drug effectiveness;
- convenient dosage form;
- used in a plant protection complex, complements systemic fungicides;
- does not cause addiction and does not reduce the effectiveness of the effect.
The preparation provides plants with a protective effect, preventing the germination of fungi and their spread in crop tissues.
Important: maximum effect is achieved with preventative treatment of plantings before the appearance of a fungal infection.
The product is used to protect plants from:
- late blight;
- Alternaria;
- scabies;
- moniliosis;
- mildew.
The product is not phytotoxic if all precautions recommended by the manufacturer are followed. In high humidity conditions, it may cause damage to fruits and leaves of apple varieties that are particularly sensitive to copper-based products.
Calculation of consumption
Use the Kumir fungicide strictly according to the manufacturer's instructions. Exceeding the recommended concentration may cause:
- the formation of lateral shoots at the roots, which inhibits plant vegetation;
- accumulation of copper in the soil;
- decreased iron absorption;
- leaf dieback on treated crops.
Spraying is done with a working mixture of the product. It is prepared immediately before use and should not be stored for more than 24 hours.
