Fludioxonil is an active substance that has a fungicidal effect. Thanks to this, it helps to successfully cope with diseases and pests that affect various parts of plants - tubers, stems, foliage, bulbs. However, most often it is used for the prevention of various pathologies. The composition is suitable for treating rhizomes, bulbs, and seed material. It is used before planting in the ground or during storage.
Physical and chemical properties
Fludioxonil comes in the form of transparent crystals that are odorless. The substance is not subject to hydrolysis at a temperature of 70 degrees and pH parameters of 5-8. The main physical characteristics include the following:
- melting parameters - 199.8 degrees;
- molecular weight – 248.2;
- steam pressure 3.9∙10-4 megapascals;
- solubility in water at a temperature of 25 degrees – 1.8 milligrams per 1 liter.
Principle of action on harmful organisms
The fungicide is considered an analogue of natural antimycotic substances. It is a broad-spectrum agent. The composition is considered relatively stable, but can quickly degrade during photolysis.
The compound has a long-lasting protective effect. With its help, it is possible to damage the membranes of pathogen cells, disrupting their functions. The protective effect lasts up to 30 days. It depends on the resistance parameters of the element in a specific type of soil.
In what cases is it used?
In agriculture, the substance is used to combat pathogens that belong to the genus Fusarium and TiIletia and provoke diseases of the sprouts of cereal plants. The composition also helps to cope with representatives of the genus Ascochyta, Altemaria, Fusarium, Aspergillus, Helminthosporium, Rhizoctonia, which cause pathologies in the seedlings of other plants. The substance is often used to treat seed material.
Most often, the element is used to protect planting material from the following diseases and parasites:
- scab;
- dry rot;
- helminthosporiosis;
- molding of bulbs or seed material;
- red or gray rot;
- rhizoctoniasis;
- fusarium;
- peronosporosis.
Due to its wide spectrum of action, the substance is used for different types of crops.It helps control the development of pathogens and protects crops from subsequent diseases or growth abnormalities.
Preparations containing the active substance
Effective products based on fludioxonil include:
- "Deposit";
- "Scarlet";
- "Maksim";
- "Protect".
How to use
The substance can be applied in diluted or undiluted form. The easiest way to apply it is with a chemical mixed with water. It is permissible to spray plants or treat tubers with a ready-made product. To prepare the working fluid for 2 liters of water, you need to take 4 milliliters of the substance. The finished composition should be used within 24 hours.
In order for the product to give the desired effect, it is important to follow the following rules:
- Process only healthy and clean seeds and tubers. The main purpose of the product is to prevent the development of diseases.
- For processing it is necessary to use special tools. These can be pickling machines or spray guns. They help to evenly apply the product to the raw materials.
- During processing, it is important to monitor the degree of exposure to the substance. Partial application of the product will not give noticeable results.
- Sprouted seeds or flower tubers must not be treated with the product. It is best to apply it in mid-autumn or early spring.
An important feature of the substance is the duration of its effect. The drug remains active in soil for 12 weeks.
Safety
The substance is considered safe for humans. In case of accidental contact with the skin, it does not cause irritation. However, it is important to avoid penetration of the aqueous solution into bodies of water. It poses a great danger to fish. Therefore, it is forbidden to drain the remaining working fluid into lakes or rivers.
After completing the treatment, it is important to thoroughly wash the containers and tools that were used to prepare the solution. It is strictly prohibited to use food utensils for this purpose.
Fludioxonil is considered an effective and harmless product that is actively used in agriculture. With its help, it is possible to prevent the development of many dangerous pathologies even before planting plants in the ground.
