Fludioxonil: description and principle of action, fungicides with it and how to apply

Fludioxonil is called an effective substance that has a fungicidal effect. Thanks to this, it helps to successfully cope with diseases and pests that affect various fragments of plants - tubers, stems, foliage, bulbs. However, most often it is used to prevent various pathologies. The composition is suitable for dressing rhizomes, bulbs, seeds. It is used before planting in the ground or during storage.

Physical and chemical properties

Fludioxonil is available as clear crystals that are odorless. The substance is not subject to hydrolysis at a temperature of 70 degrees and pH 5-8. The main physical characteristics include the following:

• melting parameters - 199.8 degrees;
• molecular weight - 248.2;
• vapor pressure 3.9∙10-4 megapascals;
• solubility in water at a temperature of 25 degrees - 1.8 milligrams per 1 liter.

Pest action principle

Fungicide is considered an analogue of natural antimycotic substances. It is a broad spectrum agent. The composition is considered relatively stable, but can be rapidly destroyed during photolysis.

Compound has a long protective effect. With its help, it is possible to damage the membranes of pathogen cells, disrupting their functions. The term of the protective effect reaches 30 days. It depends on the resistance parameters of the element in a particular type of soil.

When used

In agriculture, the substance is used to combat pathogens that belong to the genus Fusarium and TiIletia and provoke diseases of cereal plant sprouts.The composition also helps to cope with representatives of the genus Ascochyta, Altemaria, Fusarium, Aspergillus, Helminthosporium, Rhizoctonia, which cause pathologies in 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;
• helminthosporiasis;
• mold bulbs or seed material;
• red or gray rot;
• rhizoctoniosis;
• fusarium;
• peronosporosis.

Due to a 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 failures.

Preparations containing the active ingredient

Effective fludioxonil-based products include:

• "Deposit";
• "Crimson";
• "Maxim";
• Protekt.

How to use

The substance can be applied diluted and undiluted. The easiest way to apply it is based on a chemical mixed with water. It is permissible to spray plants or treat tubers with a ready-made product. To prepare a working fluid for 2 liters of water, you need to take 4 milliliters of the substance. The finished composition should be used within a day.

For the remedy to give the desired effect, it is important to follow the following rules:

1. Process only he althy and clean seeds and tubers. The main purpose of the remedy is the prevention of the development of diseases.
2. For processing it is worth using special tools. These can be pickling machines or spray guns. They help to evenly apply the product to the raw material.
3. During processing, it is important to monitor the degree of exposure to the substance. Partial application of the product will not give noticeable results.
4. Sprouted seeds or flower tubers are not allowed to be treated with the product. It is best applied in the middle of autumn or early spring.

An important feature of a substance is the duration of its effect. The drug remains active in the soil for 12 weeks.

This substance is perfectly acceptable to be mixed with other products. Fludioxonil combines well with metalaxyl, furatiocarb, cypronidil. It is also allowed to combine it with oxolinic acid and difenoconazole. However, before using different products at the same time, it is important to evaluate their compatibility.

Safety

The substance is considered safe for humans. In case of accidental contact with the skin, it does not provoke irritation. However, it is important to avoid the penetration of an aqueous solution into water bodies. It poses a great danger to fish. Therefore, it is forbidden to drain the remains of the working fluid into lakes or rivers.

After completing the treatment, it is important to wash the containers and tools that were used to prepare the solution well. For this purpose, it is strictly forbidden to use food utensils.

Fludioxonil is considered an effective and harmless remedy 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.
