Fludioxonil is a component of pesticides commonly used in agriculture. This ingredient is found in many popular products used to combat a wide range of diseases, including scab, fusarium, and rot. For the product to be effective, it's important to strictly follow the instructions for its use. Safety precautions are also essential.
What are the physical and chemical properties of the drug?
Fludioxonil is produced as transparent, odorless crystals. The substance does not hydrolyze at temperatures of 70°C and a pH of 5-8. The product's key physical properties include the following:
- melting point – +199.5 degrees;
- vapor pressure –3.9∙10-4 megapascals;
- molecular weight – 248.2;
- dissolution in water at a temperature of +25 degrees – 1.8 milligrams per liter.
The fungicide is considered an analogue of natural antifungal agents. It is classified as a broad-spectrum agent. It is relatively stable, but is susceptible to degradation by photolysis.
The substance provides a long-lasting protective effect. It helps disrupt the structure of pathogen cell membranes, which negatively impacts their functioning. The protective period is 30 days. The specific duration depends on the soil type.
Mechanism of operation
Fludioxonil is a broad-spectrum fungicide that inhibits mycelial growth. It is a relatively stable substance, but there is a risk of its destruction during photolysis. The compound exhibits a long-lasting protective effect and a mild systemic effect. It inhibits glucose phosphorylation during cellular respiration.
The composition affects mycelial growth, pathogen proliferation, and cell membrane development. These effects are associated with disruption of cell membrane function.

Purpose
The active substance does not have a toxic effect on cultivated plants.
The product effectively combats pathogens of the Fusarium and TiIletia genera, which cause diseases of cereal seedlings. It also kills pathogens of the Ascochyta, Aspergillus, Helminthosporium, and other genera, which cause diseases in other plants. Products based on this substance are often used for seed dressings.
Thanks to the use of the substance, it is possible to avoid the development of the following pathologies:
- downy mildew;
- various types of rot;
- scab;
- Rhizoctonia;
- helminthosporiosis;
- fusarium.
The substance's broad spectrum of action allows it to be used on a wide variety of plant varieties. It helps destroy pathogens and provides reliable protection against further disease progression or growth retardation.

What medications contain it?
Fludioxonil is a common ingredient found in many medications. The most well-known medications include:
- "Maxim";
- "Deposit";
- "Protect".

Instructions for use
Products containing this substance can be used in various ways—diluted or undiluted. The easiest way is to use the solution. The prepared solution is used for spraying plants or treating tubers. To make a working solution, use 4 milliliters of the active ingredient per 2 liters of water. It is important to use the prepared solution within 24 hours.
For the drug to be effective, you must follow these recommendations:
- Use specialized tools for treatment. Sprayers or etching tools are best. They ensure even distribution of the product.
- Use the composition to treat peeled and healthy seeds and tubers. The main purpose of this product is to prevent the development of pathologies.
- When applying the product, pay attention to the level of exposure. If you only apply it partially, you won't achieve the desired effect.
- This composition should not be used on sprouted planting material. It is recommended to use the product in mid-autumn or early spring.
Precautionary measures
Fludioxonil-based products are considered relatively harmless to humans. If the compound accidentally comes into contact with the skin, it will not cause irritation. However, it is important to ensure that the substance does not enter bodies of water, as it poses a significant risk to fish.
Fludioxonil is an effective chemical that can combat many dangerous diseases. To achieve the desired results, it should be used on planting material.
