Fludioxonil inhibits enzymes related to glucose phosphorylation in pathogens. This suppression hinders fungal hyphae growth and leads to pathogen death. When applied as a seed treatment, the active ingredient adsorbs onto the seed surface during stirring and germination. It forms a stable, long-lasting protective barrier. Some of the active ingredient penetrates into the seed interior. This action kills pathogens on the seed surface and those within the seed coat.
Fludioxonil is a highly effective and low-toxicity contact fungicide that does not possess systemic translocation or protective activity. Therefore, it should be applied before or at the early stages of disease development. When used in combination with other systemic fungicides, such as propiconazole, it can broaden the spectrum of disease control and enhance the efficacy of both products.
Metalaxyl-M is a broad-spectrum fungicide that primarily inhibits the synthesis of proteins and ribosomal RNA in fungi. It consists of the highly active R-isomer derived from the two isomers of metalaxyl and exhibits stereoisomeric activity. Metalaxyl-M effectively controls plant diseases caused by downy mildew pathogens, late blight pathogens, and pythium pathogens.
Metalaxyl-M demonstrates higher efficacy than metalaxyl, requiring only 62% of the dosage of metalaxyl while providing a longer residual effect, which significantly enhances safety for both the environment and users. Additionally, Metalaxyl-M degrades faster in soil, further improving its environmental compatibility.
Features of Fludioxonil
1. High Safety
Low Toxicity and Residue: Fludioxonil is relatively safe for crops and the environment, exhibiting low toxicity and low residue. It does not accumulate in plants, thereby avoiding issues of plant resistance that can arise from long-term use. Additionally, it degrades easily in soil and water, preventing long-term environmental pollution.
No Phytotoxicity: Fludioxonil is safe for crops and does not cause phytotoxicity. It can be safely used for seed treatment and soil application on various crops without negatively affecting their growth and development.
2. Highly Effective and Broad-Spectrum Fungicidal Activity
Broad Spectrum: Fludioxonil shows good control efficacy against various soil-borne and seed-borne pathogens, including damping-off, root rot, and gray mold, effectively inhibiting pathogen growth and preventing disease occurrence and spread.
Significant Effect: Fludioxonil excels in reducing diseases such as gray mold, anthracnose, and sclerotinia. It is particularly effective against pathogens caused by Botrytis cinerea, which often infects crops like strawberries, grapes, and cucumbers, leading to fruit rot and leaf wilting. Fludioxonil penetrates deep into the pathogen, disrupting its cellular structure to achieve disease control.
3. Convenient to Use
Diverse Formulations: Fludioxonil comes in various formulations, including seed treatments, soil treatments, and suspension seed coatings, making it easy for farmers to choose the appropriate application method based on their needs. These formulations exhibit good stability and solubility, facilitating field operations.
Flexible Application Methods: Fludioxonil can be applied through seed treatment, soil treatment, or foliar spraying. Farmers can select suitable methods and dosages based on the crop's growth stage and the occurrence of diseases.
4. Unique Mechanism of Action
Inhibiting Pathogen Growth: Fludioxonil inhibits the growth of fungal hyphae by suppressing the transfer of enzymes related to glucose phosphorylation within pathogens, thereby reducing disease incidence. This unique mechanism of action demonstrates Fludioxonil's exceptional activity and stability during the fungicidal process.
5. Long Residual Efficacy
Stable and Long-Lasting: When used as a seed treatment or soil treatment, Fludioxonil provides lasting protection during the early growth stages of crops. It forms a protective barrier in the soil, preventing pathogen invasion and safeguarding root health. This enduring protective effect helps reduce the frequency and severity of disease occurrences.
Features of Metalaxyl-M
1. Strong Systemic Activity
When the agent is sprayed on crops, Metalaxyl-M can be absorbed by seeds, roots, stems, and leaves, and is then translocated to various parts of the plant. This provides effective protection and treatment for the crops.
2. High Safety Profile
Metalaxyl-M is an upgraded version of metalaxyl. Under the same conditions, only half the dosage of metalaxyl is required, enhancing safety for both the environment and the user. It is quickly absorbed by the plant, resistant to rain wash-off, and generally does not cause phytotoxicity.
3. Wide Range of Applications
Metalaxyl-M effectively controls diseases caused by downy mildew, late blight, and pythium. It can be applied to many crops, such as:
- Downy mildew and late blight in melons
- Late blight in tomatoes and potatoes
- Black leg disease in potatoes
- Downy mildew in cabbage
- Late blight in chives
- Downy mildew in onions and spinach
- Late blight in peppers
- Cottony blight in tomatoes
- Downy mildew in grapes
- Damping-off disease in citrus seedlings, etc.
Application of Fludioxonil
Fludioxonil has a broad spectrum of fungicidal activity and demonstrates good control efficacy against various plant pathogens. The main diseases it targets include:
1. Seed-Borne Diseases: Fludioxonil effectively controls various diseases caused by seed-borne pathogens, such as sheath blight, damping-off, and root rot in cereal crops, as well as anthracnose and root rot in leguminous crops. By treating seeds, it can significantly reduce the initial sources of infection, thereby mitigating the severity of subsequent disease outbreaks.
2. Soil-Borne Diseases: Fludioxonil also shows good efficacy against soil-borne diseases, such as late blight in potatoes, wilt in cotton, and stalk rot in corn. These diseases are often transmitted through the soil and can severely impact crop growth. Using Fludioxonil for soil treatment or irrigation can effectively control the spread and proliferation of these diseases.
3. Foliar Diseases: Fludioxonil can be used to control common foliar diseases, such as downy mildew and anthracnose. By applying it through foliar spraying, Fludioxonil can be evenly distributed on the crop leaves, effectively inhibiting the reproduction and spread of pathogens, thus protecting the healthy growth of crops.
