In the field of agriculture, with the increase of pathogenic bacterial resistance and the complexity of disease types, the search for efficient, broad-spectrum and environmentally friendly fungicides has become a top priority for agricultural consumers.
Fluoroxystrobin, as a new type of methoxyacrylate fungicide, has quickly occupied a place in the agricultural market since its launch in 2004 with its unique mechanism of action, excellent application characteristics and extensive disease prevention and control capabilities. Whether it is market coverage or agricultural material consumption, it has always been in the first place of similar products in the market.
On March 29, 2024, the Pesticide Control Institute of the Ministry of Agriculture and Rural Affairs announced the announcement of the third batch of approved pesticide registration in 2024.
Among them, there are three varieties of "fluoroxystrobin" of Jiangsu Good Harvest Wayne Company, namely 94% fluoxystrobin, 43% fluoroxystrobin, tebuconazole suspension, and 51% fluoropyrobin chlorothalonil suspension. It is the first time that a domestic enterprise has registered "fluoroxystrobin" related agricultural products. That is to say, before that, the "fluoxystrobin" agricultural products sold in the agricultural market and used by agricultural consumers were all imported agricultural products.

In this issue, Qingjiang Crane will focus on and chat with all of you and teachers about the new agricultural products "methoxyacrylate fungicide ~ fluoroxystrobin" related topics.
I hope that through the sharing of this article, I will take you to deeply discuss and exchange the mechanism of action, characteristics, application advantages and the types of diseases that fluoroxystrobin can be prevented and controlled. I hope you like and actively participate in the interactive comments, forward and share the pictures and texts of this issue.
Mechanism and characteristics of fluoxystrobin:
01) Mechanism of action of "fluoxystrobin".
Like azoxystrobin and other "methoxyacrylate fungicides", the core mechanism of action of fluazrobin lies in its function as a mitochondrial respiratory inhibitor.
Specifically, it blocks the production of ATP (energy required by the cell) by binding to the Qo site of cytochrome b in cytochrome b and cl complex III., preventing electron transfer in the electron transport chain, interfering with energy circulation in the fungal body, and ultimately leading to cell death.

This mechanism of action is different from that of most previous fungicides, especially its site of action against cytochrome B, which allows fluoroxystrobin to remain highly effective against a variety of strains that have developed resistance (protective plus therapeutic effect).
02) Characteristics of "fluoxystrobin".
"Fluoxystrobin" is a broad-spectrum fungicide, which shows good control effect on almost all fungal diseases (ascomycetes, basidiomycetes, oomycetes and semi-known fungi).
For example, the fungal diseases "powdery mildew", "sclerotinia sclerotinia" and "white mold" in the "Ascomycetes". Fungal diseases in the "basidiomycetes" are "fibrocleosis" and "embroidery". Fungal diseases in the "oomycetes" "Pythium", "late blight", "downy mildew", etc. "Semi-known fungi" fungal diseases such as "brown spot", "large spot", "small spot", "gray spot" and "anthracnose".
Secondly, fluazrobin has the dual characteristics of fast acting and long duration of effect, which can quickly inhibit spore germination and mycelial growth in the early stage of disease, and can also maintain a stable control effect for a long time.

In addition, the systemic activity of fluazoxystrobin is excellent, and the agent can be quickly absorbed by the plant and evenly penetrated and distributed in all parts of the plant, which improves the immunity of the plant and enhances the resistance of the agent to rain washing on the surface of the object.
Advantages of "fluazrobin" in production:
01) Flexibility in the application of "fluoxystrobin".
Fluoxystrobin can be used in a variety of ways, both as stem and leaf treatments and as a seed treatment. However, it is mainly based on "stem and leaf treatment".
In terms of stem and leaf treatment, "fluoroxystrobin" provides excellent protection and therapeutic effects in the early stages of fungal infection, such as spore germination, germination tube growth, and leaf invasion.
When used as seed treatment, although the absorption capacity of "fluoxystrobin" agent through seeds and roots is relatively weak, it has a significant killing and lasting effect on seedlings and seed-borne and soil-borne diseases.

02) "Fluoroxystrobin" has the characteristics of being environmentally friendly.
Fluazrobin shows good compatibility with crops and the environment, and is safe for crops when used at recommended doses, while the impact on groundwater and the ecological environment is relatively small.
In addition, after the expiration of the compound patent of fluazrobin, many domestic enterprises have carried out field trials and demonstrations of fluazrobin single agent and compound preparation, which further promoted the application and development of "halostrobin" in the domestic market.

03) "Fluoroxystrobin" has a potential blending advantage.
Fluoxystrobin can be used in combination with other fungicides to exert significant synergies.
For example, the mixture of "fluazrobin" with oxazoxidodone, oxystrobin, rice blastamide and other fungicides not only improves the control effect, but also overcomes the resistance of the bacteria and reduces the cost of pesticide use. This blending strategy makes fluoxystrobin more flexible and efficient in different crops and disease control.

In addition, "fluoxystrobin" also has compound preparations with fungicides such as "tebuconazole", "prothioconazole", "chlorothalonil", "mycloconazole", "powderazole" and "downy mildew". It is also possible to use a single dose in the compound preparation for two-dimensional or multi-compound compounding, and the effect is better when using stems and leaves.
The main products of "fluoxystrobin" sold in the agricultural materials market are:
01) The original drug of "fluoxystrobin":
There are 94% fluoxystrobin TC and 98.5% fluoroxystrobin TC registered products.
02) Single-dose product of "Fluoxystrobin":
10% fluoroxystrobin EC, 48% fluoroxystrobin EC.

03) The compound preparations of "fluoxystrobin" are:
7.5% fluazrobin prothioconazole EC (of which "fluoroxystrobin" accounts for 3.75%), 20% fluoroxystrobin prothioconazole EC (of which "fluoroxystrobin" accounts for 10%), 40.84% fluoroxystrobin chlorothalonil suspension (of which "fluoroxystrobin" accounts for 2.44%), 41.41% fluoroxystrobin mycloconazole suspension (of which "fluoroxystrobin" accounts for 15.81%), 43% fluoroxystrobin tebuconazole suspension (of which "fluoroxystrobin" accounts for 18%), 51% Fluoroxystrobin chlorothalonil suspension (of which "fluoroxystrobin" accounts for 4.6%).
Fluoroxystrobin can be controlled by the following diseases:
The broad-spectrum bactericidal activity of halostrostin makes it effective in the prevention and control of a variety of fungal diseases. After test demonstration, "halostrobin" can be used for the prevention and treatment of more than 40 crops and more than 100 kinds of fungal diseases, and the effect is very good.
For example, in cereal crops, fluoxystrobin has excellent control effects on leaf spot, glue blight, brown rust, stripe rust, moire, brown spot, net spot and powdery mildew and other diseases.

On potatoes, fluoxystrobin has significant control effect on early blight, late blight and downy mildew. In vegetable crops, halostrostin also has excellent control effect on leaf spot, downy mildew and other diseases. In addition, fluoxystrobin also has a good control effect on coffee rust, citrus tree scab, corn large (small) spot, peanut brown spot and other diseases.
Words written at the end:
In summary, as a new methoxyacrylate fungicide, fluoxystrobin has shown strong market potential and use value in agricultural disease prevention and control with its unique mechanism of action, broad-spectrum bactericidal activity, excellent systemic conductivity, environmental friendliness and application flexibility.
With the gradual enrichment of dosage forms and compound combinations, halostrostrobin will usher in a broader application and consumption prospect in the domestic and foreign agricultural material consumption markets and even the world in the future.
