Cas no 131860-33-8 (Azoxystrobin)

Azoxystrobin is a broad-spectrum fungicide belonging to the strobilurin class, widely used in agriculture to protect crops against fungal pathogens. It exhibits both protective and curative activity, inhibiting mitochondrial respiration by blocking electron transfer at the cytochrome bc1 complex. Azoxystrobin is effective against a diverse range of fungi, including Ascomycetes, Basidiomycetes, and Deuteromycetes. Its systemic and translaminar properties ensure thorough plant coverage and residual activity. The compound is noted for its low mammalian toxicity and favorable environmental profile, including minimal impact on non-target organisms. Azoxystrobin is compatible with integrated pest management (IPM) programs and is commonly applied to cereals, fruits, vegetables, and turf.

Azoxystrobin (CAS No. 131860-33-8): A Comprehensive Guide to the Leading Fungicide

Azoxystrobin (CAS No. 131860-33-8) is a highly effective broad-spectrum fungicide belonging to the strobilurin class of compounds. First introduced in the 1990s, it has become one of the most widely used agricultural fungicides globally due to its unique mode of action and environmental profile. The compound was developed by Syngenta (formerly Zeneca Agrochemicals) and is marketed under various trade names including Amistar, Heritage, and Quadris.

The chemical name of azoxystrobin is methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate. This systemic fungicide works by inhibiting mitochondrial respiration in fungi, specifically targeting the quinone outside site (Qo site) of cytochrome bc1 complex. This mechanism makes it particularly effective against a wide range of fungal pathogens while maintaining low toxicity to mammals.

One of the key advantages of azoxystrobin fungicide is its translaminar movement within plants, providing both protective and curative action. Farmers and agronomists frequently search for information about "azoxystrobin mode of action" and "how does azoxystrobin work", reflecting the professional interest in its unique biochemical properties. The compound demonstrates excellent activity against major crop diseases including powdery mildews, rusts, leaf spots, and blights in various crops.

The azoxystrobin market has grown significantly in recent years, driven by increasing demand for high-efficiency crop protection solutions. With the global push toward sustainable agriculture, questions like "is azoxystrobin organic" and "azoxystrobin environmental impact" have become trending search terms. While not certified for organic farming, azoxystrobin is considered relatively environmentally friendly compared to many older fungicides, with low mammalian toxicity and moderate persistence in soil.

Application methods for azoxystrobin vary depending on the target crop and disease. Common formulations include azoxystrobin SC (suspension concentrate), azoxystrobin WG (water-dispersible granules), and combination products with other active ingredients. Farmers often search for "azoxystrobin application rates" and "azoxystrobin mixing compatibility", highlighting the practical considerations in field use.

Recent research has explored the plant health benefits of azoxystrobin beyond its fungicidal activity. Studies suggest it may enhance crop yield and stress tolerance through physiological effects on treated plants. This has led to increased interest in "azoxystrobin plant growth effects" among researchers and progressive growers.

In terms of crop safety, azoxystrobin is generally well-tolerated by most plants when used according to label recommendations. However, questions about "azoxystrobin phytotoxicity" occasionally arise, particularly regarding sensitive varieties or adverse weather conditions during application.

The global azoxystrobin industry faces evolving challenges, including fungicide resistance management. Search trends show growing interest in "azoxystrobin resistance" and "azoxystrobin rotation partners", reflecting the agricultural community's awareness of stewardship practices to preserve the efficacy of this valuable tool.

From a regulatory perspective, azoxystrobin has been extensively evaluated by authorities worldwide. It is registered in most major agricultural markets, though specific azoxystrobin restrictions and azoxystrobin re-entry intervals vary by region. Professionals often search for "azoxystrobin label requirements" to ensure compliance with local regulations.

Looking to the future, azoxystrobin innovations continue to emerge, including improved formulations and combination products. The development of azoxystrobin nanoformulations represents one promising area of research that could enhance performance while reducing environmental loading.

For agricultural professionals seeking detailed technical information, resources on "azoxystrobin solubility", "azoxystrobin half-life", and "azoxystrobin spectrum of activity" remain consistently popular. These parameters are crucial for understanding the compound's behavior in different environmental conditions and against various pathogen species.

In conclusion, azoxystrobin (CAS No. 131860-33-8) remains a cornerstone of modern fungicide programs worldwide. Its combination of broad-spectrum efficacy, favorable environmental profile, and potential plant health benefits ensure its continued importance in integrated pest management systems. As agricultural practices evolve to meet sustainability challenges, azoxystrobin will likely maintain its position as one of the most researched and utilized fungicides in professional crop protection.
