Azoxystrobin Fungicide: Usage Guide

Azoxystrobin is a new fungicide with a novel biochemical mode of action. Its synthesis was inspired by a group of natural products, the strobilurins, which are produced by several species of Basidiomycete fungi, which grow on decaying wood. The structures of azoxystrobin, Strobilurin A and the closely related Oudemansin A, The natural products and azoxystrobin share a common structural feature, namely the methyl ester of β-methoxyacrylic acid.

Fungi can be a devastating development. When found on residential lawns, it is an embarrassing and ugly sight to see. On agricultural lands, fungi can ruin crops and hurt the economy. For these reasons, fungicides were developed to deal with fungus issues. One such fungicide active ingredient which works exceptionally well is Azoxystrobin.


Azoxystrobin is a systemic fungicide used for the protection of plants and crops from harmful fungal diseases. Azoxystrobin is part of a class of chemicals known as ß-methoxyacrylates, which are derived from the naturally-occurring compounds and are used mostly in agricultural settings. At this time, Azoxystrobin is the only fungicide with the ability to offer protection against the four major types of plant fungi. Azoxystrobin was first discovered in the midst of research being conducted on fungal mushrooms commonly found in the forests of Europe. These small mushrooms fascinated scientists due to their strong ability to defend themselves.

It was found that the defense mechanism of the mushrooms were based on the secretion of two substances, strobilurin A and oudemansin A. These substances gave the fungi the ability to keep their competitors at bay and kill them when in range. Observations of this mechanism led to research that resulted in the development of Azoxystrobin fungicide.

Features of Azoxystrobin Fungicide

  • Broad Spectrum Control of Diseases, a Single solution for a number of diseases.
  • Multifunctional Action-Can be used as Protective, Curative & Eradicative.
  • Its translaminar & systemic movement inhibits new growth of fungus after spray.
  • It is quickly absorbed by plants & rapidly enters in plant system & starts working.
  • It gives longer duration control thus reduces the number of sprays for the farmer.
  • Its dual site action is a perfect fit for resistance management.

Mode of Action

The mode of action of Azoxystrobin is by choking out fungi via interrupting the activity of the electron transport chain. As a result, this prevents fungal spores from germinating and halts the growth process of the fungus. 

Benefits of Azoxystrobin

Azoxystrobin is a systemic fungicide and can be used for preventative and curative control of certain common fungal diseases. Once sprayed on a target area, it works through the plant roots and travels throughout the entire plant to suppress fungal growth. Most Azoxystrobin products can control diseases for up to 28 days or more.

Use Azoxystrobin fungicides when you want systemic treatment of a broad range of labeled fungal diseases.

  1. My home is surrounded by 200 acres of farmland crops — gmo soy and corn commercial crops. Recently, a crop-spraying plane sprayed the fields beyond by surrounding tree line 50 to 100 feet from my door. After reading the information here about Azoxystrobin I feel that perhaps it is not harmful to people. Is this true?

    Also, the other ingredients conbined and sprayed with it are Propiconatole and Pydiflumetofen (18.3 % active). It is a Syngenta company USA product. Two other names given were Miravisneo and Veltyma which may be proprietary names (not sure) for this resistance group 11, 3, 7 Fungicide. My proximity to the sprayed chemicals leads me to question its safety for me and my family in regards, to air, soil and water.

    Can anyone help me with your knowlege and opinion? Thank you in advance. Kind regards.

    • Hello Sandra, The specification of the farm provided indicates that the farm is a commercial farm. I presume the farmer would follow the Good Agricultural Practices (GAP) which includes following the recommended application rate of the fungicides. This rate is not harmful to the ecosystem.

      Also, I would want to know if you have reports of contamination of water and air as a result of the farm activities in the past. If the answer to this is NO, then, with these assertions, I want to tell you that you are safe.
