Fungi can be a devastating development. When found on residential lawns, it can be quite an ugly sight to see and embarrassing. 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 which works exceptionally well is azoxystrobin.

On this page we will give you an overview of azoxystrobin, its origin and why it works so well to eliminate fungi. Here you can also shop the fungicide products we have in stock which contain this active ingredient.

What is Azoxystrobin?

Azoxystrobin is a broad spectrum fungicide used for protecting plants and food crops from foliar and soil-borne fungal diseases. Azoxystrobin is the first of a new class of pesticidal compounds called ß-methoxyacrylates, which are derived from the naturally-occurring strobilurins. At this time, azoxystrobin is the only fungicide able to provide protection against all four major groups of fungal diseases.

Azoxystrobin was discovered in the midst of research being conducted on some fungal mushrooms commonly found in the forests of Europe. These small mushrooms were particularly fascinating to scientists due to their strong ability to defend themselves. Their defense mechanism is 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. It is a restricted use pesticide first introduced in 1998.

How does Azoxystrobin Work?

The mode of action of azoxystrobin is the prevention of respiration for the fungi due to the disruption of electron transport chain. As a result this preventing ATP synthesis (this occurs as the azoxystrobin binds to the Qo site of Complex III within the mitochondrion). Azoxystrobin is a systemic fungicide. It slowly works its way up through the plant roots and into all the parts of the plant, inhibiting mitochondrial respiration in fungi. This prevents spore germination and fungus growth.

How is Azoxystrobin Used?

Azoxystrobin is used widely in agricultural farms overseas but sees limited usage in the US. It has been known to also be used on golf courses and commercial lands. Some of the fungal diseases it has been known to successfully eliminate is  Anthracnose, Brown Patch, various Snow Mold, Leafspot, and Summer Patch among others.


Outside the U.S., azoxystrobin has been used to protect cereals, cucurbits, vegetables, fruit crops, peanuts, turf, ornamentals, stone fruit, bananas, rice, apples, grapes, potatoes and other crops from fungal diseases.


Is Azoxystrobin Safe To Use?

Azoxystrobin has low toxicity for mammals, birds, bees, insects, and earthworms. Toxicity for freshwater fish is high. Azoxystrobin is also very toxic to Macintosh apple trees and may damage crabapples.


As with any of our chemicals we carry, we highly recommended wearing personal protective equipment required to lessen the risks of inhaling, ingesting or coming in contact with the skin. The minimum PPE suggested when handling azoxystrobin based products includes chemical resistant gloves, eye protection, and long sleeved clothing. Please make sure to follow the label instructions for the proper directions in applying the product and knowing what safety measures to apply.
