Description
Azoxystrobin is a second broad-spectrum strobilurin fungicide. It forms white to beige crystalline solid or powder.

Uses
Strobilurin fungicide; inhibits mitochondrial respiration by blocking electron transfer between cytochromes b and c1. Agricultural fungicide. Azoxystrobin has a very broad spectrum of activity and is active against fungal pathogens from all four taxonomic groups: Oomycetes, Ascomycetes, Deuteromycetes, and Basidiomycetes. It controls diseases on cereals, rice, vines, apples, peaches, bananas, citrus, cucurbits, potatoes, tomatoes, peanuts, coffee, and turf. Azoxystrobin has been processed as a Reduced Risk pesticide for turf uses. Azoxystrobin is a systemic, broad-spectrum fungicide that was first introduced in 1998. It inhibits spore germination and is used on grapevines, cereals, potatoes, apples, bananas, citrus, tomatoes, and other crops. The largest crop uses in California include almonds, rice, pistachios, wine grapes, raisins, and garlic. Among the diseases it controls are rusts, downy mildew, powdery mildew, rice blast, and apple scab. A U.S. EPA Restricted Use Pesticide (RUP).
