Azoxystrobin is a broad spectrum fungicide of the class of synthetic compounds called β-methoxyacrylates. These chemicals are derived from naturally occurring strobilurins, highly effective phytotoxic compounds produced by two species of mushrooms found naturally in Czech forests. Azoxystrobin can be applied as a foliar spray or a soil-treatment prior to planting, as it has a residual effect. It acts as a systemic fungicide which has curative, translaminar and preventative action. The mode of action of azoxystrobin is to prevent the respiration of fungi due to the disruption of electron transport chain, preventing ATP synthesis (this occurs as the azoxystrobin binds to the Qo site of Complex III within the mitochondrion). Azoxystrobin has the broadest spectrum of any antifungal treatment, and it is effective against all 4 major groups of fungi – the Ascomycota, Deuteromycota, Basidiomycota and the Oomycota. It is therefore able to prevent or cure powdery mildew, downy mildew, rust and and rice blast diseases. Azoxystrobin is approved for use on a wide variety of crops in the United Kingdom, including asparagus, barley, broccoli, calabrese, brussels sprouts, onions, cabbages, carrots, cauliflowers, collards, combining peas, field beans, kales, leeks, oats, oilseed rape, potatoes, rye, triticale, vining peas and wheat . It is also approved for use of amenity turf such as golf courses, lawns and football pitches. Azoxystrobin is sold in the formulation of water dispersible granules and as a suspension concentrate in several concentrations. It is mostly used alone, although azoxystrobin can be combined with chlorothalonil, fenpropimorph, cyproconazole and propiconazole.
