Azoxystrobin is a systemic fungicide, active against Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes. It has preventative, curative and translaminar properties and residual activity lasting for up to eight weeks on cereals. The product demonstrates slow, steady foliar uptake and moves only in the xylem. Azoxystrobin inhibits mycelial growth and also has anti-sporulant activity. It is particularly effective at the early stages of fungal development (especially at spore germination) due to its inhibition of energy production.
