Fandango

Fandango is a systemic emulsifiable concentrate fungicide from Bayer that pairs two active ingredients, fluoxastrobin (100 g/L), a broad-spectrum strobilurin, and prothioconazole (100 g/L), a triazole. Together they disrupt fungal respiration and ergosterol synthesis, giving locally systemic and acropetal protection. It controls downy mildew (Peronospora destructor), Stemphylium leaf spot and rust in onion crops grown for bulbs. Apply preventively at 1.25 L/ha, alternating with other fungicides; it is rainfast within one hour.
