Famoxadone is an oxazolidinedione
fungicide. Although famoxadone is not a strobilurin
derivative, it shares the same mechanism of action. Famoxadone provides control of a broad spectrum of
fungi but is particularly effective against downy mildew
(P. viticola), late and early blights (Phytophthora infestans
and Alternaria solani), the Septoria complex, and barley
net blotch at rates of 50 to 200 g ai/ha. Target crops include
vines, potatoes/tomatoes, cereals, sugar beets, canola, and
cucumber. It shows good protectant, translaminar and residual control, with excellent rainfastness and good crop
safety. As was seen for trifloxystrobin, it is particularly
effective against grape downy mildew when applied in
mixture with cymoxanil. The cereal disease spectrum and
level of disease control are improved when famoxadone is
mixed with triazole fungicides such as flusilazole.
