Rate per acre Staging and specific comments
Canola
Virulent blackleg
(
Leptosphaeria maculans
)
202
mL
Apply at the 2 - 6 leaf stage. Maximum of 2 applications per
season.
Sclerotinia stem rot
(

higher rate if there is a history of Sclerotinia infection in the area,
and when environmental conditions favour disease development.
Alternaria black spot
(
Alternaria brassicae,
Alternaria raphani
)
202
mL
Apply at the pod stage (90% petal fall).
Chickpea
Ascochyta blight (
Ascochyta
spp.)
202
mL
Apply at the first sign of disease and no later than the onset
of flowering, followed by a 2nd application 10 - 14 days later.
Maximum of 2 applications per season.
Corn
Rust (
Puccinia sorghi
)
183
mL in 80 L
of water/acre.
Apply prior to disease establishment and subsequently at a 7 - 14
day interval. Apply a maximum of 2 applications per season.

Potatoes
(
foliar)
Early blight (
Alternaria solani
)
202 - 324
mL
For early blight, use the high rate and short application interval
under high disease pressures. If late blight becomes established,
discontinue use of Quadris and use alternative fungicides.
Late blight (
Phytophthora
infestans
)
324
mL
Black dot (
Colletotrichum
coccodes
)
500 - 800
mL Apply on a 7 - 14 day interval, starting prior to disease
establishment.
Potatoes (in

Silver scurf (
Helminthosporium
solani
)
4 - 6
mL
product/
100
m row
Apply once as an in furrow spray in 20 - 56 L/acre. Mount the
