Rate per acre Timing and comments
Canola,
rapeseed,
oriental
mustard
Sclerotinia stem rot
(
Sclerotinia
sclerotiorum
)
128 - 149
mL
Apply when the canola crop is in the 20 - 50% bloom stage. Best protection
will be achieved when the fungicide is applied prior to petals beginning to fall
and will allow for the maximum number of petals to be protected.
The 149 mL/acre rate is recommended for fields with a history of heavy
disease pressure or for dense crop stands.
A second application at 128 mL/acre may be applied 7 - 10 days after the first
application - up to full bloom stage of canola, if disease persists or weather
conditions are favourable for development of disease. When conditions
favouring disease are severe, use the shorter spray interval.
Good spray coverage of the plants is essential.
Flax
Sclerotinia stem rot
(
Sclerotinia
sclerotiorum
)
128 - 149
mL
Apply when the crop is in the 20 - 50% bloom stage. Best protection will be
achieved when the fungicide is applied prior to petals beginning to fall and
will allow for the maximum number of petals to be protected. The higher rate
is recommended for fields with a history of heavy disease pressure or for
dense crop stands. Good spray coverage of the plants is essential.
Chickpea
Ascochyta blight
(
Ascochyta rabiei
)
128 - 170
mL
Apply at the first sign of disease. Maximum three applications per year.
Lentil
Ascochyta blight
(
Ascochyta
spp.)
128 - 170
mL
Apply at the first sign of disease. Maximum two applications per year.
Corn (field,
sweet and
popcorn)

Gibberella ear rots

Gibeberella spp
)

Rusts (
Puccinia sorgh,

Eyespot (

)
Northern Blight
(
Setosphaeria turcicia
)
170
mL
Fusarium ear rot outbreaks occur when the weather is warm and wet during
silking. For optimum suppression of ear rot apply from the development stage
of corn between stigmata visible (silking, BBCH 63) to the stigmata drying
(
silk browning, BBCH 67).
To achieve thorough cob coverage using ground equipment, drop nozzles are
recommended.
Maximum of one application per season.
Soybean
Asian soybean
rust (
Phakopsora
pachyrhizi
)
Frogeye leaf spot
(
Cercospora sojina
)
85
mL
Apply when disease symptoms are present or the risk of infection is
imminent.
Maximum of one application per season.
Sugar
beets
Cercospora leaf spot
(
Cercospora beticola
)
128 - 168
mL Apply at first sign of disease. Use the higher rate when conditions are
favourable for severe disease pressure. Maximum of 3 applications per crop
year. Repeat applications as needed using a 14 - 21 day interval depending on
disease pressure.
Rhizoctonia crown rot
(
Rhizoctonia solani
)
(
soil borne disease)
168
mL
Apply at the 4 leaf stage to row closure growth stage. Repeat applications as
needed using a 21 day spray interval.
Registered Tank Mixes
