Crops, Diseases Controlled, Rates and Timing
Crops
Diseases
Rate per acre Timing and comments
Barley
Fusarium Head Blight
(
Fusaiuim
spp.) or
scab (suppression
only)
128 - 170
mL
Apply when 70 - 100% of the barley main stem heads are fully emerged to
3
days after full head emergence.
Application of the 170 mL/acre rate is suggested in situations where disease
pressure is expected to be high. This may occur when prolonged periods
of warm wet weather are forecast during barley head emergence, when
barley and wheat is grown in a crop rotation that has contained corn or when
susceptible cultivars are grown.
Net blotch
(
Pyrenophora
teres
),
scald
(
Rhynchosporium
secalis
),
spot blotch
(
Cochliobolus sativus
)
85 - 128
mL
Apply as a preventive foliar spray when the earliest disease symptoms
appear on the leaves and stems. Barley fields should be observed closely for
early disease symptoms, particularly when susceptible varieties are planted
and/or under prolonged conditions favorable for disease development.
Maximum of 2 applications per season; minimal spray interval of 7 days.
Wheat
Fusarium Head Blight
(
Fusaiuim
spp.) or
scab
(
suppression only)
128 - 170
mL
Fusarium head blight or control of glume blotch: apply within the time period
from when at least 75% of the wheat heads on the main stem are fully
emerged to when 50% of the heads on the main stem are in flower. Use of
higher rate (170 mL/acre) will typically provide highest levels of mycotoxin
reduction.
Glume blotch
(
Stagonosora
nodorum
)
128 - 170
mL
Speckled leaf
blotch (
Septoria
tritici
),
tan spot
(
Pyrenophora tritici-
repentis
),
leaf rust
(
Pucciniarecondata
)
128
mL
Observe crop closely, and apply Proline as a preventative foliar spray when
the earliest disease symptoms appear on the leaves and stems. Maximum
of 2 applications per season. Minimum spray interval of 7 days between
applications.
Oats
Crown rust
128
mL
Apply as a preventive foliar spray when the earliest disease symptoms
appear on the leaves and stems. Oat fields should be observed closely
for early disease symptoms, particularly when susceptible varieties are
planted and/or under prolonged conditions that favour disease development.
Maximum of 2 applications per season. Minimum spray interval of 7 days.
