Apply Priaxor DS at beginning of flowering or at the
onset of disease symptoms. Use the 160mL/acre
rate to obtain extended protection with maximum
yield benefits.
If disease persists or weather conditions are
favourable for disease development, make a second
application 10 - 14 days later with a fungicide that
contains a different mode of action.

Application Information
How to Apply
:
Ground and aerial application.
Water volume
:
Ground: 40 L/acre minimum. Aerial: 20 L/acre minimum.
Application Tips
Good coverage is essential for effective disease control, and higher water volumes tend to increase performance with
dense canopies. Priaxor DS works best if it is applied in a preventative manner prior to the development of disease.
Do not apply more than 1 application of this product before alternating to a fungicide with an alternative mode of
action.
How it Works
The active ingredient fluxapyroxad is a carboximide (SDHI) fungicide with systemic activity. The active ingredient
pyraclostrobin is a member of the strobilurin class of chemistry used as a broad spectrum fungicide.
Restrictions
Effects of rainfall
:
Avoid application when heavy rain is forecast. Rainfast in 1 hour.
Grazing
:
All crops can be grazed or fed to livestock.
Pre-harvest interval
: 30
days.
Re-cropping
:
Tuberous and corm vegetables, sugar beets, legume vegetables, pome fruits, stone fruits, cereals and
oilseeds may be planted immediately following the last application. A plant-back interval of one year is required for
all other crops.
Environmental Precautions
Observe buffer zones specified on the label. The use of this chemical may result in contamination of groundwater
particularly in areas where soils are permeable (e.g. sandy soils) and/or depth of the water table is shallow. Toxic to
aquatic organisms, small mammals and non-target terrestrial plants.
