For control of cleavers at the 4 to 6-whorl growth stage and suppression of giant ragweed and spreading atriplex, add ammonium sulphate at 500 g/ha
(99%)
or 1 L/ha (49% solution). If using an ammonium sulphate product with a different concentration, adjust the rate accordingly.

Application Information
How to Apply
:
With ground equipment or aircraft.
Water Volume
:. 20 - 40
L/acre - ground, a minimum of 12.1 L/acre by aircraft.
Application Tips
For optimum control, apply Axial iPak herbicide to actively growing weeds, ideally at the 2 - 3 leaf stage. An early
application will maximize crop yields by reducing weed competition. Weeds emerging after application of Axial
iPak herbicide will not be controlled. Weed control following application of Axial iPak herbicide can be reduced or
delayed under stress conditions such as drought, heat, insufficient fertility, flooding or prolonged cool temperatures.
Grass escapes or re-tillering may occur if application is made during prolonged stress conditions. Optimum weed
control will be obtained if application of Axial iPak herbicide is delayed until the stress conditions have ended, and
weeds are once again actively growing. Do not apply to crop that is stressed by conditions such as frost, low fertility,
drought, flooding, disease or insect damage as crop injury may result.
How it Works
Pinoxaden herbicide is absorbed by the leaves and is rapidly translocated to the growing points of leaves and stems.
Thorough coverage of the plants is essential for consistent control. Pyrasulfotole is absorbed through leaves and
is translocated to meristematic regions where it inhibits the HPPD enzyme. Pyrasulfotole inhibits plant pigment
biosynthesis and photosynthesis.
Expected Results
Actively growing susceptible grasses stop growing within 48 hours of treatment. Depending on species, growing
conditions and crop competition, leaves and growing points turn yellow within one to three weeks after application.
Further colour changes and loss of vigour will be observed, followed by a browning and control three to five weeks
after application. Small burnt spots on the broadleaf weeds can appear in hours. Lack of plant pigments shuts down
the photosynthetic pathway resulting in bleaching symptoms and rapid death, normally in 6 - 14 days.
Restrictions
Rainfall
:
Axial iPak herbicides can be used one hour before rainfall.
Grazing
:
Observe a minimum of 25 days before grazing livestock on crops treated with Axial iPak herbicides.
Pre-harvest Interval
: 60
days after treatment for grain and straw and 30 days after treatment for hay.
Re-cropping Restrictions
:
Lentils should not be seeded for 22 months after application of Axial iPak herbicides.
Do not plant field peas the year following an Axial iPak herbicide application in the Brown soil zone where organic
matter content is below 2.5% and where soil pH is above 7.5.
