HERBICIDE
4FARMERS 1-PYR 750
WG
Herbicide
is
a member
of
the imidazolinone group
of
herbicides. 4FARMERS 1-PYR 750
WG
Herbicide has the inhibition
of
acetolactante
synthase (ALS) mode
of
action. For weed resistance management, 4F
ARMERS 1-PYR 750
WG
Herbicide is a Group B herbicide. Some naturally occurring weed
biotypes resistant to
4FARMERS 1-PYR 750
WG
Herbicide and other Group B herbicides may exist through
normal genetic variability
iu
any weed population. The resistant individuals can eventually
dominate the weed population
if
these herbicides are used repeatedly. These resistant weeds
will not be controlled
by
4FARMERS I-PYR 750 WG Herbicide or other Group B herbicides.
Since the occurrence
of
resistant weeds is difficult
to
detect prior
to
use, 4Farmers Australia
Ply
Ltd accepts
no
liability for any losses that may result from failure
of
4F ARMERS 1-PYR
750 WG Herbicide
_to _
control resistant weeds.
