The herbicide-treated surface

Since heavy disks may cut from
six to eight inches deep, the her
bicide was incorporated in a spiked
pattern from six to eight inches
Annual grass control was poor
but nutsedge control was very
good The herbicide was too
uneven and too deep for good
annual grass control, but her
bicides which diffuse through the
soil will get the deep-germmatmg

as Dual or Lasso which are not
volatile, probably would not work
with this kind of incorporation

inches deep Because the soil
surface was very rough following a
heavy disking as compared to a
olowed and disked surface, the
herbicide was incorporated much
deeper.
Still, annual weed control was
excellent and nutsedge control was
poor Apparently the herbicide was
till not incorporated deep enough
to get the nutsedge

grass control was obtained when
the heavy disk was allowed to
penetrate to about four inches deep
rather than allowing it to go to its
full dept
However this resulted in less
vellow nutsedge control
What’s the ‘best’ system 1 '
The best tool for incorporating
herbicides where both shallow
germinating annual grasses and
deep-germinating nutsedge are a
problem was the cultimulcher on
plowed ground, smoothed by
tandem disking
The tandem disk was almost
equal to the cultimulcher on
plowed ground, and was the best
tool for incorporation when used
after a chisel plow or heavy disk

Although annual grass control
was not as good as that obtained
with a Roterra and nutsedge
control was not as good as with a
heavv disk, the tandem disk was
the one incorporation tool that did
a reasonably good job on both
nutsedge and annual grasses,
regardless of the primary tillage
tool used
Where only shallow-germinating
annual grasses are a problem, the
Roterra was equal to the tandem
disk on smoothed, plowed ground
The Roterra was best following a
chisel plow or heavy disk
When only nutsedge was a
problem incorporation with a
heav\ disk was the best The heavy
disk should be allowed to penetrate
as deep as it will go
One additional thought that
might improve the weed control
from a PPI herbicide is the amount
of herbicide used per acre
If incorporating at a shallow
depth for annual weed control, a
lower rate may be used since the
herbicide is left in a concentrated
layer close to the soil surface
If the herbicide must be in
corporated deeplv for nutsedge or

rhizome johnsongrass cotnrol, the
highest recommended rates should
probably be used since the her
bicide is going to be mixed through
more soil and the concentration
will be diluted
When deep incorporation is
necessary to control nutsedge and
johnsongrass, but shallow in
corporation is also needed for
annual weed control, it may be
possible to incorporate the her
bicide at two depths This can be
accomplished if the sprayer is
mounted on the disk
heavy disk, farmers can disk twice
' and apply one-half of the herbicide
each trip The herbicide will be
applied to a rough soil surface and
incorporated deeper on the first
trip
the second application will be
made to a much smoother surface
and incorporated more shallowly
The same result may be ac
complished by overlapping the
disk half way on successive trips
across the field
The disking depth does not need
to be changed between trips to get
this herbicide layering effect
