points should be made. Under-no
circumstances can you reduce the
amount of herbicide by merely
adding a surfactant. Secondly,
surfactants or oils'should never
be used with 2,4-D, ,Embutox,
Kil-mor,. Lasso or. Blades. Oils
and surfactants enhance the
activity of these herbicides to the
point Of damaging the crop.
' Oils need only be applied,,to
weeds that are already growing.
They are usually applied at 1 to
PA gallons per acre. They, are
esjvciaity useful on heavy in-
festations of emerged grasses' or
on weeds that have developed
under dry or • cool conditions.
Under these circumstances,, oils
are superior to surfactants.

Weed Control In Alfalfa •
• The only time to control Weeds'
in alfalfa is in the ' year of
establishment. Since this weed,
control must last the life of the
stand, it must be done right.
„ Embutox is the only herbicide to
"lise"'"ori• alfalfa, at establishment.
This herbicide can 'he applied to
direct seeded alfalfa or alfalfa
seeded. down to grain. •
Embutox should,be applied at a
rate of 12 to 16 oz. of acid per
acre. This means one gallon of
Embutox will cover to 5 acres.
Use the lower rate if the weed
population is low or if the crop is
under stress Conditions; such as
extreme drought or cold. This
herbicide'should be applied in 15
to 20 gallons of water per acre.
„Embutox will control mustard,
only if the Inustard is 1 to 2 inches
high. If at the time of spraying,
mustard is higher than 2", rnix 2
oz. of MCPA 80 (1 oz. acidP'acre
with the' Embutox, Higher rates
of MCA will damage the alfalfa.
The timing of the Embutox
application is critical. It should be
applied When alfalfa has from 1 to
3 trifoliate leaves. Spraying
before or after this date can set
back the alfalfa. For more details •,
see page 32 of the 1978 Guide to
Chemical Weed Control.
Spray'SprIng Grain Burly
There are two main, reasons fqr
spraying grain early. It 'is the
weeds which are growing„during
the early periods of cereal growth
(up to the 5 leaf stage) which have
the greatest effect on cereal yield.
In addition, the ,cereals are most
resistant to herbicides in the 5 to.
6 leaf stage.
The different stages of cereal
leaf developncient are outlined on
page, 4 of the Guide to Chemical
Weed Control. The generally
recommended stage for spraying
is the 2 to 6 leaf stage. Too. often
this task gets left until later with a
resulting-damage to-the crop and
more Competition froin the
weeds.
Oats are less , susceptible to,
injury from MCPA than 2',4-D,
Thus MCPA should be used in
place of 2,4-D for oats or mixed
grain.
There are 2 weeds in some
mixed: 'grain fields in Perth
County that neither 2,4-D nor
MCPA will control. Lady's thumb
and wild buckwheat tend to build
up in fields that have had a
history ef spring grain. For these
harder to kill weeds, the herbicide
to- use is either Kil-more or a'
mixture of Dicamba plus MCPA
or 2,4-D. Kil-mor is a commercial
mix ture of Dicamba, 2, 4-D and
Mecoprop. These herbicide com-
bination§ vvill control the harder
to kill annuals, as well as the
usual • broadleaf weeds such as,
ragweed, mustard, and lamb's
quarter. • - •
Don't Lower Rootworth
lnseetieide Rates
On clay soils, satisfactory corn
rootworm control is only achieved
if 1 lb. of active material (10 lbs,
of 10% product)' is applied per
acre in a 6" band. Some growers
have been using reduCed rates.
Others'•-have....been removing the
insecticide spreader so that the
material dribbles on •in a very
narrow band. A narrow band
protects only part of the root'
system and a reduced rate is„only
partly effective. The control- may
appear adequate 1?uttappearances
can be deceiving. In one 1977
• trial, there was,‘ yield reduction
of over 10 bus. per acre with no,
lodging difference between un-
treated and treated plots.
In South Perth there is a 90%
'chance that an insecticide is
needed„ if ,the field is planted to
corn for the third consecutive
year. In North 'Perth, growers will
have to tnake a decision based on
their exPyrience and particular
circumstances. .
Rootworm insecticides are ex-
tremely poisonous to the
operator. They should be handled
with care and in accordance with
the safety information on the
label. '

and rubber gloves are wise
precautions when handling these
materials.

There has also been a change in
the number ' and structUrb--of
farms in Canada. Relatively
speaking there are now fewer
farmers required to meet the food'
needs of Canadians:
To survive in a commercial

farms have gone out of business,
Those remaining are larger and
