"Dusting as a mean Of destroying
both insect and disease pests of plants
is coming to the 'front.' said A. F. Yea.
ger, horticulturist at the North Dakota
Agricultural College this week in
speaking of care of potato fields at
this time of the year.
"a standard mixture used in the
liquid form for the the control of both
diseases and insects is bordeaux mix.
ture and arsenate of lead. The Dor.
deaux mixture serves to destroy the
potato wilt and all leaf diseases and
to drive away the flea beetles which
are carriers Of MOSAIC diseases" said
Mr.. Yeager. "The arsenate of lead
poisons the ordinary potato beetle and
all other insects which bite the leaves"
When used as dust It is better to
put in copper lime dust instead Of the
bordeaux mixture, with the arsenate
Of lead, said Mr.. Yeager. Dusting as
means of insect control is not new
practice nor have we been without
good busting machinery both for or.
chard and vegetable crops. But dust.

ber beetle. Either arsenate of lead,
paris green, or calcium arsenate can
be used as an insectfcide in busting OF,
liquid preparations. Paris green is the
quicker acting poison, calcium arsen.
ate acts slower, and arsenate of lead
acts slower still. The quicker acting
poison will show results sooner but is
more liable to burn the leaves.
On small patches such as back yard
gardens the most economical method
of applying dust preparations is place
them in flour sack and shake the dust
on the plants when the air is still.
Striped cucumber beetles do not
like dust and will be driven away from
the garden by the application of any
Kind of dust such as wood or coal ashes
or even common road dust. Dust such
as often troubles Ford drivers, will
cause these little pests so much dis
comfort that they will leave the garden
as fast as they can," says A. f. Yeager.
horticulturist at the North Dakota
Agricultural College.
"The dust does not kill the beetles
and as soon as little shower comes
they will come back to feed upon the
plants again and the dust treatment
must be, renewed" said Mr.. Yeager.
