Stations for Grain Grading
The federal department of agricul-
ture in cooperation with the agrlcul-.
tural extension division Of North and
South Dakota and Minnesota plans to
scatter grain grading stations or lab
roatories over these three states this
fall, according to announcement by
Prof. Gordon w. Randlett of the
North Dakota college today. The sta
tions are to be part Of a know
your own grain" campaign. They Will
be merely for the information of the
farmers and grades set by them will
not be official.
Plans are to establish 10 stations in
connection with county agent offices
in each Of the states. The farmers
may send their grain to these stations
for grading any time between Aug. l
and Nov. l.
Two schools will open about the
middle of July to teach the county
agents, or their representatives who
will carry on the grading work, how
to use the equipment which the gov
eminent will allot them. The one IN
Fargo will take care of the 20 pros.
pective graders for Minnesota and
North Dakota while one in Bookings,
S. D., will be for the use of agents
in that state. A representative OF the
bureau Of markets will act as instruc-
tor in each case. The course will last
six days.
A bureau of markets man will also
be allotted to each Of the states dur
ing the three months in which the
stations are operating to supervise
the work.
Farmers will be asked to secure
samples of grain which are as nearly
as possible representative of the gen
eral run of their harvest. If the plan
works out successfully it is hoped to
extend it next year, Mr.. Randlett adj
ded. @.
Ten scattered counties have been
chosen. tentatively, in North Dakota,
but possible changes will occur.
"The county agents in each of the
counties chosen will be equipped with
adequate apparatus and a laboratory
| to which samples Of wheat may be
brought to be tested for dockage, test
weight per measured bushel, such for
eign material as may remain after
the removal Of dockage, which in
cludes other grains, Charley, rye etc.
Kingheads, corn cookie and wild peas
and also wheats Of other classes, also
damaged grain and moisture where it
is problem" according to the Unit
ed States Department Of Agriculture
statement.
Insect Eradication Interests Farmers
Farmers Of the state are taking
greater interest in organized bug
eradication this year than in some
time and inquiries regarding the var
ious kinds of insecticides have been
numerous, according to DR.. RI.
Webster, entomologist at the Agricul-
tural college. Many kinds Of insect
killing mixtures are in use but some
are better fitted than others for diff
ferent plants. ><-
According to DR.. Webster the rela-
tive value Of various arsenical poisons
is determined by the arsenic content,
usually expressed in terms of arsenic
oxide. In addition there are certain
physical and chemical properties
which have an important bearing on
the use of all arsenical insecticides.
The federal insecticide law, as well as
the North Dakota law, sets definite
standards for Paris green and lead
arsenate and these standards are gen
orally followed by most manufacture
ers Of insecticides, DR.. Webster point
ed out.
DIR. Webster has given out the fol-
lowing description Of various poisons
"Paris green usually contains about
IS percent arsenic oxide. 1t must
have not less than so percent. Paris
green acts quickly on insects. It has
two disadvantages, it does not hold up
we'll in suspension in water and it
frequently burns foliage. There is
little danger when applied to potato
foliage.
LEAD arsenate paste usually con-
tains about Is percent arsenic oxide.
It must contain not less than ~ 1/2
percent. The paste is about half wa
ter. Lead arsenate powder contains
about 80 percent oxide. Many brands
of lead arsenate powder are now put
out in an extremely fine physical con-
dition. Lead arsenate acts more
slowly than Paris green upon insects,
but it adheres much better to foliage.
calcium arsenate contains about
| 10 percent arsenic oxide. 1t is some
what less stable than lead. arsenate
and consequently acts more quickly
on insects. It may be used with safe
ty on potato foliage for the Colorado
beetle There is some danger Of
burning more tender foliage"
