present an unusual external appearances:
they are shorter and more swollen than
are healthy seeds and are Of dull green
ish drab color and are fre Iuently cracked.
Smut, or, as it is generally called, 'loose
smut" to distinguish 1t from bunt or
hard smut, is not only injurious to wheat,
but to barley. and especially to oats.
AS with bunt, so with loose smut, the dis
ease begins at the bottom and works up
ward. This smut is not restricted, like
bunt, to the seeds alone, but the whole
ear is destroyed.
The above facts, presented by Professor
Fletcher in bulletin issued from the ex-
perimental farm at Ottawa, Canada, have
little practical bearing, unless one can
draw from them something which may
suggest where to look for a remedy This
they do, explains the authority quoted
from. Everything points to the infection
coming from the ground and travelling
upward.
Remedies which have been most sue
cessful are those in which methods have
been adopted to destroy the spores adher-
ing to the seed wheat previous to sowing
by washing or sleeping the grain in some
weak poisonous solution.
A common remedy and one advised by
Professor Fletcher, Director Scovell, Of
the. Kentucky Experiment station, and
Others is q solution of sulphate of copper,
also called bluestone or blue vitriol. Some
advise merely wetting the seed. Others
say to soak the grain. An English author
ity advises: Zone pound of bluestone dis
solved in five quarts of boiling water is
sufficient for a sack of four imperial BUSH
els. The wheat is soaked for ten minutes,
or the ten pints of solution may be poured
over till all is absorbed" A Manitoba
farmer saws the following has proven sue
cessful in his district: Zone pound of sui
phate of copper is dissolved in a pailful of
hot water, which is then sprinkled by one
person over ten bushels of wheat placed
in a wagon box, while some one else keeps
the grain well stirred Should large
amount of smut be detected in grain re-
quired for seed the solution is made
stronger, double the quantity of bluestone
being used" The chief advantage claimed
for this method is that in few hours the
grain is sufficiently dry to sow with the
drill
Mr.. Plumb, while at the New York Ex-
perimental station, used four ounces Of
sulphate of copper in one gallon of water,
and reports that seeds soaked seventeen
and half hours in this solution were
found to produce O. slight amount Of
smut, Soaked forty hours all germs Of
the fungus were killed" It ought to be
told that his experiments were with oats,
in which, from the fact that the seed is
contained inside q comparatively loose
husk, there is much more difficulty in re-
moving or destroying all the smut pores
than is the case with the smooth and
naked grain of wheat.
At the Kentucky station the method of
applying the solution of blue vitriol was
as follows; Ten pounds of blue vitriol
were dissolved in eight gallons of water
and the solution placed in tub. The
seed wheat was put into the solution and
well stirred, care being taken not to put
enough wheat in to come to the top of the
solution. After skimming off floating
wheat and particles the solution was
poured off into q second tub, the wheat
drained and spread on boards to dry. The
solution was reused as often as we had
wheat to treat in this manner. This treat
ment proved entirely successful
