{ 70 Situation.
The. state Agricultural College has
been receiving specimens Of wheat
from various points of the state and
Canada and many letters from farm
,6AR asking about rust. All are inter
ested in the rust reports that have
5ecpne current, Prof. Bolley whites,
July "a. to the Fargo Forum and
|Call, and gives the following about
the present conditions OF. the wheat
Crop 10 Cass county which is probably
the same in most parts Of the Red
River valley if not thruout the
state. He says: IS -: 5s.....
4's Aside from the numerous samples
\ which have been examined from
3 Many portions Of the state and Can
ada, I have remained quite constant
d n in the field, by day. about Fargo.
4 Yesterday I spent the entire day in
4 Me wheat, riding thru the fields in
\ al extended circle about Gardner,
i Gfandin and westward and slightly
n3rthward of Hunter. I wish to say
that any statements which claim
that there is an abundance of the
3'stem rust on the heads and necks OF
the grain are at present unreliable.
Il found the wheat there as elsewhere
J showing very heavy stand OF straw
| and that the working power of the
leaves had quite generally been al
most destroyed by the leaf rust (Puc-
cini& rubigovera.)
The outbreak Of the Puccinia
graminis (stem rusty is scattering and
ekenly distributed. l was able to
find few spots of that rust on a few
straws on almost every rod square. of
wheat that,I have been able to ex-
anime. At present this is the
strongest statement that can be
made with regard 70 that rust for
this region of the valley and north
ward. The outbreak of this rust is
not such, as present, as to enable the
ordinary observer to find it in
amounts such as some interested
parties are continually reporting.
Indeed, if no more stem rust should
break out on the wheat than is now
apparent, the general wheat crop
would be quite enormous In this
state. However, the fact that there
Is a rather even sprinkling of this
rust in the fields Of the state from
the South Dakota line to the Can
adam boundary and westward to the
Jim river region makes it possible
that, unless splendid wheat weather
yet prevails, this rust may do gen.
eral harm. BY best wheat weather /
mean cool, clear, windy weather
with the winds in the west and
northwest rather than in the south
and east. for it is the south and east
wind which furnishes the great bulk
,.af rust spores.
The orange leaf rust (Puccinia
rubieo- vera> has now reached the
black stage...almost everywhere, and
it is passing away having done about
as much harm as 1T can do. The
stem of the wheat yet remains
strong. As it has lost most Of its
leaves, it will not mature the grain
as Fast as it should, but il a large
outbreak of Pu0cinia graminis does
not occur the strength OF the stem
is such that good..wheat could be rip
ened everywhere. The only wheat
which is so badly hurt by leaf rust as
to prevent a fair crop is found on the
rich overworked summer fallows.
The stem rust is now making its
first showing of actual postoles or
spots, usually in scattered red lines.
, NOW ouu Ullou IIOAo - q opOS W S"S
low down on the wheat or barley
plants which may be seen to be
turning black, that is the black
spores are beginning 10 form. 1t is
from these first old spots Of stem rust
that the general increase Of rust may
be expected to- occur. the summer
spores or red spores having already
Aeheen scattered. After . spot becomes
black those spores will not germinate
any more this season: that is to say
black spores do not distribute the
,.rust..from plant to%plant.
's The wheat IS generally not quite
in the nilk stage, IS yet / have
been unable to detect any spots q
this stem rust on the heads or necks
Of the straw Of the grain from any
point farther I'll, than the line
running thru Fargo, and such s. ]
have really found are upon the heads
growing here upon the experimental
plots Of the college farm. ss3Ss.
