Although there Is no remedy for the
Hessian fly when once II takes possess
sion OF crop of wheat. great deal
can be done toward keeping the fly out
of the wheat.
Since the Hessian fly Is the most de-
structive insect enemy of wheat In the
United States, control measures pay.
There have been at least seven general
outbreaks east of TIE Mississippi river
in the past 81 years, and another is re-
garded as imminent by specialists of
the bureau of entomology. The nver-
age annual damage to wheat through
out the United States from this insect
is estimated Mt S50.OOO,OOO.
How to Stop Losses
The means of preventing loss, as
summarized by the department, are
these:
Practice crop rotation. Do not SOW
wheat on stubble if it is possible to
avoid doing so.
Plow under all infested stubble,
where practicable, soon after harvest
after it has been determined that the
crop will be failure.
Destroy all volunteer wheat by har-
rowing. disking. plowing, or some other
method.
Plow all land to be sown to wheat
as early and deeply as existing condi-
tIons permit. and prepare thoroughly
pulverized and compacted seed bed.
Conserve moisture against period
Of drought at seeding time.
Use good seed.
Fertilize.
Sow wheat during the fiy-free period
as advised by your farm adviser or
state experiment station.
Adhere to these practices every year
whether the fly is abundant or scarce
They will Eelp to keep 1t scarce.
Community cooperation Is essential
II success is to be attained. because one
infested field may furnish enough t.5.s
to damage the wheat for several miles
around.
When to Sow Wheat.
Sowing wheat during the fy-free
period means moderately late sowing.
Experiments conducted over great
many years have shown that. in most To-
calities, the safe date for sowing wheat
to escape Hessian fly Injury usually
comedies with the proper time for SOW
ing In order to obtain the largest
yields independently of Hessian fly in
jury. These dates lave been deter
mined for certain localities as follows:
In northern Michigan. soon after the
1st of September.
In southern Michigan and northern
Ohio, about September 20.
In southern Ohio. after the first
week in October.
In extreme northern Illinois the safe
period usually occurs from September
81 to IS.
In central Illinois a1d Indiana. from
September 2l to 80.
In extreme southern Illinois, from
September 30 to October 8.
In central Kentucky, from October
to 10.
In central Tennessee from October
10 TO %.
In Georgia and South Carolina, from
October % to November 25.
In northeastern Kansas the safe pc
riod ia from October to 10.
In east-central Kansas, usually from
October to 20.
In aytreme southern Kansas and
northern Oklahoma wheat should not
be sown until the second week In Oc-
tober.
This is true also of Virginia near sea
level.
October-sow1 wheat always enjoys
the greatest freedom from the fly in
Maryland. except In the mountainous
regions where earlier planting Is nee
essary.
In southeastern Pennsylvania the
safe period is during the last week OF
September, aad practically the same
corresponding delay In wheat sowing
in tie fall should be followed to the
southwark.
These dates are only approximate,
and serve to show In general way
about H.. ti.ne when the fall brood OF
