From the time the seeds Of garden
crops are put into the ground until the
crops are gathered, diseases and In
sects that must be fought may ap-
pear. Vegetable troubles are due to
numerous causes, including unfavor-
able soil conditions, too wet or too
dry, too rich or too poor, lack Of humus
or Of lime, whether unsuited to some
crops, careless use Of fertilizers, or at
tacks of fungi or other parasites. The
adoption of the best horticultural prac-
sice-crop rotation, the careful APP
plicatlon Of fertilizers suited to each
crop, adequate cultivation, the plant
ing of all crops in their proper season
lis important for the successful grow
ing Of garden crops.
Special Treatment Required.
The control of diseases due to fungi,
bacteria, and other enemies requires
special additional treatment, as does
the damage caused by insects. A new
bulletin has just been issued by the
United States Department Of Agricul-
ture, as Farmers Bulletin 1871, Dis
eases and Insects Of Garden Vege-
tables, the purpose Of which is to
present briefly control measures for the
most important insects and fungous
and bacterial diseases Of the home-gar-
den vegetable crops.
The use of disease-free seed and
~1Iop+c eorc +bo o41tho,. ~ +bo hy111o+ir
is fundamental to all insect and dis
ease control A modified application
of the principle of crop rotation can
be made even in the home garden by
moving the rows Of each vegetable to
another place each year. Many dis
eases and insects live over winter in the
soil and will appear on the plants
again next season If they are in the
same soil. Furthermore, since many
of the pests of closely related crops
are the same, such vegetables should
not be planted in succession. Vine
crops, such as cucumbers, melons,
etc, should not follow one another, nor
should cabbage, caulifiower, or related
crops follow one another.
Numerous important diseases are
carried in or on the seed and cannot
be controlled by seed treatment, such
as bean anthracnose, pea pod-spot, and
potato leaf-roll and mosaic. 1t is there
fore essential to secure the most dis
-ease-free seed obtainable.
Methods of Control.
In presenting the methods Of con-
trolling insects and diseases the bull
letin discusses them under two head
irgs, Treatment" and prevention"
Under Treatment" are discussed the
methods of control which may be ap-
piled after the disease or insects have
appeared in the garden, such as the
use of poisoned bait for cutworms, che
hand picking Of insects, and spraying
for disease and insect control. Undel.
prevention" are ircluded all measures
of control applied prior to disease or
insect appearance which will tend to
hinder or stop the development Of dis
eases and insects or prevent their over
wintering to attack the next seasons
crops, such as planting disease-resist-
ant, disease-free, and weevil-free seed,
treatment Of seed to kill insects and
diseases, or planting crops on parts Of
the garden free from the pests.
