worms which climb up the trunks of
the trees may be caught by applying
strip of cotton batting around the
trunk OF the tree or stem of the plant.
AN outer free strip or layer should
hang down, forming fold, into which
the worms will crawl, and beyond
winch they cannot pass. Sticky paper
may also be applied with the same cf-
feet.
Fungous Diseases = The fungi are
little plants which grow a mycelium
throughout the inner parts of the plant
or Tree, drawing on the vital parts of
the plant in the nourishment of their
own bodies, and often secreting sub
stances that are poisonous to the plant.
AT first they may only retard the
progress of the growth of the plant.
but II unchecked they will spread and
do much damage. The reproduce
I've bodies of fungi, corresponding to
the seed Of higher plants, are called
spores. They are very small dust-like
particles and are capable of germina-
ton under most conditions. and es-
peclally In the presence of moisture.
After fungi have once taken hold Of
a plant they cannot be killed without
destroying the whole plant Their fur
ther spread, however, to other plants
or to other parts of the same plant can
be checked by spraying with Bordeaux
or some spray which will kill the spores
with which it comes in contact. Some
OF the commoner fungus diseases are:
Apple Mildew-Which is character
lied by dwarfing of new shoots, which,
with leaves, remain stunted and COW
cred with a white mildew growth of
fungus. 1t is not preventable, but may
be controlled by spraying with iron
sulphide, Of which there is prepare
ton on the market Also potassium
sulphide one ounce to three gallons of
water, or with a solution of one pound
soda and two pounds sulphur.
Other Mildews-Species of mildew
similar to the apple mildew appear
upon the peach and upon many vege-
tables. Treatment is practically the
same in all cases. In addition to the
Dove mentioned sprays, dry sulphur
will be found effective if sprinkled
over the plants, but in cloudy weather
Bordeaux will be found most effective.
Scab-This fungus appears as scabby
patches on apples and pears. The
patches are Of a bro ,Vn velvety growth,
and render the fruit useless. 1t may
be checked by spraying with Bordeaux,
or mixtures of Bordeaux and arsenate
Of lead, paris green, or spring spray of
lime-sulphur.
Bacterial Diseases
Crown Gall-Appears as large swell
ings on the main trunk and roots of
plants and trees just below the ground
or very close to the surface Of same
1t is caused by a bacterial organism
which ipfects the ground and usually
gains access through injuries made by
a tool or an insect. 1t affects a wide
range of plants, including most of the
small fruits, such as the blackberry,
raspberry, peach, almond, grape, plum,
walnut, etc There is no known means
which will kill the disease. The best
method is to destroy affected parts as
soon as discovered Sometimes they
may be successfully chiseled off of the
roots Of old trees, but in any case
the wounds should be treated with a
disinfectant, such as bluestone one
ounce to one gallon of water, or with
corrosive sublimate, which may be OBJ
tanned in tablets ready to be dissolved
These tablets are bi-chloride of mer-
curry, very poisonous substance, which
should be handled carefully A single
tablet is sufficient to make one pint of
