Where this pest is attacking a tree,

This pest does not normally attack
healthy. vigorously growing trees.
When a tree is seen to be infested
with the shot hole, borer it has prob

the pest is. to keep the trees in

The Nematode worm is not an in

small, being hardly as large as the
point of pin. 1t attacks the roots
OF peach%5 trees, making warts OF

serious in light sandy lands than in
clay. IT may kill young trees; and

remedy for this pest except several

called above to the fact that these
should be the only two varieties
used in the peach orchard on lighter
soils.

most serious diseases attacking the

out causes a great loss in the crop
Peaches have been packed in a seem
laS4y sound, condition, and have rot
ted in transit from the point of ship
ment to the eastern markets. On the
fruits this disease forms small, cir
GUAR, brown spots, which rapidly

Drown mass of spores, These dis

OF controlling the disease is to keep
the orchard free from mummies and
rotting fruit. Sprays with self-boil-
ed ;lime-sulphur are also recommend
ed for this disease.

Peach leaf curl is also a very
common disease in Georgia. Most

Die-back is a trouble which has
rapidly become serious in this state,
In recent years quite a number of
reports have been made of trees
dying from an obscure cause. Upon
investigation this cause, was found
to be die-back. This trouble attacks
the twigs, and where trees have be-
come severely weakened by heavy
freezing during the winter, or over
bearing, or serious spring frosts, die
back may attack the trunks and gir-
die them, causing their death. Gut
ting out the dying and injured trees
is the best remedy Where the or
chards are well looked after and the
trees kept in growing and thrifty
.co1ditiCn this disease should not be
serious, except in years following
heavy crops and unusual climatic
disturbances. -... .... 49,
Crown-gall is a serious trouble of
the peach Is we'll as many other
plants. This disease is most often
seen as swelling or tumor-like
growth near the ground line of the
plants, There is no good remedy
for the trouble and nursery trees that
show crowngall should be dis
cardeda Every precaution should be
taken to avoid infected plants, and
when passing from one tree to an.
other at worming time the knives
and scrapers used should be disinr
fected so as to prevent the possible
dissemina ton of the crown-gall from
one plant to another.
Rosette is a physiological trouble,
and no reasons for it's cause or oc-
currence are known. 1t is easy to
tell a rosetted tree by the peculiar
punching of the sickly, green leaves
The tree may be attacked in part,
and when this is. the case it may
live for a year or two, but does not
thrive. AS soon as one knows a
rosetted tree is in the orchard it
should be dug up and DESTROYED. 1t
