local conditions of growth ; so 
the gardener must simply 
watch his own trees, and as 
soon as the leaves are un¬ 
folded, get to work. It may 
not be until May; it may be 
early in April. 
Waiting for the blossoms to 
open and mature and fall, he 
must note the date of the lat¬ 
ter, and three days later make 
a second application. A third 
treatment to catch the larva 
of the codling moth as it is 
entering the newly set fruits 
at their bud end may be neces¬ 
sary when the fruit is set and 
careful observation reveals 
the presence of any more of 
the small worms hanging 
around, waiting for their 
chance to move in. This is 
usually two weeks to a month 
following the second use of 
Arsenate. 
Later in the summer comes 
a second brood of the codling 
moth, resulting in much great¬ 
er damage, if left to its natu¬ 
ral devices, than the first. The' 
spraying table gives the dates 
for getting after this. As the 
worms of this generation en¬ 
ter the fruits usually where 
they touch and rub together, 
impairing the skin, proper

For the small orchard of dwarf fruit trees a portable machine handled by two men 
will be sufficient. Here again the extension nozzle is necessary

Fungi are contested with 
the lime-sulphur spray of 
early February, which cannot 
be used after vegetation is in 
leaf — nor even after the sap 
has begun to run, preparatory 
to the spring awakening. But 
one's troubles are by no means 
at an end with this particular¬ 
ly insidious form of pest 
when the February dosage is 
administered; for increasing 
warmth and the rains of sum¬ 
mer liberate continually and 
favor the germination of the 
infinitesimal spores by which 
all fungous diseases spread. 
As a matter of fact, these 
diseases are more to be dread¬ 
ed in a way than insects, for 
they are practically incurable, 
and their presence is never 
suspected until they have es¬ 
tablished themselves. The 
spores, which are quite as in¬ 
visible as germs, enter the 
leaf or plant tissue and are 
there protected from anything 
which may be applied, so that 
treatment must be made lit¬ 
erally before the trouble ex¬ 
ists. 
In addition to spraying 
with a direct poison for 
codling moth and curculio late

GENERAL SPRAYING TABLE 
Note. — There are hordes of insects not specifically mentioned here, but these are the commonest; and the spraying done against them and as a preventive meas¬ 
ure against fungi will usually accomplish all that the well cultivated and tended garden needs.
