Sprays For Garden Insects 
(Continued from page 168) 
dent besides being the standard insecti¬ 
cide. The use of kerosene itself ap¬ 
plied at the rate of one ounce to IS 
square feet of water surface, has proved 
a very effective means of controlling 
the mosquito. An insecticide for the 
control of scale insects can be made by 
heating two ounces of soap in a pint of 
water. When dissolved one quart of 
petroleum is added to the hot solution 
and the whole shaken or churned until 
a perfect emulsion is formed. This is 
then diluted with 9 parts of water. For 
ordinary insects the solution is diluted 
with IS parts of water, and for the 
control of soft bodied plant lice this 
spray is diluted with 20 parts of water. 
The application of the kerosene, or in 
fact of any oil, should be just sufficient 
to wet the plant without allowing it 
to run down and collect in puddles. 
Unless this precaution is taken the plant 
may be seriously injured. 
The harm done by masticating in¬ 
sects in the various stages of their life 
cycle to the plant is far more noticeable 
and often very injurious so that they 
have to be controlled by food poisons. 
The most important of these are the 
arsenical compounds which have sup¬ 
planted, practically, all other sub¬ 
stances. Of these, arsenate of lead and 
arsenite of lime are much safer to use 
than the older Paris green. The former 
is prepared by com¬ 
bining three parts of 
crystallized arsenate of 
soda with seven parts 
of crystallized acetate 
of lead in water. These 
substances, when pul¬ 
verized, readily unite 
and form a white pre¬ 
cipitate of lead arsenate 
which is kept more 
easily in suspension in 
water than any other 
poison. It can be used 
without injury to the 
foliage of even the 
most delicate plant at a strength vary¬ 
ing from one to five ounces of this 
combined weight to two gallons of 
water. 
The arsenite of lime is prepared by 
first boiling one ounce of white arsenic 
with four ounces of sodium carbonate 
in half a pint of water for 20 minutes 
or until dissolved. One ounce of this 
stock solution, which will keep in¬ 
definitely, is poured into 8 J /2 gallons 
of water in which has been previously 
mixed three ounces of freshly slaked 
lime. This arsenate of lime can be used 
for ordinary spraying. The greatest 
care should always be exercised in pre¬ 
paring these arsenical stock solutions 
and afterwards in keeping them plainly 
labeled to prevent their being mistaken 
for some other substance. 
The fumigation of growing stock, 
although not exactly rare, is more or 
less restricted to certain regions and to 
special cases. In spite of the fact that 
it is the most thorough method for the 
control of scales, thrips, aphids, etc., it 
has not been generally adopted, first 
because of the deadly poisonous nature 
of the hydrocanic acid gas, secondly 
because of its disastrous effects on tender 
plants if improperly used? and thirdly 
because of its cumbersome procedure 
requiring considerable skili. Then, too, 
it occasionally happens that some plants 
appear to have been 
injured although the 
correct dosage was 
given and the condi¬ 
tions were favorable 
for application. Prob¬ 
ably the most impor¬ 
tant use of this gas is 
as a means of control¬ 
ling insect pests in 
greenhouses and cold 
frames as well as fu¬ 
migating nursery stock 
about to be sent to 
other localities.
