Controlling Insects, Worms and 
Rodents 
, Good gardening consists not only of proper tillage, irrigation and care 
of the plants but also in combating various pests that will destroy or injure 
the crop. Both dusting and spraying are effective. In the western part of 
the United States, tremendous acreages of vegetables are grown and mar¬ 
keted in car load lots. Experiments have shown that dust is much more 
quickly and easily applied, in fact, some of the larger growers use air¬ 
planes for this purpose. These fly low over the ground and the blast from 
the propeller blows the insecticide evenly over the crops. 
On page 99 you will find dust guns listed and described and on page 
98 dust insecticides. Select the type and size of dust gun suited to your 
requirements. Use Aphicide as a dust, do not mix with water, apply as 
it comes from the package. Adjust the duster properly and blow the 
Aphicide with sufficient force to form a smoky dust that will thoroughly 
coat all parts of the plant. Results obtained depend largely on the thor¬ 
oughness of application. 
CONTROLLING INSECTS ON VINE CROPS 
STRIPED CUCUMBER BEETLES. These insects often appear as soon as 
the plants come up. They are not only very destructive at that time but 
their larva is the small grub or borer which works into the roots of the vines, 
more especially in pumpkins and squashes, but to some extent in melons. 
Dust to kill these Striped Beetles with Aphicide No. 10 or Aphicide 
No. 21—See page 98. Attaph the discharge of your duster to a funnel- 
shaped cone which you can set down quickly over the plants and blow 
one blast of Aphicide, then wait four or five seconds and a second hard 
blast should be sufficient to kill all the beetles on the plant or hiding imder 
the plants. 
APHIS OR PLANT LICE. These very small insects often cause much dam¬ 
age. They increase very rapidly and while at first they remain on only a 
few plants and do not seem to spread, if not destroyed then they loter may 
spread over the whole field within a few days. 
It is the dust and gas covering the insect's body that kills. Start early 
in the season when the aphids first appear. Direct the blast upward against 
the underside of the leaves by means of the curved nozzle on the dis¬ 
charge pipe. Stake the infested plants and return the next few days and 
kill any insects that remain. Dust only where aphids ore found as Aphicide 
No. 10 kills only by contact. Repeat application whenever needed. 
BLACK SQUASH BUGS 
Because of the extreme difficulty of killing the Black Squash Bug, we 
suggest two dustings with Aphicide No. 15. The first dusting will cause the 
bugs to come out from under the clods at the base of the plants. The 
repeat dusting which should follow the other by about one-half minute will 
kill a large percentage of the adult bugs. The young are easily killed by 
one thorough application. 
GRASSHOPPERS AND CUT WORMS 
We have found Sodium Fluosilicate superior to arsenate for use in 
poison bait for killing grasshoppers and cut worms. It kills more quickly 
and is much less dangerous to livestock and poultry. Use 1 lb. Sodium 
Fluosilicate to each 10 lbs. of bran, mix dry thoroughly, add about 1 lb. 
of molasses or just enough to make a crumbly mixture.. A few drops of 
Oil of Anise should be added to the molasses before mixing and sometimes 
a small amount of water. For grasshoppers sow thinly along fence rows 
in the evening or early in the morning. For cut worms scatter in the eve¬ 
ning about the plants where the worms are working. 
GROUND SQUIRRELS 
Ground squirrels and other rodents often dig up seed after planting. 
This con be prevented by treating the seed -with cool tar. First wet the 
seed and then stir in thoroughly at the rate of one teaspoonful of coal tar 
to each peck of seed; dry and plant as usual.
