Controlling Insects, Worms and Rodents 
Good g-ardening 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 marketed in car load lots. Experiments have shown 
that dust is much more quickly and easily applied, in fact, some of the 
larger growers use airplanes for this purpose. These fly low over the 
ground and the blast from the propeller blows the insecticide evenly 
over the crops. 
On page 90 you will And dust guns listed and described and on page 
89 dust insecticides. Select the tyne 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 
thoroughness of application. 
CONTROLLING INSECTS ON 
VINE CROPS 
striped Cucumber Beetles. These in¬ 
sects 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 89. Attach 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 
under the plants. 
Aphis or Plant Pice. These very small insects often cause much 
damage. They increase very ranidly and while at first they remain on 
only a few plants and do not seem to spread, if not destroyed then they 
later 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 up¬ 
ward against the underside of the leaves by means of the curved 
nozzle on the discharge pipe. Stake the infested plants and return the 
next few days and kill any insects that remain. Dust only where aphids 
are found as Aphicide No. 10 kills only by contact. Repeat applica¬ 
tion whenever needed. 
BLACK SQUASH BUGS Because of the extreme difficulty of killing 
the Black Squash Bug, we suggest two dust¬ 
ings with Aphicide No. 15. The first dusting 
wiil 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 live¬ 
stock and poultry. Use 1 lb. Sodium Fluosilicate to each 10 lbs. of bran, 
mix dry thoroughly, add about 1 lb. of molasses or just enpugh 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 evening about the plants 
where the worms are working. 
GROUND SQUIRRELS 
Ground squirrels and other rodents often dig 
up seed after planting. This can be prevented 
by treating the seed with coal tar. First wet 
the seed and then stir in thoroughly at the rate of one teaspooriful of 
coal tar to each peck of seed; dry and plant as usual.
