| INJURIOUS INSECTS.
The following article compiled by DR..
George +. Payne, state chemist, and
published i'll the last fertilizer bulletin,
should have wide circulation, and be
carefully read, by all the farmers in the
state.
They may be divided into two divis-
ions or classes according to their man
ner of feeding.
l. Biting or chewing insects include
all those perfect or imperfect forms
which bite and consume substances
upon which they feed.
2. Sucking or piercing insects include
all OF those perfect or imperfect forms
which pierce their food substances with
beak and suck out the sap or Juice
from beneath the surface.
Insects that belong to the first divis-
ion and like the potato bug, eat the
leaves, may be easily destroyed by Paris
green or London purple applied to the
food substance either in powder or a
liquid. If on the other hand like squash
bugs, plant lice, and other insects be.
longing to the second division, they
suck the sap from the plant causing it
to wlther and die, poison will have lit
tie effect on them because we cannot
apply 1t to the inside of the plant where
they get their food. Most of this class
OF insects may, however, be easily de.
stroyed with remedies like Insect Pow
der or Hellebore. These powders kill
by contract when applied to the insects
themselves. Such insects have breath
ing holes distributed over their bodies.
1t is usually claimed that powdered
substances should be applied in the
morning when the plants are wet with
dew; while this may have its adyanta-
ges 1t is not alwayr necessary, as it may
in most cases be applied at any time in
the day, but never when the wind is
blowing hard
In using Paris green or London pur-
pie, or Hellebore, the following rules
shobld be observed:
The poison should be kept in safe
place, and plainly labelled poison"
Do not distribute the poison with the
hands
Always keep to the windward side of
the plants or trees when applying the
powder or liquid.
DO not use them upon leaves or fruits
that are soon to be erten Give the
rains chance to wash it off.
Never apply it to frrfit trees when in
bloom, as the poison will kill the bees
SO necessary to the formation of the per-
feet fruit.
Paris green and London purple may
be diluted with a cheap quality of wheat
flour, which is probably the best sub.
stance for the purpose on account of its
adhering to the plants and being more
readily eaten than other substances.
Land plaster is also recommended, or a
mixture of half and half. so pounds
each of flour and plaster to pound of
poison is about the proportion when
used in dry form on potato plants,
| fruit trees, etc. To use i'll q small way
mix about = once poison with one quart
OF flour or plaster. 1t can be applied to
great advantage by the use of powder
gun. ]
When used with water the following
| proportions are recommended
For potatoes, one pound poison paris
green or London purple) to 100 gallons
of water.
For apple trees, one pound poison to
$50 gallons of water
For pear, plum, and cherry one pound
poison to 200 gallons of water.
For peach, one pound poison to 300
gallons of water.
The Paris green or London purple
should be mixed into smooth paste be-
fore adding the water. The mixture
must be.applied in fine spray so as not
to deluge the roliege, and should be well
stirred while being used.
While hellebore is vegetable SUBJ
stance which will kill certain insects
both by poisoning and contoct, and il
used successfully against currant worms,
rose and cherry slugs. It's principa.
value, however, is that of destroying
currant worms.
To use whale oil soap, dissolve one.
half a pound..of soap in about one quart
OF water, then add from four to FIVE gall
Ions of cold water and apply every 9th.
er day with garden syringe or an ordi-
nary watering pot.
For the trunks and branches of trees
use thicker and apply with a brush.
