Insect and Disease 
Control 
Insects are commonly 
divided into groups-the 
POISON Biting and the sucking.

(¢ > with biting mouth parts 
Pe Se with which they chew off

plant tissue. Whenever

ck OF ten in the leaves, or the 
“4° leaves disappearing as 
O19 /778eCT the insect eid: he can 
be sure that it is the biting type of insect that is doing the 
damage. To control it a poison such as Arsenate of Lead is 
dusted or sprayed onto the leaf surface, so that the insect, 
as he continues his feeding, will devour the poison along 
with the plant tissue. 
Sucking insects, on the other hand, do not devour any 
plant tissue but by means of an elongated mouth part, or 
proboscis, pierce the leaf or stem and suck out the juices 
from the inside in much the same manner that the mosquito 
feeds. Arsenate of Lead or similar stomach poisons have no 
effect upon the sucking type. They must be controlled by 
using a spray or dusting material which kills by coming 
in contact with the body. Some form of tobacco spray (Nic- 
otine Sulphate) is generally used. 
Of the various groups of plant diseases only one, the 
Fungus Disease, is effectively controlled directly by spray- 
ing. This type of disease spreads by means of a small single- 
celled part called a spore. The spores float through the air, 
light on the host plant and under favorable conditions of 
temperature and moisture ‘‘spout,’’ sending out a min- 
ute ‘‘shoot’’ which grows along the surface of the plant, 
until it finds an opening through which it gains admission. 
Once inside of the _ plant, 
sprays do not effect it, but 
jit may be held in check by a 
coating on the plant surface 
of a poison such as Lime 
Sulphur, which can kill the 
shoot before it gets into the 
plant tissue.

See complete spray program on pages 20 and 23. 
SCALE INSECTS. On deciduous woody plants use dormant 
Lime Sulphur spray (See page 20)). On evergreens (not- 
ably for Pine Leaf Scale) spray Lime Sulphur, 1 part to 
25 parts of water, just before the buds break inj the spring. 
RED SPIDER. Dust with a fine dusting sulphur at the hot- 
test part of warm, quiet days. 
LEAF HOPPERS. A thorough spraying of Bordeaux mixture 
will usually eliminate them within two or three days 
after its application.

Spray (or dust) with Arse- 

CUTWORMS. Use poison bran mash consisting 
of bran, 1 quart; Paris Green, 1 teaspoonful; 
molasses, % cup; and enough water to moist- 
en. A small quantity of this mixture should be 
placed near each plant, or it may be broad- 
cast around the plants. Apply late in the even- 
ing after sundown. 
CUCUMBER BEETLE. Dust the plants with a 
mixture of one pound of calcium arsenate to 
20 Ibs. of gypsum or land plaster. Apply as 
soon as the plants are up and dust often 
enough to keep the leaves covered. 
GRUBWORMS, NIGHT CRAWLERS and OTHER 
EARTH WORMS. Sprinkle solution of 2 oz. Mer- 
curic Chloride to 50 gallons of water on 1000 
square feet of space—or scatter 5 lbs. of Ar- 
senate of Lead mixed in 25 lbs. of dry carrier 
(as sand). Water well. 
ANTS. Squirt Carbon Bisulphide into the holes 
with an oil can. Highly explosive. Keep away 
from fire. Use plenty! 
BROWN PACH ON LAWN. Dust with certain 
chemicals—better ask us. 
OTHER TROUBLES 
CRAB. GRASS. The worst lawn pest. Heavy fer- 
tilization of lawn in early spring and late 
August is probably the best starting point. 
Raking and cutting (with grass cutter on) 
plus hand picking also helpful. Leave grass 
as long as possible through June and early 
July. 
MICE. In late fall mound dirt up around roses, 
fruit trees, Bolleana Poplars and other poten- 
tial “victims,” or wrap with fine wire screen. 
Poisoned grain in Suitable weather-proof and 
bird-proof “stations” is very effective and 
largely used by extensive orchardists. 
RABBITS. Shrubs, trees and evergreens may be 
protected from rabbits by wrapping with pa- 
per, burlap or wire screen. Shooting, trapping 
and snaring are helpful in eliminating rabbits, 
but we have obtained our surest and cheap- 
est control by gassing them in their burrows 
with Cyanogas. 
NOTE! MOST OF THE MATERIALS SUGGESTED 
ABOVE ARE DEADLY POISONOUS AND GREAT 
CARE SHOULD ATTEND THEIR HANDLING 
AND STORAGE.

In pest control “let us spray” is our motto. We are splendidly equipped with 
high pressure power sprayers to furnish adequate tree protection in the Min- 
netonka district. Let us talk your needs over with you early so that you can 
avoid the damage to trees and inconvenience to yourself from such cantankerous 
cankerworm infestations as we have had the past few years.
