WORMS AND OTHER UNDERGROUND 
PESTS 
Combated With Preventive Measures 
P ESTS that operate underground are hard to cope 
with. Preventive measures are by far the best. 
Have the ground so well prepared and of such 
nourishing character that the plants by a brisk, vigor¬ 
ous growth will survive ordinary attacks. Proper 
rotation of crops is also essential. Lime should be 
applied at least every third year. Plants particularly 
subject to attack should have soft Scotch soot scat¬ 
tered in the seed drill. Tobacco dust may also be 
used, but it soon loses its strength. Carbon bisulphide 
is very good after the plants have been attacked. It is 
applied by making holes with a stick 4 to 6 from 
the plants and pouring a teaspoonful of the liquid 
in each. 
Poisoned bran mash is an¬

Identification 
A parasite that causes 
cabbage roots to lose 
fiber. 
A grayish green worm 
about YP' long that 
operates at surface 
of ground. 
A very tiny insect, 
causing grape roots 
to club up like cab¬ 
bage. 
A tiny white maggot 
that feeds on the 
roots and bulbs of 
onions, leeks, etc. 
A parasite that de¬ 
stroys the skin on 
potatoes, causing 
wounds known as 
scabs. 
Parasites of various 
kinds that attack 
root crops of differ¬ 
ent types. 
Small white grubs 
that attack the roots 
of cabbage, turnips, 
radishes, etc. 
Effect on Plants 
The plants wilt down 
in daytime. Club 
root is certain 
death. 
Usually severs com¬ 
pletely any plant it 
attacks. 
The root fiber is de- 
s t r o y e d and the 
plant eventually 
dies. 
The roots are de¬ 
stroyed and the en¬ 
tire bulb eaten out. 
Lessens the crop and 
lowers the quality 
of the tubers. 
Entire crops are some¬ 
times lost by at¬ 
tacks. 
If these maggots are 
present in any 
uantity they will 
estroy crops. 
Causes 
Improper rotation of 
crops and unhealthy 
soil conditon. 
Permitting the garden 
to get weedy in fall 
provides places for 
eggs. 
Poor soil, lack of 
drainage, bad grow¬ 
ing conditons. 
Plants that are grow¬ 
ing poorly are sure 
to be attacked. 
The parasite is trans¬ 
ferred from one 
field to another by 
seed potatoes. 
Usually the result of 
bad growing condi¬ 
tions. 
Poorly drained soil, 
improper rotation 
and impoverished 
soil. 
Plants Attacked 
Principally cabbage 
and cauliflower. 
Soft plants of any 
kind: cabbage, 
beans, geraniums, 
coleus, etc. 
Most troublesome to 
imported varieties 
of grapes. 
All members of the 
onion family. 
A potato disease only. 
Turnips of all types, 
radishes, carrots, 
beets, etc. 
Cabbage, cauliflower, 
Brussels sprouts, 
radishes, turnips, 
parsley, etc. 
Preventatives 
Proper liming and 
working of the 
ground in fall. Crop 
rotation. 
Placing paper collars 
or poisoned bran 
mash around the 
plants. 
Good rich soil with 
proper drainage and 
cultivation. 
Spraying frequently 
with repellants 
when the seedlings 
appear will prevent 
the moth from de¬ 
positing her eggs. 
Proper rotation, plen¬ 
ty of plant food and 
constant cultivation. 
Plenty of lime; soot 
in the drill with the 
seed; good cultiva¬ 
tion. 
Using plenty of lime 
or soot on the in¬ 
fected ground. 
Cure, if Any 
No remedy. Infected 
plants should be 
u 1 1 e d up and 
urned. 
Worms can be found 
at night with a lan¬ 
tern. Work soil 
with fingers in day¬ 
time. 
Destroy infected 
plants. Protect ad¬ 
joining plants by in¬ 
jecting carbon bi- 
sulphide in the 
ground. 
Soot and lime sown 
along the row just 
as seedlings appear. 
Liquid insecticides 
sprayed on the 
ground. 
Dipping the seed be¬ 
fore planting in a 
solution of forma¬ 
line. 
Usually too late to 
correct the trouble 
by the time we are 
aware of it. Pre¬ 
ventative measures 
best. 
Injecting carbon bi¬ 
sulphide in ground 
at base of plant. 
Sprinkling ground 
with very hot 
water. 
BEETLES THAT BORE 
Destroyed by Contact Sprays 
T HESE beetles or bugs bore into 
the foliage or flowers. While 
classed as eaters, they consume 
so little actual surface that could be 
covered with a poison spray that it 
would be useless to employ this means 
to destroy them. Consequently they 
must be attacked with contact sprays 
exactly the same as are used for aphis. 
Because of their hard bodies they are 
The rose bug is best controlled 
by hand picking 
much more difficult to kill than the 
latter pests. 
The rose bug must be hand picked. 
Tapping the flowers over a pail con¬ 
taining a little kerosene will also prove 
effectual. Rose bugs often attack in 
swarms, and when they become really 
plentiful they are apt to attack grape 
foliage as well as other things. Under 
these circumstances many of them can 
be poisoned. The curculio is a hard 
pest to destroy, and where it infests 
orchards it does much damage. Con¬ 
stant spraying with a good insecticide 
will help.
