Kills Bugs—Prevents Blights 
All you have to do to keep your farm crops free 
from leaf-chewing insects and fungous diseases is 
this: Mix Pyrox with water and spray. No need to waste time and 
effort mixing Bordeaux and arsenicals. We recommend Pyrox 
because it will not clog the smallest nozzle. It comes out a fine 
mist and covers the foliage completely, sticking to the leaves even 
through the hardest rains. Insects die. Blight is prevented. 
Your farm has a chance to show what it really can do for you. 
One pound of Pyrox makes 5 to 6 gallons of spray. 
Pyrox for Potatoes. Thorough protection against insect in¬ 
juries and plant-diseases is extremely vital. Tops which are full 
of blight-spots and holes cannot produce the greatest possible 
yield. Thorough and frequent spraying with the right material 
and a good machine will keep the vines healthy and will yield 
most excellent returns on the money and time invested. Even 
when insects and diseases are not troublesome, copper sprays 
stimulate the growth of the vines and increase yields. 
5 lbs. $1.75, 10 lbs. $3, 25 lbs. $5, 50 lbs. $7.25, 100 lbs. $12.50, 
300-lb. barrel $30. (Not mailable.) 
Bowker’s Dry Lime Sulphur 
Bowker’s Dry Lime Sulphur is made by a 
special patented process which keeps the product 
in good physical condition, thus insuring its 
going into suspension quickly. Dry Lime 
Sulphur does not have some of the disagreeable 
features of the Liquid and is now generally 
accepted by fruit-growers everywhere. It is 
used either as a dormant spray to kill scale or as 
a summer spray to control fungous diseases such as scab, rot, etc.

Bowker’s Liquid Lime Sulphur (Concentrated)

phur, combined in especially designed apparatus and in quan¬ 
tities so large as to allow plenty of time for storage and settling. 
Thus, the solution which reaches you is cherry-red in color, clear 
and sparkling. It will not crystallize, thicken up in the barrel, 
or clog the finest nozzles. If used according to directions, 
Bowker’s Lime Sulphur will kill every scale that it touches.

Bowker’s Powdered Arsenate of Lead 
Can be used either as a spray or as a dust for 
all external chewing insects. It will not burn or 
injure your crop. It is the fineness of Bowker’s 
Arsenate of Lead that causes it not only to 
spread and to stick better, but to kill better. 
The smaller the particles, the more effective they 
are when taken into the organs of an insect. 
Unlike some brands, Bowker’s mixes easily, stays 
well in suspension, with no trouble from clogged 
nozzles. Sticks to the foliage through heaviest 
rains. In Bowker’s you obtain unusual efficiency 
at no additional cost. 1 / 2 -lb. pkg. 20 cts., 1-lb. pkg. 30 cts., 4-lb.

mailable.) 
Bowker’s Calcide (High-grade 
Calcium Arsenate) 
Excellent for potatoes and truck crops; it is 
cheaper than lead arsenate. Although formerly 
used only in the South to kill the cotton-boll 
weevil, Calcide is now employed in other 
sections to kill such pests as potato bugs, bean 
beetles, and other leaf-chewing insects. Cal¬ 
cide may be applied either wet or dry. 1-lb. 
pkg. 25 cts., 4-lb. pkg. 60 cts., 25-lb. pkg. $2.85, 
four 25-lb. bags $10.50. (Not mailable.) 
Dow’s Magnesium Arsenate 
Experiments show that Dow’s Magnesium 
Arsenate is an effective insecticide for the control 
of the Mexican bean beetle and other chewing 
insects. It proves fully effective without damage 
to tender bean foliage. As a spray, use 6 tea¬ 
spoonfuls to 1 gallon of water. For dusting, use 
1 part Magnesium Arsenate to 3 parts hydrated 
lime. 2-lb. bag 80 cts., 100-lb. drum $22.50.

Bowker’s Powdered Bordeaux Mixture 
A powerful fungicide for the control of 
blights, rusts, and rots on any crops where 
Bordeaux is recommended by the experiment 
stations or other agricultural authorities. Fine, 
light, and fluffy, Bowker’s Bordeaux mixes 
easily and completely. Hence it covers evenly 
and sticks well to the foliage. When bugs or 
worms are present, use Bowker’s Pyrox in 
place of Bordeaux, as Bordeaux contains no 
poison. Bowker’s Powdered Bordeaux Mixture must pass rigid 
tests both as to quality and fineness, etc. 1-lb. carton 30 cts.,

sent parcel post, and must be sent by express or freight. On non-poisonous insecticides, the postpaid prices are given in connection 
with the price.
