This is a MAY-JUNE-JULY (3 Time) Eradicator Treatment— 
OTHERWISE—FORGET IT 
“GUESS-WORK” has been elimniated by Laboratory and Field Work 
Chemical Treatment, Where Crab-Grass Is Prolific Is the Only Practical 
Method of Control. 
Extensive, convincing experimental work by the 
Greens Section of the U. S. Golf Ass’n has determined 
the basis of G&O CRABGRASS KILLER. 
Formula containing Sodium Arsenite or Arsenate 
are too dangerous and poisonous for general use on 
home lawns. 
This KILLER is scientific and practical in its 
action, non-toxic to soil, does not hinder germination 
of grass seed, does not affect the action of fertilizers 
and is definite in its action on Crabgrass, Dandelions, 
Thistle, Plantain, Bind and Chickweed, etc. 
The effect of this KILLER will be noticeable in 
two days after application as the vegetation begins 
to turn grayish. Later the plants look a sickly white, 
then turn brown and curl up. Its killing action on 
CRABGRASS is by the disintegration of the proto- 
plasm, preventing further production of food, CRAB- 
GRASS THEN STARVES TO DEATH. 
INDIVIDUAL CRABGRASS PLANTS—Examine 
the lawn early (May or June in average climates 
north of Richmond, Va.) for their first appearance 
and if present drop a pinch of GkO CRABGRASS 
KILLER right into the center growth and very lightly 
dust the whole plant but not the surrounding good 
grass. 
“THREE TIME TREATMENT” 
(1) EARLY MAY—When CRABGRASS seed- 
ing plants are in the two-leaf stage broadcast two 
(2) Ibs. of G&O CRABGRASS KILLER (just as it 
comes in package) evenly over 100 square feet of 
infested area. This can be done by hand or through 
a kitchen flour sifter or a regular lawn fertilizer 
distributor. 
(2) EARLY JUNE—Apply four (4) Ibs. of 
G&O CRABGRASS KILLER over the same 100 
square feet. 
(3) EARLY JULY—Repeat the same dose as 
recommended for early June and over the same area 
of earth. 
Slight temporary discoloration of the lawn or turf 
will follow each of the foregoing applications but the 
permanent grass will recover and, since G&O CRAB- 
GRASS KILLER contains (and this is most im- 
portant) high inorganic Nitrogen and Phosphoric 
Acid, this recovery will be quicker and treated areas 
will show marked improvement over untreated areas.

Potassium Cyanote 
86% POTASSIUM CYANATE BASE 
The “Selective” Kind. 
Crab Grass (Digitaria Sanguinalis) is the meanest of all lawn 
weeds. An annual grass that creeps and roots at every joint so that 
it finally “mats out” any good lawn where it isn’t controlled. It keeps 
right on propagating by its own reseeding so that one single plant 
produces thousands of seeds in one season. GO-CRAB is a formula- 
tion of Potassium Cyanate, which today is the accepted control of 
Crab Grass. Rather easy to apply in a liquid because it is entirely 
soluble in water and is, for general purposes, at this time considered 
as being non-poisonous to humans and animals, non-volatile and, 
therefore, cannot affect adjacent plant life which is untreated. GO- 
CRAB is selectively and exclusively considered as a Crab Grass 
killer. It will not sterilize the soil and even has some beneficial value 
in soil by reacting with it and causing a release of some of the 
fertilizing elements. 
The big advantage of GO-CRAB is that it does kill the 
Crab Grass without hurting the other lawn grasses. 
A temporary set-back of these other lawn grasses, though slight 
discoloration is naturally noticeable for a few days, but within 10-14 
days the good grass recovers a normal appearance, including the 
clover, and the Crab Grass is wiped out. Feeding and reseeding lawns 
is certainly recommended after the destruction of Crab Grass so 
that the bare spots fill in and reproduce.
