That "Old Devil" CRABGRASS 
_ For use ANYTIME during growing season 
BEST — SUREST and the most ECONOMICAL 
Selective 
GO-CRAB 
86% POTASSIUM CYANATE BASE 
The big advantage of GO-CRAB is that it does kill the Crab Grass without hurting the other lawn erases. 
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 fer- 
tilizing elements. 
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 danger- 
UGremasesia, ous and poisonous for 
Sed general use on home 
SODIUM CHLORATE BASE ©¥"* 
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, Dande- 
lions, 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 protoplasm, pre- 
venting further production of food, CRABGRASS 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. 
BUT “WHAT THINKEST 
A temporary set-back of these other lawn grasses, though slight 
discoloration is naturally noticeable fot 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.

THIS FORMULA IS USED IN THE SPRING 
MAY-JUNE-JULY (3 Time) Eradicator Treatment— 
“THREE TIME TREATMENT” 
(1) EARLY MAY—When CRABGRASS seeding plants are in 
the two-leaf stage broadcast two (2) lbs. of GeO 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. Ms r 
(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 GO CRABGRASS KILLER contains (and this is most 
important) high inorganic Nitrogen and Phosphoric Acid, this re- 
covery will be quicker and treated areas will show marked improve- 
ment over untreated areas.
