For over 50 years Lysol has been used as a personal antiseptic and household disinfectant. Lehn & Fink 
laboratories, by extensive and continuous research, certify the purity of Lysol and seek new uses for the 
product in the above mentioned fields. 
The use of Lysol for the elimination of thrips on gladiolus bulbs is foreign to our own field of research 
and therefore we are unable to furnish verified results from our own laboratories. However, in response 
to many requests for information on this use of Lysol we print the following letter received from 
C. G. Young, Secretary, National Gladiolus Society.

Gentlemen: 
“Late in 1938 I received a bulletin from you dealing with the use of 
Lysol as a dip for the elimination of thrips from gladiolus bulbs at — 
planting time. I used Lysol for my Spring 1939 planting. The amount 
of bulbs treated with Lysol solution was sufficient to plant six acres. 
“T found that Lysol positively eliminated all thrips on the bulbs treated. 
“Also I discovered that this treatment was of great benefit in stimulating 
root growth in dormant bulbs. To my amazement, the dormant bulbs — 
of such notoriously hard starters as Betty Nuthall, etc., showed pro- 
nounced root growth in 3 days following dipping. 
‘Treatment which I recommend is as follows: 
“Mix 4 teaspoonfuls of Lysol to 1 gallon of water. Soak bulbs 
in this solution for 6 hours. 
“For breaking down shells on bulblets, soak in above solution 
for 16 hours or more according to toughness. 
“Bulbs may be dipped and left for as long as three weeks before 
planting. Thus an efficient method of planting may be adopted by 
dipping all bulbs at one time. 
“Dipping solution left for more than one week should be replaced. 
“The total cost of Lysol which I used in dipping bulbs for a six acre 
planting amounted to only $3.20,—an insignificant sum for the value 
received.
