NAPTHALENE FLAKES 
If thrips were present in your gladiolus 
it is advisable to use naptlialene flakes 
among the bulbs. After the bulbs are 
thoroughly dried, and preferably after 
they have ])een cleaned and are ready 
for storage, probably in November, use 
at least 1 oz. to 100 large bulbs, or equiv¬ 
alent bulk of smaller ones. Cover the 
bulbs, but not too tightly as there is al¬ 
ways some evaporation. Napthalene 
flakes do not harm the ])ulhs as long as 
they are entirely dormant. 
MERCURIC CHLORIDE 
(Corrosive Sublimate or Bichloride 
of IMercury) 
The indispensable and universally ac¬ 
cepted treatment of gladiolus for disease 
cure and prevention is the Mercuric 
Chloride treatment. This treatment kills 
insects, such as thrips, and destroys their 
eggs, as well as the spores of fungi. 
Soak the bulbs over night from 8 to 
12 hours, in a solution of 1 oz. Mercuric 
Chloride to 7 gallons water. Dissolve 
the Mercuric Chloride powder in 1 qt. of 
hot water and mix it with the 7 gals, of 
water, which should be above 60 degrees.
