A SEA OF GLADIOLUS 
INSECTS 
As a rule, Gladiolus are not bothered very much with insects, 
except that late years very minute insects called Thrips have 
been giving some trouble in certain parts of the country. If 
you failed to obtain good bloom last summer, buds drying up, 
etc., the chances are that thrips were to blame. These insects 
are so small that when young they are almost invisible to the 
naked eye, and are very easily overlooked. After your old 
bulbs have been cleaned of the old bulbs and roots, which opera¬ 
tion is best done in late November or early December after 
they have been drying a few weeks, sprinkle Naphthalene 
Flakes over the bulbs at the rate of about 1 oz. (four level 
tablespoonfuls) to 100 bulbs. If in paper bag, fold over top; 
if in tray or box, cover with newspaper; and let stand a month 
or two. Most of the flakes w ill evaporate, and the rest may be 
removed. This kills the thrips which w inter over on the bulbs. 
Do not use naphthalene in the soil. Will mail a box of 
Naphthalene Flakes sufficient to treat 1000 bulbs for 25c. 
This price includes postage to Zone 4. More distant points, 
5c extra. Write for price in quantity.. 
As a spray we recommend “ROTOTOX”. Write to the 
Rototox Co., 815 Yale St., East Williston, N. Y., and they will 
send you printed information regarding Rototox which is very 
complete, with many tips and pointers, and will be of great 
value to any grower of flow r ers. For further information, write
