VISITORS DRIVING THROUGH THE GLAD FIELDS 
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 will evaporate, and the rest may be 
removed. This kills the thrips which winter 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 flowers. 
Rototox employs rotenone as its base in combination with 
the other toxic and protective elements of derris root, and is 
many times more effective than nicotine or lead arsenate. 
Rototox acts in three ways—as a contact killer, a stomach 
poison, and a repellant. It will not clog the sprayer and will 
not discolor blossoms or foliage if used correctly. 
In addition to glads, use it on delphiniums for mite control 
and on dahlias for leaf hopper and corn borer and for a general 
spray on all your flowers and vegetables. 
To save you time in ordering we list Rototox prices here: 
1 oz. 35c; 8 oz. (makes 12 to 24 gals, of spray) $1.00; 1 pt. 
$1.75; 1 qt. $3.00; 3^ gal. $5.00; 1 gal. $10.00. All postpaid.
