stores and can be applied, full strength, to the bulbs 
by means of a dust-gun or, a small amount of the 
material may be placed in a tough paper bag along 
with a dozen or more bulbs and the bag shaken or 
rolled around (with the top held closed) until the 
bulbs are covered. When Arasan dust is used it 1s 
not necessary to plant the bulbs immediately. 
(Caution: When using Arasan or any other chem- 
ical dust care should be taken to prevent the ma- 
terial from getting into the eyes; some of these 
chemicals are very irritating ‘to delicate tissues.) 
THRIPS CONTROL: The worst-insect enemy ot 
the gladiolus is thrip. These minute insects cause 
damage to the foliage, discolor the blooms and cause 
blasting of the buds (failure to open). Even thougn 
all of your bulbs may have been dusted with DDT 
and dipped, thrips may find their way from nearby 
plantings and multiply very rapidly. It is a good 
plan to locate and inspect all gladiolus plantings in 
your neighborhood. 
Start dusting your plantings with 5% DDT dust as 
soon as the foliage is about 6 inches high and repeat 
every ten days to two weeks throughout the entire 
season. Get your neighboring glad growers to do 
the same. More frequent applications must be made 
if thrip damage is noted. Apply the dust as a cloud 
about the plants rather than individual plants. Even, 
better results have also been obtained from the 
wettable powder or emulsions. For spraying use | 
oz. of 50% wettable DDT to 3 gallons of water. 
Past results from various parts of the United States 
indicated that DDT applied either as a spray or 
dust was much more effective than tarter emetic- 
sugar sprays for thrip control. (Before using DDT 
emulsion be sure it is recommended for use on plants 
then use the strength recommended by the manu- 
facturer.) 
We can supply DDT dust in 5 lb. bags for $1.20 
postpaid.
