G ladiclus Care and Culture 
DDT. We are finding DDT very effective as a thrip control. Either dust or spray is effective. We have been 
using 5% dust at the rate of 30 lbs. per acre each time over. We use a power machine, but a hand duster that 
will make a dust fog around the plants will be just as good. But remember to kill the thrip, the dust must touch the 
insect and as they are normally inside the sheath, one dusting or two will not clean them out. Three to five applica- 
tions is usually necessary. The Glads can be dusted even when in bloom without harm to the bloom. The 5% dust 
comes ready mixed and can be used without other preparation. 
Many prefer a liquid spray and we have 50% Wettable Powder DDT which should be diluted with water to 
about 5% DDT strength. 14% Ibs. to 100 gallons of water is about right or about 4 level teaspoons to 3 gallons of 
water. 
The best part of a DDT spray or dust is that there is no danger in using too much or too strong a concentra- 
tion. The active ingredient is harmless to anything but insects. A toxic condition may develop from inhaling too 
much of the dust or spray, but it has no permanent effects. Ordinary care is usually sufficient to insure no damage 
to the person making the application. 
LEXONE or GAMMEXANE: A new treatment for the elimination of wire worms in the soil is now 
on sale. This is Lexone or Gammexane, the trade names for practically the same materials as put out by two separate 
firms. The material has a very bad odor and must be handled carefully for that reason. This can be mixed with 
DDT dust and applied to plants as usual at the rate of 12 lbs. per acre or sprayed directly on the ground and cul- 
tivated in at the rate of 5 lbs. to 100 gallons of water. This is new and we will elahorate on this treatment as soon 
as we get more information. 
WHEN CUTTING: Flower spikes, a small knife blade slid down the stem on each side between the stalks 
and the leaves and cutting across at the bottom, will enable you to leave a safe four to six leaves and also a good 
stem on the spike. Spikes are best cut in the morning when one or two blooms are open. 
DIGGING: Bulbs can be dug 30 days after the flower is gone, or before freezing weather sets in. Don’t 
wait until the foliage turns brown. The tops. should be cut off at once as close to the bulb as possible, pruning 
shears doing this very nicely. If some stalks turn brown prematurely the bulb is probably diseased and should be 
destroyed with all the foliage. 
STORING: Bulbs may be stored in flat boxes to dry and cure. They should not be more than four inches 
deep so they will dry well. If wooden boxes with wire bottom are used, curing will be hastened if bulbs are washed 
in one of the wire-bottom boxes with a stiff hose spray. Be sure and use reasonable care so that husks are not torn 
off. Bulbs will be much easier to clean later and there will be very little dirt in the bulblets. As soon as the bulbs 
‘are dry and in the cellar (about three weeks after digging) they should be treated with Napthalene Flakes or 
DDT Dust. The dust may be put on at any time, either dusted on with a hand duster or a small amount placed in 
a paper bag and shaken to distribute the material over the bulbs completely. 
Napthalene Flakes should be put on them in a bag or container so the fumes can be confined. A temperature 
of 70 degrees for three or four weeks should be maintained. About one ounce per hundred bulbs is the best propor- 
tion. Be sure and remove the flakes before the root growth starts in the spring or the new roots will be damaged. 
The bulbs should be cleaned either before or after this treatment. Cleaning means removing the roots and old 
bulb from the base and throwing away all diseased bulbs. Bulblets may be separated at this time, also. 
Again let me emphasize the fact that if your bulbs have thrip, it is your fault, regardless of whether you bought 
the thrip or hatched them in your own planting. DDT Dust 5% will effectively kill thrip on contact. The problem 
is getting contact. In the storage the bulbs must be covered and in the field the plants must be covered after every 
rain. 
The best spray for aphids and other soft bodied insects is Black Leaf 40. We will be glad to include your spray 
and treating materials with your bulb order at the following prices:
