menace than to cure it. Thrips destroy the foliage and prevent blooming; then, 
they may harbor on the bulbs through winter storage. They multiply rapidly at 
temperatures above 50 degrees. If you wish to be safe I advise the following 
four-fold line of attack. ; 
_ First, use every precaution not to have any thrips on your bulbs at digging 
time. Leave all tops in the field, and burn as soon as possible. 
Second, assume that some did get on your bulbs, and that you have them in 
storage. Large growers will fumigate with gas. Small growers will use the safer 
Napthalene treatment. This is to be used during storage only, while the bulbs are 
dormant. Sprinkle one ounce of flakes per hundred large bulbs. Do not place on 
the bulbs until they are thoroughly cured, and be sure to shake out before the 
bulbs begin to sprout or get new root growth in the Spring. If you can keep the 
temperature above fifty degrees for at least several weeks of the treatment all 
thrip eggs will hatch, and you will get a hundred per cent kill. 
Third step. Assume once more that you still have thrips on your bulbs at 
planting time. Then use the corrosive sublimate or Formaldehyde treatment as 
previously explained. This will destroy thrips as well as their eggs. If you plant 
immediately, you may be absolutely certain that your bulbs went into the soil 
free of thrips, or any disease. 
The fourth step is a measure to combat the migratory thrips—the ones that 
might fly in over your neighbor’s fence. There are several sprays that are recom- 
mended. A good spray is made up of 1 oz. of tartar emetic, 2 oz, of brown sugar, 
and 3 gallons of water. These sprays should be applied at weekly intervals until 
the flower spikes begin to show color. Spray with a fine mist. 
If you are one who loves to do things right, you will take all of the above 
four steps, and see that your neighbor takes them with you. They are not expen- 
sive. But it is expensive to buy bulbs, and get no blooms. If for some reason you 
cannot keep in step all through the journey just mentioned, at least take the third 
step, for it is the charm. It is the key to the whole problem. 
DIGGING AND STORAGE—Bulbs should be dug when the foliage begins to turn 
yellow. This is usually about six weeks after blooming. Bulbs should not be 
left in the ground after the plant has died. Varieties that were planted for late 
blooms may have to be dug before the six weeks period for maturity of bulb has 
elapsed. When the early frosts kill the foliage they should be dug anyway. Never 
carry the foliage into your curing or storage room,—it may harbor thrips. Clip 
the tops close to the bulb, and burn when dry. Spread the bulbs three or four 
inches deep in screen-bottomed trays, or thinner if the tray is not ventilated. Cure 
for several weeks either in the open, or indoors, but have plenty of fresh air. Pro- 
tect from intense sun or frost. After curing you may sprinkle on Napthalene flakes. 
Store for the winter in a cool, dry place. Examine occasionally—if bulbs 
are molding, give more ventilation. If condition is serious, expose to direct sun- 
light to kill the mold. 
At your leisure moments during the winter you may remove the old bulb and 
root growth. Before Spring, shake out the Napthalene flakes. 
Your bulbs should now be ready for Spring planting, at which time don’t 
forget the Bichloride of Mercury or other suitable treatment.
