D. D. T. FOR THRIP CONTROL 
Did you know that Thrips can ruin the majority of your blooms? You 
may be unaware of their presence until your blooms fail to open or are de- 
formed. Thrips remain hidden in the leaf sheath only emerging at night or on 
a cloudy day. A simple and effective control is the application of 5% D. D. T. 
dust at one week intervals from the time they are 6 inches high until the first 
bloom opens. This may be applied with an inexpensive duster or if you raise 
a very few, a porous cloth bag may be used shaking gently over each plant, 
preferable after watering or in the early morning after a dew. 
We use this protection in our storage as well as in our field. All trays are 
dusted lightly in storage to insure a complete kill. Thrips in storage will sap 
the strength from your bulbs to a point where they may not even grow. Any 
bulbs purchased from us will be free from Thrips, however, this insect may 
be on certain other flowers in your garden or may be carried in by the wind 
or on clothing. For this reason, we also recommend use of 5% D. D. T. dust 
on your bulbs in storage. 
The best part about using D. D. T. dust is that there is no danger to the 
plant or bulb if an excessive amount is used. 
CAUTION — If inhaled by humans a temporary toxic condition may 
develop but no permanent effects will be felt. Ordinary care will insure no 
harm to the person making the application.
