THRIP CONTROL 
The control of this insect is absolutely essential to gladiolus 
culture. Means of prevention is advisable. If thrips are present 
in storage, Napthalene Flakes should be sprinkled over the 
bulbs and covered with papers for a few days. At planting 
time all bulbs should be soaked for a few hours in Bichioride 
of Mercury, 1 oz. to 7 gallons of water. In the field, the foliage 
may be sprayed with Tartar emetic-molasses spray or some 
sod commercial solution, as Rototox. If these precautions are 
ken, practically all injury from disease and thrip may be 
evented. We have never seen any thrip or thrip injury in our 
elds, due perhaps to our precaution and comparative isolation 
om other fields of gladiolus.
