OREGON BULB FARMS 
GRESHAM, OREGON 
Growers who used the suggested preplanting soaks of daffodil bulbs last fall 
found their stocks completely free of bulb fly infestation this summer. Because of 
its general availability chlordane was used in most places. Last season’s experi- 
ments indicated that the period of soaking need not exceed 10 minutes. Complete 
protection against bulb fly attack may be expected. The suggested dosage for 10 
minute soaks of the bulbs before planting are 1 pound actual heptachlor per 100 
gallons or 4 pounds actual chlordane for 100 gallons. The material should be in 
the form of emulsifiable concentrate. Heptachlor is usually available in a 25% 
strength, containing 2 pounds per gallon. Chlordane is available in 2 concentra- 
tions, one with 4 pounds per gallon, the other 8 pounds per gallon. Amounts 
needed for various amounts of water of these materials are as follows:

To prevent spread of basal rot by the solution it is essential that a fungicide be 
included. Both materials are compatible with the 2% Ceresan or the phenyl 
mercuric ecetate in general use for basal rot prevention and the most desirable 
method is to use the insecticide in combination with either of these fungicides as 
usually used against basal rot. As a disinfectant only formaldehyde may be used 
at the rate of 1 quart to 100 gallons. 
We are often asked to suggest a scoring system for judging daffodil blooms or 
arrangements. The following is the system we have used:

A few simple rules about showing daffodils follow: If at all possible show single 
specimens in bud vases, with one leaf; show either three or five flowers in a larger 
vase, flanked with a leaf on either side. Arrange the flowers in your hand, then 
put them in the vase, facing you and hold them in position by inserting a wad of 
sphagnum moss in the neck of the vase. Set your vases about 12 inches apart, in 
rows, on a table, raising the second and third rows by placing planks on bricks, 
upturned flower pots or boxes. Cover the table with black or dark green.cloth and, 
if possible, intersperse the display with small potted ferns or other green plants.
