Narcissus Fly 
100% CONTROL FOR NARCISSUS BULB FLY 
_ Mr. Charles F. Doucette of the Ornamentals 
Insect Research Laboratory, U.S.D.A., Sumner, re- 
ports that growers who used the suggested preplant- 
ing soaks of daffodil bulbs last fall find their stocks 
completely free of bulb fly infestation this summer. 
Because of its general availability last year chlordane 
was used in most places. Heptachlor was used by 
several growers. Last season’s experiment, as re- 
ported in the Florists’ Review of January 9, 1953, 
indicated that the period of soaking need not exceed 
10 minutes. This season’s tests corroborate this. 
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 chlor- 
dane 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 con- 
centrations, 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: 
Heptachlor Chlordane

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 acetate 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.

SHOWING DAFFODILS 
A few simple rules about showing daffodils fol- 
low: If at all possible show single specimens in bud 
vases, with one leaf; show either three or five flow- 
ers 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 posi- 
tion 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.
