HYDROCYANIC GAS FOR WHITE 

 FLY. 



Editor of HORTICULTURE: — 



My greenhouse is very badly in- 

 fested with white fly and I would 

 like to get rid of them before bed- 

 ding out in the garden. 



Can you through the medium of 

 your reliable paper give me the for- 

 mula for and instructions in the us3 

 of hydrocyanic gas for the extermina- 

 tion of this pfest? 

 Canada. W. T. 



In answer to the above query we 



copy the following directions from 



Bulletin No. 123 of the Massachusetts 



Agricultural Experiment Station: 



HYDROCYANIC ACID. 



For Nursfery Stock. 



Potassic cyanld (98 or 99 per cent). 

 Sulfuric acid (1.83 sp. gr. commer- 

 cial ) . 



Wafer. 



Multiply the number of cubic feet 

 to be fumigated, by .2 or .25, giving 

 the number of grams of cyanid 

 needed for the house or box; divide 

 the answer by 28.35, giving the weight 

 of the cyanid in ounces. Take twice 

 as many fluid ounces of acid and four 

 times as many fluid ounces of water 

 as was taken in ounces by weight of 

 the cyanid. Mix the water and acid 

 in an earthen or granite-ware jar, then 

 by loose bag and string drop in the 

 cyanid after tghtly closing the place 

 to be fumigated. Leave close 40 min- 

 utes, then open from the outside and 

 air for at least ten minutes before 

 entering. 



White Fly in Greenhouse. 

 Fumigate as for Nursei-y Stock 

 above, No. 25, except that instead of 

 using .2 or .25 gram of cyanid per 

 cubic foot, use .007 to .01 gram accord- 

 ing to how tight the hous'e is. Use 

 the corresponding proportions of sul- 

 furic acid a-nd water, fumigate at 

 night for three hours, and then venti- 

 late. Repeat the fumigation two 

 weeks later and a third time two 

 weeks later. This treatment must be 

 used with caution, as tender plants 

 may under exceptional conditions be 

 somewhat injured.

SPRING PLANT TRADE IN CHI- 

 CAGO. 



After an almost unprecedented spell 

 of rainy weather, Chicago is suddenly 

 subjected to midsummer heat. The 

 effect on the wholesale plant market 

 has been little less than marvelous. 

 One of the largest of the Chicago 

 growers says there has probably been 

 more trade in bedding plants crowded 

 into the past few days than ever be- 

 fore in so short a time. Notwith- 

 standing the fact that the late Easter 

 and the long and unusual dark and 

 rainy spell has had a tendency to 

 weaken and retard trade, if the hot 

 weather continues we will have a 

 record breaker in the sale of bedding 

 plants for Memorial Day. There 

 seems to be nothing new in bedding 

 stock but the old standbye in gerani- 

 ums, verbenas, pansies, etc, are hold- 

 ing their own and finding ready pur- 

 chasers. Immense as the stocks of 

 some of the Chicago growers has 

 been, it was pretty well sold out sev- 

 eral days before Decoration Day. 



In last Week's Issue of HORTICUL- 

 TURE, page 698, we located the A. E. 

 Kunderd Gladiolus Gardens at Ken- 

 dallville, Ind. We should have said 

 Port Wayne. 



Massachusetts has recently appro- 

 priated $34,000 for a range of green- 

 houses of modern type and attached 

 instruction building for use of the 

 floricultural department of the agri- 

 cultural college at Amherst.
