GAS FOR WHITE FLY. 



I am bothered with white fly and find 

 I cannot kill it with any of the different 

 kinds of fumigating tobacco, so thought 

 I would try the new way of using hydro- 

 cyanic acid gas. I have a grapery 

 20x51, a palm house 24x26, a rose house 

 20x26 and a general greenhouse 18x40. 

 The grapery is arched from floor to ridge 

 and is twelve and one-half feet high. 

 The palm house measures nine feet to the 

 eaves and eighteen and one-half feet to 

 the ridge. The rose house is six feet to 

 the eaves and twelve feet to the ridge. 

 The greenhouse is five feet to the eaves 

 and eleven feet to the ridge. As I have 

 never used the gas, would you please tell 

 me the quantities required for each 

 house? I can fumigate the grapery and 

 palm house separately, but should have 

 to fumigate the greenhouse and rose 

 house together, as the entrance from the 

 rose house to the greenhouse is partly 

 open. 



Does it make any difference what is 

 the temperature of the houses when the 

 gas is used, and does it kill mealy bug 

 and scale at the same time? I have a 

 fish pond in the rose house, about 7x16, 

 with goldfish in it, and a stage over all 

 to stand plants on. Some say it will 

 kill the fish. Could I protect them by 

 covering with canvas bags or paper? I 

 have never thought it quite safe to use 

 the gas, but the fly is becoming such a 

 nuisance that I must try to get rid of it. 

 The greenhouse and rose house both con- 

 tain a mixture of Primula obconica, P. 

 Chinensis, bougainvilleas, callas, salvias, 

 carnations, geraniums and other bedding 

 plants. J. J. C. 



Hydrocyanic acid gas is the only sure 

 cure for white fly. It is deadly and it 

 would be necessary for you to remove 

 the goldfish from the tank when fumigat- 

 ing, or they will surely be killed. Secure 

 some stone jars to hold the acid and 

 cyanide; no metal or wooden ones will 

 do. Secure as good a quality of sul- 

 phuric acid and potassium cyanide as 

 you can. The lower the temperature, the 

 less liability there will be of injury; for 

 this reason select a cool night for the 

 operation and have the atmosphere of the 

 houses dry. 



For the grapery use two jars, for the 

 palm house two, and two will sufBce for 

 the rose house and greenhouse. A com- 

 paratively light dose will, I have found, 

 clean out the white fly, and my experi- 

 ence has proved that if you use two 

 ounces of sulphuric acid and six ounces 

 of water in each jar and drop in each 

 one ounce of the potassium cyanide, 

 broken up into small lumps, you will 

 generate a sufliciently powerful gas to 

 clean out the fly. As all the eggs may 

 not be killed by the first application, a

second one two or three days later will 

 make sure of them. Move right out of 

 the houses as you drop in the cyanide. 

 See that all ventilators are shut tight 

 and let them remain so all night. Lock 

 the doors securely, so that no one can 

 enter the houses. 



The above proportions will not kill out 

 bug and scale; use treble the quantities 

 for them. Antirrhinums are easily in- 

 jured by gas, but adiantum ferns will 

 withstand quite a dose of it. Tender 

 tomato tops are liable to be scorched, but 

 so few plants are damaged, especially in 

 cold weather, that they are hardly worthy 

 of mention. C. "W. 



Onset, Mass. — J. G. Burrows has been 

 busy getting his new greenhouse stocked 

 for summer visitors. He has several big 

 jobs on hand in the way of landscape 

 work. 



Frankfort, Ky. — Louis D. Singer, for- 

 merly with John A. Keller, of Lexington, 

 Ky., has leased the Henry greenhouses, 

 near Thorn Hill, and will do a general 

 florists' business. 



Lewiston, Me. — Ernest Saunders will 

 erect another greenhouse at his plant on 

 Main street this spring. It will be 200 

 feet long. Last year Mr. Saunders 

 erected a house 600 feet long.
