CYANIDE FUMIGATION. 



A Sticcessful Experiment. 



Wishing to test the theory I advanced 

 a few weeks ago regarding the use of 

 pure cyanide instead of the commercial 

 article of uncertain strength for green- 

 house fumigation, we selected a house 

 20x36, even-span, ten feet to ridge, with 

 side walls four feet high. We figured 

 this to contain somewhat more than 5,000 

 cubic feet, but we called it an even 

 5,000. 



This house contained a large variety 

 of plants, as the following list will show: 

 Geraniums, colons, cyclamen, primula, 

 both obconica and Chinese; heliotrope, 

 farfugium, fuchsia, hydrangea, abutilon, 



ferns, smilax, Asparagus plumosus and 

 Sprengeri, cailas, German ivy, petunia, 

 ficus, chrysanthemums, grevillea, palms, 

 dracaena, lobelia, impatiens, rose geran- 

 iums, tradescantia, salvia, Baby Ram- 

 bler and a few potted carnations; in 

 fact, a representative collection of the 

 plants usually found in the majority of 

 establishments. This house was badly 

 infested with white fly, and black 

 aphis was giving us considerable trouble 

 on the chrysanthemums. 



As we were working with a tremend- 

 ously powerful agent, we were a con- 

 siderable time coming to a decision as 

 to the amount to start with, having no 

 data of any value to guide us. We 

 finally decided, however, to try four 

 ounces to 5,000 cubic feet, but not ex- 

 pecting very much in the way of results. 

 Contrast this with twelve and a half 

 ounces, as recommended by W. 8. and 

 others and you can see that we were de- 

 cidedly conservative. 



We took four one-pint fruit jars, filled 

 them half full of a cold mixture of one 

 and a half ounces strong sulphuric acid 

 and six ounces of water, and set them 

 in the walks, two on each side, about 

 ten feet from the ends. Then with a 

 rather delicate pair of scales we weighed 

 out accurately four one-ounce portions 

 of chemically pure ninety-nine per cent 

 potassium cyanide. Each of these was 

 rolled in a small piece of tissue paper 

 (don't use the waxed paper) and the 

 ends twisted tightly. These were then 

 ready to drop in the acid without dan- 

 ger of spilling any. When we were 

 ready we started at the further end and 

 dropped a roll in each jar as we came 

 to it. We closed the house up tightly 

 and left it so all night. 



Upon inspection the next morning we 

 were simply astonished at the result. 

 We could not scare up a live white fly 

 anywhere, but dead ones were everywhere. 

 The black aphis were completely cleaned 

 out. The mealy-bug apparently was the
