SODIUM CYANIDE FOR IRRIGA- 

 TION. 



July 29th, 1919. 



Dear Sir: — On page 59, Volume 30, 

 No. 3 of Horticultoie, published July 

 19th, 1919, I find a summary of a 

 paper on Hydrocyanic Acid Gas in 

 Greenhouses, by William Hunt of 

 Guelph, Ontario. For the most part 

 the information given in the summary- 

 is pertinent. However, it has oc- 

 curred to me that it would be desira- 

 able to call to your attention the fact 

 that sodium cyanide has in recent 

 years practically superceded potas- 

 sium cyanide for fumigation purposes. 

 In fact it is practically impossible to 

 purchase on the American market 

 potassium cyanide suitable for fumi- 

 gation work. On the other hand, 

 sodium cyanide is made in this coun- 

 try and can be purchased from numer- 

 ous dealers. 



Inasmuch as florists will experience 

 great difficulty in securing potassium 

 cyanide suitable for fumigation work, 

 it is suggested that in the near future 

 you advise them through your paper 

 that sodium cyanide is fully as satis- 

 factory as potassium and can be pur- 

 chased in nearly all of the large cities. 



Information on sodium cyanide is 

 given in Farmers Bulletin 880, en- 

 titled "Fumigation of Ornamental 

 Greenhouse Plants with Hydrocyanic- 

 Acid Gas," a copy of which is en- 

 closed. 



Very truly yours, 



E. R. Sasscee, Collaborator.
