^ ^ Naphthalene 

 as a 

 Greenhouse Fumigant 



By W. D. Whitcomb 



Naphthalene fumes may be used to kill certain greenhouse pests, 

 particularly the common red spider, which are not controlled by the 

 standard fumigating materials containing nicotine or hydrocyanic acid 

 gas. This bulletin is intended to supply specific information regarding 

 the conditions under which greenhouse fumigation with naphthalene 

 is both safe and effective.
