PR 1: FACE. 



Growers of the eiilhi lily have suffered serious losses for several 

 3'ears from a soft rot which freijueutly destroys the ])lants just before 

 or duriuo- the flowerino- pcM'iod. A bacillus has been separated from 

 the decayed portion of the calla in pure cultures and by repeated inocu- 

 lations has been shown to l)e the cause of this destructive disease. 



In addition to the principal morphological and physiological char- 

 acters of the organism which are described in this l)ulletin. several 

 preventive measures are suggested which have been found to be 

 satisfactory in holding the disease under control. As the bacillus 

 producing this disease is also capal)le of attacking many of our food 

 plants, growers of vegetal)les should guard against any possible con- 

 tamination of the soil with it.
