DISEASES OF THE BEET {Beta vidgans) 



Beets are subject to numerous diseases, some of 

 which axe of great economic importance, while others 

 are insignificant and need not be feared by the trucker 

 or gardener. - 



Water-Core Spots 



Cause unknown. 



Arthur' has described a disease of beets which he 

 named water-core spots. 



Symptoms. The disease is characterized by weU 

 defined spots in the interior of the root. These 

 spots greatly resemble the water-core spots of the 

 apple. The spots generally occtu- between the 

 fibrous rings. They are sharply defined and do 

 not grade into the adjoining tissues. The spots 

 range from a pin-head to half an inch in size, 

 and resemble a pea in shape. Sometimes there 

 are but one or two spots in the root, but more 

 generally several are present. The disease does 

 not seem to be of any great economic importance, 

 and it is not likely that any financial losses wiU be 

 attributed to it.
