DISEASES OF GINSENG. 59 



Most of the above named diseases have been scientifically 

 taken up for investigation l^y Plant Pathalogists and detailed 

 accounts have been published. The ginseng growers are greatly 

 indebted for aid along these lines to such men as Prof. H. H. 

 Whetzel, James M. Van Hook and W. H. Rankin. Much of the 

 success in combating these diseases must be credited to the helpful 

 suggestions made in publications originating from the pen of 

 these men. 



From what is being said here on diseases of ginseng, it is 

 not to be inferred, that everij ginseng garden is attacked by all, 

 or even by amj one, of these diseases; — circumstances alter 

 cases. It is most important, however, that every ij-ower, in order 

 to be successful, carefully study, and acquaint himself with, the 

 character and nature of the diseases to which his crop is subject. 

 He will then be able to act judiciously and intelligently in combat- 

 ing any disease that miolit attack his plant, and prevent loss 

 by proper precautions taken at the proper time. Whereas, had 

 he not previously informed himself, he would likely not detect the 

 presence of the disease until after it had gained a strong foothold, 

 or perhaps not, until after it had made such headway that the ciop 

 would be beyond redemption; and to begin studying then, would 

 be like "covering the well after the child has been drowned-" 



The following, partly copies of, and jjartly extracts from, a 

 number of such published accounts, will give helpful information 

 to the growers:
