DISEASES OF GINSENG. 97 



To be sure, many beds to which lime had never been av)plied 

 showed fiber rot, but the amount of injury in these was usually in 

 marked contrast to that in beds treated with the lime. 



While we could make no definite recommendations for con- 

 trol last season, we suggested to the growers the desirability of 

 giving the acid phosphate treatment a trial. In view of Brigg's 

 work on the disease on tobacco it seemed reasonable to expect 

 similar results on ginseng. Many growers consequently under- 

 took to treat from one to sevei'al of their beds. Many of the gar- 

 dens so treated have been visited by the junior writer this season 

 and a summary of the results as obtained by the growers, as will 

 be seen from the following report, warrant us in recommending 

 the use of acid phosphate at from one thousand to two thousand 

 pounds per acre, on ginseng beds where filier rot has given trou- 

 ble and especially on beds where seed is to be sown.
