inent of Agriculture for examination, and tlie Pathologist reported as 

 follows : 



The leaves all appear badly infected with fnngus Aseochytci nicotiance. To the 

 best of my information this fungns has not as yet been found within the limits of 

 the United States proper, and we have never heard of its previovrs occurrence in 

 Porto Rico. In past years several reports of its occurrence have been made from 

 various points in Italy. These reports, however, have been very meager, and we 

 know very little concerning its destructive nature and i^ractically nothing con- 

 cerning the methods of control. Judging from the specimens < if leaves submitted, 

 it would appear to be a rather serious disease, and great care should be taken to 

 prevent its spreading into other places. 



It is quite possible that judicious fertilizing would increase the 

 vigor of the plants and render them less susceptible to the disease. 

 The use of a fertilizer containing a rather large percentage of potash, 

 and, if the soil is soggy, careful attention to drainage, might be bene- 

 ficial. Diseased leaves and all refuse from a diseased crop must be 

 burned. 



Some of the results obtained in the experiments are summarized as 

 follows :
