atoms float about in the air, eventually settling 

 on some plant; and, if the foliage happens to 

 be wet, it makes a congenial home, and the 

 pest grows and develops another spot. That, 

 in turn, will propagate thousands of spores. 



There is no remedy for the disease except

There are several other leaf troubles, such as
