DIGITALIS DISEASE PROBLEMS

Anthracnose causes purplish-brown spots on the leaves.      
The spots may be very small at first but grow to an eighth  
inch in diameter.  There may be a purplish border around    
the spots.                                                  

Leaf spot causes brown spots with reddish borders.  The     
spots have irregular shapes and are one-fourth inch in      
diameter.  The lower leaves are most frequently attacked.   
A heavy infection causes death of the entire leaf.          

Root and stem rots of various sorts decay the roots and     
stems.  Infected plants should be destroyed.                

Verticillium wilt kills plants occasionally.  Avoid         
infested soil and destroy infected plants.
