Fructifications not often seen ; on the accompany ing specimens 
they show in typical form, as pinkish spots, more or less concen-

causes the solution to form drops which roll off the polished

In addition to spraying, all diseased leaves should be collected 
and burned, as Colletotrichwin is a form-genus (=the conidial
