In-Depth Information
fungus causes damping-off of seedlings, root rots of many plants, and brown
patch of lawn grasses. There are lots of plant diseases, and there are lots of
fungi causing them, but there are not nearly as many separate pathogenic
organisms as all the names would indicate. Thus, a Linkage Reference guides
the user to two or more common disease sites, i.e. “Canker” or “Blight”, where
the user searches for the pathogen alphabetically or the link may guide the user
directly to a pathogen in another chapter or section.
I cannot think of anything more deadly than ploughing straight through
this section from Anthracnose to Wilts. By doctor's orders, take it in small
doses, as needed. But do read the few introductory remarks as you look up
each group, and please, please, before starting any control measures, read the
opening remarks in
Part I
on Garden Chemicals, and look up, in the list of
chemicals, any material you propose to use, noting precautions to be taken
along the lines of compatibility, weather relations, and phytotoxicity.
Although the disease descriptions, fungus life cycles, and general principles
of control given here will remain fairly valid, it must be stressed that
chemicals suggested for control are constantly changing. Today's discovery
may be obsolete tomorrow. This
Plant Disease Handbook
should, therefore,
be used in conjunction with the latest advice from your own county agent or
experiment station. Addresses of the state agricultural experiment stations are
