The organisms which cause plant disease can destroy crops from
the time the seed is put into the ground until the crop is
harvested and in storage. Some diseases are capable of totally
destroying a crop, while others may cause only cosmetic damage.
However, cosmetic damage may be equivalent to total destruction in
the case of ornamental plants.
A basic understanding of diseases and how they develop will give
an appreciation for the complexity of the problem and demonstrate
the importance of cultural practices in control of diseases.
