Excerpt from Ear Rots of Corn
Some of these ear rots are so similar that the casual observer rarely entertains any suspicion of there being but one form; The resemblances are so complete in some instances that the removal of the husk and sometimes a microscopical examination are needed for the classification of the variety. Commonly, however, in fairly advanced stages of the disease one or more characteristic differences are apparent. The two forms most likely to be confused, and the only ones which as a rule involve the husks, may be distinguished by the color of the mold like growth. In the case of the Diplodia disease this is white, while in that of Fusarium II. It is pink to red.
The first indication that ears of corn are diseased is a fading of the bright green of the husks to a pale yellowish green color. In the Diplodia disease this change goes on gradually, and under favorable conditions quite rapidly, until the entire ear has an appearance of pre mature ripening. While this change of color on the outside is pro gressing one finds that the inner husks have not only lost their normal color,' but are more or less tinged with brown, particularly along the advancing margin of the diseased area. (pl. This condition is much more striking in some ears than others. With the advance of the disease the outer husks grow darker and darker, frequently becoming dirty to sooty black in appearance, when they present a striking con trast to those of normally ripened ears.
