" Boll rot," or "Anthracnose," is a disease which may at times be sufficiently serious to destroy from ro to 50% of the crop. The fungus which causes it (Colletotrichum gossypii) is closely related to one of the fungi attacking sugar-cane in various parts of the world.
Anthracnose is the name usually given to a disease which was formerly known as "charbon," "pech" or "brenner."
Anthracnose has been known in Europe for many years, but has only been observed in America since 1881, whither it was probably imported from the old world.
