Losses to cotton, what to look for and where to find it, being one of a series of articles in relation to crops, their common diseases and insect pests to which they are subject . from the normal white to lightbrown or black. Cotton Anthracnose and Boll Rot Anthracnose is a mold-like fungus infection which in-vades bolls, stems, seed, and seedlings of cotton. When a boll becomes infected, the spores spread rapidlythrough the lint and seed, becoming manifest at first assmall round spots, dull reddish or grayish black, whichgradually enlarge until often one-half of the boll is two or three spots become apparent on a singleboll, and, as they spread, finally join together in one largediseased area, affecting virtually all of the boll. Whenthese are cut open, the entire inside is found to be discoloredor rotten. When very young bolls are attacked they are some-times killed outright, while at other times they are dwarfedor affected on one side only. Bolls which are not badlydiseased or those invaded late in their development mayopen an a])parently normal head, but the seed in these dis-eased locks is either destroyed completely or so inoculated 23.
