Diseases of the Sugar Beet, 349 The leaves were usuall}^ unaffected until large portions of the fleshy roots had rotted. Cultures from diseased parts again yielded a fungus with structural characters exactly similar to those of the sore shin and damping off fungus. When the beet fungus was first isolated and studied I was sur- prised to find a fungus agreeing in structural details with the one causing damping off, radish rot, &c. The growth characters of the fungi in pure culture were also practically the same, and experi- ments were soon insti- tuted to de- termine if, under any c i r c u m- stances,the beet f u n - gus could cause damp in g- off. In the first exper- iments t o deter m i ne this point, . lettuce and radish seedlings were used. Small pieces of beet on which the beet fungus was growing profusely were put at definitely marked places in a large box of lettuce seedlings on Sept. 26. Similar inoculations were made in a box of radish seedlings, and in both instances checks were observed. On the second day, at every point where the the beet Rhizodonia had been introduced a few lettuce seedlings were diseased, and in five days a considerable area about each piece had damped off. With the radish seedlings damping off was very slow, and no large number of seedlings succumbed ; but in seven days a few plants were affected at about one-half of the inoculation centers. Subsequent work seems to indicate that the fungus from beets does not cause damping off of. 55.—Radishes affected with soft rot of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cornell University.
