. The diseases of the sweet pea ... Sweet peas. 48 & Mass. failed to infect the sweet pea after repeated trials both by puncture and atomizer inoculations. In comparing Tables I and II we see that the organisms which infect the sweet pea also infect the apple, with the exception, however, of Gloe. gossypii, which readily infects the sweet pea by atomizer inoculation, but always fails to infect apples on the Fig. 40. Bitter rot of apple induced by the same fungous which causes anthrac- nose of the sweet pea, viz.—Glomerella rufomaculans. The data in Table IV show that none of the organisms used could infect the Rubicon apple on the tree when the fruits were about the size of a large grape. Later, however, by June 26, the first positive infection was obtained with Glom. rufomaculans from the apple. At this same date all the other organisms used failed to infect. On July 15 the same condition prevailed. By August 19, typical bitter rot infections were obtained with Glom. rufomaculans from the apple and sweet pea, Gloe. officinale, Gloe. gallarum, Gloeosporium sp. from May apple fruit, and Gloe. piperatum. Negative results were obtained with Glom. rufomaculans from fig, Glom. gossypii, Gloeosporium sp. from Populus deltoides, Colletotrichum lindemuthianum and 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 Taubenhaus, Jacob Joseph, 1886- [from old catalog].
