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 appl

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 Gloe.
