E. Smith. of small flies in boxes where there is diseased fruit. One affected fruit in a box communicates disease to the whole. Brown-rot is found in nearly pure condition on the fruit in the orchard, especially on fallen fruit or on fruit hanging low on the tree. It is most prevalent in wet weather or on low ground after irrigation. The fungus is visible to the eye in the packing-house, as a mass of white filaments. It is spread by contact alone. Orchard infection can be controlled by the use of a heavy mulch under the trees, either straw or a heavy cover 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 Stevens, Frank Lincoln, 1871- [from old catalog]; Hall, John Galentine, 1870- [from old catalog] joint author.
