Probably due to local Infec- tion by soil organlsma. and preventlble by using boards for blanching. CHERRY. Browk-rot. Thia la chiefly destructive to the sweet cherry. This Is chiefly grown, however. In the Dry Belt, where the diaease Is not serious. If i)rpseMt at all. In the wet climate of the Lower Mainland, In seasons which favour the disease, It Is often not possible to control It profitably, especially as the conditions which contribute to Its severity also cause other damage, such as the splitting of the fruit. An account of the disease and Its control will be found under " ;. Fig. 4. Brown-rot on swoet chorrfcs. Tho lower figure shows a series of different stages In the development of the disease. GUUMOSIS. The cherry. In common with other stone-fruits. Is very liable to suffer from this, the sweet cherry especially so. The cell-walls break down and are changed Into gum. which exudes and dries In masses on the bark. Often this follows wounds or frost- injury, but It may be spontaneous, as In wet seasons or situations, or where growth has been forced. In the case of gununing from wounds, where these are of any size, they should be cleaneil out and disinfected. The bacterial gumniosls due to a specific organism, and which Is so deatructlve In Oregon, has not been obaerved 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 Eastham, J.
