Agricultural bacteriology; a study of the relation of germ life to the farm, with laboratory experiments for students, microorganisms of soil, fertilizers, sewage, water, dairy products, miscellaneous farm products and of diseases of animals and plants. Bacteriology, Agricultural. 330 THE PARASITIC DISEASES OF PLANTS cultures of the organism. It is the cause of considerable losses to horticulturists. Root Tubercles of Legumes.—These have been considered in a different connection (Chapter VII), but they are properly classed here. They are certainly caused by parasitic bacteria, although in this case apparently both the parasite and the host are benefitted by the association, a condition sometimes called symbiosis rather than Fig. 54.—The crown gall on the root of the raspberry. Remedies,—Remedies for the bacterial diseases are not as yet very satisfactory. Spraying, so frequently efi&cient against fungous diseases, is of no value here, because the bacteria are always within the tissues of the plant where the spray cannot touch them. Hence in dealing with plant diseases in general it is always desirable to know whether they are fungous or bacterial since in the latter case spraying is always useless. Each disease has to be met by devices adapted to the peculiar nature of the disease, and no general principles can be given beyond that already pointed out on page 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 Conn, H.
