<P>PROBLEM TO BE SOLVED: To provide a method of treating crown gall disease of trees and root base diseases such as white root rot by a biomaterial alone without using a chemical agrochemical. <P>SOLUTION: A fermented liquor and a fermented material by useful anaerobic microorganisms present close at hand, that is, lactic acid bacterial, yeast fungi, and other useful microorganisms (which are called as Agri vinegar by the inventor) are buried in the part near the root over which an air blocking material such as a vinyl sheet and a polyethylene film is then placed and pressed with soil to completely heal the diseases. The useful microorganisms are anaerobic and perform fermentation in the place where oxygen is scarce to contribute to the functions of animals and plants, and the white root rot fungi and the crown gall bacteria are aerobic and cannot be active without oxygen. The restriction of supplying oxygen by one sheet of an air blocking material allows good microorganisms to work and bad bacteria to be deactivated. Consequently, the diseases are completely healed. Further, when trees are planted with the use of the air blocking material on which the Agri vinegar has been coated or sprayed or which has been dipped in the Agri vinegar, infection with crown gall disease, white root rot and the like can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
