  • Rapid diagnosis method of citrus huanglongbing
    Patent number: 9921213
    Abstract: The present invention discloses a rapid diagnosis method of citrus huanglongbing. In the present invention, the accuracy of diagnosis of citrus huanglongbing is significantly improved in the following manners: eliminating the interference of residual starch by effectively removing the residual starch contained in the leaf; eliminating the interference of chlorophyll by effectively removing chlorophyll; and directly developing the color on the leaf rather than mixing and grinding the leaf in water, so as to avoid the problem that the accuracy of color development reaction conducted by mixing the leaf with water is liable to be interfered since the starch is insoluble in water. Therefore a rapid diagnosis of the citrus huanglongbing with much higher accuracy is achieved, which provides effective detection means for the control of the citrus huanglongbing and is beneficial for the control of the citrus huanglongbing.
