Because the wheat is infected with the gibberellic disease can be reflected on the ear of the wheat and also can be reflected on the concentration of scab pathogenic spores in the environment surrounding the wheat and the air, the method comprehensively confirms whether the wheat is infected with the scab and the infection degree by respectively detecting the form of the wheat, the surrounding environment and the concentration of the scab pathogenic spores.
