The method comprises the following steps: based on machine vision, performing mask processing on an obtained blade image, determining an edge contour of a blade on the basis, and cutting a circumscribed rectangle of the edge contour to obtain a rectangular image; determining a global green mean value of the leaf based on the rectangular image, traversing each pixel point in the rectangular image, determining the pixel point of which the green value is smaller than the sum of the global green mean value and the deviation value as a scab area pixel point, and marking the scab area pixel point in the leaf image to accurately obtain a leaf scab identification result. Scientific basis is provided for reasonable pesticide application of tomatoes, and then the problems that in the prior art, labor intensity is high, soil and planting personnel are polluted due to excessive use of chemical fertilizers and pesticides, and production benefits of unit area are reduced are solved.
