Abstract

Powdery mildew is one of the major diseases of facilities vegetables. In order to achieve early, fast, and accurate diagnosis of powdery mildew, with TCS3200 color sensor and infrared sensor as detecting port and 12864 dot matrix LCD as display, the system explores the external change such as the color change of the blade in health and disease stage and change of reflection spectra. Through tracking experiment of different stages of cucumber leaves infected, the results show that the system can identify change of optical frequency values and the RGB values in the health cucumber leaves and infected cucumber leaves and thus provides effective warning alarm for controlling early disease occurrence.
