| 摘要 |
The present invention relates to a method for determining a fungal infection of a plant- The method comprises: emitting excitation radiation by one or more radiation sources to the plant, said radiation comprising first excitation wavelengths being within the absorption band of a phenolic compound and second excitation wavelengths being outside the absorption band of said phenolic compound, thereby inducing chlorophyll fluorescence; detecting chlorophyll fluorescence radiation from the plant; and obtaining a value being indicative for the fungal infection of the plant, said value is dependent from the detected chlorophyll fluorescence radiation induced by excitation radiation of the first excitation wavelengths and the detected chlorophyll fluorescence radiation induced by excitation radiation of the second excitation wavelengths. Moreover, the present invention relates to a mobile detection device for carrying out this method. |
