Sensor-based detection of mycotoxine producing fungi in wheat crops
Project
Project code: 0339992B
Contract period: 01.07.2006
- 31.12.2009
Budget: 88,225 Euro
Purpose of research: Applied research
Products made from cereal grain can contain toxins originating from fungal ear diseases. In wheat, the most occurring toxic ear pathogen is head blight caused by Fusarium spp.. Mycotoxins are dangerous in human and animal nutrition. An automatic detection in the field by machine vision could help to obtain information about the severity of the disease infection very rapidly. Before the harvested product goes into storage or is processed further, monitoring results could be used to decide whether the grain is to be used for human or animal nutrition or should even be put aside. Digital image analysis would offer a non-destructive, non-contact and fast tool for recognizing diseased ears. Digital cameras as on-line sensors can be carried on tractors and may be operated at common speeds of agricultural machines. In the project hyperspectral, thermography, chlorophyll fluorescence and colour images are to be tested on artificial infected wheat plants in the laboratory but manly under outdoor conditions in farmer’s wheat fields. A high wheel tool carrier will be equipped with a mechanical system on which different cameras are fixed. A simple and straightforward algorithm is to be developed to fuse the spectral information to detect diseased ears. Research work is focussed on the following two main problems:
* Evaluation of the detection reliability
* Determination of the specific date of the epidemic of the disease, when symptoms are detectable (time series).
