PRECONDITIONS FOR AUTOMATIC LASER TREATMENT OF WHEAT GRAIN

The paper describes two sets of experiments of low-power diode laser treatment of wheat grain. Grain was artificially infected with various fungi, such as Penicillium, Fusarium, Alternaria, etc. in two intensities (high, low), and the experiment tried to establish the effect of laser treatment as compared to chemical treatment on sprouting efficiency (defined as percentage of total kernels that sprout after an specific incubation time), and on fungus survival (expressed as level of infection). An experimental conveyor belt system was build to expose the kernels to laser light in the latter case. Laser treatment was to some extent effective in increasing sprout efficiency and reducing fungus survival, although less effective in these preliminary experiments than fungicide treatment. This paper proposes laser beam treatment as environmentally safe alternative to chemical treatment of almost any type of grain.
