Abstract
Abstract
The application of the method of electrical impedance spectroscopy for the diagnosis of plant diseases is justified. Studies were carried out to identify the impedance parameters of strawberry leaf tissue associated with the effects of three pathogens of fungal diseases of garden strawberry, using the impedance analyzer WK 6505B. The analysis of variance of the mean values of the obtained data revealed that the most informative part of the changes in all parameters lies in the low-frequency region of the α-dispersion of bioimpedance. As the main informative parameter, it is proposed to use reactance measured at frequencies of 200 … 104 Hz, at which extremes of its change appear for healthy and diseased strawberry leaf blades.
