METHOD FOR DETECTION OF WILD STRAWBERRY FUNGAL DISEASES Russian patent published in 2020 - IPC A01G7/00 G01N27/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used for non-invasive detection of fungal diseases of plants in horticulture, in carrying out measures for their protection. In implementing the method, reactive resistance of vegetal tissue of a healthy strawberry leaf is measured on one plant at a fixed frequency ƒ₀ located in the tissue bioimpedance α dispersion area and memorized it. Then reactive resistance of vegetal tissue is determined on diagnosed sheets of strawberry plants with suspected damage of leaf fungous disease at the same frequency ƒ_0, and ratios of reactive resistance of the analyzed leaf to reactive resistance of healthy leaf (damage coefficients) – k_i are determined. If the ratio k_i≥1.1, it is considered that the this plant is exposed to a biostressor – a causative agent of fungal disease. If observing fungal diseases of wild strawberry, fixed frequency ƒ₀ is selected within 800 to 1,200 Hz.

EFFECT: higher reliability of detection of fungal diseases of wild strawberries and reduction of costs for its implementation.
