METHOD FOR MONITORING DYNAMICS OF DEVELOPMENT OF FUNGUS DISEASE OF GARDEN STRAWBERRY Russian patent published in 2022 - IPC A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for monitoring and early detection of fungal diseases of horticultural crops directly on their plantations, when carrying out measures for their protection. According to the disclosed method, one healthy leaf blade of one ternary leaf of the plant is selected on one plant to determine reactive resistances, on which two identical tetrapolar electrode systems with two current and two measuring electrodes are applied perpendicularly from the central vein. First electrode system is located on a section of a leaf plate without signs of damage, and the second - on the part of the leaf plate with the most probable infection by the fungus-pathogen, at a fixed distance from the first electrode system, wherein the measuring electrodes are connected oppositely. Difference in change of signals from them is used to determine the dynamics of affecting the fungal disease of the selected section of the strawberry plantation over time. Maximum fixed distance between electrode systems is determined by the length of the selected plate of the tripartite leaf of the controlled plant, at which overall dimensions of electrode systems are in direct electrical contact with biological tissue of leaf plate.

EFFECT: invention makes it possible to reduce labour intensity of the method, to increase reliability of detection of strawberry fungus disease and to obtain necessary data on clinical course of disease in real time.
