Abrégé

The invention relates to the field of agriculture, forestry and horticulture and can be used primarily for repelling pests in order to protect trees. The present method includes positioning at least two insulated elongate conductors around the trunk of a tree by winding said conductors alternatingly in a spiral around the tree trunk, and supplying a direct current voltage to the conductors to bring about the formation of an electrostatic field with an intensity of not less than 5000 V/m between the coils of the conductors. The present device comprises at least two insulated elongate conductors positioned around the trunk of a tree by being wound alternatingly in a spiral around the tree trunk, and an electric power source connected to said conductors and configured to supply a direct current voltage thereto to bring about the formation of an electrostatic field with an intensity of not less than 5000 V/m between the coils of the conductors. The invention makes it possible to take preventive measures by repelling pests and thereby preventing the infestation of a tree, to reduce the labour costs of maintenance staff, to increase the degree of operational safety of the device, and to expand the range of means available for the present purpose.
