METHOD FOR MAINTENANCE AND PROTECTION OF POWER TRANSMISSION LINES FROM UNDESIRABLE VEGETATION Russian patent published in 2015 - IPC A01M21/00 

FIELD: electricity.

SUBSTANCE: vegetation is treated with herbicides by contact spraying. The preparation is prepared before usage. An analysis of the vegetation physiological state, its species composition, height and volume, degree of the area bogginess, its micro- and macro-relief is performed preliminarily. The preparation is applied onto the top of the vegetation, bottom-up, at an angle preventing lamina tearing off. Next year, upon melting of the snow cover, right-of-ways are treated with an aqueous solution of fertilisers on the basis of N₃₀P₃₀K₃₀-N₉₅P₂₈K_110. The analysis of the vegetation physiological state, its species composition, height and volume is performed. The protected area is divided into areas with the vegetation fit for mowing and the vegetation unfit for mowing. At the first areas the vegetation is removed mechanically. At the second areas the vegetation is treated with herbicides by contact spraying. An aqueous solution of Roundup on the basis of 1.1-1.4 l/ha is used as the herbicide. The solution is applied from top to bottom.

EFFECT: effective ardium.
