Determination of time and rate of glyphosate-containing herbicides application to control cow parsnip ((Heracleum sosnowskyi Manden.)

Abstract

The influence of glyphosate-containing herbicides on growth and development of cow parsnip is studied: they can be applied in spring after cow parsnip after growing or by growing plants after carrying out the next plot cutting. The time of glyphosate-containing herbicides application is restricted by early stages of the invasive species development. The duration of glyphosates herbicidal action does not increase 2–3 months, what demands minimum two times plot treatment during the vegetation season.
