Application of herbicide based on metsulfuron-methyl for invasive plant species growth decrease

Abstract

The herbicide, based on metsulfuron-methyl (Magnum, VDG®) in 2 months after industrial land setting treatment have been effective against Sosnowski’s hogweed (Heraculum sosnowsky Manden.) and goldenrod (Solidago canadensis L.). At the maximum rate of herbicide application of 100–300 g/ha, the hogweed and goldenrod kill has made 100 %. The application of herbicide at the rate of 40–100 g/ha also guarantees the almost complete hogweed and goldenrod control with the preservation of grassy species. The herbicide should not be used on lawn grasses of the first year of life. With the compaction of turf, in perennial meadows, lawns, pastures, the phytotoxic effect of Magnum, VDG® on grassy cenosis is practically absent (applied normally up to 100 g/ha).
