Abstract
Abstract The article presents the results of field experiments carried out in the Leningrad Region in 2018 and 2019 with the aim to test the effectiveness of modern herbicides against Sosnowsky’s hogweed and other undesirable herbaceous plants in various types of forest lands: in a clear cutting, spruce plantation, hayfield and on the side of a forest road. The herbicides Magnum (water dispersed granules, 600 g/kg of metsulfuron-methyl), Ancor-85 (water dispersed granules, 750 g/kg of potassium salt of sulfometuron-methyl) and a mixture of Roundup (360 g/l of glyphosate acid) and Ancor-85 were found to be highly effective against Sosnowsky’s hogweed. Magnum stimulates the growth of grasses and is promising for use in areas not occupied by woody vegetation. Anchor-85 is proposed for the care of European spruce ( Picea abies (L.) Karst.) and Scots pine ( Pinus sylvestris L.) in the spring.
