Undertaking revegetation of areas of hogweed using different techniques, e.g. soil cultivation

As a result of revegetations studies integrated management system was worked out providing control of Giant Hogweed and re-establishment of biodiversity in arable areas. Glyphosate (herbicide) treatment after substantial spring growth ensures control of Giant Hogweed rosettes, seedlings. Deep ploughing (up to 25cm) 2-3 weeks after herbicide application is effective soil cultivation method, because of cutting Giant Hogweed rosette plant roots and turning upside-down upper soil layer where majority of seeds is concentrated. Sown grass mixtures (componenets - competitive, produce dense swards, with high re-growth potential under frequent cutting) provide uniform covering of the soil after elimination of previously prevailing component of phytocoenosis -Giant Hogweed. Dicot plant species appear in treated areas later increasing biodiversity of phytoceonosis. Dicot herbicide application ensures hogweed seedling and other dicot weed control in early grass sward development stage. Cutting treatment beside hogweed control increases grass sward density, because of tillering stimulation. For control of Giant Hogweed in riverside's areas, where chemical treatment is prohibited, a method for creation of a strong competitive plant community and depression of Heracleum spp has been selected. Method combines sowing of grass mixtures (high seeding rate) and frequent cutting by hand mower.
