According to the results of the research it is established that the maximum effect in the control of Sosnowski's hogweed is achieved by applying chemical measures in the complex of herbicides based on the active substance glyphosate in the form of acid, 500 g / l, normally 8 l / ha with dicamba, 480 g / l , at a rate of 0.3 l / ha, as well as the use of biodestructor at a rate of 2 l / ha on mown and dried plants, which ensures the destruction of vegetative and root mass of plants and prevents seed maturation, reducing the likelihood of germination. When testing this complex in a number of foci, the density of weeds decreased from 47.8 and 43.5 units / m2 to 4.8 and 1.2 units / m2. This made it possible to reduce the number of Sosnowski's hogweed in some hearths by more than 25 times. According to the monitoring conducted in 2020, the areas where Sosnowski's hogweed was not detected decreased by 17 hectares compared to 2016, as well as the receipt of significant areas where the number of weed plants is less than 1 piece / m2. The survey showed varying degrees of detection of various fungal infections. Diseases such as mold, fusarium wilt, Alternaria phomosis, present in all foci and formed their permanent population structures Product Description popup.authors Hunchak Volodymyr M Solomiichuk Mykhailo P popup.nrat_date 2021-01-11 Close
