Features of the tornado and anchor-85 herbicides effect on weeds when creating pine and spruce plantations by sowing

Coniferous forest plantations created by seeding and their agrotechnical care require special attention. Pine and spruce seedlings, due to their small size and slow growth, require high-quality protection from competing herbaceous vegetation. Modern herbicides approved for use in forestry are highly effective and fully comply with current environmental safety standards. There are currently no technological solutions for the use of herbicides when establishing and caring for coniferous cultures by seeding. The aim of the work was to determine the possibility of soil treatment with herbicides to create forest plantations by sowing encapsulated pine and spruce seeds and of carrying out agrotechnical care. The objects of research are forest cultivation areas overgrown with unwanted herbaceous vegetation. Based on the results of the experiments, it was established that the use of the herbicides Tornado and Ankor-85 allows for the successful establishment of forest plantations of pine and spruce by sowing seeds and the implementation of agrotechnical care, which ensures their successful growth in the first years of life. During the chemical treatment of the area under pine and spruce crops in July-September of the year following the treatment, the high effectiveness of the herbicide tornado and its mixture with anchor-85 on undesirable woody and shrubby vegetation was noted. Two years after processing, the high degree of suppression of willow, aspen and birch was completely preserved. Vegetative renewal and the formation of new shoots in hardwoods have not been recorded. During the maintenance of pine and spruce crops with the herbicide ankor-85, a slight suppression of woody and shrubby vegetation was noted.
