The most appropriate herbicides, their choice, application dates and methods were determined in the investigations comprising 16 ornamental plant species, both annual and biennal ones. The respective tests were carried out in 1976-81 at the Experiment Stations Mutowo and Baranowo on light loamy soil with the humus content of 0.7-1.2 percent. Possibility of killing 70-80 percent of weeds with use of the herbicides tested as well as harmlessness of the most of them for seed yield and its sowing value have been proved. The sets of the most efficient herbicides for the plant species tested have been recommended. The best results were obtained at a presowing application of Kerb 50 W and/or Treflan 2 EC. After emergence the best appeared to be the herbicides of Ramrod, Wenzar and Tenoran. However, their effect depended on the meteorological conditions. Herbicides killed almost fully weeds in seedbeds of Phlox drummondi, Lathyrus odoratus, Calendula officinalis, Helichrysum bracteatum and Matthiola bicornis.
