This paper presents the study results of the efficiency and selectiveness of herbicides based on dimethenamid + acetochlor, S-metolachlor + prometryn, S-metolachlor + linuron and acetochlor + linuron in production of poplar planting material. The study of the efficiency and selectiveness herbicides was performed during 2004 at the experimental field of the Institute of Lowland Forestry and Environment in Novi Sad. All investigated combination of herbicides the reduction of weed number and weight of weeds per unit area. The best efficiency in the reduction of the number and weight of the weed was shown by the combination of herbicides acetochlor + linuron. The investigated herbicides did not have a depressive effect on the growth of poplar rooted cuttings.
