The herbicides applied before and after the germination of winter wheat varieties have a significant effect on the floristic content change and the structure of the canopy of winter wheat varieties. In wheat crop the following herbicides are used before and after the germination: Glean 75 WP, EL 107 Racer, Banvel DP, Monosan, Racer+Racer, Racer+Banvel DP, Granstar 75 DF, Granstar+Glean, Harmony, Chisel, Dicuran, Banvel P, Banvel DP, Granstar+Banvel DP, Buctril, Satis, Starane M-45, Arcade + Glean, Arcade + X-pand, Glean + Racel, EL.107 + Racer and Treflan + EL. 107. The rate of herbicide efficiency and selectivity as well as their mutual combinations depend on the application time, weed and crop development stage, selectivity width and performing range. Herbicides application in autumn before and after the crop germination is particularly significant in weed control during the germination of winter with satisfying persistence and efficiency to weed varieties germinating during spring. Examinated herbicides Glean, Racer and EL 10 are efficient enough in autumn and residual feature of herbicides extends their performing range to winter and spring weed varieties during the whole vegetation period. Winter wheat variety Niska Partizanska shows satisfying tolerance and selectivity to applied herbicides and selectivity to applied herbicides and selectivity to applied herbicides and application time.
