Pri izboru herbicida treba, pored ostalih faktora, prvenstveno voditi računa o sastavu korova, spektru delovanja herbicida, toleranciji gajenih biljaka, zadržavanju herbicida u zemljistu te vremenu i načinu primene. Do sada postoji mali broj registrovanih herbicida koji su testirani u šumskim rasadnicima, pa se u ovom radu ukazuje na mogućnost upotrebe šireg spektra herbicida u zaštiti sejanaca u šumskim rasadnicima od korova, pri čemu je testirano 34 herbicida iz 21 hemijske grupe. Weed control by selective herbicides is today biologically and economically justified in large forest nurseries, because it is the only acceptable alternative to the classical method of weed suppression. In the selection of herbicides, inter alia, attention should be primarily focused on weed composition, the spectre of herbicide effects, tolerance of cultivated plants, retention of herbicides in the soil and the time and method of application. So far, few registered herbicides have been tested in forest nurseries, therefore this paper indicates the possible use of a wider spectre of herbicides in the protection of seedlings against weeds in forest nurseries. 34 herbicides in 21 chemical groups were tested. sejanci, korovi, herbicidi. seedlings, weeds, herbicides. 2004
