    WEEDS OF ORDU PROVINCE BEECH NURSERY AND THEIR CHEMICAL CONTROL

    Rahim Anin1 and ükran Gökdemir2

    In this study, the most important weed species of Ordu Province Beech Nursery (Turkey) were determined and their chemical control with simazine and chlorthal dimethyl was investigated. The chemicals gave good control of weeds as pre-emergence (simazine: 3.0 kg/ha, chlorthal-dimethyl: 11 kg/ha) and post-emergence (simazine 1.0 kg/ha). The effects of the chemicals on seedling emergencies, seedling heights and seedling dry weights were also investigated and found to have no significant adverse effect on these parameters; the lower effective dosages were found to be recommendable.

    Keywords: Chemical weed control, forest nursery herbicides, weeds, beech (Fagus orientalis Lipsky).
