Abstract

A two-year experiment (2002 – 2003) was conducted in oil pumpkin (Cucurbita pepo var. oleifera) at two localities (Vranjevo and Poljanice) to evaluate the effectiveness of chemical weed control through application of herbicides, and to compare it with mechanical weed control. Main weeds were Amaranthus retroflexus, Setaria viridis and Echinochloa crus-galli. All herbicide treatments, except combination of prometrine + fluazifop-p butyl36, in 2002 appeared to be acceptable to high efficacy in control of annual grass- and broad-leaved weeds. The efficacy of all herbicide treatments in 2003 was lower. The best results of herbicide effectiveness were achieved with combination of linuron + dimethenamid (91.3%), trifluralin (90.1%) + napropamide and clomazone + linuron (89%).
