The researches on study the efficiency of herbicides application at different stages of crop and weed plants development are carried out, the dynamics of weed plant seedlings is retraced. It is marked that the herbicides application in corn crops at earlier stages of crop and weed plants development has got significant advantages over the herbicides later application. As a result of weed infestation decrease by herbicides application at 3 crop leaves stage, corn green weight losses in comparison with hand weeding have made 12,3% in 2003 and 7,6% in 2004., at 6 corn leaves stage the losses have increased up to 47,6 and 19,65, accordingly, what indicates high corn susceptibility with weed competition at early growth stages
