In white head cabbage crops, cultivated by nonseedling method research on selection and test of new perspective herbicides in struggle against the weeds applied on vegetation plants were carried out. It is established, that with increase of norm of entering of preparations goal and bazagran amplifies them of inhibited action on cabbage plants, that in further it is reflected on productivity and quality of heads of cabbage. Sensitivity of weed plants to studied herbicides depends on norm of the expense of a preparation and a phase of development of weeds at the moment of sprinkling. Generalizing, the obtained data on selection and test of herbicides acting against weed vegetation in white head cabbage crops in a phase of 6-8 present leaves at nonseedling method of cultivation it is established, that against the background of stomp application herbicides goal and bazagran do not render phytotoxic action on culture and do not cause burns of leaves only at the minimum norms of the expense (goal - 0,2 l/ha; bazagran - 0,5 l/ha). With increase of norm of entering of preparations their abscopal action on cabbage plants amplifies, that further it is reflected in productivity and quality of heads of cabbage
