It is shown, that under the influence of aftereffect of herbicide pivot, applied on previous peas, decrease in weeding of winter wheat, quantity of plants and productive stems was marked, and it was increased in the process of the pivot rates augmentation and took place against a background of all applied sulphonylurea herbicides. Use of the last promoted the increase of productive plant stand of winter wheat. Quantity of grains in an ear and mass of 1000 grains of winter wheat depended both on aftereffect of pivot, and on the influence of sulphonylurea herbicides, and, for this, the character of this law exhibiting on different herbicides was unequal and was defined by their influence on crops weed infestation and density of a productive plant stand. Productivity of winter wheat grain under the influence of aftereffect effect of maximum pivot rate, as a rule, decreased. Thus, decrease of this crop grain productivity increase under the influence of the majority of sulphonylurea herbicides took place. Laren has provided the greatest economic benefit by winter wheat cultivation
