The results of the long-term study of the level of agrophytocenosis of winter wheat, in view of the change of the predecessor, are described. The influence of three common predecessors in the technology of winter wheat cultivation, namely, clover, soybean and corn, is estimated. It has been proved that the most favorable conditions for controlling the number of weeds in winter wheat agrophytocenoses are achieved in different years of hydrothermal provision when used as a precursor of the classical clover. It was established that the use of optimal precursor under winter wheat allows to reduce their number on the unit area at least 13-18,7 %.
