Aim of research is to investigate weed harm and develop environmentally safe systems of weed control. Methods of research are generally accepted for research of weed harm and biological efficacy of herbicides. Theoretical results consist in determination of weed harm under condition of their different density and establishment of critical periods of competitive inter-relations of faba beans, lupine and maize. In lupine sowings activity intensification is achieved by application of harness with pivot, and in faba bean - pivot with bazagran. In soybean sowings mixtures of herbicide adjuvants - liposam, EPAA, adju or folicker to working liquids reduced their rates by 30-50%. In maize sowings reduction of the rates of such herbicides as milagro, titus in combination with ammonia saltpeter, EPAA or fertilizer folicker did not reduce their phytotoxic effect on weeds. The level of weed infestation reduced by 75-80 %, and grain yield increased by 1,41 -1,82 t/ha. Novelty - new herbicide compositions that that have phenomenon of synergism are developed, rates of some components reduced by 25-38%. Mew methods of weed chemical control were introduced in soybean sowings, provided keeping of soybean yield within 0,71-0,86 t/ha, net profit was 2560-2720 grn/ha.
