In the conditions of the Republic of Belarus there was analyzed response of yellow lupine (Lupinus luleus) crops to application of new pre-emergence herbicides for weed control. There was evaluated influence of different chemical preparation on field germination, safety and general viability of lupine crops. There was analysed influence of herbicides of the formation of agrocenosis, individual productivity, yield formation elements and grain yields. The results of the research of the application of the soil herbicides in the crops of the fodder yellow lupine of BSAA-382 variety are given. The dependence of a stem formation on field germination, on the number of the undamaged plants and on the total number of the survived plants during the application of chemicals for weed protection is discussed. Influence of chemical preparations on the total number of weeds and their mass efficiency of different herbicides to suppress weed growth. The estimation of the effect of weed infestation on the yields of yellow fodder lupine and the elements of the yield structure are shown. Application of chemical preparations has provided substantial increase of green weight productivity which by all realized variants authentically exceeded the control over weeding on 104,5-171,0 center/hectares, and grain efficiency has increased for 4,5-10,0 center/hectares in comparison with the control over weeding.
