Research results of the determination of the effective doses of herbicides for the weed control in the seedings of feed blue lupine (Lupinus angustifolius) of Mitan and Pershatsvet varieties and specification of variety reaction to herbicides application were presented. Application of the mixture of soil herbicides gezagard (3 l/ha) + primekstra gold (1,0 l/ha) proved to be the most effective for Mitan variety. The average number of weeds was 20 pcs/m2. Percentage of weed losses was 89%, the average yielding capacity was 26,7 c/ha. Application of gezagard + primekstra gold mixture lowered seed yields and provided the average yielding capacity of 25,1 c/ha. Application of pivot herbicide (0,5 l/ha) provided seed yield of 25,2 c/ha and 68% of weed losses. Application of gezagard + primekstra gold mixture also was effective for the Pershatsvet variety. It provided 87% of weed losses over two years and seed yield of 25,9 c/ha. Application of gezagard + primekstra gold mixture proved to be effective and provided 86% of weed losses and 24,6 c/ha of seed yields. Application of zenkor caused the oppression of plant habit and lamina heat injury
