In course of the research there was studied the effectiveness of weed control measures in blue lupine (Lupinus angustifolius) plantings in the conditions of the Republic of Belarus in 2008-2010. The research was realized in Vitebsk region on sod-podzolic light loamy soil (humus content – 2.06 – 2.12%, pHKCl – 5.1 -5.9, P2O5 -95 – 170 mg/kg, K2O – 141 – 195 mg/kg of soil). Cereals were preceding crops of blue lupine. As a result of realized research it was revealed that soil herbicide Primextra Gold TZ (2.0-25 l/ha) was more effective than preparation Gesagard (4.0 l/ha), increasing yield by 5.7-7.4%. In the conditions of sufficient moistening Primexta Gold TZ had an advantage over the double usage of herbicidal mixture of Betanal 22 + Goltix (0.5 + 0.75 l/ha) in the phases of 1-2 and 3-4 leaves of blue lupine, providing yield increase by 4.7-6.1% on average. When soil herbicides were applied in the conditions of excessive moistening they have a certain phytotoxic effect on blue lupine and were inferior to the influence of postemergence use of Betanal 22 + Goltiks mixture.
