Results of the realized in 2007-2008 searching field experiments on the study of usage of different herbicides and their mixtures in weed control after the emergence of buckwheat (Fagopyrum sagittatum) sprouts of the determinate diploid Karmen variety realized on average-cultured sod-podzolic light loamy soils of the Republic of Belarus were presented. It was established that for the improvement of the efficiency of chimerical weed control in seedlings of buckwheat crops there were could be used the herbicide mixtures of betanal expert OF with goltix(0,5 + 0,5 l/ha) and betanal expert OF with lontrel (0,75 + 0,22 l/ha) at the stage of cotyledonous leaves which in course of two years made it possible to obtain the average increase of yielding capacity of buckwheat crops up to 6,4 c/ha (30,5%). In the conditions of application of the same herbicide mixtures at the stage of the first real leaf the increasing the yielding capacity lowered up to 1,9 and 1,5 c/ha (9,1% and 7,0%), respectively. Yield increase of buckwheat caused by application of fyuzilad forte (1,5 l/ha) at the budding stage depended not only on the amount of cereal weeds, buy also on the herbicides applied before and after buckwheat germinating seedlings
