Depending on the application rate of Fazor, germination of weed beets glomerules decreases. The lowest selected dose of 1 kg/ha reduced the germination of glomerules by 39.5 %, while the dual treatment with this regulator at a dose of 5 + 5 kg/ha causes a reduction in germination by 79.9 %. The most effective application term is in weed beet growth stage BBCH 54. The Roundup herbicide applied to weed beet in the growth stage BBCH 67 had no influence on germination of glomerules and caused plant maturation. With increasing dose of Fazor decreases the number of glomerules produced by weed beets decreases. The negative feature of this product is reduction of the yield of sugar beet tubers.
