Abstract: The research was conducted during 2011 - 2013 in the experimental field of the Department of Plant Production in Agriculture Faculty at Trakia University. Stara Zagora. The field experiment was performed with three varieties of common wheat: Enola, Illico and Ingenio. The objective is to determine the influence of the imported herbicide formulations on the performance of common wheat and determination of the most valuable technological options regarding the stability of the yield. Variants of the experiment are as follows: 1. Control - no treatment with herbicides; 2. Axial one - 1000 ml.ha-1; 3. Lintur + Traksos 150 g.ha-1 + 1200 ml.ha-1 - tank mixture; 4. Logran + Traksos 37.5 g.ha-1 + 1200 ml.ha-1 - tank mixture; 5. Lintur + Axial 150 g.ha-1 + 900 ml.ha-1 - tank mixture; 6. Logran + Axial 37.5 g.ha-1 + 900 ml.ha-1 - tank mixture; 7. Lintur + Axial 150 g.ha-1 + 600 ml.ha-1 - separate treatment;8. Lintur + Traksos 150 g.ha-1 + 1200 ml.ha-1 - separate treatment; 9. Logran + Axial 37.5 g.ha-1 + 600 ml.ha-1 - separate treatment.10. Logran + Traksos 37.5 g.ha-1 + 1200 ml.ha-1 - separate treatment. Synthesis criterion for stability YSi by Kang taking into account both the stability and value of production, shows that in terms of technology growing, technologically the most valuable is the variant of decoupling Lintur + Axial (10+). Axial one herbicide was highly complex assessment (11+) for technological stability of yields. In varieties Illicо and Ingenio most technologically valuable options appear involving herbicide Axial one (12+) and separately imported Lintur + Axial (5+).
