The effectiveness of herbicides Stomp 330 EC in weed control and influence of applied herbicides on total yield of tobacco were studied at the Institute of Soil Science and Plant Cultivation in 2006–2007. Stomp 330 EC gave around 100% weed control of Apera spica-venti, Chenopodium album, Anthemis arvensis, Echinochloa crus-galli in both locations. Stomp 330 EC in the dose 4 l/ha caused small plant injuries, however it was not effective in increasing leaf yield. The yield of tobacco on weed controlled plots was higher than that of untreated ones and plots controlled with herbicide Command 480 EC.
