The aim of this study was to determine the phytotoxicity and efficacy of the herbicide ace- tochlor with dichlormid (preparation ACETOCHLOR 768 + DICHLORMID 128 EC) and a possibility for its application in a foliar control of broadleaf weeds in corn crops. In 2012 there was conducted a serie of trials in accordance with the standard EPPO method, to examine the efficiency of this preparation, on the Zemun Polje locality. The experiment included four treatments: two for efficacy (ACETOCHLOR 768 + DICHLORMID 128 EC 2,0 l/ ha and 2,5 l/ha), one for phytotoxicity (ACETOCHLOR 768 + DICHLORMID 128 EC 5,0 l/ha) and one as a standard (ACETOGAL PLUS 2,5 l/ha). The product was applied after planting and before germination of corn and weeds. Acetochlor as a selective herbicide from the chemical group of chloroacetamide did not show any phytotoxicity to corn, if applied in recommended quantities and on the recommended application time. Acetochlor with di- chlormid showed very high efficacy in the control of weeds such as Echinochloa crus-galli, Setariaglauca, Sorghum halepense (s), Bilderdykia convolvulus, Chenopodium polysper- mum, Datura stramonium, Solanum nigrum and Stachys annua.
