The efficacy of several new formulations of copper compounds, namely Cuprozin 35 WP (copper-oxychloride), Cuproxat (copper-sulphate), Funguran OH (copper-hydroxide) and the plant activator Bion (acibenzolar-S-methyl) and their combinations with dithiocarbamates (Dithane M-70) was estimated in controlling Xanthomonas campestris pv. phaseoli (artificial inoculation) in field conditions in two localities in Serbia (Zemun and Smederevska Palanka).There was no significant difference between the efficacies achieved by compounds applied individually and their combinations, except Cuproxat, which exhibited decreased efficacy at low concentration in the locality Zemun. The investigation confirmed high efficiency of acibenzolar-S-methyl, which was equal to the efficacy of standard bactericide treatment. This compound therefore offers a very good alternative to conventional chemicals used for controlling bacterial diseases in beans.
