The aim of this work is to define the phytotoxicity and efficiency of dicamba based herbicides (preparation DICAMBA 480 SL) and possiblity of its application for foliar suppression of broadleaf weeds in the corn crops. During 2011, on the location of Zemun Polje is examined efficiency of this preparation through carrying out of field experiments in accordance with the standard EPPO methods. Trial has been carried out on the soil type chernozem. The experiment included 4 treatments: two for efficact (DICAMBA 480 SL 0,5 and 0,7 l/ha), one for phytotoxicity (DICAMBA 480 SL 1,4 l/ha) and one as the standard (PLAMEN 0,7 l/ha). Preparation is applied foliary, when the corn used to have 4-5 leafs, and weeds 2-5 lefs. Dicamba as selective systemic hormonal herbicide from chemical group of the derivates of benzoic acid does not manifest phytotoxicity towards corn, if applied in recommended quantities and within recommended application time. Results of these experiments denoted good efficiency of dicamba (preparation DICAMBA 480 SL).
