Economic efficiency of application of tank mixes of herbicides on corn

The article presents the results of three years of research on the effectiveness of herbicides and their mixtures on maize crops in the Rostov region. The scheme of experiment included 7 variants of herbicides from different chemical classes and their mixtures, as well as control (without herbicides). Calculation of economic efficiency showed that the highest conditional net income (12845 rubles. 1 ha with a payback of 11.1 rubles per 1 ruble invested in protective measures noted at the time of application on corn the tank mixture of Arpad + Esteron, given the size of the stored crop and processing on this variant. Slightly lower (10761 and 10082 RUB/ha) in the variants with application of a tank mixture of Milagro with Banuelos and Callisto, respectively.
