Within the period 2011-2014, at the experimental base of the Agricultural University – Plovdiv we conducted field experiments with new herbicides in wheat. Based on the obtained results, we made a summarized economic assessment of the chemical fight against weeds. We established the amount of production expenses needed for growing wheat in 10 tested variants including 9 treated with herbicidal preparations. It was found the critical levels of the yield for each variant as well as the factors determining them. The economic effectiveness of production has been analyzed using a system of various indicators: the value of the permanent and variable costs per unit of area; the level of the average yield; the value of the total revenue per unit of area; the amount of the profit from 1 ha; the prime cost of the production and the profitability rate. The highest average yield was obtained from the variants treated with herbicides: Axial 1 plus 050 EK (5180.60 kg/ha); Sekator OD (5200.00 kg/ha) and Pasifica VG (5210, 46 kg/ha). Upon the application of these herbicides, the rate of increase of the additional production from unit of area exceeds the rates of the investments made. This makes the use of these herbicides economically substantiated. With the exception of the untreated control sample, all other herbicides give good economic results from the production of wheat, a sufficient profit rate from unit of area and profitability ranging from 20% to 22%.
