It was studied an opportunity of common application of herbicide certo plus, WDG in a mixture with retardant chlormechvatchloride 460 BASF, insecticide decis, CE, nitrogen fertilizer CAS in sowings of a spring wheat variety Banty. During research it was established that the given mixtures are physico-chemical compatible and do not render fitotoxic influence on protected crop. Overlapping of chemical weeding with application retardants, insecticides and nitrogen fertilizers as 2-3 componential mixtures reduced number and weight of weeds in 1,1-1,3 times and to increase in productivity of crop on 7,4-13,1 c/ha. Complex use of pesticides allowed to increase economic and power production of grain of a spring wheat. So, the net return and profitability of production of a grain at application of the given mixtures increased in comparison with application of the minimal dose of this herbicide in the pure state (0,1 kg/ha) on 16,09-57,53 $/ha and 3,4-11,4% accordingly. Complex application of herbicide, growth regulator and nitrogen fertilizer increased a recoupment of power inputs on 0,2. In conditions of market economy the cost estimation of each technological method has a great value. However at disparity of prices for more objective estimation it is expedient to supplement the economic analysis of the received results by energetic ones. A generalizing parameter of the given estimation is the factor of energetic efficiency which reflects a recoupment of power expenditures. In a control variant it has made 2,3, spraying by herbicide certo plus has raised it up to 2,8
