Herbicide resistance systems that combine application of chloroacetamides and triazines (before sowing) and of semicarbazone and pyrazolone derivatives and benzoic acid (following the seedling stage) have been proven to have high technical effectiveness. The elaborated approach contributes to gathering in 6 to 8 tons of grain per hectare and making 16-17 thousand UAH of profit per hectare. A combined technological grain crop re-infestation control system was tested based on the use of energy (phytocenotic) potential of hybrids of intensive type (narrowing of the row spacing from 70 cm to 45 cm) and application of Stellar postemergence herbicide (1.25 L/ha) + Metolat surfactant (1.25 L/ha) comprising such active ingredients as topramezon (50 g/L) and dicamba (160 g/L). This innovation makes it possible to improve the ecological status of the environment by eliminating soil chemicals and increase profitability from 93 to 122%. Methods of control of pest heterogeneous populations in non-fallow winter wheat crops have been proposed, which are based on the application of universal tank mixtures containing two-component herbicides, insectoacaricides and systemic broad-spectrum fungicides, which provide an increase in grain yield by 1.45-1.66 t/ha and a decrease in its cost by 1110-1309 UAH/t.
