The increase in the phytotoxicity of herbicides on monocotyledonous and dicotyledonous crops when they are used at the same time with insecticides — monooxygenase inhibitors (class of organophosphorus compounds) has been studied. The effect of dimethoate on the phytotoxicity of the main graminicides used in crop production in Ukraine was determined, and the impact of magnesium on the effect of the pesticide composition was determined. It was found that dimethoate in compositions with graminicides of the class of acetyl-CoA-carboxylase inhibitors can cause an increase in phytotoxicity of xenobiotics to cereals (pinoxaden to winter wheat) and dicotyledonous crops (fluazifopbutyl to pea). The negative effect of xenobiotics on crops can be reduced by using magnesium sulfate in formulations with pesticides. Taking into account the established effect of magnesium and sulfur on increasing the efficiency of nitrogen use and the formation of crops with increased heat resistance, the use of magnesium sulfate in doses of 2 kg/ha in formulations with herbicides (graminicides and dicotyledonous preparation) and insecticides is important for increasing the efficiency of weed and pest control and for the formation of sustainable profitable crop production.
