One of the ways to reduce the phytotoxicity of herbicides on cultivated plants is the use of trace element fertilizers. The article presents the results of research on the influence of liquid trace element fertilizers on the content of chlorophyll in leaves and the productivity of sugar beet. It was found that three days after the treatment of crops with herbicides together with microfertilizers, the amount of chlorophyll a and b pigments was 4% higher than when applying herbicides without microfertilizers. In the control version, where pesticides and microfertilizers were not applied, the content of chlorophyll in the leaves was 0.350% by weight. As the observations showed, the photosynthetic activity of sugar beet plants was restored 4-5 days after the treatment by herbicides. Herbicides, with the simultaneous introduction of micro-fertilizers, had a less negative effect on the photosynthesis of sugar beet than herbicides alone. The biological yield of root crops in the variant with the combined use of pesticides and microfertilizers was 56.36 t/ha. The polarization of sugar beet root crops with the combined use of pesticides and microfertilizers was 0.64% higher than in the variant without microfertilizers.
