Changes in the content of chlorophyll in leaves when using pesticides and microfertilizers

Abstract

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.

Physiology and Development of Soybean under Light Supplementation Treated with Herbicides in the Field

“…Chlorophylls a and b are green pigments present in plant cells and indicators of the intensity of photosynthesis [35] (Roca et al, 2024). The amount of pigments is related to the plant organism's reaction to growth conditions, such as the presence of herbicides [36] ( Zheryakov et al, 2021).…”

Effect of Pesticides on Crop, Soil Microbial Flora and Determination of Pesticide Residue in Agricultural Produce: A Review

“…According to Zheryakov and I Zheryakova, [36] When herbicides were treated with microfertilizers, the amount of chlorophyll a and b pigments was 4% greater and in contrast, the chlorophyll content of the leaves was 0.350% by weight. Inhibitory effect of dimethoate was observed by Mishra et al [37] in which dimethoate inhibited photosynthetic reaction by acting on PSII.…”
