Abstract

Processing potatoes with water extract from the amaranth of Early splendor variety leads to an increase in the parameter (FM – FT)/FT of slow induction of leaf fluorescence up to 51%. At the same time, the effectiveness of restricting the nutrition of larvae of the Colorado potato beetle on the treated plants reaches a maximum of 64%. Laboratory experiments show a decrease in larval survival on treated plants. Due to its dual properties as a biostimulant and insecticide, as well as low toxicity to vertebrates, amaranth extracts can be recommended for integrated pest management programs.
