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.

The Colorado potato beetle is a serious pest of Solanaceae crops in our country, especially potatoes. In order to reduce the chemical load in the field and prevent the development of resistance to chemicals in the Colorado beetle, this paper presents biological methods of protection using seasonal colonization by the predatory shield bug Picromerus and treatments with plant extract of amaranth of the Valentine variety (which, along with limiting the nutrition of the larvae of the Colorado beetle, stimulates growth and leads to an increase in the photosynthetic activity of protected plants). Additional treatment with amaranth extracts is recommended during the flowering period, which is critical for potatoes. Damage to potato leaves by Colorado potato larvae during this period can lead to significant decrease in productivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
