THE EFFECT OF INSECTICIDES ON THE YIELD AND BIOCHEMICAL COMPOSITION OF POTATO TUBERS IN THE CONDITIONS OF THE AKMOLA

Abstract

The article presents the results of laboratory analysis of potato tubers treated with insecticides for the content of toxic elements: Pb, Cd, As, Hg. 4 insecticides were studied: YUKAZ-7, k.e. (lambda-cyhalothrin, 100 g/l); Break m.e. 0.05 l/ha; Fipromax v.d.g. (0.02-0.025 kg/ha); Regent 0.025 kg/ha.

Research experiments were placed in the scientific field of Kokshetau Experimental Production Farm LLP, Akmola region. The research was carried out on potato culture, Shagalaly variety.

Comparative studies of laboratory data analysis of potato tubers on the content of toxic elements in potato tubers showed that when treating potato plants with insecticides YUKAZ-7, k.e. (lambda-cyhalothrin, 100 g /l); Break m.e. 0.05 l / ha; Fipromax V.D.G. (0.02-0.025 kg/ha); Regent 0.025 kg/ha concentration of Pb, Cd, As, Hg was within the MPC. In terms of economic efficiency, the insecticide Fipromax v.d.g. distinguished itself - the yield was 25.8 t/ ha.
