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

Abstract

The article presents the results on the effect of insecticides on the biochemical composition, potato
yield. A laboratory analysis of potato tubers treated with insecticides was carried out for the content of the
mass fraction of dry matter, the mass fraction of starch, nitrates, vitamin C. 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.
According to the results of laboratory analysis of potato tubers, the highest vitamin C content was
observed in the variant with the use of Regent insecticide (0.025 kg /ha) – 14.8% and in the variant with the
use of Break M.E. 0.05 l/ha. In the laboratory study of the composition of potato samples, the mass fraction
of dry matter in the control variant was 22.7%. The variant treated with the insecticide YUKAZ-7 k.e. was
inferior to the control variant by 0.7%. Also, the variants treated by Break m.e., Fipromax v.d.g., Regent in
terms of dry matter content were lower than the control variant by 0.3, 0.75 and 0.25%, respectively. The
content of the mass fraction of starch in the variant treated with the insecticide Fipromax v.d.g. showed the
highest result and amounted to 15.5%, exceeding the control sample by 1.3%. The variant treated with
Regent insecticide was 15.3%. In terms of economic efficiency, the insecticide Fipromax v.d.g. distinguished
itself – the yield was 25.8 t/ha.
