Abstract
In article results on influence of insecticides on biochemical structure of tubers of potatoes are presented. The laboratory analysis of tubers of potatoes, treated by insecticides, on the contents of dry substance, starch, nitrates, and vitamin C is spent. Three insecticides were tested: Clorid v.k. (0.07 l/ha), Insect (0.1 l/ha), Amadeus (0.08 l/ha). Research experiments were conducted on the fields of "Kokshetau Experimental Production Farm" LLP, Akmola Region, Zerenda District. The research was carried out on potato crop, varieties "Shagalaly" and "Galla". According to the results of the analysis of potato tubers the abovementioned insecticides used to control the Colorado potato beetle do not have a significant effect on the biochemical composition of tubers. The highest vitamin C content was observed in the variant with the insecticide Amadeus (0.08 l/ha) - 14.9% and in the variant with the insecticide Klorid v.k. (0.07 l/ha) - 14.5%. At laboratory research of structure of samples of tubers of potatoes, the maintenance of dry substance in a control variant was 22,6 %. The starch content in the variant treated with insecticide Klorid v.k. (0.07 l/ha) showed the highest result and amounted to 15.8%.
