Efficiency of Treatment of Tubers Against Pests and Diseases of Potatoes in the Amur Region

Abstract

AbstractThe need for research is due to the high demand for potato products among the population of the region and its significant losses during cultivation. The experiment was carried out in 2018–2019 at the experimental site of the Federal State Unitary Enterprise (FSUE) «Sadovoye» of the Amur Region. The soil is meadow chernozem-like soil. In 2018, the summer was warm and humid; in 2019, it was cold and excessively humid. Studied options for experience are given 2–5 in the tables. The degree of damage leaves, eaten by pests or covered with the disease, was determined. The degree of prevalence was determined by inspection on 10 plants. Damage to plants by the 28-spotted ladybug was lower than in the control variant by 11.6% in the second variant, 71.8% in the third variant, 45.3% in the fourth variant, 84.5% in the fifth variant, and 81.2% in the sixth variant. The degree of disease damage, respectively options, decreases by 25.4, 50.4, 34.2, 51.8, 52.1%, and their prevalence by 6.8, 21, 13.3, 26.2, and 25.5% compared with the control. The greatest increase in the yield of potato tubers is provided by preparations Prestizh, KS – 11.3 t/ha, Kruyzer, KS – 12.5 and Maksim, KS + Kruyzer, KS – 14.9 t/ha. The economic efficiency of these preparations reached 50.4, 57.6, and 74.6%. Preparations Prestizh, KS, and Kruyzer, KS can be recommended for the integrated protection of potato plants during the growing season from diseases and pests in the Amur region.KeywordsAgricultureEnvironmental studyTubersPotatoesPests
