Estimation of the aftereffect of autumn pesticide treatment of seed tubers on vegetating potato
The article presents experimental data on the aftereffect of autumn seed potato treatment with chemical and biological preparations on growth, development, plant infestation with rhizoctoniosis, and yield. The experiments were conducted in the Lyuberetsky district of the Moscow region in 2018-2019. Chemical preparations Kagatnik, Maxim, biological-Kartofin, micronutrient Siliplant, as well as their combined use, were estimated. Research data show that the autumn treatment of potato tubers of the Nadezhda variety with the studied preparations allowed to reduce the percentage of plants affected by rhizoctoniosis by 2.3-17.0% compared to the control. The increase in yield from the use of chemical preparations was from 21.7 to 37.5%, biological-by 7.2-12.1% compared to the control.
