    (2023-03) Tuasa Choco, Ángel Paul; Pallo Paredes, Edwin Leonardo
    The aim of this study was to evaluate different ways of disinfection of potato tuberseed (Solanum tuberosum var. Superchola) in the towns of Montalvo and Tamboloma in the Tungurahua-Ecuador province. In this investigation, two forms of disinfection (Immersion and Spray) were evaluated at different times (Start of collection and prior to sowing) compared with two controls (absolute and farmer). For this purpose, a Random Block Design (R.B.D.) was used with a 22 + 2 factorial arrangement in three repetitions using the "Amistar Top" product. The best results for the number, length and diameter of shoots were achieved with the application of T1 (immersion at the beginning of the collection). Regarding the days to sprouting and weight differences, the T0 and Ta treatments presented better results. Regarding the number of true stems, a better result was obtained after the application of T1. Finally, a greater presence of pathogens was found in the tubers without disinfection for the two locations.
