Validación de una estrategia en el control de tizón tardío (Phytophthora infestans) en papa (Solanum tuberosum L.) con las variedades INIAP-libertad, INIAP-cecilia y superchola, en la provincia de Tungurahua
(2017) Freire Tenelema, Mayra Alejandra; Cruz Tobar, Saúl Eduardo
The following investigation seeks to validate one strategy to control Late Blight (phytophthora infestans) in potatoes (solanum tuberosum l.) in three potato types, INIAP Cecilia, Superchola, Libertad with the aid of the DSS (Decision Support System) through a frequency of application and evaluation of 8-12-15 days to ob-tain the best control strategy to cause less environmental impact. By doing the statistical analysis of the area under the disease progress curve (AUDPC) it was possible to determine that the potato type Libertad, due to its own characteristics, showed a higher resistance to Late Blight compared to the other potato types. Regarding the Environmental Impact Rating we could determine an important de-crease when applying the DSS compared to the Farmer treatment, which shows, in the case of the Cecilia potato type, a reduction of 85,89%, in Libertad potato type 97,82% and in Super chola potato type 88,87%.
