Resumen
El experimento se ejecutó en los predios de la Empresa “Palmar Del Río” ubicada en la provincia Francisco de Orellana, cantón Coca, vía Huachito, recinto Huachito. Los objetivos fueron: 1) Evaluar la acción del insecticida pleo 50 EC sobre el control de Sagalassa valida W. 2) Determinar la mejor dosis del insecticida nakar para combatir S. valida y 3) Conocer el costo de los tratamientos estudiados.
Se obtuvo como conclusiones: 1) Que el tratamiento 5 (pleo), comparado con los demás tratamientos estudiados presentó estadísticamente el mayor control en porcentaje de raíces con daño fresco, al igual que en las demás variables como: número de raíces funcionales, nuevas, con daño fresco y con daño viejo ocasionados por el ataque del insecto plaga Sagalassa valida Walker aunque fueron diferencias numéricas, en general la mayoría de los tratamientos evaluados presentaron buenos números similares de raíces funcionales y nuevas al igual que en su emisión foliar que obtuvieron un promedio de 2 hojas/mes 2) En el estudio de la mejor dosis del ingrediente activo benfuracarb “nakar” fue el tratamiento 3 (nakar 1.5) el cual registró mejor control en el ataque de este insecto por su mayor dosis que el tratamiento 2 (nakar 1.0) por su dosis más baja. 3) En el costo de los tratamientos estudiados, registra como más factible al tratamiento 6 “terbufos” por su bajo costo de USD 318.12 resaltando que fue retirado del mercado por su alta toxicidad, pero fue dominado por el tratamiento por el tratamiento 5 “pleo” en las demás variables evaluadas, pero con un valor de USD 693.98, que comparándolos es el doble de su costo.
The experiment was carried out in the premises of the company “Palmar Del Rio” located in the Francisco de Orellana, Coca canton via Huachito campus Huachito province. The objectives were: 1) To evaluate the insecticide pleo 50 EC on the control of Sagalassa validates W. 2) To determine the best dose of insecticide to combat S. nakar validates and 3) Know the cost of the treatments. Was obtained as conclusions: 1) the treatment 5 (Pleo), compared to other treatments studied statistically presented greater control in percentage of roots with fresh damage, as well as other variables such as number of functional roots, new, fresh damage and old damage caused by the insect pest attack Walker Sagalassa valid although numerical differences were generally most evaluated treatments had similar good numbers of functional and new roots as in the foliar emission averaged a 2 sheets / month 2) In the study of the best dose of the active ingredient Benfuracarb "nakar" was treatment 3 (nakar 1.5) which reported better control of this insect attack because of its greater dose treatment 2 (nakar 1.0) by its lower dose. 3) the cost of the treatments studied, recorded as more feasible to treatment 6 "terbufos" for its low cost of USD 318.12 noting that it was taken off the market because of its high toxicity, but was dominated by treatment by treatment 5 "pleo "in the other variables assessed, but with a value of USD 693.98, which is twice comparing its cost.
