Abstract
El presente trabajo de investigación se realizó en Huaca Blanca Alta, situado a 192 m.s.n.m, con coordenadas UTM 683195 Este y 9210199 Norte en el distrito de Chepén, provincia de Chepén, región de La Libertad. El objetivo fue determinar la eficacia de dos insecticidas ecológicos en el control de Thrips tabaci L. en Allium cepa L. Var. Camaneja en Chepén La Libertad; los tratamientos en estudio fueron T0 (testigo); T1 (20 mL de CROPS CANELA /20 L de agua); T2 (30 mL de CROPS CANELA /20 L); T3: 50 mL de NIMBIOL 0/20 L de agua y T4: T3: 60 mL de NIMBIOL/20 L de agua. Se empleó el diseño estadístico de bloques completos al Azar (DBCA) con 04 tratamientos más un testigo y 04 repeticiones. La variabilidad de los datos se determinó con el análisis de varianza y la diferencia estadística entre tratamientos con la prueba de Duncan (α = 0.05). Las variables evaluadas fueron: Número de Thrips tabaci L vivos/planta; porcentaje de infestación, rendimiento y relación beneficio-costo. Los resultados indicaron que la mayor efectividad para el número del Thrips tabaci vivos/planta, en las siete aplicaciones, se obtuvieron con los tratamientos T4 y T2; respecto al rendimiento el mejor resultado lo obtuvo el T4: 41.9750 t/ha, seguido del T2: 41.3250 t/ha; y en la relación beneficio-costo con el T4 fue 1.98, mientras que el T2 obtuvo 1.95
ABSTRACT The present research work was carried out in the Huaca Blanca Alta Urban Zone, located at 192 meters above sea level, with UTM coordinates 683195 East and 9210199 North in the district of Chepén, province of Chepén, region of La Libertad. The objective was to determine the effectiveness of two ecological insecticides in the control of Thrips tabaci L. in Allium cepa L. Var. Camaneja in Chepén La Libertad; The study treatments were T0 (control); T1 (20 mL of CROPS CINNAMON /20 L of water); T2 (30 mL of CROPS CINNAMON /20 L); T3: 50 mL of NIMBIOL/20 L of water and T4: T3: 60 mL of NIMBIOL/20 L of water. The statistical design of randomized complete blocks (DBCA) was used with 04 treatments plus a control and 04 repetitions. The variability of the data was determined with the analysis of variance and the statistical difference between treatments with the Duncan test (α = 0.05). The variables evaluated were: Number of live Thrips tabaci L/plant; infestation percentage, yield and benefit-cost ratio. The results indicated that the greatest effectiveness for the number of live Thrips tabaci/plant, in the seven applications, was obtained with treatments T4 and T2; Regarding yield, the best result was obtained by T4: 41.9750 t/ha, followed by T2: 41.3250 t/ha; and in the benefit-cost relationship with T4 it was 1.98, while T2 obtained 1.95
