Abstractdc.description.abstractDurante la temporada 2013-2014 se estudió el efecto de la aplicación de aceite mineral (Purespray 15E) y aceite vegetal (Protek) sobre la incidencia de la mancha anular marrón producida por el Trips de California, Frankliniella occidentalis Pergande, en uva de mesa variedad Thompson seedless durante el periodo de cierre de racimo. Se realizó un ensayo en un huerto comercial ubicado en la comuna de Buin, Región Metropolitana, en el que se evaluó tratamientos de aceites mineral y vegetal con diferentes concentraciones y número de inmersiones. Para el ensayo se seleccionaron racimos sanos y homogéneos de 150 bayas aproximadamente, los que se sumergieron en cada tratamiento durante 5 segundos. Posteriormente se infestaron con 50 adultos de Trips de California y fueron encerrados en bolsas de tul; transcurrida una semana se realizó una segunda inmersión en los tratamientos que correspondía y se repitió la infestación en las unidades experimentales. Los racimos se encerraron nuevamente en bolsas de tul hasta la evaluación. La evaluación se realizó en periodo de cosecha, considerando el porcentaje de bayas que presentaban daño por Trips de California, caracterizado como mancha anular marrón. Se empleó un diseño de bloques completamente aleatorizados con 10 tratamientos y 8 repeticiones, siendo la unidad experimental un racimo. Se consideró cada planta como un bloque independiente. Los resultados se normalizaron mediante la transformación angular de Bliss. Posteriormente se sometieron a un análisis de varianza y prueba de comparaciones múltiples DGC. Los tratamientos de Aceite Mineral (Purespray 15E) al 0.5% y al 0.75% reducen efectivamente el daño causado por F. occidentalis durante el periodo de cierre de racimo. Los tratamientos con Aceite Vegetal (Protek) al 0.5% y al 0,75% reducen parcialmente el daño causado por F. occidentalis durante el periodo de cierre de racimo.es_ES
Abstractdc.description.abstractDuring the 2013-2014 season, the effect of the application of mineral oil (Purespray 15E) and vegetable oil (Protek) on the incidence of brown ringspot caused by the Western Flower Thrips (Frankliniella occidentalis Pergande) on table grape was studied, focusing on the Thompson seedless variety during cluster closing time. Trials were conducted in a commercial orchard located in the commune of Buin, Metropolitan Region, treatments mineral and vegetable oils with different concentrations and number of dives were evaluated. For the test, healthy and homogeneous clusters of approximately 150 berries were selected, and immersed in each treatment for 5 seconds. Then, they were infested with 50 adults of Western Flower Thrips and locked in tulle bags; after a week, a second application was performed of the corresponding treatments and the infestation was repeated in all experimental units. The clusters were again locked in tulle bags until evaluation. The evaluation was conducted in harvest period, considering the percentage of berries that showed damage from Western Flower Thrips, characterized as brown ringspot. Design of completely randomized blocks of 10 treatments and 8 repetitions were used. The experimental unit being a cluster. Each plant is considered as a separate block. The results were normalized by Bliss' angular transformation. Subsequently, they were subjected to a variance analysis and DGC multiple comparisons tests. Treatments with Mineral Oil (Pure Spray 15E) at 0.5% and 0.75% effectively reduce the damage caused by F. occidentalis during cluster closing time. Vegetable oil treatments (Protek) at 0.5% and 0.75% only partially reduced the damage caused by F. occidentalis during the cluster closing.es_ES
