Abstract
El objetivo de este trabajo de investigación fue evaluar el control de Pseudococcus spp. con aceites y extractos vegetales en Vaccinium corymbosum var. Biloxi en Chao La Libertad, utilizando plantas de tres años de edad con manejo orgánico. Se evaluaron cinco tratamientos: Extracto de Ají Habanero 5 litros /cil (T1), Prophyt Acaros 0.6 litros /cil (T2), Crops Titan 0.6 litros/cil (T3), Nim 700 0.6 litros/cil (T4), Golden Natural Oil 4 litros/cil (T5) y un tratamiento testigo sin aplicación (T0), los tratamientos fueron distribuidos bajo un diseño de bloques completos al azar, con tres repeticiones, las aplicaciones se realizaron con mochila a palanca Jacto empleando un volumen de 800 litros/ha mas 0.2 litros /cil de ácido sulfuroso como acidificante. Las variables evaluadas fueron infestación (I) y grado de infestación (GI) de la plaga, para las evaluaciones se tomó al azar de cada unidad experimental 5 plantas por tratamiento las cuales fueron marcadas para realizar todas las evaluaciones. El tratamiento que obtuvo el mejor efecto fue Golden Natural Oil en dosis de 4 litros por hectárea (T5), que redujo la incidencia de Pseudococcus spp de 73.3 a 33.33% y la severidad de la infestación de 68.7 a 35 ninfas y de 5 a 1.3 (adultos) por planta.
ABSTRACT The aim of this work of investigation was to evaluate the control of Pseudococcus spp. with oils and vegetable extracts in Vaccinium corymbosum var. Biloxi in Chao, La Libertad, using plants of three years of age with organic managing. Five treatments were evaluated: Extract of Of Havana Chili 5 liters/cil (T1), Prophyt Acaros 0.6 liters/cil (T2), Crops Titan 0.6 litros/cil (T3), Nim 700 0.6 litros/cil (T4), Golden Natural Oil 4 litros/cil (T5 and one treatment witness without application (T0), the treatments were distributed under a design of complete blocks at random, with three repetitions, The applications were realized by rucksack to lever I boast using a volume of 800 litros/ha mas 0.2 liters/cil of sulphurous acid as acidificante. The evaluated variables were an infestation (I) and degree of infestation (GI) of the plague, for the evaluations one took at random of every experimental unit 5 plants for treatment which were marked to realize all the evaluations. The treatment that obtained the best effect was Golden Natural Oil in dose of 4 liters for hectare (T5), which reduced the incident of Pseudococcus spp from 73.3 to 33.33 % and the severity of the infestation from 68.7 to 35 nymphs and from 5 to 1.3 (adults) for plant.
