dc.descriptionIn many tropical and subtropical nations, papaya production is further hampered by papaya ring spot virus, which also causes significant crop losses. Insecticide treatments are not successful due to the mode of transmission of the virus. The objective was to identify ring spot (PRSV) problems in papaya (Carica papaya L.) crops. This document, which has a practical component, will be created by collecting all types of information through research on the different websites, academic works, sources and bibliographic databases available on digital platforms. The findings establish that the symptoms of PRSV-P infection, which were evaluated in this study in greenhouse and field environments, include vein clearance, blade bladder formation, leaf blade loss with only exposed veins, distortion of the blades and petioles, spots on stem and fruits, and plant dwarfism, produces filiform leaves, blisters, thinning of veins, frog legs, mosaic symptoms and systemic chlorosis in indicator plants of Carica papaya "papaya" ; The prevention of aphids with an entomological canopy to the papaya seedbed and the establishment of a barrier with yellow polyethylene plastic and tall grass before transplanting a sprayed insecticide caused late infection of the plants; Similar cases of management decreased the incidence of PRSV. It is considered the main method to control this disease in plants.es_ES

dc.description.abstractEn muchas naciones tropicales y subtropicales, la producción de papaya se ve más obstaculizada por el virus de la mancha anular de la papaya, que también causa importantes pérdidas en las cosechas. Los tratamientos con insecticidas no tienen éxito debido al modo de transmisión del virus. El objetivo era identificar problemas de mancha anular (PRSV) en el cultivo de papaya (Carica papaya L.). Este documento, que tiene un componente práctico, se creará recopilando todo tipo de información a través de investigaciones en los distintos sitios web, trabajos académicos, fuentes y bases de datos bibliográficas disponibles en plataformas digitales. Los hallazgos establecen que los síntomas de la infección por PRSV-P, que se evaluaron en este estudio en ambientes de invernadero y de campo, incluyen aclaramiento de las venas, formación de vejiga en el limbo, pérdida de la lámina de la hoja con solo las venas expuestas, distorsión de las láminas y pecíolos, manchas en tallo y frutos, y enanismo vegetal, produce hojas filiformes, ampollas, adelgazamiento de venas, ancas de rana, síntomas de mosaico y clorosis sistémica en plantas indicadoras de Carica papaya "papaya"; La prevención de pulgones con toldo entomológico al semillero de papaya y el establecimiento de una barrera con plástico de polietileno amarillo y pasto alto antes del trasplante de un insecticida rociado provocaron infección tardía de las plantas; casos similares de manejo disminuyeron la incidencia de PRSV. Se considera el método principal para controlar esta enfermedad en las plantas.es_ES
