Abstract:
Papaya ring spot disease, caused by the Papaya ring spot virus (PRSV), is a major limiting factor in papaya cultivation in the Marathwada region of Maharashtra, it has potential to cause up to 100% yield loss. The present study aimed to investigate the effect of eleven bioagents viz., Trichoderma asperellum, Trichoderma harzianum, Verticillium lecanii, Bacillus subtilis, Pseudomonas fluorescens, PPMF, Streptomyces californicus, Metarhizium anisopliae, Beauveria bassiana, Biomix and an untreated control, in inducing resistance against PRSV under greenhouse conditions.

Abstract:
In the midst of the rising interest of papaya cultivation in Kerala, it is inevitable to study the current status of the Papaya ring spot disease in the state. Knowing the severity and distribution of PRSV isolates, causing ring spot disease, helps in the better formulation of effective management strategies against it. Purposive sampling surveys carried out in 2021-22 across five agro ecological units (AEUs) of Kerala, recorded papaya ring spot disease incidence (PRSD) ranging from 50 to 100 per cent in the cultivated areas with vulnerability index of 33.54 to 98.22. Highest disease incidence

The morphological symptoms induced are ring spot, distortion and mottling symptoms on foliage, stunting in stem, fragile roots and concentric ring and deteriorated fruit. The anatomical studies of 90 days old symptomatic leaf stem and root sample revealed extensive deformation of parenchyma tissues in leaf, poor differentiation of vascular tissue without disintegration, reduced size of xylem cells in roots. The root tissues also showed increased lignifications and reduced protoxylem. Hyperplasia in cells exter

A total 15 front line demonstrations for virus disease management in papaya were conducted for three years from 2021-2022 to 2023-2024 at farmer’s field, Nellore district of Andhra Pradesh. The higher incidence of papaya ring spot virus disease was observed during 2022-23 (50.2%) followed by 2021-22 (43.6%) in farmer practice over the demonstration.

Abstract:
Papaya Ring Spot virus (PRSV) is a devastating viral disease in papaya cultivation in Sri Lanka. It was reported that mountain papaya (Vasconcellea cundinamarcensis) exhibits resistance to PRSV. Therefore, this study was conducted to evaluate the potential resistance to PRSV in mountain papaya to be used in papaya improvement breeding programs. Carica papaya and V. Cundinamarcensis were inoculated with PRSV by mechanical inoculation technique and symptoms were evaluated visually. In order to detect the latent infection, a molecular method was developed.

Papaya (Carica papaya L.) is an important fruit crop in Bangladesh. During surveys conducted in Dhaka and Mymensingh regions from April to June 2003, >50% of papaya plants were observed to have leaf mottling, mosaic and mild distortion, and water-soaked streaks on petioles and stem, which are typical symptoms of Papaya ring spot virus (PRSV) infection. Electron-microscopic examination of negatively stained leaf-dip preparations from 10 symptomatic samples revealed the association of flexuous virus particles that were decorated with polyclonal antibodies raised to an isolate from India (PRSV

This chapter examines the controversies that surround the introduction of transgenic papaya on Hawaii Island, in the wake of the devastation caused by the ring spot virus in the 1990s. It critically examines the respective positions of industry proponents and anti-GM activists, and cautions against the tendency of essentializing GM papayas as either a savior or harbinger of destruction. While both positions raise valid underlying concerns, they both tend to overlook the more difficult challenges of managing smallholder papaya industry in a global market.
