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.

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.

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.

The cultivation of papaya for both fruits and commercial papain extraction drastically suffers often due to the devastating incidence of papaya ringspot virus disease. The present study aimed to find out whether the papain yield and quality are influenced when bioregulators are applied to manage papaya ring spot virus (PRSV) incidence or as a measure to limit the height of the crop in TNAU Papaya CO.8 variety grown in the open field with the natural incidence of PRSV. Three growth retardants [250 ppm of prohexadione calcium (G2), 500 ppm of mepiquat chloride (G3) and 500 ppm of chlormequat chl

Plants have a variety of uses, especially in medicinal aspects, they have phytochemicals which have effects on the human body. People in rural areas used the decoction method and mechanical pounding method in preparing the plant extracts. People usually choose not to go to drugstores to purchase drugs, which sometimes is costly. This experimental study aimed to determine the effects of fresh young papaya leaf extracts of different varieties on the platelet count of white mice. In this study, C. papaya, commonly known as the papaya plant, was extracted through a mechanical or pounding method an

Greenhouse-grown cucurbit crops in several Iranian regions were surveyed for the incidence of Cucumber mosaic virus (CMV), Squash mosaic virus (SqMV), Papaya ring spot virus-type W (PRSV-W), Watermelon mosaic virus-2 (WMV-2), Zucchini yellow mosaic virus (ZYMV), Cucumber necrosis virus (CuNV) and Tomato spotted wilt virus (TSWV) from September 2002 to June 2004. In all, 1,304 random and 1,085 symptomatic leaf or fruit samples were collected. Samples were analyzed for virus infection by enzyme-linked immunosorbent assay. CMV and ZYMV were the viruses most frequently detected, accounting for 21.

In December 2002, bottlegourd (Lagenaria siceraria L.) plants grown as a commercial crop in Pune, India (western Maharashtra) showed severe mosaic, interveinal chlorosis, and leaf deformation that resulted in fern-leaf appearance and severe fruit distortion in approximately 70% of the plants. Crude sap of collected samples was used to mechanically inoculate uninfected glasshouse-grown bottlegourd plants that reproduced symptoms observed in the field. Sap extracts from these glasshouse infected bottlegourd plants were used to mechanically inoculate selected indicator hosts. Chlorotic local lesi

Silicon is crucial in the process of absorbing and transporting nutrients to the plants, which in turn helps to decrease the toxicity of iron (Fe), aluminium (Al), and manganese (Mn). Plants can better endure drought and salt stress because it strengthens their tissues. Seaweed extracts serve as biostimulants and are considered vital nutrients for sustainable agriculture due to their organic nature and ability to decompose naturally. The present study aimed to compare the nutritional content and growth rate of papaya cv. Red Lady after being treated with silicon and seaweed extract. The papaya

Papaya is one of the most important fruit crops of tropical and subtropical regions of the world including India. Though India stands first in production in the world, the productivity is low as compared to other countries due to high incidence of papaya ring spot virus (PRSV-P) attack. As all the cultivated varieties under genus Carica are susceptible to PRSV, investigations were carried out to evaluate fifteen intergeneric hybrid progenies of Arka Prabhath x V. cauliflora and eighty-five progenies of Arka Prabhath x V. cundinamarcencis for morphological, fruit and yield traits coupled with P

Bitter gourd mosaic complex (BGMC) is caused by multiple viruses in bitter gourd which seriously affects the crop performance and leads to complete crop loss. Bitter gourd is widely cultivated in Kerala as the market price is steady throughout the year. BGMC is the most important production constraint as most of the high yielding varieties including hybrids are severely affected by the virus complex. The study assessed the prevalence of BGMC in major bitter gourd cultivating agro-ecological units (AEUs) of Kerala and detected the viruses associated. It was found that, the disease incidence (DI

Abstract Bangladesh is on the verge of adopting genetically modified (GM) crops for commercial cultivation and consumption as feed and food. Most of the laboratories are engaged in tissue culture and molecular characterization on plants, whereas some have started living modified organism research with shortages of trained manpower, infrastructure, and funding. Nutritionally improved Golden Rice, biotech brinjal, and late blight-resistant potato are in contained trials in a greenhouse, and potato ring spot virus-resistant papaya is in the process of approval for a field trial.
