Virus surveys of lettuce crops over the past three seasons have confirmed that a number of virus diseases can threaten production Lettuce bigvein disease (LBVD) caused by Mirafiori lettuce bigvein virus (MLBVV) usually in combination with Lettuce bigvein virus (LBVV) was the most widespread virus disease of lettuce over the survey period Other viruses present include Lettuce necrotic yellows virus (LNYV) Beet western yellows virus (BWYV) Cucumber mosaic virus (CMV) and Lettuce mosaic virus (LMV) The surveys have not detected Tomato spotted wilt virus (TSWV) or Tobacco necrosis virus (TNV) Control of Olpidium brassicae the fungal vector of LBVD is an important factor in disease management This paper outlines survey results and describes experiments using fungicides to control this disease

Lettuce (Lactuca sativa L.) is a member of the family Compositae (Asteraceae). This plant, which is grown for its leaves, is grown in open field and greenhouse conditions almost everywhere in the world and in Turkey. With the present study virus diseases of lettuce and their prevalence in Konya province was revealed for the first time. For this purpose, leaf samples were taken from lettuce plants showing virus diseases symptoms with surveys carried out in Konya province lettuce planting areas from May to August in 2020. Then the collected lettuce leaf samples were tested in laboratory conditions by Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA) method to reveal infections of Cucumber mosaic virus (CMV), Miraflori lettuce big vein virus (MiLBVV), Lettuce mosaic virus (LMV), and Tomato spotted wilt virus (TSWV). According to the information obtained from the results of the study, it was determined that 40 out of 97 (41.23%) lettuce plant samples and all (6) weed samples were infected with at least one of the viruses. In lettuce leaf samples; TSWV (27.83%), LMV (12.37%), CMV (10.31%) and MiLBVV (5.15%) infections have been detected. In weed samples; infections of CMV (83.33%), LMV (66.66%), and TSWV (50%) have been revealed. The infections of TSWV, LMV, CMV, and MiLBVV on lettuce plants in Konya province were reported firstly with the study.

AbstractThis study was conducted to determine the incidence, diversity and distribution of viruses infecting pepper (Capsicum spp.) in the central, northern and northeastern parts of Thailand. During a survey in 2016 - 2019, a total of 2,149 leaf samples from symptomatic and asymptomatic peppers were collected randomly from farmer’s fields, and preliminary tested by an enzyme-linked immunosorbent assay (ELISA) using 7 antibodies specific for cucumber mosaic virus (CMV), chilli veinal mottle virus (ChiVMV), tomato necrotic ringspot virus (TNRV), tobacco mosaic virus (TMV), potato virus Y (PVY), tomato spotted wilt virus (TSWV), and begomoviruses. Our data revealed that the incidence of the viruses infecting pepper in Thailand was high, accounting for nearly 70% (1,482 infected samples). The highest viral incidence was found in the central part (96%), followed by the north (74.4%) and the northeastern (52.8%), respectively. Begomoviruses, CMV, ChiVMV, and TNRV were detected in the samples at varying rates, whereas PVY, TMV, and TSWV were not detected. Of these, the most frequently found virus was Begomoviruses accounting for nearly 33%, with the highest rate (ca. 82%) in the central Provinces of Thailand. In addition, of the 1,482 infected samples, mixed infections among the four viruses were also found in 616 samples (ca. 42%), and CMV + ChiVMV (approximately 11%) was the most common mixed infection. This is the first report describing an occurrence of viruses in pepper of Thailand, and the results obtained have revealed that viruses infecting pepper are widespread, which may pose a threat to pepper production in Thailand.

A survey of viruses on capsicum plants in the Czech Republic was carried out in the years 2006–2010. Altogether, 375 leaf samples with symptoms suggesting viral infection were collected both from open fields and greenhouses. These samples were examined for the presence of Alfalfa mosaic virus (AMV), Broad bean wilt virus-1 (BBWV-1), Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV), Potato virus Y (PVY), Tobacco mosaic virus (TMV) and Tomato spotted wilt virus (TSWV) by ELISA. Viruses detected in the samples were AMV, BBWV-1, CMV and PVY. The most prevalent were CMV and PVY which were present in 24 and 29% of tested samples, respectively. In some cases a complex infection of two viruses was detected. Gene sources of resistance against CMV and PVY are mentioned. The relation of virus occurrence on aphid incidence is discussed.

Infeksi virus pada tanaman nilam dapat menyebabkan penurunan produksi dan kualitas minyak. Sembilan jenis virus diidentifikasi menginfeksi tanaman nilam, yaitu Patchouli mosaic virus (PatMoV), Patchouli mild mosaic virus (PatMMV), Telosma mosaic virus (TeMV), Peanut stripe virus (PStV), Patchouli yellow mosaic virus (PatYMV), Tobacco necrosis virus (TNV), Broad bean wilt virus 2 (BBWV2), Cucumber mosaic virus (CMV), dan Cymbidium mosaic virus (CymMV). Kesembilan virus tersebut memiliki genom RNA, tetapi panjang dan bentuk partikelnya berbeda. Deteksi dan identifikasi berdasarkan bagian partikel virus dapat dilakukan secara serologi dengan teknik ELISA dan secara molekuler dengan RT-PCR. Gejala awal tanaman nilam terserang virus yaitu mosaik atau belang pada daun pucuk dan pada gejala berat tanaman menjadi kerdil. Infeksi virus dapat bersifat tunggal, tetapi ada pula infeksi oleh beberapa virus. Virus menular secara mekanis dan sebagian melalui penyambungan dan vektor. TNV, BBWV2, dan CMV memiliki kisaran inang yang luas, sedangkan virus yang lain inangnya terbatas. Virus nilam umumnya memiliki titik panas inaktivasi dan titik batas pengenceran yang tinggi, sedangkan ketahanan in vitro tidak stabil. Pendekatan terbaik pengendalian virus ialah menggunakan bahan tanaman bebas virus atau tahan virus dan pengendalian vektor. Tanaman bebas virus dapat diperoleh melalui kultur meristem, sedangkan pengendalian vektor dapat menggunakan pestisida nabati atau kimia.
