PVY is distributed worldwide in potato growing areas, tobacco growing areas and outdoor crops of tomato and pepper in warm countries. The different strains of PVY develops different symptoms on different parts of the host plant species. The PVY have a host range of 495 species in 72 genera of 31...

Taxonomy: Iris yellow spot virus (IYSV) is in the genus Tospovirus, family Bunyaviridae, with a single-stranded, tri-segmented RNA genome with an ambisense genome organization. Members of the other genera in the family infect predominantly vertebrates and insects. Geographical distribution: IYSV is ...

Cotton leaf curl virus (CLCuV) disease is crucial threat for cotton production in Pakistan. CLCuV belongs to genus Begomovirus of Geminiviridae family and is transmitted by Bemisia tabaci. Drastic reduction in yield was observed during 1994-95 and 2007-08 due to this disease. However in 1996-1997...

Rice (Oryza sativa L.) is cultivated in more than 100 countries and supports nearly half of the world's population. Developing efficient methods to control rice viruses is thus an urgent necessity because viruses cause serious losses in rice yield. Most rice viruses are transmitted by insect...

Processing tomatoes (Solanum lycopersicum) are an important industry in the Dominican Republic. In November 2012, symptoms typical of tospovirus infection (bronzing, chlorosis, and necrosis of leaves) appeared in numerous processing tomato fields in the North (>50% incidence in some fields) and...

Maize provides an important source of forage for the maize-dairy farmers in Kenya. However, due to small farm size, maize cannot supply all the feed needed for dairy cattle and forage is in short supply in the dry seasons. This paper examines practices to increase the health and use of maize and...

Plum pox virus (PPV) has been observed in Turkey since 1968, but was not widespread except in apricot and plum trees in home gardens and ornamental parks in restricted areas. Susceptibility of six different Prunus rootstocks to strain PPV-T was assessed under natural inoculum pressure in the...

Compared to other vegetable crops, the major viral constraints affecting pepper crops in the Mediterranean basin have been remarkably stable for the past 20 years. Among these viruses, the most prevalent ones are the seed-transmitted tobamoviruses; the aphid-transmitted Potato virus Y and Tobacco...

Potyviridae causes substantial yield losses in watermelon, pumpkin, zucchini, melon and squash, and are the most frequent family of viruses reported in cucurbits in Puerto Rico. Sampling conducted between 2006 and 2011 showed that PRSV (Papaya ringspot virus) and ZYMV (Zucchini yellow mosaic virus...

Spotted wilt disease of peanut (Arachis hypogaea) (SWP), caused by Tomato spotted wilt virus (TSWV) (genus Tospovirus, family Bunyaviridae), was first observed in Alabama, Florida, and Georgia in the late 1980s and rapidly became a major limiting factor for peanut production in the region. Tobacco...
