The occurrence of viral co-infection is a common phenomenon in cultivated and native plant species and can alter the dynamics of virus infection. In this study, disease progress was examined in single and mixed infections of Cucumber mosaic virus (CMV) and Bean yellow mosaic virus (BYMV) by measuring the rate of symptom development, disease severity and area under disease progress curve on infe...

alfalfa crops were surveyed for the incidence of alfalfa mosaic virus (amv), cucumber mosaic virus (cmv), peanut stunt virus (psv), bean leaf roll virus (blrv), bean yellow mosaic virus (bymv) and bean common mosaic virus (bcmv) in the major growing areas in the southeast and central regions of iran. samples were collected between may 2009 and march 2011 and analyzed for viral infection initial...

Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

In order to assess the occurrence, distribution and importance of viral diseases of mungbean and mashbean crops in Punjab, Pakistan, an extensive survey was conducted during summer season of 2004. The symptomatic plant samples were collected from farmer’s fields and experimental plots at research stations and tested by Enzyme-linked Immunosorbent Assay (ELISA) to detect and identify viruses inf...

Faba bean is a major grain legume widely cultivated in many countries.There are a large number of viruses damaging faba bean crop. In this survey, during 2011-2012 growing seasons, to determine the distribution of Bean yellow mosaic virus (BYMV), Bean common mosaic virus (BCMV), Cucumber mosaic virus (CMV), Tomato spotted wilt virus (TSWV) and Alfalfa mosaic virus (AMV), 630 samples were collec...
