Filamentous Viruses of Garlic in Argentina

Abstract

Filamentous viruses of garlic (Allium sativum) in Argentina were identified by the serological techniques of immunosorbent electron microscopy plus quantitative decoration, and enzyme-linked immunosorbent assay. The most widely grown cultivars, Rosado Paraguayo, Colorado, and Blanco, were sampled from different areas in which the crops showed mosaic symptoms. Most samples proved to contain mixtures of filamentous viruses, particularly onion yellow dwarf and garlic yellow streak (potyviruses), and a carlavirus (.)
