Three modern serological methods to detect plant viruses

 · Traditional diagnosis of plant viruses requires bioassay, an indior plant, determination of host range, symptomatology, virus particle morphology (size and shape), and vector relations [2,3]. A single diagnostic test or assay may provide adequate information on the identity of a virus but a combination of methods is generally needed which are specific, sensitive and inexpensive [4,5].

FUNDAMENTALS OF PLANT PATHOLOGY

FUNDAMENTALS OF PLANT PATHOLOGY (see Chapter 15 of 2000 WA/OR Sustainable Gardening) Plant pathology = the study of plant diseases (cause, development, control, etc.) Plant disease = a change in the normal structure, function, or development of a plant. What's so important about plant diseases? Diseases affect our food supply,, landscape, health (mycotoxins) and even our culture
