Groundnut yellow spot virus
Family : Bunyaviridae
Genus : Tospovirus
Acronym : PYSV
Introduction
Peanut (Groundnut) yellow spot virus (PYSV) infects ground nut causing yellow spots which later coalesce and become necrotic. It was identified as a distinct species under the genus Tospovirus based in serology and nucleotide sequence studies.
Major Diseases
Yellow spot

Particle Morphology
Pleomorphic virus particles of 80-120 nm in size and have surface projections composed of two viral glycoproteins
Transmission Method
Thrips, Scirtothrips dorsalis by persistent propagatvie manner
Detection
ELISA and RT-PCR
Host Range and Symptomatology
