Introduction

Rice ragged stunt virus (RRSV) is a plant pathogenic virus belonging to genus Oryzavirus that infects rice characterised by enations on leaves and leaf sheath, ragged leaves and stunting of plants.

Major Diseases

Ragged stunt disease

Geographical Distribution

Orissa, Tamil Nadu and West Bengal.

Particle Morphology

Polyhedral double shelled particles of about 65 nm in diameter that contains 10 ds RNA segments and 5-7 structural polypeptides.

Transmission Method

Transmitted by a vector; an insect; Nilaparvata lugens; Delphacidae in a persistent propagative manner; not transmitted by mechanical inoculation; not transmitted by seed.

Detection

ELISA and RT-PCR.
