Soybean mosaic virus

Family   : Potyviridae
Genus    : Potyvirus
Acronym  : SMV

Introduction

Soybean mosaic virus (SMV) is the most wide spread virus in many soybean growing areas. Besides aphid transmission the virus is also known to be transmitted via infected seeds. Rugosity, stunting, leaf curling, dark green vein banding, light green inter veinal areas, seed coat mottling , flower deformation, necrosis, some times necrotic lesions, systemic necrosis and bud blight are commonly observed.

Major Diseases

Mosaic

Geographical Distribution

Karnataka, Uttar Pradesh, Delhi and Madhya Pradesh.

Particle Morphology

Flexuous particles of 750 nm long.

Transmission Method

Transmitted by normally a vector; including Acyrthosiphon pisum, Aphis fabae, Myzus persicae; Aphididae in a non-persistent manner; transmitted by mechanical inoculation and also through seeds.

Detection

ELISA and RT-PCR.
