Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Vigna mungo, V. radiata - faint yellow specks or spots and irregular blotching of tip leaves; slight leaf malformation.

Transmission

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae. Transmitted in a non-persistent manner. Virus not transmitted by mechanical inoculation; not transmitted by seed; not transmitted by pollen.

Ecology and control

Studies reported by two recessive genes for resistance identified in mungbean.

Geographical distribution

Spreads in Bangladesh, India, Pakistan, and the Philippines.
